https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: net-misc/dhcdrop calls cpp directly. Discovered on: amd64 NOTE: As per QA policy, toolchain tools must not be called directly because they can cause issue in cross-compiling and because is not possible use a different CPP implementation (like clang-cpp). To reproduce, please use sys-devel/gcc-config[-native-symlinks], sys-devel/binutils-config[-native-symlinks] and set the CPP variable to x86_64-pc-linux-gnu-gcc -E.

Hm, i set up this in make.conf CC="x86_64-pc-linux-gnu-clang" CFLAGS="-O2 -pipe -frecord-gcc-switches -fno-diagnostics-color" CXXFLAGS="${CFLAGS}" LDFLAGS="-Wl,-O1 -Wl,--as-needed -fuse-ld=lld

(In reply to David Seifert from comment #4) > ago also overrides "CPP", and that's the likely culprit here. Ah, that slipped from my eyes, now it is obvious for me, that it uses C preprocessor from clang and C++ one - from gcc: > # ebuild dhcdrop-0.5.ebuild clean configure | grep preprocessor > checking how to run the C preprocessor... x86_64-pc-linux-gnu-clang -E > checking how to run the C++ preprocessor... x86_64-pc-linux-gnu-g++ -E
