Sage FreeBSD 7.0 build notes for Sage 3.2.3

Notes on spkgs

gmp-4.2.2.fake

broken, vanilla gmp 4.2.2 or eMPIRe works

flint

gcc complaints about C99 in gmp.h - fallback to C89

gd

ivonc issues - change back ICONV_CONST to const

atlas

no CPU detection - 3.8.2 ought to help

numpy

problems with ATLAS detection - bombs out building lapack_lite extension
-shared flag missing - just like Cygwin

matplotlib

KeyError: 'freebsd7' - add to setupext.py

singular

/usr/home/sage/sage-3.2.rc1/local/lib/libsingcf.a(NTLconvert.o)(.text+0x2815): In function `convertZZ2CF(NTL::ZZ)':

/usr/home/sage/sage-3.2.rc1/spkg/build/singular-3-0-4-4-20080711.p1/src/factory/NTLconvert.cc:649: undefined reference to `strcat(char*, char const*)'

fix: "#include <cstring>" in NTLconvert.cc

r

disable inconv: --with-iconv=no

Sage library

long double version problem, i.e. sqrtl

cc1plus: warning: command line option "-Wstrict-prototypes" is valid for C/ObjC but not for C++
sage/combinat/partitions_c.cc: In function 'void initialize_constants(unsigned int, unsigned int)':
sage/combinat/partitions_c.cc:788: error: 'sqrtl' was not declared in this scope

Fix: same solution as __sun

log2 undefined

ImportError: /usr/home/sage/sage-3.2.rc1/local/lib/python2.5/site-packages/sage/ext/fast_eval.so: Undefined symbol "log2"

Fix: define "fake" log2

tachyon

Tachyon build for FreeBSD not implemented (for SAGE)
