Dear all,

Building unix/geoX(.app) on my mac required only minor changes. The
changes work on both my linux machine and my mac. I describe the steps
I took, in case other students ask you for help.

In case it matters, I use Mac OS X 10.7.5, kernel version 11.4.2, and
gcc version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.1.00).

I built and installed qt4, configuring it with the following command.

./configure\
-opensource\
-confirm-license\
-prefix /usr/local/qt485\
-prefix-install\
-debug-and-release\
-developer-build\
-graphicssystem opengl\
-silent

Following my nose, I ran "qmake -recursive" and "make" in the geoX
source tree, tweaking things until the compilation went through. Some
of Apple's OpenGL headers and libraries have different names than geoX
expects.

• I created ./viewers/widgets/glu.h containing

#ifndef __APPLE__
#include <GL/glu.h>
#else
#include <OpenGL/glu.h>
#endif

and changed GeoXGLWidget.h and GeoXGLWidget3D.h to include "glu.h"
rather than <GL/glu.h>.

• I removed the OpenGL libraries in unix.pro and added a line "QT += opengl":

--- a/unix/unix.pro
+++ b/unix/unix.pro
@@ -44,9 +44,5 @@ LIBS += \

+QT += opengl

Best,
