Description Petr Pisar 2020-01-21 14:00:06 UTC

slurm-19.05.5-1.fc32 fails to build in F32:

libtool: link: gcc -shared  -fPIC -DPIC  .libs/dist_tasks.o .libs/job_test.o .libs/select_cons_tres.o   -Wl,-z,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -O2 -g -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -pthread -Wl,-z -Wl,relro -Wl,--as-needed -Wl,-z -Wl,now -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-z -Wl,lazy   -pthread -Wl,-soname -Wl,select_cons_tres.so -o .libs/select_cons_tres.so

A difference between passing and failing build root is at <https://koschei.fedoraproject.org/build/7736161>. This is probably triggered with an upgrade of gcc from 9.2.1-1.fc32.3 to 10.0.1-0.3.fc32.

Comment 1 Philip Kovacs 2020-01-22 17:02:03 UTC

It's the new gcc 10 default of -fno-common.  I pushed and tested a workaround fix to master (using -fcommon) and filed a bug upstream for them to add the needed externs in their headers.  Closing.
