[Discuss-gnuradio] _gnuradio_swig_python import error on Mac OS X

[Jonathan Jacky]

I build gnuradio-core from the 2.5 tarball on Mac OS X.

After make and make install completed without error messages,
I tried make check in my gnuradio-core-2.5. (I learned here in January 
that on OS X, make install must precede make check).

Every one of the qa_*.py checks fails with this same traceback:

Traceback (most recent call last):
  File "./qa_add_and_friends.py", line 23, in ?
    from gnuradio import gr, gr_unittest
  File 
"/Users/jon/gnuradio/gnuradio-core-2.5/src/python/gnuradio/gr/__init__.py\
", line 27, in ?
    from gnuradio_swig_python import *
  File 
"/Users/jon/gnuradio/gnuradio-core-2.5/src/lib/swig/gnuradio_swig_python.\
py", line 5, in ?
    import _gnuradio_swig_python
ImportError: No module named _gnuradio_swig_python

I find I have these files under my gnuradio-core-2.5:

 gnuradio-core-2.5/src/lib/swig/_gnuradio_swig_python.la
 gnuradio-core-2.5/src/lib/swig/.libs/_gnuradio_swig_python.la
 gnuradio-core-2.5/src/lib/swig/.libs/_gnuradio_swig_python.lai
 gnuradio-core-2.5/src/lib/swig/.libs/_gnuradio_swig_python.dylib

I find that make install also installed these:

 /Library/Python/2.3/gnuradio/gr/_gnuradio_swig_python.la
 /Library/Python/2.3/gnuradio/gr/_gnuradio_swig_python.dylib

However, I don't find a _gnuradio_swig_python.py, .pyc, or .pyo anywhere

I thought it might be a problem with the Python path, but python can import 
other .py files from under /Library/Python/2.3 without an explicit path being 
given.  In a python terminal session, "print sys.path" shows the path includes
'/System/Library/Frameworks/Python.framework/Versions/2.3/lib/python2.3/
site-packages', which is a link to /Library/Python/2.3.

Any suggestions?  Am I supposed to have a _gnuradio_swig_python.py,.pyc, 
or .pyo somewhere?  Is python supposed to import 
_gnuradio_swig_python.la,.lai, or .dylib?
