| # SYNOPSIS | |
| # | |
| # AX_PYTHON_DEVEL([version[,optional]]) | |
| # | |
| # DESCRIPTION | |
| # | |
| # Note: Defines as a precious variable "PYTHON_VERSION". Don't override it | |
| # in your configure.ac. | |
| # | |
| # This macro checks for Python and tries to get the include path to | |
| # 'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LIBS) output | |
| # variables. It also exports $(PYTHON_EXTRA_LIBS) and | |
| # $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code. | |
| # | |
| # You can search for some particular version of Python by passing a | |
| # parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please | |
| # note that you *have* to pass also an operator along with the version to | |
| # match, and pay special attention to the single quotes surrounding the | |
| # version number. Don't use "PYTHON_VERSION" for this: that environment | |
| # variable is declared as precious and thus reserved for the end-user. | |
| # | |
| # By default this will fail if it does not detect a development version of | |
| # python. If you want it to continue, set optional to true, like | |
| # AX_PYTHON_DEVEL([], [true]). The ax_python_devel_found variable will be | |
| # "no" if it fails. | |
| # | |
| # This macro should work for all versions of Python >= 2.1.0. As an end | |
| # user, you can disable the check for the python version by setting the | |
| # PYTHON_NOVERSIONCHECK environment variable to something else than the | |
| # empty string. | |
| # | |
| # If you need to use this macro for an older Python version, please | |
| # contact the authors. We're always open for feedback. | |
