I have build qtwebengine with clang for quite a while now, but in updating it I get a build error. Reproducible: Always Steps to Reproduce: 1. Set up your system for CLang 2.

duplicate of 688218?
(In reply to Jonas Stein from comment #1) > duplicate of 688218? Unfortunately not. But I could retrace the bug successfully. It's missing -latomic to compile successfully. It is something like this bug: https://github.com/fish-shell/fish-shell/issues/5865 unfortunately I am at an impasse here. This bug also happens with the freshly updated clang 11.1.0 including all dependencies. Is there a problem compiling QtWebengine using clang, or is there just something that needs to be changed on my system? I have mostly compiled my system using clang, with just a few exceptions which simply do not compile, those are listed in the tracker as well. I would be glad to be of any assistance, the affected system is not work-critical and I can do some tests (like unstable software, patches etc.).
While digging I found this: https://llvm.googlesource.com/openmp/+/7bd70635240f69fcd4da4d98a4aca8aaa779dd11%5E%21/ Maybe this is somehow related?

Yep definately related... I just stumbled over the same issue and fixed it by modifying my portag environment, so I dont have to patch the ebuild or buildsystem. As Im only using clang selectively I have a /etc/portage/env/clang and copied it to /etc/portage/env/clang-atomic adding the Following line to it to modify the linker flags: LDFLAGS="${LDFLAGS} -latomic" Next I modified my existing /etc/portage/package.env/clang to use a different clang environment: dev-qt/qtwebengine clang-atomic definately not the cleanest way to fix it but a working workaround for the time beeing...

Thank you that's great news! Will definitely give it a try. Right now I am using a binpkg compiled on another system which fortunately shares the CPU flags.

I finally got around trying this. And it works! Now if this somehow could be put into the ebuild... Since I *AM* primarily using CLang, I took a quite similar route. I created a new env with just the LDFLAGS and it worked very fine. Thank you for this suggestion!
Please test with 5.15.2_p20211019.
(In reply to Andreas Sturmlechner from comment #7) > Please test with 5.15.2_p20211019. Sorry, it took a while for me to be able to test it. I tested it with the latest stable version, which is 5.15.2_p20211216. Worked like a charm, no more -latomic needed!
Thanks for checking back.
