[Openmcl-devel] cl-cffi-gtx on OS X

[Christopher Stacy]

I am trying to load  CL-CFFI-GTX (http://www.crategus.com/index.php/projekte/ <http://www.crategus.com/index.php/projekte/>)
on OS X Yosemite on CCL 1.10-r16196.

First problem is that CFFI isn't finding the libraries.

Unable to load any of the alternatives:
   ("libglib-2.0.0.dylib" "libglib-2.0.dylib")
   [Condition of type CFFI:LOAD-FOREIGN-LIBRARY-ERROR]

I installed GTK using Homebrew and I can see the links to all the GTK libraries.
In particular:

/usr/local/lib/libglib-2.0.0.dylib -> ../Cellar/glib/2.42.1/lib/libglib-2.0.0.dylib

Not sure why it isn't being found.

My environment has no DYLD_LIBRARY_PATH set, which I believe is normal.

I tried pushing /usr/local/lib onto cffi:*foreign-library-directories*
but it still didn’t find it.

I even went so far as to make a symbolic link from /usr/lib

/usr/lib$ otool -L libglib-2.0.0.dylib 
libglib-2.0.0.dylib:
	/usr/local/lib/libglib-2.0.0.dylib (compatibility version 4201.0.0, current version 4201.1.0)
	/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
	/usr/local/opt/gettext/lib/libintl.8.dylib (compatibility version 10.0.0, current version 10.2.0)
	/System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 157.0.0)
	/System/Library/Frameworks/Foundation.framework/Versions/C/Foundation (compatibility version 300.0.0, current version 1151.16.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1151.16.0)
	/System/Library/Frameworks/CoreServices.framework/Versions/A/CoreServices (compatibility version 1.0.0, current version 62.0.0)


but still no joy:

CL-USER> (probe-file "/usr/lib/libglib-2.0.0.dylib")
#P"/usr/local/Cellar/glib/2.42.1/lib/libglib-2.0.0.dylib"
CL-USER> (asdf:load-system 'cl-cffi-gtk)
; Evaluation aborted on #<CFFI:LOAD-FOREIGN-LIBRARY-ERROR #xCE632BE>.

Any idea what I’m doing wrong?
(Probably something dumb…)
