Detailed Description

Native debug symbols are already stored below /usr/lib/debug. This change modifies mingw-find-debuginfo.sh, part of mingw-filesystem, to do the same.

Benefit to Fedora

Besides alignment with debuginfo symbols of native packages, this avoids an easy to hit issue for mingw packagers where .debug files end up in the main package, i.e.

%files -n mingw64-libfoo

%{mingw64_libdir}/plugindir/

where %{mingw64_libdir}/plugindir/ contains both say libfooplugin.dll as well as libfooplugin.dll.debug.

Scope

• Proposal owners:

mingw-find-debuginfo.sh will be updated to store debug symbols below /usr/lib/debug, as follows:

Store debug files below /usr/lib/debug

• Other developers:

%excludes of *.debug files can be dropped from spec files.

• Release engineering: Impact check [1]
• Release engineering: Mass rebuild requested
• Policies and guidelines: No policies need to be changed
