GTK2 code was historically kept around to keep the electron build working. But as of Nov 26, 2017, electron now uses GTK3 [1], so it should now be safe to remove all of the old GTK2-only code.

# Linux Debugging GTK
|
|
|
|
## Making warnings fatal
|
|
|
|
See
|
|
[Running GLib Applications](http://developer.gnome.org/glib/stable/glib-running.html)
|
|
for notes on how to make GTK warnings fatal.
|
|
|
|
## Using GTK Debug packages
|
|
|
|
sudo apt-get install libgtk-3-0-dbg
|
|
|
|
Make sure that you're building a binary that matches your architecture (e.g.
|
|
64-bit on a 64-bit machine), and there you go.
|
|
|
|
### Source
|
|
|
|
You'll likely want to get the source for gtk too so that you can step through
|
|
it. You can tell gdb that you've downloaded the source to your system's GTK by
|
|
doing:
|
|
|
|
```shell
|
|
$ cd /my/dir
|
|
$ apt-get source libgtk-3-0
|
|
$ gdb ...
|
|
(gdb) set substitute-path /build/buildd /my/dir
|
|
```
|
|
|
|
NOTE: I tried debugging pango in a similar manner, but for some reason gdb
|
|
didn't pick up the symbols from the symbols from the `-dbg` package. I ended up
|
|
building from source and setting my `LD_LIBRARY_PATH`.
|
|
|
|
See [linux_building_debug_gtk.md](linux_building_debug_gtk.md) for more on how
|
|
to build your own debug version of GTK.
|
|
|
|
## Parasite
|
|
|
|
http://chipx86.github.com/gtkparasite/ is great. Go check out the site for more
|
|
about it.
|
|
|
|
Install it with
|
|
|
|
sudo apt-get install gtkparasite
|
|
|
|
And then run Chrome with
|
|
|
|
GTK_MODULES=gtkparasite ./out/Debug/chrome
|
|
|
|
## GDK_DEBUG
|
|
|
|
Use `GDK_DEBUG=nograbs` to run GTK+ without grabs. This is useful for gdb
|
|
sessions.
