Yes. pkgconfig files are only provided for modules that have libraries,
so you can link against these libraries.

gst-plugins-good only provides plugins, and you should check for the
presence of plugins at run-time in your app, not at compile time.

But is this actually a problem? This should not be fatal.

There is a .pc file for -good created, but only an -uninstalled.pc
file, which is for use in so-called 'uninstalled' gstreamer setups
(gst-uninstalled script). In this case it's needed to find the
directory of the good plugins. gst-rtsp-server and gst-plugins-bad need
that to locate these plugins for unit testing purposes in an
uninstalled setup.

Since this is all a bit confusing, this has been fixed at some point. I
believe recent versions of GStreamer (like 1.6.x or 1.7.x) no longer
perform these checks unless they detect that they're in an uninstalled
environment.

(To make matters worse, ubuntu actually ships a .pc file for good in
their packages which they shouldn't ship, because apparently they moved
some stuff from -bad into -good...)

 Cheers
