Isn't that the line right before the first report of the error?
cc -shared -pthread -mtune=generic -msse -msse2 -msse3 -mfpmath=sse -O2
-fno-strict-aliasing -pipe -Wl,-rpath=/usr/local/lib/gcc45
build/temp.freebsd-8.2-PRERELEASE-i386-2.7/build/src.freebsd-8.2-PRERELEASE-i386-2.7/numpy/core/src/_sortmodule.o -Lbuild/temp.freebsd-8.2-PRERELEASE-i386-2.7 -lm -o build/lib.freebsd-8.2-PRERELEASE-i386-2.7/numpy/core/_sort.so
I wanted the confirmation of exact command that failed. If your
citation above is right, then port _does not_ use gcc45 to do linkage
of the module. Generally, crtbegin/crtend.o come from the compiler
installation, so I am suspicious at least to report of use of
/usr/lib/crtbegin.So.
Can you enter the port build directory and execute the same command
manually, substituting "cc" with full path to gcc45 ?
Done. Replacing "cc" with "gcc45" built the library without any error.
(I didn't need to specify the full path to gcc45.)
So the question is, why is cc being invoked in the first place? As far
as I know, I'm not doing anything to force using it. Something seems
to have gone wrong during py-numpy's configtests...
After some sleuthing I tried:
# make LDSHARED="gcc45 -shared" install
This seems to have worked. The build and install now succeeds without
complaint. Hooray!
So where did the "cc" come from?
/usr/local/lib/python2.7/distutils/unixccompiler.py has the following line:
'linker_so' : ["cc", "-shared"]
The base class defined in ccompiler.py sets linker_so to ${LDSHARED} if
that environment variable is defined, and that assignment seems to be
inherited all the way down into the numpy scripts. Otherwise, we get
the value defined in unixccompiler.py.
