[SciPy-user] Problem importing scipy compiled with intel compiler: New Problem :(

[Sourish Basu]

Hi all,

    I'm following up to my own post for archival purposes. It turns out
that the compiler was (for some reason) not linking to the correct
libgcc. Doing this:

[sourish at nanolab Sources]$ nm /lib/ssa/libgcc_s.so.1 | grep fixunsdfdi
00001a60 T __fixunsdfdi
[sourish at nanolab Sources]$

and also doing an "ldd" on _lbfgsb.so I realized that it wasn't linking
to libgcc. So I changed my install command to:

python setup.py build_clib --fcompiler=intel build_ext --fcompiler=intel
-L/lib/ssa -lg2c -lgcc_s install

and everything is fine and dandy now!
