[Numpy-discussion] F2PY error : ... on platform 'posix' with 'gcc' compiler

[Arthur Bousquet]

Ok, so I re-compiled python (without framework), numpy,... So I can compile
my lib (libsw) now, bu I can't called it from python. I got this error :

Arths-MacBook-Pro:run_1 arthbous$ ./run.sh
Traceback (most recent call last):
  File "../main.py", line 23, in <module>
    import libsw as lsw
ImportError: dlopen(/Users/arthbous/Documents/SW/sw-v2.3/libsw.so, 2): no
suitable image found.  Did find:
    /Users/arthbous/Documents/SW/sw-v2.3/libsw.so: mach-o, but wrong
architecture

It seems to compile for the wrong architecture. Do you know about this ?

Thank you.

- Arthur
