Anyone know what this osmocom_siggen error is?

Projects LimeSDR
#1

I see osmocom interact with my LimeSDR but it just gets stuck and the gui never wants to open?

Does the /home/sigintos/.gnuradio/prefs/ directory exist and can your user create files in it?

#3

It exist but I don’t see any files in it aside from: vmcircbuf_default_factory. That’s the only file I see and its contents are: gr::vmcircbuf_sysv_shm_factory

#4

I also get this error in GNU Radio:

Done (return code 1)

It seems Osmocom transmission wont work for me in any capacity.

#5

The two most common reasons to get the error -

RuntimeError: SoapySDR::Device::make() no match

1). You do not have the SoapySDR lime libraries installed.

2). You have two versions of the SoapySDR libraries installed and you are using the wrong one with gnuradio-companion. You can check for two versions with the command -

sudo find / -name “modules0*”

#7

Yes I’m on Bionic Beaver and have both libsoapysdr0.6 and libsoapy0.7 installed. 0.7 undoubtably came when I installed gnuradio and 0.6 came with gr-osmosdr. I removed 0.6 by removing gr-osmosdr & packages but I’m at a loss I don’t know how to install the compatible gr-osmosdr for 0.7. Do you have any ideas? I’ve been plagued with this problem for a couple weeks now.

#8

If you can do a

sudo apt -y install limesuite

followed by a 

sudo apt -y install gr-osmosdr

and it works you are all set but if that does not work it gets tricky.
