include 64-bit OS X gfortran in standard SAge

[williamstein]

This will make the tarball bigger (by 24MB), but is the only way to go at present. With this one spkg update, building Sage 64-bit on OS X will be as simple as typing:

export SAGE64="yes"
make

For the 64-bit version, is there a reason to copy a big bzipped tar file to SAGE_LOCAL? If not, then I think that in the file [{{/src/gfortran/fortran-OSX64-20090120/spkg-install}}}, the lines

cp src/gfortran-4.2.3.tar.bz2 $SAGE_LOCAL
cd $SAGE_LOCAL; tar -xjf gfortran-4.2.3.tar.bz2 -C .

should be changed to something like

cd $SAGE_LOCAL; tar -xjf $CUR/gfortran-4.2.3.tar.bz2 -C .

Also, there should be a message about the 64-bit version being installed: in the main spkg-install file, the function install_fortran_osx64 could start with a message like

print "Installing OSX 64-bit gfortran compiler"

Some people who are sticklers might complain about the format of SPGK.txt, but I don't care that much.

Done. I have added your reviewer comment to src/gfortran/fortran-OSX64-20090120/spkg-install and committed this change in your name.

Also, there should be a message about the 64-bit version being installed: in the main spkg-install file, the function install_fortran_osx64 could start with a message like

print "Installing OSX 64-bit gfortran compiler"

Done. This line is now in the main spkg-install. The change has been committed in your name.

Some people who are sticklers might complain about the format of SPGK.txt, but I don't care that much.

Also taken care of. An updated spkg with reviewer changes can be found at

http://sage.math.washington.edu/home/mvngu/release/spkg/standard/fortran-20071120.p6.spkg

I'm reviewing the actual building of that package now. You're more than welcome to try building Sage 4.1.2.alpha2 from source with this updated Fortran package. The more the merrier :-)

This results in the following error:

**********************************************************************






Error installing Fortran: Error installing OS X 64-bit gfortran

The actual command should be

cd $SAGE_LOCAL; tar -xjf $CUR/src/gfortran-4.2.3.tar.bz2 -C .

Notice the "src" part. The updated spkg includes this fix.

Mac OS 10.5: open a new terminal (and doublecheck that SAGE64 is not set). Untar sage-4.1.2.alpha2 and replace the fortran package there with the new one. Type 'make' and wait: I see

Installing OS X 64-bit gfortran compiler

I don't know why...

Almost perfect. To make it perfect, I would like to see this change from mvngu's version re-incorporated:

Also, there should be a message about the 64-bit version being installed: in the main spkg-install file, the function install_fortran_osx64 could start with a message like

print "Installing OSX 64-bit gfortran compiler"

[williamstein]

comment:8

OK, I refreshed the spkg with that.

[jhpalmieri]

comment:9

Looks good to me. The SPKG.txt file isn't in the right format, but I don't care.

comment:10

I've made a major improvement to how this spkg detects "64 bit" so it will work when building Sage on OS X 10.6 without explicitly specifying SAGE64. Instead of using that flag it simply checks the bitness of Python. Without this we would get a 32-bit compiler, which is completely wrong.

New spkg up at

http://sage.math.washington.edu/home/mvngu/release/spkg/standard/fortran-20071120.p9.spkg

The only changes from .p8 are:

• remove junk files: spkg-install~ and SPKG.txt~
• add info to SPKG.txt

Changed merged from Sage 4.1.2.alpha3 to Sage 4.1.2.alpha4

There is no 4.1.2.alpha3. Sage 4.1.2.alpha3 was William Stein's release for working on making the notebook a standalone package.
