dnl PANDORA_PYTHON3_DEVEL([version])

dnl DESCRIPTION
45
dnl
46
dnl Note: Defines as a precious variable "PYTHON3_VERSION". Don't override it
47
dnl in your configure.ac.
48
dnl
49
dnl This macro checks for Python and tries to get the include path to
50
dnl 'Python.h'. It provides the $(PYTHON3_CPPFLAGS) and $(PYTHON3_LDFLAGS)
51
dnl output variables. It also exports $(PYTHON3_EXTRA_LIBS) and
52
dnl $(PYTHON3_EXTRA_LDFLAGS) for embedding Python in your code.
53
dnl
54
dnl You can search for some particular version of Python by passing a
55
dnl parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
56
dnl note that you *have* to pass also an operator along with the version to
57
dnl match, and pay special attention to the single quotes surrounding the
58
dnl version number. Don't use "PYTHON3_VERSION" for this: that environment
59
dnl variable is declared as precious and thus reserved for the end-user.
