Ok, unless I'm getting contradictory test results tomorrow, this looks like
a working procedure to build OSG 2.8 on AIX >= 5 with GCC.
1.) Point CMake to CURL- and probably other libraries like:
-D CURL_LIBRARY=/opt/freeware/lib/libcurl.a \
-D CURL_INCLUDE_DIR=/opt/freeware/include/curl
2.) Apparently the test for 'libm' fails on my AIX machine (I'm unable to
tell why), so call CMake with:
-D MATH_LIBRARY=/lib/libm.a
3.) I suspect there's an old workaround for AIX releases _before_ AIX 5.
Presumably the previous releases had their OpenGL headers stored in
/usr/include/OpenGL/. Therefore I had to modify a little compile time
switch:

#else
#include <GL/glu.h>
4.) Finally, almost all of the floating point types seem to be undefined on
AIX, at least with GCC - I decided to re-use some switches which are alredy
in place for the use on other commercial Unix systems:

inline float floorf(float value) { return

Even though my server has 8 CPU's, they only run at 200 MHz each, so I don't
expect the build to be ready before tomorrow :-)
Cheers,
Martin.
