gqrx and perseus-sdr on linux mint 20.1 cinnamon

[Karli Ist Da]

Hi everybody,                                    16.April 2021

I am new here and in linux as well. I run a laptop linux mint 20.1 cinnamon

and want to use my perseus-sdr with gqrx.

I have done the advices of andrea montefusco:

to build the gr-osmosdr specific for Perseus:

sudo apt install cmake

wget http://github.com/IW0HDV/gr-osmosdr/archive/perseus.zip

unzip perseus.zip

cd gr-osmosdr-perseus

mkdir build

cd build/

cmake ../ && make && sudo make install && sudo ldconfig

after done this, starting again gqrx, and pressing "Configure I/O device", the option for Perseus will appear in the device's list.

BUT... perseus option does NOT appear in my Configure device pulldown.

PLEASE help me, I have no idea what to do now.

And by the way, I am a linux newbie as well.

Thanks a lot, Karl
