I am new to the list. I have used the rtl-sdr/osmosdr blocks in gnuradio companion before under Ubuntu, but am having problems getting them set up under Mac OS.
My gnuradio/grc install used the macports facility. Took a bit of time to get everything to compile, but grc comes up okay.
I have successfully downloaded, cmake/make, and installed the rtl-sdr and gr-osmocom packages from git.
I had to move all the installed files from /usr/local to /opt/local in order to get everything into the right place for the macports gnuradio to find it.
What works:
I can load grc and see the osmocom/rtl-sdr blocks. I can add and modify them as usual.
Here's a screen shot:
What doesn't work:
When I generate/run the flow graph, I get messages indicating that the osmosdr module cannot be found:
---
Executing: "/Users/mcquiggi/Desktop/top_block.py"
Traceback (most recent call last):
File "/Users/mcquiggi/Desktop/top_block.py", line 19, in <module>
import osmosdr
ImportError: No module named osmosdr
>>> Done
---
Note also that from my xterm if I enter simply:
Kevins-MacBook-Air:~ mcquiggi$ python -c "import osmosdr"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named osmosdr
Kevins-MacBook-Air:~ mcquiggi$
I get a python error.
There is an 'osmosdr' directory in /opt/local/lib/python2.7/site-packages/.
What I have tried:
- creatling a soft link called 'osmosdr' (ln -s) in /opt/local/lib/python2.7/ to /opt/local/lib/python2.7/site-packages/osmosdr
- setting PYTHONPATH to /opt/local/lib/python2.7/site-packages/
Here is the contents of /opt/local/lib/python2.7/site-packages/osmosdr:
Kevins-MacBook-Air:~ mcquiggi$ ls /opt/local/lib/python2.7/site-packages/osmosdr
__init__.py _osmosdr_swig.so osmosdr_swig.pyo
__init__.pyc osmosdr_swig.py
__init__.pyo osmosdr_swig.pyc
Kevins-MacBook-Air:~ mcquiggi$
So it looks like it -may- be a simple problem to solve, but I lack the necessary knowledge of how osmosdr integrates with gnuradio.
Any help appreciated,
Kevin
