PiHPSDR - Setting up and compiling on Ubuntu 20.10 64 bit

Install System Reqirements

sudo apt install -y build-essential git

Install piHPSDR prerequisites

sudo apt install libfftw3-dev libgtk-3-dev libasound2-dev libusb-1.0-0-dev libgpiod-dev libi2c-dev

Setup gpio group

Installing libi2c-dev creates a group i2c but installing libgpiod-dev does not create the gpio group.

sudo addgroup --system gpio
sudo adduser $USER gpio

Set gpio ownership and permissions on bootup

Create /etc/udev/rules.d/90-gpio.rules with:

KERNEL=="gpio*", OWNER="root", GROUP="gpio", MODE="660"

Disable SPI interface

Edit /boot/firmware/config.txt and find the line with:


and change to:


Reboot system

Reboot the system to have the gpio group changes and the SPI interface changes have effect.

Fetch WDSP and piHPSDR source code from github

I would recommend creating a directory github to download the source into:

mkdir github
cd github

Download the source:

git clone https://github.com/g0orx/wdsp.git
git clone https://github.com/g0orx/pihpsdr.git

Compile WDSP

cd ~/github/wdsp
make clean
make -j4
sudo make install

Copy libwdsp.so to the pihpsdr install directory:

cp libwdsp.so ~/github/pihpsdr/release/pihpsdr

Compile pihpsdr

cd ~/github/pihpsdr
make clean
make -j4
make release

Install pihpsdr

cd ~
tar xvf ~/github/pihpsdr/release/pihpsdr.tar
cd pihpsdr
sh ./install.sh
