It is known to work under 10.2.8 and 10.3 using Apple's gcc 3.3 compiler:
gcc (GCC) 3.3 20030304 (Apple Computer, Inc. build 1493)
Under 10.2.8 get the August 2003 gcc update (free at http://connect.apple.com). Under 10.3 get the Xcode Tools v1.0 (also free).
Python 2.3 is required. The Python that ships with 10.3 is fine. Under 10.2.8 use these commands to install Python as a framework:
./configure --enable-framework make make frameworkinstall
        The last command requires root privileges because the target directory is
        /Library/Frameworks/Python.framework/Versions/2.3. However,
        the installation does not interfere with the Python version that ships with
        10.2.8.
      
        It is also crucial to increase the stacksize
        before starting compilations, e.g.:
      
limit stacksize 8192k
        If the stacksize is too small
        the build might crash with internal compiler errors.
      
        Sometimes Apple's compiler exhibits a bug by printing an error like the following
        while compiling a boost::python::class_<your_type>
        template instantiation:
      
.../inheritance.hpp:44: error: cannot dynamic_cast `p' (of type `struct cctbx::boost_python::<unnamed>::add_pair* ') to type `void*' (source type is not polymorphic)
        We do not know a general workaround, but if the definition of your_type can be modified the following
        was found to work in all cases encountered so far:
      
struct your_type { // before defining any member data #if defined(__MACH__) && defined(__APPLE_CC__) && __APPLE_CC__ == 1493 bool dummy_; #endif // now your member data, e.g. double x; int j; // etc. };
