gr-gsm cmake problem

[Nikos Balkanas]

Hi,

I have many problems upgrading to the latest gr-gsm (v. 0.42.2) with
gnuradio 3.8.3.1.
I get:
"Gnuradio could not be found because dependency Volk could not be found."

Meanwhile gnuradio-config-info shows that volk is installed and enabled:(
This seems like a gr-gsm problem. Any ideas?

TIA
Nikos

Any news?
I even tried gnuradio 3.9.6.
Same result:(

I managed to get past cmake with velikhov's git and gnuradio 3.8.5.
But still I am getting compilation errors:
> Load Error: /home/nikos/work/gr-gsm/apps/grgsm_livemon.grc: Flowgraph invalid
Compilation error

Any ideas?

which ubuntu version you are using while installing gr-gsm?

Ubuntu 20 have smooth installation of gr-gsm while I've faced problems in Ubuntu 18.

I upgraded to Ubuntu 20.04...

Hi

Can anyone send me his grgsm-livemon script for Ubuntu 20.04?
I cannot build it myself and seems that older versions depend on Qt4,
which phased out after bionic (18.04):(

Hi Nikos,

This worked for me using Ubuntu 20.04 (caveat I haven't had to install recently):

Install GnuRadio:

sudo apt install gnuradio gnuradio-dev

Install pre-requisites:

sudo apt install -y cmake git autoconf libtool pkg-config build-essential python3-docutils libcppunit-dev swig doxygen liblog4cpp5-dev gr-osmosdr libosmogsm10 libosmocodec0 libosmogsm-doc libosmosdr0 libosmocodec-doc libosmosdr-dev libosmocoding0 libosmocoding-doc libosmocore libosmocore11 libosmocore-dev libosmocore-doc libosmocore-utils libosmoctrl0 libosmoctrl-doc liborc-0.4-dev libpthread-workqueue-dev libpthread-stubs0-dev libvolk2-dev libvolk2.2

sudo ldconfig

Clone and build Gr-GSM:

git clone -b maint-3.8 https://github.com/velichkov/gr-gsm.git

cd gr-gsm

mkdir build

cd build

cmake ..

make -j$(nproc)

sudo make install

sudo ldconfig

sudo cp -r /usr/local/lib/python3/dist-packages/grgsm/ /usr/lib/python3/dist-packages/

Regards,

Al

Thanks Al,

Using gnuradio 3.8.5 from sources.
Can't use packages:(

Can you send me your grgsm_livemon?

TIA

Nikos,

I assumed you meant the grgsm_livemon script held at usr/local/bin/

Hopefully the attached helps.

I'm definitely not a coder, and only vaguely a computer dude; I am more of a cellular dude. I'll continue to try and help the community where I can add value.

Regards,

Al

[Nikos Balkanas]

Yup. Thanks a lot.
I am compiling now gnuradio 3.8.1. Hope this will work:)

[Nikos Balkanas]

Same problem with gnuradio 3.8.1...Flowgraph invalid:(
Also with gnuradio 3.8.1.0-rc. The version of the Ubuntu package.
Velikhof's fix was only for the package, not sources.
I will try to solve the volk issue in the main tree...

Nikos

[Nikos Balkanas]

I gave up, fixing the volk issue.
Thankfully your livemon works like a charm:)

Glad to hear it! Got to love frustrations when trying something different.
