"failed on loading library A" is not very descriptive. How exactly
does it fail? g-ir-scanner uses the pkg-config files to link a
small program that introspects GOBject's and if you're library A
does not provide one or it's not passed to g-ir-scanner, then the
linking (or running the application) may fail.<br>
<br>
Side note: what does this library do? Would it be useful to include
upstream?<br>

<br>
g-ir-scanner builds the GObject-Introspection information so that
one can use the GStreamer GL library from other languages like
python or vala or javascript or whatever language there are binding
generators for.<br>
