PiHPSDR compile ubuntu
From HPSDRwiki
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:
dtparams=spi=on
and change to:
dtparams=spi=off
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
