Oh my gosh. I'm going to sound like an idiot here.

Take g_malloc0 () as an example.
Am I correct is understanding that functions like g_malloc0() no longer exist and there is a new
function in it's place for gtk+ 3? Or are thing done in a different way?


I looked at the section discussing converting your apps to gtk+3, but i didn't see anything about
new functions for malloc & friends.

I got scared and installed libgtk2.0-dev, and went back to my original makefile,  but I still can't compile.
I get all the same errors. This is scaring me, as it was fine for 6 months, and now it seems I can't even compile
with GTK2.

Can you provide more guidance? Is there a cross-reference of 2 versus 3 or something.
I'm completely bamboozled.

Dave

Right, usually though, you dont care about the linker error.

... until you've fixed all the compiler warnings mentioning
unresolved symbols...

You will be more interested in the compiler warnings because
they will tell you exactly where in your source code that you
are mentioning missing symbols such as 'g_threads_got_initialized'

... while you go ahead and modify
 your source to use new and
updated apis, after fixing those compiler warnings... you
should not get the linker error anymore.
