https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: app-crypt/qca-2.3.1 fails to compile with compiler-rt. Discovered on: amd64 (internal ref: tinderbox)
Created attachment 663043 [details] build.log build log and emerge --info
Possible context of error(s): /usr/lib/gcc/x86_64-pc-linux-gnu/10.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: tools/mozcerts/CMakeFiles/mozcerts-qt5.dir/main.cpp.o: undefined reference to symbol '_Unwind_Resume@@GCC_3.0' clang-10: error: linker command failed with exit code 1 (use -v to see invocation)
Patches welcome, I'm not going to invest time in this.
I'm unconvinced this isn't a local issue. Re-open when you reproduce it, and add emerge history when you do.
