Created attachment 915570 [details] build.log and emerge --info Build fails with qt 6.8.1 media-video/mkvtoolnix-88.0 builds fine.
Same issue here. Have you tried the unstable version yet?
Created attachment 915857 [details, diff] 0001-Fix-build.patch This patch fixes it for me, anyone experiencing the issue can use it as a user patch until the bug is fixed.
Thanks for the user patch. Noting the same issue and patch in NixOS here: https://github.com/NixOS/nixpkgs/issues/348851 I think this only shows up with the "gui" use flag enabled, which might explain how it escaped into stable.
Fixed in upstream https://gitlab.com/mbunkus/mkvtoolnix/-/commit/fc83003f541ac690fe308c3f4ac36e62814a40db

Unstable version 88.0 compiles fine. I think this issue would be solved by stabilizing it. In the mean time version 89 is out. Best Regards, Georgi
