[lazarus] GTK2: undefined references

[Andrew Johnson]

What I understood from Mattias is, that you need to use pkg-config to
get the proper libs to link and to make sure the ld-linux is first in
the list(which is accomplished by the gtk2 packages), as glib2 bites it.
So since fpc auto makes it last in the list normal makes don't work. If
you wish to try the lazarus IDE in gtk2 this can be done in lazarus by
installing the gtk2 package and the gtk2 interface package,(but not
recompiling the ide when prompted), then compile lazarus for the gtk2
interface with packages. Otherwise you can create a shell script which
does the same special linking for you(this is what I do).

If you just wish to run a test app you need to add the gtk2 package, and
the gtk2 interface package to the projects depends. Then you can do it
as usual. I believe Mattias added explicit instructions for this to the
interfaces/gtk2/README
