AX_PYTHON_DEVEL([version[,optional]])
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.
