From 81e2b198a8cb4ee5fdf108bd438f44b193ee3a36 Mon Sep 17 00:00:00 2001 From: John Snow Date: Wed, 10 May 2023 23:54:23 -0400 Subject: [PATCH] configure: create a python venv unconditionally This patch changes the configure script so that it always creates and uses a python virtual environment unconditionally. Meson bootstrapping is temporarily altered to force the use of meson from git or vendored source (as packaged in our source tarballs). A subsequent commit restores the use of distribution-vendored Meson.
