Re: Question about cmake error when installing gr-sigmf

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>
_prepare_sigmf_swig()
File "/usr/local/lib/python2.7/dist-packages/gr_sigmf/__init__.py", line 43, in _prepare_sigmf_swig
import gr_sigmf_swig
File "/usr/local/lib/python2.7/dist-packages/gr_sigmf/gr_sigmf_swig.py", line 17, in <module>
_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

Sure I’d be interested in those screen caps.

Fantastic, thanks Marcus!! Installed libboost-regex and libboost-regex-dev, tried cmake again, it gave me another error that I was missing Doxygen and boost_log, so I installed Doxygen and libboost-log-dev and libboost-log, and all seems well now! The blocks show up in the GRC and everything. I'll try testing them on some SigMF files from the Allen Array tomorrow. Can send a screen capture when I get it working if you like :)

Thanks again Marcus! Have a good evening.

Hi all,

Hope you are well! I had a question regarding how to install gr-sigmf (https://github.com/skysafe/gr-sigmf). I'm running GNU Radio version 3.7.11 in an ubuntu 18.04 virtual machine on a Windows 8.1 PC (my ubuntu laptop is on the blink), which I installed using sudo apt install gnuradio. I attempted to install gr-sigmf following the steps outlined in the github page, but when I get to the cmake stage it goes awry. I've attached the output from CMake as well as the CMakeLists.txt file.

Do you have any advice as to how I could get this to work? Thanks so much for any suggestions you might have!

Take care,

Ellie

You could try:

sudo apt-get install libboost-regex libboost-regex-dev

Then re-do your Cmake and friends.

I've never used gr-sigmf (he says, sheepishly), although I did contribute to early discussions about features for scientific applications of it...
