Answer 1

I finally solved the Problem. tojanfoe suggested in a comment the link http://www.hardcoded.net/devlogs/20120426 which turned out to not be helpful.

This is how i solved it:

1.a) Installation of GTK+ 2.x:

brew install gtk+

1.b) Installation of GTK+ 3.x:

You can install gtk+ 3.x via home brew too if you need that, but the 2.x version is enough for my purposes. The command would be:

brew install gtk+3

2.) But after the installation I had the problem, that cairo could not be found. So i solved it this way:

export PKG_CONFIG_PATH=/usr/local/Cellar/cairo/1.12.16/lib/pkgconfig/

3.) Then the compiler said it could not find the package 'xcb-shm', required by 'cairo'. This can be solved this way:

export PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig

After this command the compiler worked as expected.
