Hi all! I have a Canon Powershot A95 digital camera. I want to move my pictures from the camera to my hard drives but I'm having some trouble: When I plug in the camera (through a USB) debian detects my camera and asks if I want to import my images. However, when I try to import nothing happens. When looking in usbview I see it detects my camera. I tried installing gphoto2 and running "gphoto2 -P" but what I get is: Code: Select allDetected a 'Canon:PowerShot A95 (normal mode)'. *** Error (-114: 'OS error in camera communication') *** For debugging messages, please use the --debug option. Please help me... | jazzman wrote: Code: Select allDetected a 'Canon:PowerShot A95 (normal mode)'. *** Error (-114: 'OS error in camera communication') *** For debugging messages, please use the --debug option. I'm not familiar with your camera, but with many models you must set your camera's 'USB Connect' to 'PTP', not the 'Normal' setting. |
I have a strange problem with my printer. It prints but in a strange way. When I go to localhost:631, add the printer and print a test page, it's OK. Then I can print from other applications too. But when I reboot, I can't print anything. Then if I go back to localhost:631 and modify the printer by specifying the PPD file and print a test page, everything works again until I reboot. How to fix? | Is there any reason why you are using the http://localhost:631 CUPS interface to configure your printer instead of the configuration tools provided in Gnome or KDE? What, if anything, didn't work in those tools? |
I'm trying to get a ncurses based application (ncmpc, a frontend for mpd) to display on a terminal running on a Palm PDA, connected by USB to a Linksys NSLU2 (slug). The terminal seems to work fine, but when I try this ncurses application, it doesn't quite work. Text characters seem to display ok, but the horizontal lines do not (I get funny text characters instead), and the screen scrolls up instead of staying still (if you know what I mean). I followed the advice here to get the Palm talking to the slug (very easy, but if anyone cares, the visor module works for the Palm, is already present and loads automatically in Debian, so ignore the stuff about the pl2303 module). And I use this line: Code: Select allgetty -h -L ttyUSB0 9600 vt100 to get a terminal, or this in /etc/inittab Code: Select allT0:23:respawn:/sbin/getty -h -L ttyUSB0 9600 vt100 (this last is best because the terminal is recreated every time you plug in the Palm) Both of these have the same result. So, my question is, does anyone know (or guess) of any tweaks I can perform at the slug end (ie those commands above), because there do not seem to be any options at the Palm end. You can change the baud rate and the flow control, but not the terminal type, and not much else. Specifically, is there a way of telling getty to create a terminal that is 32 characters wide and 16 rows high? I couldn't find anything in man getty that would allow you to specify the terminal size. And is there a way of sorting out the display of lines etc (ncurses stuff)? Should I try a different terminal type? Which one? I should say that the application works fine when I run it through an ssh terminal on another PC running linux (though I just realised that when I use PuTTY on a Windows machine I get the problem with lines etc, but not the problem that seems to be related to display size). It's not just about fonts, is it? Or character sets? I've only got one 'Charset' available on the Palm, called ISO-Latin1, maybe I just need a fixed-width font with ncurses characters in it? Anyone know anything about this stuff? Thanks Bernie | I found this, but I don't understand how to relate it back to the Palm. |

Can not get these devices to enable - except during install process. All else about install was success, I think.

hi there all - after lots of trials and tribulations i have switched from ubuntu to debian etch for a home server. i have installed etch base plus file and printer server packages from the cd and than installed webmin as it is headless. took me a while to get samba working - i'm kind of newbie to linux and it was a bit of a fiddle but now it works i want to share an external hard drive connected through usb (the machine is an old laptop and the internal hd is for system only) i can mount it through fstab using /dev/sdb1 and sdb2 etc but being usb when i will plug another hard drive it might reallocate the sdb numbers differently... few month ago i followed this article: http://howtos.linux.com/howtos/Flash-Me ... ml#hotplug to get it working on an older ubuntu but when i got to install hotplug it gave me a messege that my kernel-image will be removed or so i understood so i stopped... so how do i get debian etch to recognise the hd ids and mount by them rather than by sdb numbers? cheers michel | If the drive will always stay connected to you laptop you can safely use the /etc/fstab option, otherwise i am not sure how you could keep a persisitant mount of the drive as it *is* removable media. so my suggestion is keep it plugged in and always boot with the drive plugged in. maybe someone else a little more familiar with your issue can help you better. |

Hello everyone ! I really need help on this, and I fear it's a tough one. I recently installed Debian on my laptop through goodbye-microsoft.com (because my disk drive is dead and my motherboard can't boot from USB). The installation went well, as far as I can tell - I'm a complete newbie at Linux, so I can't be sure... I did set a root password in the installation process, one containing letters and numbers - at this point, my keyboard was recognized as a standard qwerty so I could type it correctly. Big mistake !! because when booting on the brand new Debian, I am warned of a bad XKB (which I understand means keyboard config), and I cannot type any numbers, meaning that I can't type root password, meaning... Well, I suppose you understand what kind of useless system the poor Debian turns into without root access on a fresh install. My laptop is an Acer Travelmate 2100 with French keyboard (azerty). When I press the number keys, with or without shift, with or without caps lock, all I get is [!,",#,'] and so on. I have Windows XP installed on another partition. Is there some way for me to fix the XKB ? (maybe through XP..?) Or do I need a complete reinstall ? Thanks in advance for the help. | Are you in X (Like KDE or Gnome)? If so, are you able to use the F keys? Can you use Ctrl-Alt-F1 to get into a terminal? If so you can log in as your user and check if the number keys work. Then, assuming they do work in the terminal, you can log in as root and run Code: Select alldpkg-reconfigure xserver-xorg to reconfigure X. I know there is a lot of 'if' but might be worth a shot.

