Bug 2325398

I suppose to be able to generate proper appstream data from a Fedora repository one needs the rpmmd backend in the appstream-generator, but when I try to use it I just get:

   $ appstream-generator process test --verbose
   2024-11-12 08:45:40 - DEBUG: Using `optipng`: /usr/bin/optipng
   2024-11-12 08:45:40 - DEBUG: Using `ffprobe`: /usr/bin/ffprobe
   object.Exception@../src/asgen/engine.d(98): This appstream-generator was built without support for RPM-MD!
   ----------------
   ??:? asgen.engine.Engine asgen.engine.Engine.__ctor() [0x4659a9]
   ??:? _Dmain [0x405724]

Could you enable build of the rpmmd backend in Fedora, please?

This is with appstream-generator-0.9.1-5.fc41.x86_64

Note I tried to enable it and it results in a build failure:

../src/asgen/backends/rpmmd/rpmpkgindex.d(28): Error: unable to read module `xml`
../src/asgen/backends/rpmmd/rpmpkgindex.d(28):        Expected 'std/xml.d' or 'std/xml/package.d' in one of the following import paths:

The upstream version switched to a `dxml` here:
https://github.com/ximion/appstream-generator/commit/6a187884f39fa4caf9ef60b91feeba2f7dca184a
but it's not packaged either (maybe you can bundle that dependency?).

Reproducible: Always
