Subject: [bug#78022] [PATCH 8/8] gnu: kaldi-gstreamer-server: Fix build, cleanup tests.
Date: Thu, 24 Apr 2025 01:08:12 +0200

* gnu/packages/machine-learning.scm (kaldi-gstreamer-server):
  [origin]<snippet>: Remove test files.
  [arguments]<phases>: Migrate from GObject.MainLoop to GLib.MainLoop
  in 'build phase.  Adapt to the absence of test files.  Improve the
  wrap part of 'install phase.
  [inputs]: Add gstreamer, gst-plugins-base, gst-plugins-good, kaldi.
  They are necessary for proper install/wrapping.
