Mac OS X Lion Python Ctype CDLL error lib.so.6 : image not found
macos, osx-lion, python
Solution
Shared libraries on Mac OS X tend to have the extension `.dylib` instead of `.so`. In this case, `/usr/lib/libc.dylib` is what you want so load `libc.dylib`.
Problem
I am a beginner in Python. When I tried the following Python sample code with type library on Mac OS X Lion: ``` #hello.py from ctypes import * cdll.LoadLibrary("libc.so.6") libc = CDLL("libc.so.6") message_string = "Hello World! Hello Python!\n" libc.printf("Testing :%s",message_string) // ``` An error occurred as following: ``` Traceback (most recent call last): File "cprintf.py", line 2, in <module> cdll.LoadLibrary("libc.so.6") File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 431, in LoadLibrary return self._dlltype(name) File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 353, in __init__ self._handle = _dlopen(self._name, mode) OSError: dlopen(libc.so.6, 6): image not found ``` Can anyone tell me what's the matter? BTW, I tried this on Windows and Linux; it worked well. Need I make some configuration for ctype. Thanks very much, Ricky
