SdrGlut is a simple software defined radio player. Using glut for drawing and glui for its dialogs makes it tiny compared to programs that use QT5 or wxWidgets. SdrGlut uses liquid-sdr and SoapySDR to preform the SDR calculations. The audio is handled by OpenAL and RtAudio. iqSDR has much overlap with SdrGlut, but now it is getting its own new capibilities.

Installation of RtAudio

The lastest version of SdrGlut needs to have RtAudio installed. Here are videos showing how to do the install on various systems. The Raspberry Pi can follows the instructions that were given for Ubuntu 18.04.

Video of RtAudio installation on:

• MacOS
• Windows 10
• Ubuntu18.04
• Raspberry pi
• Ubuntu22.04

Problems With libliquid

There are recent versions of libliquid that have the same version number and need different function calls. In MainSource/firstFile.h the defines -

#define LIQUID_VERSION_4 1

#define WINDOWS_LONG_NAMES 1

can to be turned on or off as needed. The LIQUID_VERSION_NUMBER logic works correctly about 80 percent of the time.

Installation steps on Ubuntu 22.04

In the file "MainSource/firstFile.h" comment out the line -

//#define WINDOWS_LONG_NAMES 1

Then -

bash
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential
sudo apt-get install libsoapysdr-dev
sudo apt-get install libopenal-dev
sudo apt-get install libliquid-dev
sudo apt-get install freeglut3-dev
sudo apt-get install libalut-dev
sudo apt-get install librtaudio-dev
sudo apt-get install git
cd ~/Desktop
git clone --depth=1 https//github.com/righthalfplane/SdrGlut.git
cd SdrGlut
make -f makefileUbunta -j 4
./sdrglut.x

Install on Raspberry pi

SdrGlut runs nicely on the Raspberry pi 4 - Do not know if slower version have enough horsepower for it

To do the normal edition of Raspbian - follow the uBuntu instructions with -

make -f makefileRaspbian

instead of

make -f makefileUbunta

The SDRPlay Edition

This is what I did to get SdrGlut running on the SDRPlay verison of Raspbian.

The SDRPlay verison Raspbian has the SDRPlay libraries already installed.

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install build-essential

sudo apt-get install libopenal-dev

sudo apt-get install libliquid-dev

sudo apt-get install freeglut3

sudo apt-get install freeglut3-dev

sudo apt-get install libalut0

sudo apt-get install libalut-dev

sudo apt-get install git

cd ~/Desktop

git clone https://github.com/righthalfplane/SdrGlut.git

cd SdrGlut

make -f makefileRaspbian

./sdrglut.x

added support for NetSDR -

cd ~/Desktop

git clone https://github.com/pothosware/SoapyNetSDR.git

cd SoapyNetSDR

added support for NetSDR -

cd ~/Desktop

git clone https://github.com/pothosware/SoapyNetSDR.git

cd SoapyNetSDR

mkidr build

cd build

cmake ../

make -j 4

sudo make install

added support for SDRPlay -

Get the sdrplay driver installer and install it -

https://www.sdrplay.com/downloads/

SDRplay_RSP_API-MacOSX-3.07.3.pkg

Install SdrGlut on Windows 7 and Windows 10

Install RtAudio

See - above

Install OpenAL -

OpenAL must be loaded on to window. Get the two packages -

OpenAL1.1.CoreSDK

OpenAL 1.1 windows install

from "https://www.openal.org/downloads"

and install them.

Install PothosSDR and SdrGlut -

The easiest way to install SdrGlut is to install the PothosSDR package first -

https://downloads.myriadrf.org/builds/PothosSDR/

Run PothosSDR-2021.07.25-vc16-x64.exe and select

add PothosSDR to system path for all users

full install

git clone https://github.com/righthalfplane/SdrGlut.git

Then use the GUI and go to the directory SdrGlut/Sdrglut-windows and click the project SdrGlut.sln.

Select "Release" and "X64" -

Then select "Start without Debugging", SdrGlut should compile and start running.
