Hello Marcus, first of all, I hope that this email reaches you in good health. Thanks for your answer. I've tried to work as cautiously as possible, but it seems that I still have trouble installing gr-osmosdr. I hope that you can help me connecting the last dots.
I install GRC using the ppa: $ sudo add-apt-repository ppa:gnuradio/gnuradio-releases $ sudo apt-get update $ sudo apt install gnuradio I install LibbladeRF using the ppa: $ sudo add-apt-repository ppa:bladerf/bladerf $ sudo apt-get update $ sudo apt-get install bladerf $ sudo apt-get install libbladerf-dev Then I've installed two libraries for OsmoSDR: $ sudo apt update $ sudo apt install libosmosdr-dev $ sudo apt-get install librtlsdr-dev After this, it's time to follow the instructions on https://osmocom.org/projects/gr-osmosdr/wiki#Automated-installation For this, I've used cmake version 3.15.2. $ git clone git://git.osmocom.org/gr-osmosdr $ cd gr-osmosdr/ $ mkdir build $ cd build/ $ cmake ../ After this, I try to do: $ make $ sudo make install $ sudo ldconfig But this is where I meet my error: make[2]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/liborc-0.4.so', needed by 'lib/libgnuradio-osmosdr.so.0.2.0.0'. Stop. CmakeFiles/Makefile2:177: recipe for target 'lib/CMakeFiles/gnuradio-osmosdr.dir/all' failed make[1]:*** [lib/CMakeFiles/gnuradio-osmosdr.dir/all] Error 2 Makefile:140: recipe for target 'all' failed make: *** [all] Error 2 I've read that this means that '/usr/lib/x86_64-linux-gnu/liborc-0.4.so' is not found on my computer, which is indeed the case. In that folder, I do have the files: liborc-0.4.so.0 liborc-0.4.so.0.28.0 liborc-test-0.4.so.0 liborc-test-0.4.so.0.28.0 But not just the exact file that cmake searches for. I don't know much about these extensions, but I've read that this have something to do with version control. So I decided to do a simple hack, and copied liborc-0.4.so.0 to a new file with the expected name: $ cd /usr/lib/x86_64-linux-gnu/ $ sudo cp liborc-0.4.so.0 liborc-0.4.so When I go back to the previous terminal, it is found that 'make' does not provide any errors anymore, and 'make install' and 'ldconfig' also work. And when I open GRC, I can find the Osmocom source and sink blocks, which are the ones that I need. So that's good. BUT when I run my GRC flowchart, I get a python error: ModuleNotFoundError: No module named 'osmosdr' I've spent some time trying to solve this, but I'm not getting any further. I guess that my little hack of renaming liborc was problematic, but then I wouldn't know where to find the original file. Did I make some mistakes in installing any of the libraries? Do I have to use other files or commands? Am I missing libraries that I should install? I hope you can find the time to help me with this issue. Thanks in advance for your help. Jerom Maas PS When I do "$ cmake ../", 'Python Support' is listed as one of the Gnuradio enabled components, so I would assume that all the python libraries should be installed? PPS @ Fernando: I just receive your enquiry as I'm typing this mail. Yes, I have been able to connect everything to a GRC3.7, in Linux and even in Windows. Unfortunately, I can't recall which exact steps I took for that as it was years ago. Right now, I need to get it running in GRC 3.8, but as you can read from this mail... yet unsuccesful. At least I hope that my description of the Linux Commands is useful for you - but remember that it's not working yet! ________________________________ Van: Müller, Marcus (CEL) <muel...@kit.edu> Verzonden: vrijdag 6 maart 2020 13:12:04 Aan: discuss-gnuradio@gnu.org; Jerom Maas - LR Onderwerp: Re: BladeRF 2 in GRC3.8 Haven't tried it, but I don't see why not. Make sure you've got the right bladerf library development headers installed before building gr- osmosdr.
