Hi Ago,

I can reproduce the issue now with command line:

  CC=clang CXX=clang++ LD=ld.lld LDFLAGS=-fuse-ld=lld ebuild redshift-1.12-r3.ebuild manifest clean compile

and even with plain

  CC=clang ebuild redshift-1.12-r3.ebuild manifest clean compile

I have taken the issue upstream just now.

What do you suggest we do in the ebuild while we wait for a new release with  fix?

  a) Detect clang and extend LDFLAGS?

  b) Detect and deny use with clang?

  c) Unconditionally extend LDFLAGS?

  d) ...?

Is there a blueprint for issues like that somewhere?

Thanks and best, Sebastian
