I have done a little development using gtk 1.2.10 and have started
looking at upgrading. Someone installed gtk 2.0 on a networked disk I
have access to, so I tried building my application using that.
However, having hacked through the incompatibilities, when I run my app
it crashes with a segfault in gtk_init().
I've spent hours trawling the archives looking for an example of someone
else encountering and solving this, without success, so I hope someone
can help.
Eventually I wrote a noddy app to demonstrate the problem. The hard
bit is that as far as I'm concerned, gtk_init() is a black box. If the
prog dies in there, I have no clue as to why. The source might be out
there somewhere, but I don't know where.
So first I attach the back trace output from gdb, then the source of
my noddy app.
Any help would be much appreciated.
