I'm trying to compile native LLVM support into American Fuzzy Lop. Unfortunately debuginfo generation fails with: + /usr/lib/rpm/find-debuginfo.sh --strict-build-id -m --run-dwz --dwz-low-mem-die-limit 10000000 --dwz-max-die-limit 110000000 /home/rjones/d/fedora/american-fuzzy-lop/master/afl-2.41b extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/bin/afl-tmin extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/bin/afl-analyze extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/bin/afl-gotcpu extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/bin/afl-showmap extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/bin/afl-clang-fast extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/bin/afl-gcc extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/bin/afl-fuzz extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/lib/afl/afl-llvm-pass.so extracting debug info from /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/lib/afl/afl-llvm-rt-64.o *** ERROR: No build ID note found in /home/rjones/rpmbuild/BUILDROOT/american-fuzzy-lop-2.41b-2.fc27.x86_64/usr/lib/afl/afl-llvm-rt-64.o error: Bad exit status from /var/tmp/rpm-tmp.lnlcV6 (%install) Notice that the file that fails is a C object file (not a shared library), and C object files apparently don't have build IDs. I can't work out how to add a build ID. All the workarounds involve use of the linker (eg. -Wl,-B,...) but that doesn't help as the linker is never invoked on object files. While it's a bit odd that LLVM is using an object file instead of a shared library, I guess it does that for ... reasons. So is there a way to get find-debuginfo.sh to tolerate these files? (A cursory look at find-debuginfo.sh doesn't show anything obvious, but I could be missing something). Or maybe there's another way to solve this?
