Created attachment 546476 [details] emerge --info dev-libs/libgcrypt When compiling =dev-libs/libgcrypt-1.8.3 with clang I get the following error: /var/tmp/portage/dev-libs/libgcrypt-1.8.3/work/libgcrypt-1.8.3/random/jitterentropy-base.c:60:4: error: "The CPU Jitter random number generator must not be compiled with optimizations. See documentation. Use the compiler switch -O0 for compiling jitterentropy-base.c." I found a related NixOS bug, with a patch but it doesn’t fix the issue: https://github.com/NixOS/nixpkgs/issues/27906#issuecomment-320305941
Okay, it works with o-flag-munging, so I’ll mark it as resolved. Sorry for the noise. Anyway could we have a mention of clang in the USE flag description? I wasn’t sure that this was what I wanted until trying to build it and waiting.
