"AMD64 Fedora Rawhide Clang 3.x" buildbot worker is currently broken: https://buildbot.python.org/all/#/builders/169/builds/168
clang cannot build (statically linked) binary using UBSan:
$ ./configure --prefix '$(PWD)/target' CC=clang LD=clang CFLAGS=-fsanitize=undefined LDFLAGS=-fsanitize=undefined ... checking for gcc... clang checking whether the C compiler works... no configure: error: in `/home/buildbot/buildarea/3.x.cstratak-fedora-rawhide-x86_64.clang-ubsan/build': configure: error: C compiler cannot create executables See `config.log' for more details
I reproduced the issue on the worker. The issue comes from a version conflict between clang and compiler-rt packages:
compiler-rt-9.0.0-1.fc32.x86_64 uses /usr/lib64/clang/9.0.0/...
vs
clang-9.0.1-2.fc32.x86_64 uses /usr/lib64/clang/9.0.1/...
Charalampos created https://src.fedoraproject.org/rpms/compiler-rt/pull-request/10 to propose to update compiler-rt.
Sorry, something went wrong.
Charalampos downgraded clang to 10.0.0 to workaround the issue. The buildbot worker compiles the code succesfully again: https://buildbot.python.org/all/#/builders/169
I close the issue. The issue is now tracked in Fedora Rawhide anyway: https://src.fedoraproject.org/rpms/compiler-rt/pull-request/10
