Installing GQRX and SDR++ on RaspberryPi

 Installing GQRX and SDR++ on RaspberryPi

These are all the steps I actually performed.

sudo apt update
apt list --upgradable
sudo apt install gqrx-sdr
rtl_test -t
gqrx

So GQRX sort of worked...

So SDR++

Grab the source
git clone https://github.com/AlexandreRouma/SDRPlusPlus.git
ls
cd SDRPlusPlus
mkdir build
cd build/
cmake ..

so erroring as missing these packages....fftw3 glfw glew libvolk

so to install them...
sudo apt-get install freeglut3
sudo apt-get install freeglut3-dev
cmake ..
sudo apt install libglew-dev
cmake ..
sudo apt install glfw3
sudo apt install libglfw3-dev
cmake ..
sudo apt install libairspy-dev
cmake ..
sudo apt install libairspyhf-dev
cmake ..
sudo apt install libhackrf-dev
cmake ..
sudo apt install libsoapysdr-dev
cmake ..

libiio missing....so get that compile and install

cd
git clone https://github.com/analogdevicesinc/libiio.git
cd libiio/
cmake ./
See what errors are (there were some)
cat /home/pi/libiio/CMakeFiles/CMakeOutput.log

install more prerequisites some were already there so it ignores them (from an SDR pluto install doc)
sudo apt-get install libxml2 libxml2-dev bison flex libcdk5-dev cmake
sudo apt-get install libaio-dev libusb-1.0-0-dev libserialport-dev libxml2-dev libavahi-client-dev doxygen graphviz

Try the libiio build again
cmake ./
make all
sudo make install
Add the path bit
PATH=/usr/lib/:$PATH
check it is working iio_info

go back to SDR _++ again
cd ..
cd SDRPlusPlus/
cd build/
cmake ..

so more missing get and install them

cd
git clone https://github.com/analogdevicesinc/libad9361-iio.git
cd libad9361-iio
cmake ./
make
sudo make install
cd ~/SDRPlusPlus/build/
cmake ..

still more missing

wget http://www.music.mcgill.ca/~gary/rtaudio/release/rtaudio-5.1.0.tar.gz
mv rtaudio-5.1.0.tar.gz ~/Downloads/
cd
cd Downloads/
tar -zxvf rtaudio-5.1.0.tar.gz
cd rtaudio-5.1.0/
mkdir build && cd build
cmake ../
make
sudo make install

Back to SDR++
cd
cd SDRPlusPlus/build/
cmake ..
this time no errors
used N=4 as 4 cpu make -j 4
It maxed out the CPU for a few mins
sudo make install

That's it SDR++ and GQRX both installed

 

Yes I am sure much of the missing bits were listed in the prerequisties docs of both but we all read those don't we :-) Of course I had added the development environment to it as well. Mine has 128GB SD card (high endurance) and has a 3TB SSD attached which takes and stores backups, snapshots etc I use an adaptor as well so I don't have to insert the MiniSD card into the Pi.
