Sage FreeBSD 7.x and 8.x build notes for Sage 4.1 and 4.1.1

Overall build environment differences

Preparatory work

It's possible there are other dependencies, I haven't tried building sage in a clean (tinderbox) environment.

Building Sage

On FreeBSD 7.x

Current Status

Currently, the following tests fail on FreeBSD 7.2/i386 (the same tests fail on both versions of sage). Full logs at sage-4.1.freebsd32.test.log and sage-4.1.1.rc2.freebsd32.test.log.

        sage -t  "4.1/devel/sage/sage/ext/fast_callable.pyx"
        sage -t  "4.1/devel/sage/sage/rings/number_field/number_field.py"
        sage -t  "4.1/devel/sage/sage/rings/tests.py"
        sage -t  "4.1/devel/sage/sage/rings/integer.pyx"
        sage -t  "4.1/devel/sage/sage/schemes/elliptic_curves/period_lattice.py"
        sage -t  "4.1/devel/sage/sage/misc/getusage.py"
        sage -t  "4.1/devel/sage/sage/libs/pari/gen.pyx"

The actual failures are a mixture of:

Notes on spkgs and attached patches

The following lists versions for sage-4.1. The actual patch content remains the same for sage-4.1.1.rc2, though some patch names (as well as internal pathnames) change.

atlas-3.8.3.p5

Various fixes to make it compile on FreeBSD

matplotlib-0.98.5.3rc0-svn6910.p4

Add hooks to ensure that the local Sage versions of dependencies are used by FreeBSD. Otherwise you get:

Add support for FreeBSD later than 6.x. Otherwise you get :

gcc4.3 (though not gcc4.2) appears to define putchar() in a way that breaks the putchar() definitions inside ttconv. I couldn't quickly identify what the underlying cause was so I took the easy way out and undef'd the offending putchar() macro.

Individual character bounding boxes in AFM files do not have to be integral so convert each bounding box to a list of floats, rather than a list of ints. This corrects a problem where most of the tests would fail with ValueError: invalid literal for int() with base 10: '539.621'.

All three sub-patches are in #5873

numpy-1.2.0.p0

r-2.6.1.p23

Pass CFLAGS, CPPFLAGS and LDFLAGS from the environment into the build process. This also corrects a typo in CPPFLAGS.

Note that FreeBSD needs the path to libiconv to be explicitly specified. In theory, --with-libiconv-prefix should work but configure script is broken and ignores that path when looking for libiconv. Hard-wire /usr/local/include and /usr/local/lib via xxFLAGS.

Note that the X11 detection in spkg-install will not work anywhere other than Linux. This needs future work.

These patches are all local to Sage.

sage-4.1

sage_scripts-4.1

Patch sage-spkg to apply local patches. This patch also disables deletion of the spkg/build/FOO temporary directories - which was useful during porting. This latter patch can be safely removed.
