# 2000/06/14: Ed Santiago - Original version
# 2003/09/12: Ryan Boller - Modified for multiple platforms/languages
# 2004/03/18: Ryan Boller - Modified for OS auto-detect, Mac compatibility
# 2009/11/25: Ryan Boller - Added compiler flags for 64-bit Mac platform

# NOTE: If using MS Windows, this Makefile is only useful for gcc/cygwin builds.
#    Also note that these builds will not be compatible with IDL 6.0+, as
#    they are based on Microsoft Visual C++ 7.0.  If you need to build for
#    IDL 6.0+, use the "make_CXFORM_MSVC.bat" file.  You will also need
#    to have either MSVC++ 7.0 (not free) or MSVC++ Toolkit 2003 (free)
#    installed.


# NOTE: User needs to modify appropriate directory for system-specific location of IDL
