Description Florian Weimer 2021-06-23 06:37:25 UTC

This issue will start impacting cmake in Red Hat Enterprise Linux 9 once we switch to glibc 2.34.

You can test a fix before glibc 2.34 is merged using this command:

koji -p stream build --scratch c9s-build-side-102-stack-gate git+https://gitlab.com/redhat/centos-stream/rpms/cmake#origin/c9s

A build-time test fails:

The test probably should include <gnu/lib-names.h> and use the LIBDL_SO macro defined there.
