Hi again, all --

Ok, so thanks to Marcus I was able to get through installing gr-sigmf. However, I just attempted to make a flow graph using a sigMF source and unfortunately have hit another roadblock; when I attempt to run the flowgraph (attached; it is not well-developed yet but I was just testing some things), I get the following error:

Traceback (most recent call last):
  File "/home/ewhite/research/ewhite-bl-seti/top_block.py", line 29, in <module>
    import gr_sigmf
  File "/usr/local/lib/python2.7/dist-packages/gr_sigmf/__init__.py", line 63, in <module>

    import gr_sigmf_swig

    _gr_sigmf_swig = swig_import_helper()
  File "/usr/local/lib/python2.7/dist-packages/gr_sigmf/gr_sigmf_swig.py", line 16, in swig_import_helper
    return importlib.import_module('_gr_sigmf_swig')
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
ImportError: No module named _gr_sigmf_swig

Is there some additional package or module I need to install here, or did something go wrong when I installed the blocks? If anyone has any suggestions on how to fix this I'd be really grateful.

Have a good day and take care!

Thanks,
Ellie


After doing the install, try:

sudo ldconfig

And see if that fixes things.
