Sage FreeBSD 7.x/amd64 and 8-current/amd64 build notes for Sage 3.4

Contents

Overall build environment differences

• sh and /bin/sh are a POSIX shell, rather than bash.

• make is the BSD make, not GNU make

Preparatory work

• Install ports/shells/bash or ports/shells/bash3 (I used 3.2.48)
• Install ports/devel/gmake
• Install ports/lang/gcc43 - FreeBSD no longer ships with a Fortran compiler by default. I tried using g95 but ran into problems.
• Install ports/devel/autoconf262
• Install ports/converters/libiconv - This may be optional but is definitely used if found

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

Building Sage

The Sage build chain automatically unpacks and builds each spkg, however in order to build on FreeBSD, a number of spkgs need patching. Rather than manually unpack, patch and repack each spkg, I have instead modified base/sage-spkg to automatically apply a local patch if it exists.

On FreeBSD 7.x

• Unpack sage-3.4.tar

• cd sage-3.4

• Unpack sage-3.4.tgz. This installs the symlinks listed below as well as various patches. Note that the patches in spkg/patches.save are not currently applied.

• Build Sage

  • SAGE_FORTRAN_LIB=/usr/local/lib/gcc-4.3.4/libgfortran.so gmake

On FreeBSD 8.x

• Unpack sage-3.4.tar

• cd sage-3.4

• mkdir -p local/bin spkg/patches

• Create symlinks to mask name differences.

  • ln -s /usr/local/bin/gmake local/bin/make

  • ln -s /usr/local/bin/bash local/bin/sh

  • ln -s /usr/local/bin/gcc43 local/bin/gcc

  • ln -s /usr/local/bin/g++43 local/bin/g++

  • ln -s /usr/local/bin/gfortran43 local/bin/gfortran # specifying SAGE_FORTRAN isn't sufficient

• Unpack the attached shar archive: sage-3.4.shar

• Apply patches to base build system

  • patch < spkg/patches/base.patch

• Build Sage

  • CPPFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib gmake

Current Status

Currently, the following tests fail on FreeBSD 7.x/amd64. One test runs out of swap (process exceeds 4GB) and there are a number of core dumps. Full details here.

Notes on spkgs and attached patches

A number of the following patches change make to ${MAKE} and/or use gmake instead of make on FreeBSD. The former is the recommended way to recursively invoke make to ensure that the subordinate make is the same as the parent make (and also ensures that the two make instances will communicate on things like '-jX'). The latter fixes date from early versions of this patchset before I decided to symlink GNU make as local/bin/make and should no longer be necessary (though I haven't verified this).

base.patch

base.txt

• The patch to base/sage-spkg enables the local patching that the rest of the patches rely on. Note that this patch is not intended to be merged into sage but provides a convenient mechanism to apply local patches without requiring that the spkg files are locally re-rolled.
• The patch to standard/deps ensures that bash is used.

atlas-3.8.3.p0

Various fixes to make it compile on FreeBSD

• sysctl is not in the default user path so use an explicit pathname (optional)

• The newer AMD CPUs all identify as 'Athlon' so use the existence of multiple cores to distinguish between K7 (i386) and later (Hammer) CPUs. (optional)
• Correct various sysctl OIDs to match the names FreeBSD uses. (optional)

• FreeBSD uses an '_fbsd' suffix on the ELF format supported by ld - prevents ld: unrecognised emulation mode: elf_x86_64 error during atlas build.

• Treat shared libraries the same as Linux - otherwise they aren't correctly detected by (eg) numpy.

• Building the libclapack.so should result in a libclapack.so being created. This appears to be a copy-and-paste error in atlas

clisp-2.46.p7

The FreeBSD/amd64 process memory map is incompatible with the memory mapping done by clisp. The patch moves the memory map down 8 bits. An alternative (used by the FreeBSD clisp port) is to pass --disable-mmap to configure.

eclib-20080310.p7

Various 'make' fixes - see above.

ecm-6.2.1.p0

Portability fixes so the configure script works with a POSIX shell.

fortran-20071120.p5

FreeBSD doesn't have a '-f' option on readlink

freetype-2.3.5.p0

Various 'make' fixes - see above.

gap-4.4.12.p1

Patches (mostly taken from the FreeBSD port) to make gap compile on FreeBSD.

gd-2.0.35.p1

Patch needed to make gd correctly detect libiconv. Otherwise it fails with:

iml-1.0.1.p11

Remove a stray warning by not attempting to execute ${CFLAGS}

libgcrypt-1.4.3.p0

libm4ri-20090128

The configure script is pretty much beyond redemption on FreeBSD. Instead fix the autoconf inputs to support FreeBSD and re-run autoconf. The libm4ri fixes have all be forwarded to the libm4ri maintainer and accepted by them.

