Offf it's horrible. Developer doesn't believe in writing good instructions.
sudo apt-get install libx11-dev libportaudio2 subversion libftdi-dev libusb-1.0-0-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/libportaudio.so.2.0.0 /usr/lib/x86_64-linux-
gnu/libportaudio.so
# FUCKING SUBVERSION!!! IN 2023!!!
svn checkout https://svn.code.sf.net/p/linrad/code/trunk linrada
./configure --with-help
./configure --with-x11-64 --with-portaudio-64 --with-libftdi-64 --with-soft66-64 --with-rtlsdr-64
make xlinrad64
Then use https://qsl.net/ve7vv/Files/Linrad_installation_Guide.pdf
to understand how to set up the software.
Even after this, just delete the whole thing and install SDR++.
