Re: Question about cmake error when installing gr-sigmf

It may be the case that gr-sigmf hasn't been converted to gr-3.8 yet. 

The gr-sigmf folks are on this list as far as I know.

Hi Marcus,

Thanks so much for the advice, I really appreciate it! So when I tried that, it did work, and I was able to run a flowgraph successfully in GNU Radio 3.7, so that's good.

In the process of attempting to install some more packages (specifically gr-ata), I found that I needed to upgrade to GNU Radio version 3.8 or 3.9. So I followed these instructions: https://wiki.gnuradio.org/index.php/InstallingGR#Ubuntu_PPA_Installation to install GNU Radio 3.9.0. Then, I deleted the gr-sigmf directory I had cloned and built from, then attempted to re-install gr-sigmf (again using these instructions: https://github.com/skysafe/gr-sigmf). For some reason I now can get through running cmake, but things get stuck when I try to run make; here's the output:

Do you have any idea what might be going on here, or what I should do next? Thanks Marcus! Have a good morning.

Cheers,

Ellie

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:

    __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.
