Description Michael Yang 2009-07-28 15:50:38 UTC 
numpy-1.3.0 ebuild is pulling in /usr/include/fenv.h through #include <fenv.h>
This causes a problem building umathmodule.o and _capi.o since /usr/include/fenv.h declares __status variable as int whereas __uint16_t should be used.  Attached ebuild patch alters _capi.c and ufuncobject.h to #include fenv.h in the numpy distribution, avoiding <fenv.h>

Reproducible: Always

Steps to Reproduce:
1. emerge =numpy-1.3.0

Actual Results:  
build/src.freebsd-7.2-RELEASE-i386-2.6/numpy/core/src/umathmodule.c
/usr/include/fenv.h: Assembler messages:
/usr/include/fenv.h:156: Error: suffix or operands invalid for `fnstsw'

Expected Results:  
success

Comment 4 Michael Yang 2009-08-03 22:58:40 UTC 
This patchset is OK for building numpy-1.3.0 but needs another patch to satisfy a further emerging of >=sci-libs/scipy-0.7.0

scipy pulls in the patched ufuncobject.h through line 13 in _cephesmodule.h:

#include "numpy/ufuncobject.h"

which fails during compile to find fenv/fenv.h or fenv/fenv.c.  The -I include flags in scipy attempt to scan $EPREFIX/usr/lib/python2.6/site-packages/numpy/core/include/numpy and fails since numpy/core/setup.py in numpy didn't install the fenv directory.

The attached patch alters setup.py to install the fenv directory.

what still needs to be done for 1.4.0?
