I'm using GN and Ninja to build a Chromium project but encountered the following error:
$ ninja -C out/Release/
...
...
../../third_party/llvm-build/Release+Asserts/bin/clang++: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by ~/client/third_party/llvm-build/Release+Asserts/bin/../lib/libstdc++.so.6)
The reason being it uses the prebuilt clang tooling that comes with the project, however I'm on CentOS 7 and the pinned version of glibc is GLIBC_2.17, and I do have a separate clang tooling which doesn't require GLIBC_2.18, the question is how do I configure GN or ninja to not use the prebuilt clang that comes with the project?
Check out this page, after gn gen command, one can override the llvm toolchain location by editing the clang_base_path parameter in the args.gn file.
