From 6e050de4c01107ad0d914170aacf261701d2b71c Mon Sep 17 00:00:00 2001 From: David Bremner Date: Thu, 7 Oct 2021 08:59:06 -0300 Subject: [PATCH] configure: check explicitely for python dev (include) files As discussed at [1] we have received reports that the implicit check using cffi.FFI().verify() is not reliable in all environments. Since we already use pkg-config, and the python dev package should include a .pc file [2], add an extra check using pkg-config. On at least Debian, we have to know which version of python dev files with are looking for, so calculate that first.
