Hi,
I got the latest stable release 3.2.1 rc2. I followed instructions in
generating xcode project for ios to generate the xcode project file. I am
building for iphoneSimulator. I am able to build OSG with Examples OFF, but if
I change it to Examples ON, it fails in osgViewerIPhone example.
It complains about OpenGL Framework, I checked my CMake configuartion, both
OPENGL_INCLUDE_DIR and OPENGL_gl_LIBRARY are set to
/System/Library/Frameworks/OpenGL.framework which does exist on my system.
Does the osgViewerIPhone example need OpenGL (I thought it needs OpenGLES), and
if so do I have to set any other variable in cmake. And if it does not require
it, how to remove it for the example.
I did search the forums before posting but did not find any instructions to
build the example alone, all instructions are for building OSG. Please let me
know if it is possible to build example alone after building OSG, and
instructions do it. Sorry for asking if I missed something, I am new to Mac and
ios development.
