            Bug ID: 33823
           Summary: debugedit fails to detect sources if DWARF contains
                    relative, not absolute paths (empty
                    debugsourcefiles.list)
           Product: debugedit
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

  Target Milestone: ---

This is a summary from Matrix discussion.

On Fedora/RISCV some of ours builds fail as debugsourcefiles.list is empty.

RPM build errors:
error: Empty %files file
/builddir/build/BUILD/catch-3.10.0-build/Catch2-3.10.0/debugsourcefiles.list
    Empty %files file
/builddir/build/BUILD/catch-3.10.0-build/Catch2-3.10.0/debugsourcefiles.list


On riscv64 the file is completely empty, but that's not the case on x86_64 and
aarch64 (I didn't check all, but I expect the same). The file contains empty
directories, and the source package produces just ships empty directories.

Looking at catch package and two shared libraries the DWARF contains relative
paths instead of absolute (I compared to tcl package).

The following works: debugedit -l a.list libCatch2.so.3.10.0

What seems to cause the problem is these flags for debugedit:
-b /home/fedora/rpmbuild/BUILD/catch-3.10.0-build/Catch2-3.10.0 -d
/usr/src/debug/catch-3.10.0-1.fc43.riscv64

Other potentially affected packages:
error: Empty %files file
/builddir/build/BUILD/opensurge-0.6.1.2-build/opensurge-0.6.1.2/debugsourcefiles.list
error: Empty %files file
/builddir/build/BUILD/pgadmin4-9.3-build/pgadmin4-9.3/debugsourcefiles.list
error: Empty %files file
/builddir/build/BUILD/toolbox-0.3-build/toolbox-0.3/debugsourcefiles.list

This is not the final list, a quick scan of some build logs.

My theory is that debugedit doesn't handle relative paths in DWARF.
