Linux Qt: Boxes demo gluPerspective

I was compiling the Linux Qt Demo: Boxes for Qt4.8.1 and ran into these errors. Here’s how I fixed them:

/home/mfang/dev/QtSDK/Demos/4.7/boxes/qtbox.cpp:329: error: ‘gluPerspective’ was not declared in this scope

In qtbox.cpp and scene.cpp add:

#include “GL/glu.h”

Explanation:

According to the Qt SDK reports, they removed the GL/glu.h header file so you need to add the Gl/glue.h header file to qtbox.cpp and scene.cpp.

Error:

/home/mfang/dev/QtSDK/Demos/4.7/boxes/scene.cpp:926: undefined reference to `gluPerspective’

Fix in boxes.pro add:

LIBS += -L/usr/local/lib -lGLU

These fixed helped get the Boxes demo project to compile but it didn’t run for me as it seg faulted. Hopefully you’ll have better luck.
