This fixes the build problem on i386 (although we're stuck with
possible run-time problems when numpy is built with the newer binutils
until the latest fenv.h changes are backported to all supported
versions of FreeBSD), but this code is machine-dependent, and fenv.h
needs to be selected based on ARCH.
You might do instead something like:
...
.if exists(${LOCALBASE}/bin/as)
.if ${ARCH} == "i386"
FP_ARCH= i387
.else
FP_ARCH= ${ARCH}
.endif
MASTER_SITES+= http://svn.freebsd.org/base/head/lib/msun/%SUBDIR%/:fp
MASTER_SITE_SUBDIR+= ${FP_ARCH}/:fp
DISTFILES+= fenv.h:fp
.endif
...
pre-configure:
.if exists(${LOCALBASE}/bin/as)
${CP} ${DISTDIR}/fenv.h ${WRKSRC}/numpy/core/include/numpy/fenv/fenv.h; \
${PATCH} ${PATCH_DIST_ARGS} < ${FILESDIR}/fenv.patch; \
.endif
...
