I am trying to setup my RSP2Pro on a system running Manjaro Linux by following the instructions in
https://www.sdrplay.com/docs/SDRplay_no ... s_Flow.pdf

Running SoapySDRUtil gives the following error:

Code: Select all

[dell5520 lib]# SoapySDRUtil --info
SoapySDRUtil: error while loading shared libraries: libSoapySDR.so.0.6: cannot open shared object file: No such file or directory

sudo ldconfig completes with no output.

As far as I can see the libraries are correctly created and placed in /usr/local/lib but SoapySDRUtil --info still gives the same "error while loading shared libraries: libSoapySDR.so.0.6: cannot open shared object file: No such file or directory" error.

uname -a gives:

Code: Select all

Linux dell5520 4.9.66-1-MANJARO #1 SMP PREEMPT Thu Nov 30 14:08:24 UTC 2017 x86_64 GNU/Linu

Have I made a schoolboy error in any of the above and if not what's going wrong please? The RSP2Pro works fine on Win7

Any suggestions welcome
Many thanks and festive greetings
Julian

use:

export LD_LIBRARY_PATH=/usr/local/lib

you can add it to your .bashrc file so that you don't have to keep doing it every time you start a terminal window.

Best regards,

ldd /usr/local/bin/SoapySDRUtil

should show what the exact location and name are where SoapySDRUtil expects the library.

On my system it gives:
