Example rpm build cello fails with request for debugsourcefiles.list

[huitema]

I am trying to learn how to produce RPM packages. I am following the steps in the guide, but I am getting an error when trying

rpmbuild --rebuild ~/rpmbuild/SRPMS/cello-1.0-1.fc28.src.rpm

The error is:

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

I assume I something did wrong, but I am getting the cello "tar*.gz" package from the URL in the documentation, and I have verified that the cello.spec file matches the doc as well. So either there is something unsaid in the doc, or there is another issue.

The full output of the --rebuild command is:

This seems to me as rpm issue. It used to work. And it does not work on Fedora 28 now. I reported this as https://bugzilla.redhat.com/show_bug.cgi?id=1583329

[xsuchy]

I updated both documentation and the tar ball. So the Makefile now generate debug information and rpmbuild proceed without errors.

I confirm that this works, thanks. I had to read a little between the lines in the documentation. It seems that the key is to use the "-g" option in gcc/g++. Is that correct?
