Simon,   Maybe there is something wrong with my system, since I see:

It's possible that your system has only the run-time and the headers are only in the SDK inside Xcode. In that case the change Duncan made should work, because the compilers are aware of the SDK and thus will find it even if it's not in /System.

Cheers,
Simon

Duncan:  I'll try the new patched version of rgl once it is available on R Forge.

Thanks to you both!

Roger

Duncan,

I didn't look at the code, but the approach seems strange - if you use something from the GLKit framework then the include should be

#include <GLKit/GLKMathUtils.h>

without specifying -I... You should never have the need to include the "Headers" directory directly (other than cases where the framework contains non-framework headers like R does) since frameworks are searched automatically when referenced.


@Roger: on 10.9.2 (darwin 13.1.0 - which matches your build) I see
$ ls -l /System/Library/Frameworks/GLKit.framework/Headers/
total 16
-rw-r--r--  1 root  wheel   7327 Apr 11 05:49 GLKBaseEffect.h
-rw-r--r--  1 root  wheel   1435 Apr 11 05:49 GLKEffectProperty.h
[...]
-rw-r--r--  1 root  wheel   1224 Apr 11 05:49 GLKMathUtils.h
[...]

Cheers,
Simon

I do have a GLKit.framework  but there is no Headers subdir ...  

What OSX version is that?  There were warnings about deprecated code in
rgl, so I switched to using GLKMathUtils, but apparently the configure
script isn't quite right.