Example (assuming that you build for the running kernel): # module-assistant a-i fglrx Now try to load the module by entering the following command as root: $ modprobe -v fglrx If everything goes well, modprobe prints the path of the module it loaded. The fglrx modules gets loaded. Changed my xorg.conf (changed vesa to fglrx and removed dri). With these settings xorg refused to start up.

I have a scanner that works fine when I am root, but when I'm a regular user xsane can't find the device. My user id is a member of the group scanner. I was able to use the scanner as a regular user if I chmoded /proc/bus/usb, but it is a pain to do this every log-in. My fstab line for proc is proc /proc proc defaults 0 0 Google hasn't been much help. I running etch with 2.6.12 kernel. Thanks in advance for any help. | I tried an experiment: I booted up without the scanner plugged into a usb port. After booting up I plugged in the scanner.

hi all, I have this problem with dvd, as described in subject line: I'm using 2.6.18-686 kernel with latest udev/hal/dbus from testing When I insert dvd-rom (debian installetion image) I can't mount it receiving the following error: "wrong fs type, bad superblock...." I've tried it with packages from unstable also, no change. When I tried to find the source of the problem I've seen that when I insert cd-rom into the drive udev sends two messages: 1. that the new removable device is available. 2. the label of the new media these messages are received by hal and hal on his side gets the size of the newly inserted media from somewhere else (don't know from where yet) Thus allowing me to mount the cd-rom manually using mount or automatically through hal. However when I insert dvd into the drive, the messages from the udev are: 1. New removable media available 2. size of the new media 3. label The size that is reported by udev in this case is always 1f70hex (8048) regrdless of the dvd that is inserted. Hal sets the size of the media according to what he receives from udev, however in theory the hal's reported size should matter only to services that use hal. When I try to mount such dvd, I get error: "Wrong fs type or bad superblock...." kernel logs shows error: "bad superblock, trying to access beyond media boundries..." Which is understandable because of the wrong size that is being used. Disabling hal/dbus doesn't have any effect. Searching this and other forums I've got an impression that maybe other users experiencing the same problem, they just haven't found the source yet. Because of the problem appearing on 2.6.17 and 2.6.18 kernels I believe that the bug (if it is a bug) most probably in udev, however the only version available from repo's is 100 from testing, so I can't try another version. Can any one help me or point me in right direction of what to do to resolve this? The drive is nec ide dvd writer and is the only ata device. Thanks in andvance. | Well, I'm sorry I was too quick to blame After searching some more I've found on some mailing list a user describing the same exact problem with same exact kernel/udev messages with same exact dvd writer model: NEC 3550A. Apparently he discovered that his dvd was broken (laser burnt out), well after switching to other dvd drive I can mount dvd's again, so apparently my dvd writer is broken also Which is too bad cause a week ago its warranty period ended. |
Just installed Sarge. Every thing works. Except printing. Set up printer in CUPS through both my browser and the KDE CC.

After an upgrade of my Etch system the newest cups (1.2.1-3) was installed and I can no longer print. Test pages via localhost:631 work, but when printing the printer list can't be retrieved because of a failed connection to cups server. Googling around I find some bug reports, but no work arounds. My printer (HP 5940) is on another linux system connected to a local network. Are there any simple ways to go back to an earlier version of cups? Or does anyone know a way around this?

I recently bought a Game-Elements GGE909 Controller at walmart (yeah 15 bucks). When I got home, i plugged it in and it worked fine in Windows (of course) and on my Ubuntu partition. I recently installed Debian because Ubuntu runs pretty slow on my laptop, but I can't get that controller to work in Debian. It doesn't even seem to be detecting the joystick. help please? | USB is still a bit of a black art, I've found... What is the output of Code: Select alllsusb when the thing is plugged in?

Hello everybody ! I have a problem making my webcam work in debian... I've read a lot of forum posts but nothin' worked ... I'm using debian testing with kernel 2.6. 2.6.15-1-686-smp The webcam is a creative webcam (seems to use ov511 driver and recognized as a ov518) I installed gqcam, the command gqcam -v /dev/video0 returns : "/dev/video0: Function not implemented" I loaded videodev ovcamchip and ov511 compress=1 modules as I read on a forum... here's the console output returned by grep | dmesg ov5 : drivers/usb/media/ov511.c: USB OV518 video device found drivers/usb/media/ov511.c: Device revision 17 drivers/usb/media/ov511.c: Sensor is an OV6620 drivers/usb/media/ov511.c: Device at usb-0000:00:1d.3-1 registered to minor 0 usbcore: registered new driver ov511 drivers/usb/media/ov511.c: v1.64 for Linux 2.5 : ov511 USB Camera Driver drivers/usb/media/ov511.c: No decompressor available drivers/usb/media/ov511.c: No decompressor available drivers/usb/media/ov511.c: No decompressor available drivers/usb/media/ov511.c: No decompressor available note : i tried to load pwc driver too.... note : i tried to load ov511 module without compress=1 too... note : using udev, kde with dual display on ATI,(all full suported) Please someone rescue me !

