patch 9.0.1794: autoconf: not correctly detecing include dirs Commit: https://github.com/vim/vim/commit/74e1dada4199b2d9e68ccaafdb7895c85b4b08f1 Author: Illia Bobyr <illia.bobyr@gmail.com> Date: Sun Aug 27 18:26:54 2023 +0200 patch 9.0.1794: autoconf: not correctly detecing include dirs Problem: autoconf: not correctly detecing include dirs Solution: make use of python3 to generate includedirs configure: Python3: Use sysconfig for -I It seems better to use tools provided by Python for determining the include directories, rather than construct them "manually". Current system is broken when using virtual environments for python 3.11.4. It used to work before, but now it detects a incorrect value for `-I`. It would probably make sense to switch to a similar logic for lib folders, that is for the `-l` switch. There are also `sysconfig.get_config_h_filename()` and `sysconfig.get_makefile_filename()`, that could replace more Python specific logic in the current `configure{.ac,}`. sysconfig provides the necessary tools since Python 2.7. closes: #12889 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Illia Bobyr <illia.bobyr@gmail.com>
