• 4.6.3. Building a binary RPM from the spec file

Describe the issue:

When building the cello package from source RPM/spec file, the following error occurred:

    ...stripped...

Processing files: cello-debugsource-1.0-1.el9.x86_64
error: Empty %files file /root/rpmbuild/BUILD/cello-1.0/debugsourcefiles.list

RPM build errors:
    Empty %files file /root/rpmbuild/BUILD/cello-1.0/debugsourcefiles.list

Impact of this issue: The documentation consumer cannot reproduce the same outcome in the documentation.

Suggestions for improvement: Fix the cello spec file so that the binary package is buildable.
