In boost/libs/python/src/converter/registry.cpp, I found:
#if defined(__APPLE__) && defined(__MACH__) && defined(__GNUC__) \ && __GNUC__ == 3 && __GNUC_MINOR__ <= 4 && !defined(__APPLE_CC__) # define BOOST_PYTHON_CONVERTER_REGISTRY_APPLE_MACH_WORKAROUND #endif
I have no idea what defining that big long symbol does, but I think that the conditionals are incorrect. <http://developer.apple.com/technotes/tn2002/tn2071.html> says: __APPLE__ This macro is defined in any Apple computer. __MACH__ This macro is defined if Mach system calls are supported. __APPLE_CC__ This macro is set to an integer that represents the version number of the compiler. This lets you distinguish, for example, between compilers based on the same version of GCC, but with different bug fixes or features. Larger values denote later compilers. I can't see any case where __APPLE__ and __GNUC__ are defined, and __APPLE_CC__ is not defined. Metrowerks? ==> No __GNUC__ Not on a Mac? ==> No __APPLE__ __APPLE_CC__ was defined for Apple-released versions of GCC, starting with 2.95.2 (so says Chris Espinosa at Apple). More historical info is at <http://developer.apple.com/releasenotes/DeveloperTools/GCC2.html> So, I think that that whole #if expression always evaluates to "false". -- -- Marshall Marshall Clow Idio Software <mailto:marshall@idio.com> It is by caffeine alone I set my mind in motion.
