anyone know anything about GTK2 to GTK3?
I'm hacking away again, I'm trying to update this terminal written in gtk2 to get it up to gtk3 ( so I can use it again on this distro I'm running now)
It is late here and figued I'd try to get a good few hours of production in on this, and this is what I ended up with.
(Linux OS btw )
(forgive the mess of code, I have not cleaned it up at all. saving that for last)
I got it to compile, haivng to remove the key codes, copy, paste, until I get them figured out, but when I ran it
Code:
userx@slackwhere:~/Downloads/tinyterm-0.5.8
$ ./a.out
(a.out:28415): Gtk-ERROR **: GTK+ 2.x symbols detected. Using GTK+ 2.x
and GTK+ 3 in the same process is not supported
Trace/breakpoint trap
Code:
gcc `pkg-config --cflags gtk+-3.0` `pkg-config --libs gtk+-3.0 vte` tinyterm.c
this is my first time playing with GTK so anyone know what do I need to do to get that gtk2 symbols out of there?
(shot in the dark)
Anyone got a lead on keycodes? It does not like the defines in the header, it has no idea what they are.
I think by what little bit I looked at as of yet,I might end up having to rewrite that whole part of it.