Thanks a lot for your time... ask for any additional infos... -simon | I can't help specifically, but perhaps I can offer a few ideas... Which version of the driver are you using? For the OV6620 senser you'll need the later 2.x series. Check the permissions on your /dev/video0 (you need r+w permission) There may be a problem if you're using a newer version of gcc than the kernel was compiled with. And here is a tidbit poorly translated from french using babelfish: Note: With cool thing to C is to cuts the ov519_decomp loaded after each time you load the ov51x module. With kernels 2.6, it is really easy: all you cuts to C is to could has text file At /etc/modprobe.d that has this line: ' install ov51x /sbin/modprobe -- is unaware of-install ov51x; /sbin/modprobe ov519_decomp'. To C so, just C the following things: # echo "install ov51x /sbin/modprobe -- is unaware of-install ov51x; /sbin/modprobe ov519_decomp "\ > /etc/modprobe.d/ov51x # update-modules (The \ is only to tell that the two lines cuts to Be typed in A row.. It would not drank made the here page wink ) Note: To work around the kopete for KDE 3.5 green image bug, you should add this parameter: /sbin/modprobe -- is unaware of-install ov51x force_palette=13, see FAQ for more details. Note: Here, debian sid, this does No to skirt seems to work.. Instead it worked adding the same line to /etc/modprobe.conf |
I have been trying to install the FGLRX drivers for my computer, following the instructions here: http://wiki.cchtml.com/index.php/Debian ... tion_Guide.

Hi all I've just used the Etch installer (2.6.12) from the netboot cd to install Debian on my new computer. It's got an ASUS A8N-VM CSM motherboard, and a Seagate SATA 7200.9 hard disk drive. When installing, it couldn't detect the disk automatically, but it worked fine once I'd told it to use the sata_nv module. The rest of the installer went without a hitch, and I've now rebooted. When starting the system, it encounters a kernel panic: Code: Select allpivot_root: No such file or directory /sbin/init: 432: cannot open dev/console: No such file Kernel panic - not syncing: Attempted to kill init! There's quite a bit more above that too, but I'm typing it out by hand as I can't get into the system. Let me know if more detail is needed, but I can only read the last screenful. I've also tried adding this line to the GRUB booting commands, between the "kernel" and "initrd" lines: Code: Select allmodule /lib/modules/2.6.12-1-amd64-generic/kernel/drivers/scsi/sata_nv.ko ...and I've tried this too (note the "lib64")... Code: Select allmodule /lib64/modules/2.6.12-1-amd64-generic/kernel/drivers/scsi/sata_nv.ko ...but neither of them made any difference. Does anyone know what to do to solve this? Somebody must've installed successfully on this motherboard! Thanks! | try debian etchamd64 lists and nvnews forums for news and tips. Good luck. |
Hello there i am running etch (including a cool kde 3.5 and a 2.6.15-1 kernel) and really, really like it but here is the issue; i have a nvidia mx440 geforce 4 64 mb card. Before etch, (when i was running xandros 2.0, ubuntu 5.04-5.10, debian sarge et al.) and needed an nvidia driver i was either downloading the nvidia-glx package+dependencies or getting headers for my kernel the build-essentials and fakeroot packages and then compiling the tar.gz driver form nvidia website. Now with etch and the default 2.6.15-1 kernel and the transition to Xorg, nvidia glx does not apply; it is not installable via synaptic due to dependency problems the default libmesa driver is supposed to replace it but 3d acceleration is not good (enen 3d billard is very slow) so i was wandering if there is any way getting round it apologies for the lenghty post Regards | Download the driver from http://www.nvidia.com/content/drivers/drivers.asp and install it(you will need kernel headers(linux-headers-2.6.15)). |

For some background, I've recently moved from Ubuntu server to Debian, something I've wanted to do for some time. The server is purely for home use, and runs Jellyfin, TVheadend and Samba.

Try another one." fi done ## this grabs the file name you selected file=$opt ##This searches for the .java file to see if it exists ##This is unneeded but is here being its working code i can use in the future search_dir= "" ##put your dir here file_name=$file if [[ -d "$search_dir" ]]; then if [[ -f "$search_dir/$file_name" ]]; then echo "File $file_name exists in directory $search_dir." else echo "File $file_name does not exist in directory $search_dir." fi else echo "Directory $search_dir does not exist." fi ##This searches for the .class to see if it exists fileClass=$opt fileClass=${fileClass//.java/} fileClass+=".class" if [[ -d "$search_dir" ]]; then if [[ -f "$search_dir/$fileClass" ]]; then echo "File $fileClass exists in directory $search_dir." && classExists="y" else echo "File $fileClass does not exist in directory $search_dir." && classNotExists='y' fi else echo "" fi ##This next segment needs to be edited so if .class does not exist it compiles and then does java $file ##Compiles code if class does not exist if [[ "$classNotExists" = "y" ]]; then cd $search_dir && javac $file; sleep 1 && cd $search_dir && java $file; ##has not been tested fi ##Compiles the code if you say yes if [[ "$classExists" = "y" ]]; then echo "would you like to recompile the java code? y/n" read -r Answer fi if [[ "$Answer" =~ [yY] ]]; then cd $search_dir && javac $file; java $file fi ##Just runs the code if you say no if [[ "$Answer" =~ [nN] ]]; then cd $search_dir && java $file && java $file fi | The problem is a simple mistake: = assigns a value, == is a comparison operator.

