--- Comment #15 from Tobias Burnus <burnus at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #13) > I wonder how it works for Tobias then. Bootstrap * works on x86_64 with Ubuntu 20.04.5 LTS (focal) with glibc 2.31-0ubuntu9.9 * fails on ppc64le with Ubuntu 18.04.3 LTS (bionic) with glibc 2.27-3ubuntu1 I have now done some debugging. The reason it works on x86-64 is that I have there in the $BUILD directory: gcc/include-fixed/bits -> x86_64-linux-gnu/bits That matches: /usr/include/bits -> x86_64-linux-gnu/bits dpkg -S find * the symbolic link in package libc6-dev-i386 * the real 'bits' directory in package libc6-dev:amd64 On PowerPC, I see /usr/include/powerpc64le-linux-gnu/bits but no associated /usr/include/bits symbolic link. (The existing directory is in package libc6-dev:ppc64el) * * * Before finding this, I wondered whether --enable-multiarch makes a difference, but it doesn't.
