There is another debian/ directory in the unpacked directory. clang++ --sysroot=/tmp/c/debian /tmp/c/a.cc works fine. If your `Delete the lib/ folder in it` steps means to delete lib/x86_64-linux-gnu, that compile error is expected. Even if the previous behavior does not error for the compile action, it will fail for the link action. If you want to make compile action work, you need lib/x86_64-linux-gnu. I think it is fairly reasonable for clang to assume that some directories need to exist for a sysroot to look less like a fake one. If you really want to make compile action work without an empty lib/x86_64-linux-gnu, perhaps delete some D.getVFS().exists in clang/lib/Driver/ToolChains/Linux.cpp:Linux::getMultiarchTriple. This is actually something I intend to do next. > > > On Tue, Mar 23, 2021 at 11:01 PM Fangrui Song <i...@maskray.me> wrote: >> >> On Tue, Mar 23, 2021 at 7:09 PM Nico Weber <tha...@chromium.org> wrote: >> > >> > Was this reviewed anywhere? >> >> No. This is a nice code cleanup.
