Sage 64 bit OSX 64 bit build notes
fortran-20071120.p3
gfortran: need 64 bit run time and compiler - special build on bsd in gfortran-4.2.2/dist
copy ~/gfortran-4.2.2/dist into $SAGE_LOCAL
extend DYLD_LIBRARY_PATH=local/lib/x86_64/:$DYLD_LIBRARY_PATH
- Add "-m64" to sage_fortran options, link x86_64 libgfortran.dylib
rm $SAGE_LOCAL/lib/libssp*, $SAGE_LOCAL/lib/libssp*, $SAGE_LOCAL/lib/libgfortran.2*
ToDo
gmp-4.2.1.p12
Sage 3.0.2.alpha1 has upgrade to gmp 4.2.2, so use ABI=64 to make it compiled for the 64 bit mode.
_ctypes.so for 64 bit OSX
Building the _ctypes.so extension fails.
- replace libffi with latest [3.0.5 on OSX 10.5] to build _ctypes.so - this causes trouble due to missing fficonfig.py
- pass "-m64" to the CFLAGS when building the _ctypes.so extension since as is the CFLAGS are reset
- fficonfig.py is missing - use the fixed one
- ffi_common.h isn't in the right place - fix include paths?
polybori
oddity: The dynamic libs are not named properly, i.e. they are straight up bundles [mabye my fault?]

sage -b: devel/sage/c_lib/SConstruct
## We want the debug and optimization flags, since debug symbols are so useful, etc. env.Append( CFLAGS="-O2 -g -m64" ) env.Append( CXXFLAGS="-O2 -g -m64" )
