[Numpy-discussion] New to ctypes. Some problems with loading shared library.
Tue Feb 5 10:25:47 CST 2008
I got ctypes installed and passing its own tests. But
I cannot get the shared library to load. I am using
Mac OS X 10.4.11, Python 2.4 running through the
I am using Albert Strasheim's example on
http://scipy.org/Cookbook/Ctypes2 except that I had to
remove the defined 'extern' for FOO_API since the gcc
compiler complained about two 'externs' (I don't
really understand what the extern does here anyway).
My make file for generating the library is simple,
# ---- Link ---------------------------
test1ctypes.so: test1ctypes.o test1ctypes.mak
gcc -bundle -flat_namespace -undefined suppress -o
# ---- gcc C compile ------------------
test1ctypes.o: test1ctypes.c test1ctypes.h
gcc -c test1ctypes.c -o test1ctypes.o
This generates the file test1ctypes.so. But when I
try to load it
import numpy as N
import ctypes as C
_test1 = N.ctypeslib.load_library('test1ctypes', '.')
I get the error message,
6): image not found
I've been googling for two hours trying to find the
problem or other examples that would give me a clue,
but no luck.
Any ideas what I'm doing wrong? Thanks for any clues.
