From f0f93a7adfee49604c37d4ff675e50ad5dc197cb Mon Sep 17 00:00:00 2001 From: Dmitry Kozlyuk Date: Sun, 24 Jan 2021 23:51:56 +0300 Subject: [PATCH] buildtools: use Python pmdinfogen Use the same interpreter to run pmdinfogen as for other build scripts. Adjust wrapper script accordingly and also don't suppress stderr from ar and pmdinfogen. Add configure-time check for elftools Python module for Unix hosts. Add pyelftools to CI configuration and build requirements for Linux and FreeBSD. Windows targets are not currently using pmdinfogen. Suppress ABI warnings about generated PMD information strings.
