The attachments contain build output and whatnot, build output looks pretty much like this upstream bug though: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3875 which was marked a duplicate of https://gitlab.freedesktop.org/mesa/mesa/-/issues/3873 The latter bug mentions it should be fixed with meson >=0.56.0 but I'm running 0.56.2 as far as I can see. To me it looks like either the next release candidate would fix this, or that something about the meson call needs changing (i.e. -Dmicrosoft-clc=disable), but I don't have time to look further into this right now. This is perfectly reproducible on my current setup, though at the moment I'm still running world updates with mesa-21.0.0 masked (which compiles just fine) after the display-manager-init change, I'll report back after all my updates are done to confirm whether this is still the case with updated world. Reproducible: Always Steps to Reproduce: 1. emerge media-libs/mesa-21.0.0_rc5 with use-flags from Additional Information Actual Results: Compilation aborts in configure phase because it cannot find clang (which is installed though).

Created attachment 688299 [details] relevant output of emerge -DNu world (which tried updating mesa)
Created attachment 688371 [details] updated emerge output for mesa only, with current @world Seems after the @world update it's still the same. Next I'll try adding the mentioned option to a local version of the ebuild to see if the upstream issues were right about how to fix this.
When I add `-Dmicrosoft-clc=disabled` (without backticks) to emesonargs¹ (after line 512 for example) then it passes the step that failed previously² and yields the error from https://bugs.gentoo.org/771759³. ¹: https://github.com/gentoo-mirror/gentoo/blob/3985616c588905aa2fadd4dff0c1b715b97bb629/media-libs/mesa/mesa-21.0.0_rc5.ebuild#L495-L515 ²: Dependency clang (modules: clangBasic, clangCodeGen, clangDriver, clangFrontend, clangFrontendTool, clangHandleCXX, clangHandleLLVM) skipped: feature microsoft-clc disabled ³: ../mesa-21.0.0-rc5/meson.build:436:4: ERROR: Problem encountered: EGL requires dri
IUSE=egl is gone. EGL is now alwasy enabled. I think this is fixed?
