Any hints on how to reproduce this. I fail to do so!

[Comment 8 Sam James 2021-03-27 18:59:01 UTC]

Hmm. toralf, did you use any binpkgs from a slibtool build or anything like that?

/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: obj/ttmpeg2window.o: undefined reference to symbol 'glLoadIdentity'
/usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib64/libGL.so.1: error adding symbols: DSO missing from command line

This seems to imply libGL is broken...

No bin pkgs except the kernel bin package (this is new, I try to avoid kernel builds within tinderbox images)

[Comment 10 Petr Vaněk 2024-09-20 13:57:51 UTC]

I can reproduce the issue with following USE configuration:

dev-qt/qtopengl gles2-only
dev-qt/qtgui gles2-only egl
dev-qt/qtwidgets gles2-only

in which case the linker is executed with -lGLESv2, as you can see from the log, but /usr/lib64/libGLESv2.so does not provide glLoadIdentity. The gles2-only USE is set globally in the test env, see emerge-info.txt.