Hi Everybody This is a piece of code that compile as well and true by Tiny C Compiler ( tcc ) every time ..... But a week ago version of GCC was 12.2.0-14 and now 12.2.0-3 and both of them compile it wrongly and give garbage values most of times ( and correctly , some times ) . The Code : Code: Select all#include <stdio.h> int main() { FILE * fp = fopen("/home/lovelorn/Pictures/post-3.jpeg", "rb"); int n; for (int i = 0; i < 100; i++) { fread(&n, 1, 1, fp); printf("%d ", n); } fclose(fp); return 0; } You can replace the file with any file You want instead . But GCC compile and link it wrongly ...... GCC must be upgraded in Debian 12 Bookworm ...... I update and upgrade regularly ...... Can anyone report it to Debian bugs ?

I have just completed a course on programming with C++. (Unfortunately, we did almost exclusively use the command line and only very briefly did extremely basic UI examples using Qt Creator. And since I prefer the look and feel of GTK+ over Qt I thought I should better learn how to create interfaces I do actually prefer.) Therefore, I want to create my first own small C++ project using GTK4. To get there, I try to work my way through the official gtkmm documentation. Unfortunately, in chapter 17 I discovered that Debian stable includes gtkmm 4.8 while some examples in the documentation need at least version 4.10 to work. I usually try to stick with the versions provided by Debian stable to keep everything reliable and simple. But since I am learning something new it doesn't seem sensible to start with learning a deprecated standard. According to my findings before GTK4 Glade was the go-to solution for creating user interfaces with GTK+ but at the moment development looks like a transitional state where Glade isn't really workable with GTK4 applications and Cambalache doesn't seem to be ready for general use yet. (So far it isn't part of Debian anyway.) I am surprised how hard it is for me to understand gtkmm. I am not sure if my current approach of trying to learn to write all necessary code for GTK4 using gtkmm by hand is a sensible approach. I have already encountered examples where I failed to adapt or combine functions from different examples. (I can't even predict what methods and properties I should expect in Glib or GTK.) I am clearly missing some foundational understanding on how concepts in GTK do really fit together and muddle through trying to understand as much as possible on the way. This isn't an approach I feel very comfortable with. Maybe I am wasting a lot of time by messing with things I shouldn't even attempt yet. Maybe GTK was not the best choice to be used in my first C++ project because it is tailored towards C and since gtkmm is only a wrapper for C++. But I have already invested weeks in it and at least by now it is probably less confusing if I stick with it. On YouTube I found someone who seems to have found a way to still use Glade to create GTK3 UI files which he then converts to GTK4. If possible I would like to avoid such a workaround. I wonder how you experienced developers out there would approach this hurdle. Do you figure it would be sensible for me as a C++ beginner to switch to Debian testing and at least get gtkmm version 4.10? Would you recommend compiling Cambalanche from code and start working with it right away? Do you know of any more basic guide for learning GTK4 GUI development with C++? Unfortunately, my track record of resolving issues by consulting the GTK documentation has not been great so far because without examples I rarely understand how exactly properties and methods even need to be written in code. | Can't actually help with gtkmm. I use Perl as my favourite programming language and there are a couple of tutorials and sample programs for GTK available in the internet. Recently, being frustrated and confused by the official documentation, I eventually asked chatGPT how this and that works and it almost always gave me well explained and running example programs. Just ask chatGPT "linux what is gtkmm". With this question (asked in German), it gave me a sample program of about 50 lines written in C++ with good explanations in English. As I don't use C, I did not try to compile it. I used glade as a GUI builder before, but for writing small tools it is way too rich and complicated and several items seem to be missing. I found it not necessary to use such tools. Writing the source code by yourself is easy enough (at least in Perl ) For me, the problems in writing GTK applications was not that much GTK itself but rather how to handle the event driven logic. |
Hi, I am currently running Debian 12 Bookworm. Using Discovery, I installed Qt Creator 9.0.2, based on Qt 6.4.2 (GCC 12.2.0, X86_64). On trying to use the IDE i find that a lot of the entries in the top menus just don't show up. (I'm using the Breeze Dark theme.) A lot of the items in the menus and sub-menus are blacked out, with the (sub)menus appearing as just black rectangles. Mousing over the (sub)menus illuminates only those items that have a small right-pointing arrow head at the end of the item line. Finally, the text in the (pre-filled) text boxes shows up as black text on a slightly less black background. EDIT: One thing I forgot to mention is that, when I try to set up a "Hello World" program, the IDE gets as far as showing the dialog that allows "kits" to be selected. It appears(!) that the "Desktop" kit has been pre-selected. However, this would seem to be contradicted as the "Next" button at the bottom of this dialog is greyed out. Does anyone know why this version of Qt Creator has so much functionality missing/disabled/whatever ? Also, is there a way to install the missing kits and re-enable this missing functionality and to change the text from black to white on a black background ?

