Sage FreeBSD 8.x build notes for Sage 4.3

Note that this is a work-in-progress and not currently complete


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 8.x

FreeBSD 7.x hasn't been tested with Sage 4.3 but is expected to work.

Note that it's not currently possible to use gcc44/g++44 to build Sage - configuration errors in the FreeBSD port of gcc44 means that the wrong shared libraries get used if this is attempted. See

The gmake to make symlink is necessary to compile (eg) eclib - which is documented as requiring GNU make, and has this symlink as a suggested workaround.

Current Status

Currently, the following tests fail on FreeBSD 8.0-STABLE/amd64. Full logs at sage-4.3.freebsd8.0-amd64.test.log.

The actual failures indicate that the port still needs significant work and include:

Notes on spkgs and attached patches



Various fixes to make it compile on FreeBSD

Trac ticket: #7827


FreeBSD uses the same invocation as Linux to build shared libraries. This patch is necessary to allow cliquer to build.

Trac ticket: #7824


Patches (mostly taken from the FreeBSD port) to make gap compile on FreeBSD 8.x. These patches should be optional on FreeBSD/7.x.

Chase shared library name difference on FreeBSD. Sage local patch. Otherwise the gnutls build fails similar to:

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:

Trac ticket: #7825 Reported upstream as


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. Without this change, you get:

checking iconv.h usability... no
checking iconv.h presence... no
checking for iconv.h... no
checking for iconv... no
checking for iconvlist... no
configure: error: --with-iconv=yes (default) and a suitable iconv is not available
Error configuring R.

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.

readline-6.0.p1/spkg-install contains a typo in some FreeBSD-specific code, leading to the following error:

/bin/sh ../support/shlib-install -O freebsd8.0 -d /home/peter/sage/sage-4.3/local/lib -b /home/peter/sage/sage-4.3/local/bin -i "/usr/bin/install -c -m 644"
install: you may need to run ldconfig
make[1]: Leaving directory `/home/peter/sage/sage-4.3/spkg/build/readline-6.0.p1/src/shlib'
ln: SAGE_LOCAL/lib/ No such file or directory

The affected code is no longer required with readline-6.0 so delete it.

FreeBSD 3.x and later default to ELF, rather then a.out. A utility objformat(1) was temporarily introduced to enable third-party applications to determine te object format. This has now been deleted and code should assume ELF format if it does not exist. Explicitly linking libreadline against libtermcap is necessary to ensure that dependencies are picked up.

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.


By default, you get the following, which is corrected by the patch to

make[2]: Entering directory `/home/peter/sage/sage-4.3/spkg/build/singular-3-1-0-4-20090818.p2/src'
make[2]: *** No rule to make target `distclean'.  Stop.

creating cache ./config.cache

configure: error: Unknown architecture: Check
Unable to configure Singular.

Correct configure script for amd64 by patching the autoconf inputs and re-running autoconf. This corrects a problem where linking 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.
