Describe the issue

Since !33634 (merged) ( bisected to 906dcb56 ), fails to build ( linking I'm guessing ). Fails to find a reference too glFlush ( error messages below )

Regression

  • removing the option -Dlegacy-x11=dri2 leads to successful build

  • Before commit 906dcb56 or reverting 906dcb56 starting from 69982e6f and git rm src/gallium/targets/osmesa/meson.build, build succeeds

Build configuration/script

I build 64bit manually ( for git bisect reasons ) from mesa repository rather than gentoo ebuild

When building 32bit, I do so just using gentoo emerge as I wasn't quite sure how to manually configure the build environment to 32bit. The ebuild for that is https://gitweb.gentoo.org/repo/gentoo.git/tree/media-libs/mesa/mesa-9999.ebuild?id=ae0f979e636e5c517ef46be2f6f6dc3c76959967
