Sage 64 bit OSX 10.5 build notes for Sage 3.2.3

Notes

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 "[email protected]"

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

gmp

use eMPIRe

Python

The notebook doesn't work unless ctypes are manually build. This is a bug in Python 2.5.2.

The binary _ctypes.so extension was build manually using an older libffi release. See http://sourceware.org/libffi/ - note that the latest release at this point is libffi-3.0.8, released on December 19, 2008.

The issue might be fixable by using an external libffi.

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:

r

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

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

The fix here is to analog to 32 bits to disable aqua support for now.

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" )
env.Append( LINKFLAGS="-m64 -single_module -flat_namespace -undefined dynamic_lookup" )

The above fix needs to be dependent on SAGE64 being set. With the above flags set libcsage.dylib is build as a 64 bit library. The spkg-install does the linking, so everything should work on OSX 64 bit once a clean version of the above proto-patch is merged.

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:

boehmgc

Also is build as 32 bit lib at the moment. Should be trivial to fix via something along the lines of

+export CFLAGS="-O2 -g -m64"
+export LDFLAGS="-m64"

in spkg-install.

singular

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.

The problem is also reproducible on 32 bit OSX when compiling Singular to use the system's malloc:

The problem might be a similar issue as the scope problem found in Cython 0.11-devel in mid January. Note that the majority of the doctests below fail because minpoly() in libSingular segfaults in conditions where it should not be called in the first place.

tachyon

cvxopt

Linker trouble - no clue why yet.

-undefined dynamic_lookup build/temp.macosx-10.3-i386-2.5/C/base.o build/temp.macosx-10.3-i386-2.5/C/dense.o

ld: library not found for -lgfortran
collect2: ld returned 1 exit status

The build issue goes away when installing gfortran directly into $SAGE_LOCAL, but it might also be a failure due to missing gfortran due to env issues. This needs to be verified.

scipy

Import issue with d1mach: Note that d1mach.o manages to be 32 bits:

Sprocketer:scipy-20071020-0.6.p4 michaelabshoff$ file ./src/build/temp.macosx-10.3-i386-2.5/scipy/integrate/mach/d1mach.o
./src/build/temp.macosx-10.3-i386-2.5/scipy/integrate/mach/d1mach.o: Mach-O object i386

This causes import failures all over the place as Scipy's special functions module does fail to import. This seems to be due to scipy using gfortran in some cases when it finds it instead of sage_fortran:

One workaround is to use a dummy gfortran wrapper.

sympow

For now sympow is build in 32 bit mode, but it works:

Sprocketer:sage-3.2.3-64bit michaelabshoff$ file local/lib/sympow/sympow 
local/lib/sympow/sympow: Mach-O executable i386

Since OSX will always have a 32 bit runtime this is something we should be able to live with.

A lot of the above are segaults caused by the tentative Singular vs. Givaro collision.

Program exited with code 01.

The above problem is caused by the IPython import. The problem goes away if we disable the following libedit import test in rlineimpl.py

uses_libedit = False
if sys.platform == 'darwin' and have_readline:
    import commands
    (status, result) = commands.getstatusoutput( "otool -L %s | grep libedit" % _rl.__file__ )
    if status == 0 and len(result) > 0:
        # we are bound to libedit - new in Leopard
        _rl.parse_and_bind("bind ^I rl_complete")
        print "Leopard libedit detected."
        uses_libedit = True

I will open a ticket for this problem shortly. The issue has been reported to the ipython-dev list.
