Software prerequisites include GNU Radio 3.7; also cmake; as well as the current list of
build packages listed on the build instructions page
http://op25.osmocom.org/trac/wiki.png/wiki/BuildInstructionsPage
Once this is done and the tar.gz file has been downloaded and unpacked from
http://mattrobert.com/Wireless/op25-gr3.7-0.01.tar.gzThe two subdirectories, gr-op25 and
gr-op25_repeater must be built as follows
cd ......./gr-op25
mkdir build
cd build
cmake ../
make
sudo make install
[repeat the above commands for gr-op25_repeater]
cd ......./gr-op25_repeater
mkdir build
cd build
cmake ../
make
sudo make install
