Those functions are for display lists, which aren't available in OpenGL ES.
I've followed the instructions in README.txt, but I get thousands of the above
errors. I also have added the frameworks: QuartzCore, Foundation, OpenGLES,
UIKit, CoreGraphics as they were added from my ccmake.
In my ccmake configuration there wasn't an option to disable OSG_GLU_AVAILABLE
as per the instructions.
Also, I downloaded OpenFrameworks Git to get the FREETYPE libraries and set
them up like this (with absolute paths, but i've truncated here):
FREETYPE_INCLUDE_DIR_freetype2: openFrameworks/libs/freetype/include/freetype2
FREETYPE_INCLUDE_DIR: openFrameworks/libs/freetype/include/freetype2
FREETYPE_LIBRARY: openFrameworks/libs/freetype/lib/iphone/freetype-iphone.a
I'm not the OSG iPhone expert, but I don't think those settings are your
problem. It sounds like you've got CMake set up to compile for regular
OpenGL and not OpenGL ES. I believe you need to turn off
OSG_GL1_AVAILABLE, OSG_GL2_AVAILABLE, and OSG_GL3_AVAILABLE, and turn on
OSG_GLES1_AVAILABLE and/or OSG_GLES2_AVAILABLE (depending on which model
iPhone you're targeting).
If you've got these settings correct, then something else is going on,
and you'll have to wait for more qualified help :-)
