there isn't such error with gcc 5.4.0
llvm-ar is called with hard-coded path build is continuing after creating symlink /usr/bin/llvm-ar there was similar problem with /usr/bin/clang /usr/bin/clang++

This should be resolved in the masked dev channel releases. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2dd4eba091de610ed6621df0b20daedc7c5c44c2 commit 2dd4eba091de610ed6621df0b20daedc7c5c44c2 Author: Mike Gilbert <floppym@gentoo.org> Date: Mon Jun 19 00:57:51 2017 -0400 www-client/chromium: wire-up cross-compile support Cross-compiling still does not work, but this gets us closer. - Build GN with the host (CBUILD) compiler, skip rebuild after bootstrap. - Add a toolchain definition for the host (CBUILD) compiler. - Set the host_toolchain option. - Set the target_cpu option based on the target arch (CHOST). The host_toolchain option is also set for native builds. This makes clang work without setting clang_base_path.

Created attachment 478304 [details] build.log.bz2 By the way, I'm not sure where ar="../../../../../../../../usr/bin/llvm-ar" comes from in your build. I tried with www-client/chromium-61.0.3141.7 (with Mike's change), and it worked. $ CC=clang CXX=clang++ emerge -1av chromium ... [27370/27372] python "../../build/toolchain/gcc_ar_wrapper.py" --output=obj/chrome/renderer/librenderer.a --ar="x86 _64-pc-linux-gnu-ar" rcsD @"obj/chrome/renderer/librenderer.a.rsp" Full log attached.
I will try later. Temperature in my room is between 27C and 29C.
