Installing LimeSuite

Lime Suite needs to be built from source at a specific commit. Please follow these steps to do so:

cd ~
git clone https://github.com/myriadrf/LimeSuite.git
cd LimeSuite/
git checkout 28031bfcffe1e8fa393c7db88d4fe370fb4c67ea
mkdir buildir
cd buildir
cmake -G Ninja ..
ninja
sudo ninja install
sudo ldconfig

Getting the source code

cd ~
git clone --recurse-submodules git@github.com:Austrian-Broadcasting-Services/obeca-receive-process.git

cd obeca-receive-process

git submodule update

mkdir build && cd build

Build setup

cmake -DCMAKE_INSTALL_PREFIX=/usr -GNinja ..

Alternatively, to configure a debug build: cmake -DCMAKE_INSTALL_PREFIX=/usr -GNinja -DCMAKE_BUILD_TYPE=Debug ..

Building

ninja

Installing

sudo ninja install

The application installs a systemd unit and some helper scripts for setting up the TUN network interface and multicast routing.

Create a user named "ofr" for correct pre-configuration of receive process: sudo useradd ofr

To start the application as a background daemon: sudo systemctl start rp

To enable automatic start at each boot: sudo systemctl enable rp

Running the application manually

To set up networking and multicast routing, it's easiest to run the application though systemd once:

sudo systemctl start rp 
sudo systemctl stop rp

To allow the application to run at realtime scheduling without superuser privileges, set its capabilites accordingly. Alternatively, you can run it with superuser rights (sudo ./rp).

sudo setcap 'cap_sys_nice=eip' ./rp

After this, you can start rp manually from the build directory created in the prvious step, e.g.:

./rp -l 2

For available command line parameters, please see: ./rp --help
