RE: How to debug gtk application using gdb in Fedora

["Huang, FrankR" <FrankR Huang amd com>]

Yes. I want to debug into the gtk kernel. So I "enable-debug=yes".
I forget use LD_LIBRARY_PATH to load my compiled gtk library. After export this parameter, I can get into the gtk code.
I use ddd as my default gdb debug tool.

Thanks,
Frank

Make sure you've built your program with the "-g" flag, then type
something like:

$ gdb myapp
(gdb) break gtk_init
(gdb) run

See: http://www.gnu.org/software/gdb/documentation

There are also plenty of GUI wrappers over gdb, such as kdbg or even
ddd. You might find them easier to use.

valgrind is very useful for debugging memory errors.

You only need to do this if you want to debug the internals of gtk.
Even then, there are probably already debug versions of the libraries
in your package manager. Just build your program with -g.
