My experience with Mac development has not quite so smooth. Getting cmake to
build was a battle and beyond the scope of this thread. OSG itself has some
appearant rough edges with OSG and X11 integration. I am working with
OpenSceneGraph-2.6.0, so I'm lagging a bit behind the most recent developments.
I needed to add a few lines from a "future" version of CMakeLists.txt to find
some X11 include files in order to build examples/osgviewerQT...
IF(APPLE)
FIND_LIBRARY(CARBON_LIBRARY Carbon)
FIND_LIBRARY(COCOA_LIBRARY Cocoa)
# Added these...
# X11 on Apple requires X11 library (but not OpenGL linking hack) on Leopard
# Find GL/glx.h
IF(EXISTS ${CMAKE_OSX_SYSROOT}/usr/X11/include/GL/glx.h)
SET(OPENGL_INCLUDE_DIR /usr/X11/include)
ELSEIF(EXISTS ${CMAKE_OSX_SYSROOT}/usr/X11R6/include/GL/glx.h)
SET(OPENGL_INCLUDE_DIR /usr/X11R6/include)
ENDIF(EXISTS ${CMAKE_OSX_SYSROOT}/usr/X11/include/GL/glx.h)
# ...done.
ENDIF(APPLE)
Another problem that took me a while to run down is a result of the screwy
DISPLAY variable on MAC which is typically something like
"/tmp/launch-pDgQFH/:0". This confounds GraphicsContext::ScreenIdentifier which
ultimately sets screenNum to -1 causing a failure later on. The demo
examples/osgthirdpersonview cow.osg exhibits this behavior.
A proble I have yet to run down is a "BadWindow (invalid Window parameter) error
with the demo examples/osgviewerQT with runh with "cow.osg --QOSGWidget".
My Mac is running OS X 10.5.2 and Xquartz 2.2.3 w/ NVIDEA GeForce 7300 GT.
