--- Comment #2 from stli@linux.ibm.com --- I've adjusted the spec file according to your comments. But I can't use make_install as it would setup DESTDIR instead of install_root.
You'll find the current spec-file here: https://pagure.io/fork/stliibm/libdfp/blob/stli-20190904/f/libdfp.spec I've also created a pull-request: https://pagure.io/libdfp/pull-request/1
I've also performed some scratch builds for ppc64le and s390x on: -F30: https://koji.fedoraproject.org/koji/taskinfo?taskID=37456479 -F31: https://koji.fedoraproject.org/koji/taskinfo?taskID=37456559 -epel8: https://koji.fedoraproject.org/koji/taskinfo?taskID=37456581
They are all green despite of epel8 on s390x where I've got test-fails: FAIL: test-cast-to-overflow FAIL: test-cast-to-underflow => These tests fails due to a missing patch in gcc (see https://github.com/libdfp/libdfp/issues/71#issuecomment-420614177). The patch was backported to gcc 8.3.
According to the logs for the epel8 build, gcc-8.2.1-3.5.el8.src.rpm was used. Will epel8 use a newer gcc-8.3.* as soon as such a newer version is available in RHEL 8?
