So since nobody uses Motif anymore (
) I've embarked on yet another abortive attempt to learn the accursed gtk. I downloaded the "official" gtk "hello world" tutorial, and figured out what it takes to compile it, yes
this:
And what does it do when it runs? It segfaults! So yeah, that's everything that's wrong with gtk in a nutshell.
For anyone who's interested, a backtrace:
and the code (comments are mine, theirs are too verbose):