Hello, It would be interesting to get a list of packages in Debian repositories that contain firmware files with the detail of repository content and package name. I haven't found a single command in existing packages to do this. It would also be useful to know the repository section where they are stored, as this is an indirect indication of the licence they are distributed under. Here is my 2 cents for a simple bash script to do this, based on existing commands: Code: Select all#! /bin/sh # # A simple script to list pacakges whose names contain the patter "firmware" # # It prints three columns (sorted alphabetically): # 1) repository component (main, contrib, non-free, non-free-frimware) # 2) repository section # 3) name of the package # # All repository components must be configured in /etc/apt/sources to be scanned. apt list "*firmware*" | awk -F '/' '{print $1;}' | \ while read F do apt show $F | grep "APT-Sources:" | awk -F " " '{printf("%-30s ", $3) ;}' apt show $F | grep "Section:" | awk -F " " '{printf("%-30s ", $2) ;}' echo $F done | \ sort If it is named firmware.sh, it can be called this way: Code: Select all./firmware.sh 2>/dev/null I post it here for comments, suggestions and improvements. | Hello @fabien, Thank you so much for your feedback. You have used the potential of the bash and awk languages in a very interesting way. Perhaps it would be of interest to many forum readers to briefly explain what you think is most important for the casual bash script writer. The speed optimization of the revised scripts is impressive compared to the script I originally posted (stats from time and wc commands): scriptrun timelineswordsbytes original (bash+apt+awk+grep)0m59.591s19104695 revised (bash+apt)0m1.080s291481061 revised (bash+awk)0m0.694s31991223 -- note: I suspect that the way the wc command calculates the number of words is biased because it does not interpret the code syntax. |
Hi, I am trying to learn C programming making use of GTK 3. I am trying to work through the book "C and GUI Programming" 2nd edition, by Simon Long, pdf freely available from the MagPi magazine website, https://magpi.raspberrypi.com/books and published under a Creative Commons license. However, I have hit a snag with trying to get gcc to recognise GTK. When I try to compile the first small program using Code: Select allgcc gtktest.c `pkg-config --cflags --libs gtk+3.0` -o gtktest the system responds with Code: Select all$ gcc gtktest.c `pkg-config --cflags --libs gtk+3.0` -o gtktest Package gtk+3.0 was not found in the pkg-config search path. Perhaps you should add the directory containing `gtk+3.0.pc' to the PKG_CONFIG_PATH environment variable Package 'gtk+3.0', required by 'virtual:world', not found gtktest.c:1:10: fatal error: gtk/gtk.h: No such file or directory 1 | #include <gtk/gtk.h> | ^~~~~~~~~~~ compilation terminated. So far, I have learned that :- a) I need to set up some kind of .pc file to be used with the PKG_CONFIG_PATH environment variable; b) there is a gtk-3.0 folder in /usr/share; c) there is a pkgconfig foler in /usr/share. What do I place inside this .pc file ? Am I correct in thinking that I place the .pc file within /usr/share/pkgconfig folder ? I found a video on YouTube, "Understanding pkg-config command in Linux|Include and Link OpenCV header and library" but this did not show how to make changes to the PKG_CONFIG_PATH environment variable. As this is the first time that I have had to do this, could someone please point me in the direction of a good video/tutorial that will help me get this "stitching together" set up properly, including where to find this PKG_CONFIG_PATH environment variable ?

Note: It seems to me that on page 79 of the book [1], the author missed the "-" character in the name of the library "gtk+-3.0" in the text of the paragraph, while the "-" is correctly displayed in the screen image on the same page.

Hello I need to process files' data for my application , When it comes to huge data , C language can't handle them and I must write my own library for huge numbers and data but GMP is a good choice for this manner . Also I need functions for reading/writing sectors of HDD or SSD as huge amount of data for my application . I write this piece of code by GMP manual but it writes only " 0 " and as ASCII ( text ) ..... Is there any way to read/write files and sectors as binary and also my code doesn't work ( 0 as result ) : Code: Select all#include <stdio.h> #include <gmp.h> int main(void) { FILE * fr, * fw; // two file pointers prepared for creation char filename[100]; // a string for file name of input and output files printf("Enter file's name : "); scanf("%s", filename); // taking file name of input fr = fopen(filename, "rb+"); // opening file fr for reading as binary printf("Enter copied filename :"); scanf("%s", filename); // taking file name of output fw = fopen(filename, "wb+"); // opening file fw for writing as binary mpz_t x; // a big integer decalred mpz_t y; // also y mpz_init(x); // initialization of x to 0 mpz_init(y); // also y gmp_fscanf(fr, "%Zd", y); // file scanning of input file as huge decimal and store it in y mpz_set(x, y); // assigning y in x --- or should it be as a must an explicit number and not variable ? gmp_fprintf(fw, "%Zd", x); // writing x to a file mpz_clear(x); // clearing and emptying x mpz_clear(y); // also y fclose(fr); //closing fr fclose(fw); // closing fw return 0; } | It looks like you open "filename" to read ("rb+", note that "b" is ignored, so "r+" would suffice), and then immediately you open *the same file* to write ("wb+"). When you open a file for writing, the file is *truncated*, so when you then read data (anything, your issue is not specific to mpz) you get nothing. Learn C and Posix. Try first with normal integers (to avoid xy-problems), and once you get it working, switch to mpz. |

