[gtk-osx-users] Bundling, Mountain Lion, and X11 freetype library

[Kristaps Dzonsons <kristaps bsd lv>]

Hi folks,

Short story: when building GTK+3 applications on OSX with a fresh 
install of jhbuild, the system freetype (X11) library is listed as 
dependencies in the generated library.  Unfortunately, deploying this 
bundle to other "post-X11" Mac systems (starting with Mountain Lion, I 
guess?) doesn't work without end-user installation of xquartz.

Solutions?

Longer story...

Steps: check out the current version of gtk-osx-build-setup.sh, 
bootstrap and build GTK+3 via the standard jhbuild instructions.  Build 
a utility that uses MAC_INTEGRATION (i.e., GtkosxApplication) within the 
jhbuild shell.  All's normal here.  Application works fine when invoked 
from the command line.  (And bundles fine too for the local machine.)

Looking at the executable (shown as "theapp", with paths shortened and 
output truncated to fit in a message window):

% otool -L theapp
theapp:
        ...gtk/lib/libgtkmacintegration.2.dylib
        ...gtk/lib/libgtk-3.0.dylib
        ...gtk/lib/libgdk-3.0.dylib
        ...gtk/lib/libatk-1.0.0.dylib
        ...gtk/lib/libgio-2.0.0.dylib
        ...gtk/lib/libpangocairo-1.0.0.dylib
        ...gtk/lib/libgdk_pixbuf-2.0.0.dylib
        ...gtk/lib/libcairo-gobject.2.dylib
        ...gtk/lib/libpango-1.0.0.dylib
        ...gtk/lib/libcairo.2.dylib
        ...gtk/lib/libgobject-2.0.0.dylib
        ...gtk/lib/libglib-2.0.0.dylib
        ...gtk/lib/libintl.8.dylib
        /usr/lib/libSystem.B.dylib

Looks good so far.  Unfortunately... (again with paths shortened for 
fitting in this mail)

        ...gtk/lib/libffi.6.dylib
        ...gtk/lib/libglib-2.0.0.dylib

        ...frms/Foundation.framework/Versions/C/Foundation
        ...frms/AppKit.framework/Versions/C/AppKit

Notice the "libfreetype" inclusion.  This occurs in many of the 
dependent libraries of theapp.  (libgtk, libpangocairo, etc.)  When 
bundling with this dependency, not only does gtk-mac-bundler raise 
errors, but the end-users are asked to install xquartz.

I was able to recompile libpangocairo not to use X11 by jhbuilding the 
freetype module beforehand (I guess it picks up the GTK-installed 
freetype before the system one, in that case), but obviously all modules 
would need to be similarly recompiled.  I notice that libpangocairo 
depends on the freetype meta-module.

Is there a way to rebuild the GTK+3 installation, playing nicely with 
jhbuild, to pull in the compiled freetype instead of the system X11 one?

Thank,