Also ensure that CPPFLAGS from the environment is passed into the libm4ri build process.

linbox-1.1.6

Detect FreeBSD and appropriately select BLAS and Atlas libraries.

matplotlib-0.98.5.3rc0-svn6910.p3

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'.

mpfr-2.4.1

Portability fixes so the configure script works with a POSIX shell.

ntl-5.4.2.p6

Correctly pass -fPIC when building the shared library.

numpy-1.2.0.p0

Correctly pass -fPIC when building the shared library. Various fixes to handle correct fortran and library detection on FreeBSD.

pari-2.3.3.p0

FreeBSD refers to the x86_64 architecture under its original name of 'amd64' so use this as an alias for x86_64. The `-fPIC' fix is needed to correct:

gcc  -o libpari-gmp.so.2.3.3 -shared -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer -Wl,-shared,-soname=libpari-gmp.so.2 mp.o mpinl.o Flx.o Qfb.o RgX.o alglin1.o alglin2.o arith1.o arith2.o base1.o base2.o base3.o base4.o base5.o bibli1.o bibli2.o buch1.o buch2.o buch3.o buch4.o galconj.o gen1.o gen2.o gen3.o ifactor1.o perm.o polarit1.o polarit2.o polarit3.o rootpol.o subcyclo.o subgroup.o trans1.o trans2.o trans3.o anal.o compat.o default.o errmsg.o es.o init.o intnum.o members.o sumiter.o aprcl.o elldata.o elliptic.o galois.o groupid.o kummer.o mpqs.o nffactor.o part.o stark.o subfield.o thue.o -lc -lm -L/home/pjeremy/sage-3.4/local/lib -lgmp

python-2.5.2.p9

Include the python patches from the FreeBSD port. This adds support for FreeBSD 7 and 8.

The patch to Lib/test/seq_tests.py disables the memory-exhaustion tests on 64-bit architectures. Otherwise, those tests allocate a 32GB chunk of memory and attempt to use it all. The default process size on FreeBSD/amd64 allows the allocation to succeed but actually using the memory generally results in swap exhaustion. This fix comes from python-2.5.4.

r-2.6.1.p22

Pass CFLAGS, CPPFLAGS and LDFLAGS from the environment into the build process.

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.

readline-5.2.p6

Chase shared library name difference on FreeBSD. Without this if, the build fails with

Readline's build claims to have finished, but files that should have been built weren't.

Applying the fix from FreeBSD ports to remove the check on objformat does not correct the above problem.

sage-3.4

FreeBSD does not include a definition for log2() in libm. Use a simplistic definition of log2(x) = log2(e) * ln(x)

sage_scripts-3.4

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.

scipy-20071020-0.6.p4

scipy uses local/lib/python2.5/site-packages/numpy/distutils/fcompiler/gnu.py to locate a Fortran compiler. This code only looks for g77, f77, gfortran and f95. Whilst it has some patches to look in sage_fortran, this does not appear to work for scipy. The work-around is to create a symlink to the actual Fortran compiler in local/bin, otherwise the scipy build fails with:

singular-3-0-4-4-20080711.p4

By default, you get the following, which is corrected by the patch to singuname.sh:

Correct configure script for amd64 by patching the autoconf inputs and re-running autoconf. This corrects a problem where linking libsingular.so reports lots of undefined references to both internal om* functions and functions within libncurses.

Several other trivial fixes to support dynamic linking on FreeBSD/amd64.

The rationale behind original code to disable __cplusplus in cf_gmp.h is unclear. The result using gcc4.3 on FreeBSD is definitely broken as cf_gmp.h includes gmp.h which includes string.h - which results in strcat() and friends being declared without a surrounding extern "C" {...} block. This causes the code to linvoke (non-existent) C++ versions of strcat(char *, const char *), rather than the standard C library strcat(). Commenting out this code fixes the problem. The failure looks like:

tachyon-0.98beta.p8

tachyon does include BSD support (though the code advises that it hasn't been tested for a while). Looking though the source code, there's no obvious bitrot so add FreeBSD support to the spkg-install script. As noted, I haven't added support for either threaded or 64-bit tachyon. The former shouldn't be too difficult to add and the MacOS-X port implies it is optional. The 64-bit support is solely an optimisation - a test to detect wrap-around of long integers is removed since wrap-around isn't possible with 64-bit longs.