For example, the source package named "samba" [1] generates the binary code for the C function named "remote_password_change" with the following prototype: Code: Select allNTSTATUS remote_password_change(const char *remote_machine, const char *domain, const char *user_name, const char *old_passwd, const char *new_passwd, char **err_str); Fetch -dbgsym packages for all of the binary packages generated from the source package. Then use "nm" to list symbols in those binaries? This still won't help if the function got inlined though. I followed your hint: 1) I configured /etc/apt/sources.list to add debian-debug repositories: Code: Select alldeb http://deb.debian.org/debian/ bookworm main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian bookworm main non-free-firmware deb http://deb.debian.org/debian bookworm-updates main non-free-firmware deb-src http://deb.debian.org/debian bookworm-updates main non-free-firmware deb http://deb.debian.org/debian-security/ bookworm-security main non-free-firmware deb-src http://deb.debian.org/debian-security/ bookworm-security main non-free-firmware # Debug Symbols deb http://deb.debian.org/debian-debug/ bookworm-debug main contrib non-free non-free-firmware deb http://deb.debian.org/debian-debug/ bookworm-proposed-updates-debug main 2) Using the Debian site at https://packages.debian.org , I searched for the Debian source package of the samba binary package: https://packages.debian.org/search?keywords=samba&searchon=sourcenames&suite=stable§ion=all I obtained the following output: Source Package samba bookworm (net): 2:4.17.12+dfsg-0+deb12u1 [security] Binary packages: [hide 26 binary packages] ctdb, ldb-tools, libldb-dev, libldb2, libnss-winbind, libpam-winbind, libsmbclient, libsmbclient-dev, libwbclient-dev, libwbclient0, python3-ldb, python3-ldb-dev, python3-samba, registry-tools, samba, samba-ad-dc, samba-ad-provision, samba-common, samba-common-bin, samba-dev, samba-dsdb-modules, samba-libs, samba-testsuite, samba-vfs-modules, smbclient, winbind 3) I copied, pasted and manually edited all the names of the binary packages built from the source package named "samba". Then, I assembled the following command (a simulated install) replacing the ',' character from previous output with "-dbgsym" (all symbols packages created by Debian project use the "-dbgsym" suffix): Code: Select all# apt -s install ctdb-dbgsym ldb-tools-dbgsym libldb-dev-dbgsym libldb2-dbgsym libnss-winbind-dbgsym libpam-winbind-dbgsym libsmbclient-dbgsym libsmbclient-dev-dbgsym libwbclient-dev-dbgsym libwbclient0-dbgsym python3-ldb-dbgsym python3-ldb-dev-dbgsym python3-samba-dbgsym registry-tools-dbgsym samba-dbgsym samba-ad-dc-dbgsym samba-ad-provision-dbgsym samba-common-dbgsym samba-common-bin-dbgsym samba-dev-dbgsym samba-dsdb-modules-dbgsym samba-libs-dbgsym samba-testsuite-dbgsym samba-vfs-modules-dbgsym smbclient-dbgsym winbind Reading package lists...

They are "-dev" packages, while the others packages I suppose don't contain libraries or executable code, therefore I suppose they could not supply debug symbols. 4) I modified the previous simulated command, removing references to not existing "-dbgsym" packages: Code: Select all# apt install ctdb-dbgsym ldb-tools-dbgsym \ libldb2-dbgsym libnss-winbind-dbgsym libpam-winbind-dbgsym \ libsmbclient-dbgsym libwbclient0-dbgsym python3-ldb-dbgsym \ python3-samba-dbgsym registry-tools-dbgsym samba-dbgsym \ samba-common-bin-dbgsym samba-dsdb-modules-dbgsym \ samba-libs-dbgsym samba-testsuite-dbgsym samba-vfs-modules-dbgsym \ smbclient-dbgsym winbind 5) I searched for the name of the C function named "remote_password_change" (using the nm package you advised to me) in debug symbols (note: "-dbgsym" packages store their "*.debug" files in the directory named /usr/lib/debug/ ) Code: Select all# find /usr/lib/debug -name "*.debug" -exec nm --print-file-name --line-numbers {} 2>&1 \; | grep "remote_password_change" It took about 6 minutes; the output was: Code: Select all# find /usr/lib/debug -name "*.debug" -exec nm --print-file-name --line-numbers {} 2>&1 \; | grep "remote_password_change" /usr/lib/debug/.build-id/db/feab433239b8e04dcce44968d70346ac03571a.debug:0000000000005830 T remote_password_change ./bin/default/../../source3/libsmb/passchange.c:37 Now I missing the last step: how can I tell which Debian binary package and binary executable (program) the following file refers to? Code: Select all/usr/lib/debug/.build-id/db/feab433239b8e04dcce44968d70346ac03571a.debug Is there a smarter way to do all this? |

