When we are using compiled languages – we are usually depending on pkg-config files. For example, “PKG_CHECK_MODULES(GLIB, glib2)”, but what if we are using Python?
Autoconf Archive has AX_PYTHON_MODULE macros. We can use it very easy.
How about Python + GObject Introspection? Let’s take GTK+ as an example. I wrote special m4 file (see below), you can place it in “m4” directory. Then you just need add “AX_PYTHON_GI(Gtk, 3.0)” into “configure.ac” and autoconf will check if GI works and Gtk-3.0.typelib is usable.
P.S. note that I’m not m4 expert, but it works for me.
