Hello All,

Don't know if this went through the first time or not. . .

Hello All,

Most likely this is really just a question for David Cournapeau. . . 

Am having a bit of trouble apparently resulting from being a python newbie.

I have numpy, scipy, and pyaudiolab up and going, but am having trouble getting pysamplerate to happen. In attempting to install pysamplerate, I have run pysamplerate's setup.py in a python interpreter, choosing task [2], the install option. That does the following:



samplerate_info:
  libraries samplerate not found in /Library/Frameworks/Python.framework/Versions/2.5/lib
  FOUND:
    libraries = ['samplerate']
    library_dirs = ['/usr/local/lib']
    fulllibloc = /usr/local/lib/libsamplerate.so.0
    fullheadloc = /usr/local/include/samplerate.h
    include_dirs = ['/usr/local/include']

****************************************


The latest version of libsamplerate has been installed in /usr/local/lib/, with ls libsamplerate* listing the following:

libsamplerate.0.1.1.dylib	libsamplerate.dylib
libsamplerate.0.dylib		libsamplerate.la
libsamplerate.a



Starting a new python interpreter, attempting to import pysamplerate, i get:


>>> import pysamplerate
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pysamplerate.py", line 23, in <module>
    _src = cdll.LoadLibrary('/usr/local/lib/libsamplerate.so.0')
  File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ctypes/__init__.py", line 423, in LoadLibrary
    return self._dlltype(name)
  File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ctypes/__init__.py", line 340, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: dlopen(/usr/local/lib/libsamplerate.so.0, 6): image not found


****************************************

What I see is that libsamplerate.so.0 is missing from the /usr/local/lib directory. Is this a file that should be created by pysamplerate's setup.py?

Anyway, I'm doing something wrong. Sure it is rather simple.


Thanks for the help.