Won't go into the long winded reason, but I'm looking for a C++ http/REST library to create a management interface to a daemon I've been working on. not so concerned about SSL support as I am in "correct and proper" implementation of socket handling, URL parsing, and conformant document generation. The only real security I'm implementing is an authentication hash as one of the GET request params. Any recommendations? | crickets chirping, so I guess no recommendations. Writing the client side of such a service is a no brainer. I'm looking for a c++ class set that supports the server side: tcp connection managment/listenner, parsing of URLS, rudimentary document creation of html or json. couldn't care less about websockets protocol or SSL. Just interested in basic HTTP REST functionality. |

I am trying to modify an epub file that uses image files instead of accented letters. I am replacing the images with unicode characters. In order to do this I need to perform a find and replace on a regex matching the image tag, from the opening angle bracket to the closing one. However, consider the following: Code: Select all<img alt="image" src="c0011-01.jpg"/>s</strong> because the <strong>mi</strong> is short, but <strong>a-m<img alt="image" src="c0007-01.jpg"/>-tus</strong> because the <strong>m<img alt="image" src="c0025-01.jpg"/> I want to target the image tag containing c0007-01.jpg but it is flanked by two other image tags. Any regex I have tried targets from the first image tag (c0011-01.jpg) to the third c0025.jpg). I need a regex that: starts at the "<" and ends at the ">" (so I can execute a find and replace cleanly) must contain c0007-01.jpg does not contain any additional "<" within If I have a regex that fulfills the above criteria, I'm fairly sure that it will only target the tag I want.

SOLUTION My Bash idiom was immature. Scripting in Bash apparently requires some different habits than entering commands interactively on the command line does. For example, it requires that one terminate command-line options using '--'. It requires that one prefer printf or <<< rather than echo in some circumstances. It requires a clear understanding of the eval builtin. It requires lots of things. In general, Bash has ways of escaping various possible misinterpretations of text, for example via the aforementioned '--' and eval, not to mention quoting. Most of these ways are unfamiliar to Bash command-line users (or at any rate, they were unfamiliar to me), so they must be learned—and, once learned, must frequently be employed. Coming from C++, I had not been used to escaping everything, like this: Code: Select allrun_by_batch wget_insist "'"'-nc -x -nH --cut-dirs=4 -P '"'"'"'"'"'"'"$TARGET/pool"'"'"'"'"'"'"' --'"'" It actually makes some sense once one thinks about it in the right way, but it's a little hard to get used to. Bash lacks programming support for long scripts, but support is for scripts longer than about 3000 lines. A decent programmer can work without support up to that length, so lack of support was not my problem. My problem was immature Bash idiom. Bash scales poorly when idiom is immature. I suppose that there is no good remedy for immature scripting idiom other than writing a few thousand lines and failing at it, while occasionally seeking advice. The various advice others have given below has helped. ORIGINAL QUESTION In your opinion, how practical is it to write complex Bash shell scripts that handle offbeat filenames and pathnames like, say, 'My Files/-Preferences:(3)'? I realize that it is possible to write such scripts, but every time one mixes various quoting and expansion mechanisms like (say) echo ${X}{1,2} | sed "s/${A}/${B%$C}/" or uses eval or the like, Bash—or various command-line tools invoked from Bash—seems to remind one how much it dislikes offbeat filenames. The script on which I am now working is a moderate 1500 lines or so in length, yet I have spent so many hours tracking down obscure bugs due to quoting and expansion issues that I am thinking of having the script simply reject all unconventional pathnames. Some users won't like that. Meanwhile, I feel that I am fighting Bash. I would instead like to work with Bash, and I would prefer not to give up on Bash just because some users have ported Microsoft-style file-naming habits to Debian. Is there an easy way to do this? What am I missing, please? | It of course depends on what you're trying to do. What are you trying to do anyway? :) Normally you don't need to manipulate file names, you just pass them to a program, etc. and as long as they're quoted ("$NAME" instead of $NAME), there's usually no problem. But yes, the general idea is that everything is text, so a command line is parsed as text, commonly separating tokens by spaces, which may be a problem. I hear Powershell is more "object oriented", but everytime I see a Powershell script I think something is deeply wrong with the concept, and seems only OK for programming but not for an interactive shell. So, again, what are you trying to do? maybe there's an easier/simpler way. |

I'm trying to use qsort() to sort a table with 5 entries in it (room for 100) in a program. I've verified that the data in the table is valid when I call qsort(), but afterwards, there is nothing but trash there. I'm programming in C using gcc. I've used qsort() successfully many times before under Turbo C, but this is the first time for gcc. One difference is that Turbo C uses 2-byte short ints, but gcc uses 4-byte short ints. I thought gcc might be inserting slack bytes in the ELEMEN structure, but I added the ((packed)) attribute and this did not fix the problem. Perhaps my call to the qsort() function is wrong. This particular problem is not mentioned on the internet. I checked the syntax of the call to qsort() there and it seems to be correct. There's nothing else to check there.

