acarsdec on the Radarcape

acarsdec is a software which uses a DVB-T stick in order to decode up to 4 channels ACARS signals within a 1MHz band segment.
The decoding process requires some mathematical functions and obtains plenty of processing resources. Due to that it is not guaranteed to run on a heavily loaded Radarcape and/or together with FR24 feeder. You may need to disable some features.

Installation requires some skills in handling a console but at the end is easy.

Prepare Installation

First, you need to install build tools on the Radarcape.

opkg update
opkg install packagegroup-core-buildessential
opkg install cmake
opkg install libusb-1.0-dev

This will take some time.

Install librtlsdr

Download one of the packaged releases: Look for the eventually greyed .tar.gz text, cut & paste the link of it and fetch it with wget on your Radarcape (in this case it is version 0.5.3, which was current while writing this descrition):

wget --no-check-certificate https://github.com/steve-m/librtlsdr/archive/v0.5.3.tar.gz

Untar/unpack it. Note that the filename eventually may differ for your download

tar xvf v0.5.3.tar.gz

As described here, navigate to ' Building with cmake: ' and follow these steps. You don't need sudo, as you are already root user on your Radarcape. The first command 'cd' must be adopted to what you have got as folder when unpacking your archive in the latest step.

cd librtlsdr-0.5.3
mkdir build
cd build
cmake ../
make
make install
ldconfig
