I think part of the problem you are seeing is that OS X 10.6 defaults to a 64 bit build where as OS X 10.5 defaults to a 32 bit build. So in order for you to build a 32 bit binary on OS X 10.6 you need to specifically set "CMAKE_OSX_ARCHITECTURES" to i386 when you want to build a 32 bit i386 executable on OS X 10.6. You can generate a 32 bit PPC executable by setting CMAKE_OSX_ARCHITECTURES=ppc. The set the CMAKE_BUILD_TYPE to "Debug" and that should get you a 32 bit PPC executable that has Debugging symbols. _________________________________________________________ Mike Jackson mike.jack...@bluequartz.net
