qgle build fails on mavericks: "'glu.h' file not found"

[hal.dace@…]

QGle build fails with a missing header file. Main.log attached.

(Problem only visible since gle-graphics was so quickly and effectively fixed :-))

QGLE installs fine for me on Mavericks. Try first installing the mesa port, which provides glu.h. If that works we can add the dependency.

Okay this is extremely strange. I have installed mesa. I can see glu.h in /opt/local/include/GL. And qgle is still failing with exactly the same error after doing a port clean / port install for it.

[hal.dace@…]

Temporary workaround: sudo ln -s /opt/local/inclue/GL/glu.h /opt/local/include/glu.h

Builds and runs now -- I guess there should have been an extra -I to the compiler.

You shouldn't be getting glu.h from Mesa, but rather from the system OpenGL framework.

Per your log, your build includes the line -I/System/Library/Frameworks/OpenGL.framework/Headers. On my system:

$ ls -l /System/Library/Frameworks/OpenGL.framework/Headers/glu.h
-rw-r--r-- 1 root wheel 18745 Oct 24 09:52 /System/Library/Frameworks/OpenGL.framework/Headers/glu.h

(This appears to be identical to the glu.h that ships with XCode as part of MacOSX10.9.sdk, but it's not actually the same file -- I don't know if it was installed by XCode or shipped already on the system.)

Anyway, for me QGLE builds based on the above include, with no Mesa installed and no extra symlinking. Can you check and see if the OpenGL framework is installed on your system?

Thanks for the input John. It seems someone had forgotten to run xcode-select --install, and this is the first port that actually depended on it!

Sorry for the inconvenience and thanks again for the help. Feel free to close ticket as "user incompetence" :)

Very good. Yes, installing the Xcode command line tools is required.

It's possible #41783 may have helped this not be necessary, but for now we require it.
