Vala + Gtk doesn't work in mac os x

Question

I installed Vala via homebrew and compiled a normal hello world app in osx 10.9.3. This is the error-message report:

How to get Gtk Framework to work? Any help highly appreciated.

Answer 1

The Gtk+ libaries you have downloaded are compiled for 32-bit processors, but you are attempting to compile for 64-bit. You can:

1. Pass -X -m32 to build 32-bit binaries.
2. Get 64-bit binaries of Gtk+. This is probably the better choice.