I have this C program, and I keep getting compile warnings. (The entire program is thousands of lines long, so I can't post the whole thing -- but I'll include all the relevant parts.) The problem occurs when one structure, TPARAMS, points to another structure, XUNDO2, and that structure points to a short table, xnewstep[], which points to yet another structure, ELEMENT. But the pointer to XUNDO2 can also point to XUNDO1 or XUNDO3, so it is defined as a void* pointer. Since THAT pointer is NOT defined as struct XUNDO2*, the compiler doesn't know where to find the xnewstep table. I want to use a type cast to say, in this case, the pointer indeed points to an XUNDO2 structure. Code: Select allstruct XUNDO1 {struct ELEMENT* xnewstep[9]; struct ELEMENT* xoldstep[9]; char xvalue[9];}; struct XUNDO2 {struct ELEMENT* xnewstep[9];}; struct XUNDO3 {struct ELEMENT* xpostreq[100];}; struct TPARAMS {short int action; char kind; char newtsnum[6]; char newstat; struct ELEMENT* newtask; struct ELEMENT* oldtask; struct ELEMENT* addpoint; struct ELEMENT* topstep; struct UNDO* unthing; void* /* points to the extended undo area; this could */ xthing;}; /* be the structure XUNDO1, XUNDO2, or XUNDO3 */ struct ELEMENT {struct ELEMENT* chain1; struct ELEMENT* chain2; struct ELEMENT* chain3; short int duetime; short unsigned int duedate; char status; char priority[2]; char tasktype; char tasknum[4]; char stepnum; char descript[2];}; void edittask(struct ELEMENT* origtask) {struct TPARAMS t; . . . {t.oldtask = ((struct XUNDO2*)t.xthing)-> xnewstep[i]; /* WORKS FINE */ . . . baseopts(&t); . . . void baseopts(struct TPARAMS* t) . . . {addopts(descbuf, t); . . . void addopts(char descbuf[], struct TPARAMS* t) . . . {if ((struct XUNDO2*)t-> xthing-> xnewstep[s] != 0) break;}; . . . The last line of code above, with the break keyword, is the one that has the problem. When I compile this, I get Warning . . . 'xnewstep' not part of structure in function addopts . I want to be able to use the type cast "(struct XUNDO2*)" to let the compiler know I'm pointing to an XUNDO2 structure -- but I can't seem to figure out exactly where to put it. I can work around this problem by assigning t-> xthing to a temporary variable then type casting that, or by redefining xthing as a struct XUNDO2* variable. But either of these solutions would reduce the readability of the program. I've googled type casts and pointers, but nothing I found covers this exact situation. I'm using Turbo C and running the binary under DOSBox under Debian Stretch with the MATE desktop. (Later on, I will rewrite this in a more modern language.) But if someone can give me a syntax that works under gcc, I'll accept that as solution to the problem. Caitlin | If I understand correctly, then "t-> xthing" should be the pointer to the XUNDO2 structure. My knowledge of C is getting a bit rusty, but inserting a pair of parentheses should help, then: Code: Select all{if ((struct XUNDO2*)(t-> xthing)-> xnewstep[s] != 0) break;}; |

Sorry, for asking such a probably very trivial question but I am stuck and so far I am unable to find an answer. I want to apply a patch to a free cpp project I am helping out with as a designer. Somebody provided a .patch file and I expected it would be easy to just do: "$ patch < file.patch" if I am in the right folder on Debian stable. But I get "bash: patch: command not found" as a result and I can't find "patch" as a package in Debian either. So far I was unable to find any hint how I could actually use the patch command on Debian. Everywhere it just seems to be assumed that the patch command works out of the box. Obviously I am missing something here. Can anyone enlighten me? | The "patch" command is provided by the "patch" package. Are your package sources configured properly ? Code: Select allapt-cache policy patch |
I am not so good in bash, so I have simple question. I have some music in ALAC (m4a) files, distributed in sub directories (albums). I want to convert them in FLAC. I am trying something like this: Code: Select allfor i in */*.m4a; do ffmpeg -i "$i" ${i%m4a}wav; done to convert them in WAV format, but expansion */*.m4a is not working, I get the error message from ffmpeg that */*.m4a does not exist. How to solve the problem with expansion? | You should use find to navigate through subdirectories. However, there is a very good Bash script out there for converting various sound files to flac: https://www.legroom.net/software/convtoflac I suggest you download it and study it. It's safe to use, by the way: I use it almost daily. |
Hi, Do you know How do i get this: rsync --delete --max-size=20M /source /target this, only works once.. when i update max-size, delete option doesnt purge target files bigger or smaller than "max-size"... Its very strange, it obligates me to delete all target files before i want to sync filtering by size file in order to work properly .. Right now, I have it this way working like I would like it..(I had to use hardlinks to prevent all files being copying each time, cos I need a first delete.) Code: Select allrm -R "$pathvideoshort/"* rsync -av --delete --max-size=12M --link-dest="$pathvideos/" "$pathvideos/" "$pathvideoshort/" Thanks a lot. | Do you believe that --delete affects --max-size? Please read, and try to understand, the fine rsync manual. Code: Select allman rsync |
