Sage 64 bit OSX 64 bit build notes for Sage 3.2.3

Notes

The notebook doesn't work unless ctypes are manually build. This is a bug in Python 2.5.2. Need to check Python 2.5.4 and 2.6.1 as well as 3.0 for workarounds.

fortran.spkg

Use OSX-gfortran.spkg (coming soon) which is a repackaged Gfortran 4.2.3 by the R people. It is quad universal.

Make local/bin/sage_fortran like

gfortran -m64 "$@"

Make sure to chmod 755 and extend DYLD_LIBRARY_PATH to include the Fortran runtime - maybe in toolchain?

gmp

use eMPIRe

Python

ctypes broken, use the old workaround, but also look at 2.5.4 and 2.6.1 for potential solutions

atlas

The following error pops up, but it is harmless:

/bin/sh: /Users/michaelabshoff/Desktop/sage-3.2.3-64bit/local/bin/which_fortran: No such file or directory

It should still be fixed.

pynac

No OSX64 bit support yet - an unclean version that builds would be:

         exit 1

r

libpng trouble since the build with a dynamic libpng was fixed recently:

Error in dyn.load(file, ...) :

Analog fix like the one for 32 bit via LD_FLAGS

sagelib

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" )

The above fix needs to be dependent on SAGE64 being set. CXXFLAGS should have -g added, too.

Another problem is that the Sage's libsage.dylib is linked without -m64 - setting LDFLAGS in SConstruct does not fix the problem:

libcsage.dylib:                 Mach-O dynamically linked shared library i386

Building manually works around the problem for now.

Another problem is that the memory.pyx extension needs to be linked against libcsage:

Similar linker fixes are needed for Cygwin

ghmm

ghmm is build 32 bits only

libghmm.1.0.0.dylib:            Mach-O dynamically linked shared library i386
libghmm.1.dylib:                Mach-O dynamically linked shared library i386
libghmm.dylib:                  Mach-O dynamically linked shared library i386

Quick and ugly hack, needs SAGE64 specific cleanup:

We need to enable system malloc for MacIntel since it is only chosen pre default for MacPPC. The ugly hack below needs to be cleaned up:

But at exit we are having problems with double frees:

These also happen on Cygwin, so this needs to be investigated and fixed.
