(This is necessary on e.g. AIX to use the # special cc_r/CC_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also to link with them as well.

If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments.

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. # # 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.
