Crash when running on Mac

[kaspernj]

port install gtk3 brew install gobject-introspection

Then in Ruby:

require "gir_ffi-gtk3"

Got the following:

Same error with Gtk2. I am willing to give access to my machine by using VNC or something else, if that can help.

Hi Kasper,

For some reason gobject-introspection cannot find the introspection data for Gtk. I'm not too familliar with these package managers, but perhaps using 'port' to install gtk3, and then 'brew' to install gobject-introspection has something to do with this. Can you try installing both with the same package manager?

[kaspernj]

For some reason, it looks like the "gobject-introspection" from port is Python-specific and the "gtk+3"-package from brew compiles it with introspection disabled (dont really understand why, but the configure-files are specifically set to disable it).

Can you give me a hint of which files it is looking for? It may be a problem with linking (brew works by making a custom-path install and then linking files).

[mvz]

It's looking for a file called Gtk-3.0.typelib, which on GNU/Linux is located in /usr/lib/girepository-1.0/.

[kaspernj]

I got it working! Had to hack it a bit with various symlinks though, because "port" installs in "/opt/local/lib". It is possible to make it look in "/opt/local/lib" to make it compatible with "port" by default?

Here are the commands I used:

sudo port install gtk3 sudo port install gobject-introspection

cd /usr/lib sudo ln -s /opt/local/lib/girepository-1.0 sudo ln -s /opt/local/lib/libgirepository-1.0.dylib sudo ln -s /opt/local/lib/libgobject-2.0.dylib

Be aware the "brew" corrupts the install, so you will have to uninstall various packages from "brew" like "gtk+3", "gobject-introspection", "atk" and so on.

[mvz]

Is the first ln -s still necessary now that you use port for both gtk3 and gobject-introspection?

Also, how was Ruby installed? The ffi gem should be able to find libgirepository-1.0.dylib and libgobject-2.0.dylib by itself, without the softlinks.
