dnl Checks for Python and tries to get the include path to 'Python.h'.
|
|
dnl It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS) output
|
|
dnl variables.
|
|
dnl Also exports $(PYTHON_EXTRA_LIBS) and $(PYTHON_EXTRA_LDFLAGS)
|
|
dnl for embedding Python in your code.
|
|
dnl If the user wants to employ a particular version of Python, she can
|
|
dnl now pass to configure the PYTHON_VERSION environment variable.
|
|
dnl Should work for all versions of Python >= 2.1.0. You can disable the
|
|
dnl check for the python version by setting the PYTHON_NOVERSIONCHECK
|
|
dnl environment variable.
