MacOS

There are two main "package managers" used on MacOS: Homebrew and MacPorts. Trunk-recorder can be installed with dependencies from one or the other

Using Homebrew

Install Homebrew

See the Brew homepage for more information.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Install GNURadio and other dependencies

Install GNURadio, the OsmoSDR package for GNURadio, CMake, pkgconfig, cppunit, and openssl through Homebrew:

brew install gnuradio uhd gr-osmosdr cmake pkgconfig cppunit openssl fdk-aac-encoder sox

Note that you will need to provide the flag -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl to the invocation of cmake in the Build Instructions or you will receive an error from CMake about not finding libssl or a linking error from make about not having a library for -lssl:

cmake ../trunk-recorder -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl

Using MacPorts

These instructions should work on OS X 10.10, OS X 10.11, and macOS 10.12.

Install MacPorts

Follow the instructions from the MacPorts project to install the appropriate version of MacPorts for your version of macOS.

If you have already installed MacPorts, make sure your ports tree is up to date:

sudo port selfupdate

(7/24/21) Note: this has been tested and works on an M1 based Mac. Some dependencies for gr-osmosdr do not support ARM64 yet and can be removed by adding a -, eg: -docs

Install GNU Radio

The preferred method for installing GNU Radio on macOS is:

sudo port install gnuradio uhd gr-osmosdr

Install tools to compile Trunk Recorder

sudo port install cmake boost libusb cppunit

Install tools for OpenMHz

If you are interested in uploading recordings to OpenMHz, install FDK-AAC and Sox to convert the Wav files to M4a.

sudo port install sox

Download and make libfdk-aac.

1) extract the source, and cd to the source directory
2) autoreconf -i
3) ./configure
4) make
5) sudo make install

Download and make the command line fdkaac program.

1) extract the source, and cd to the source directory
2) autoreconf -i
3) ./configure
4) make
5) sudo make install

Configuring Trunk Recorder

The next step is to configure Trunk Recorder for the system you are trying to capture.

Running trunk recorder.

If all goes well you should now have the executable named trunk-recorder, and created the config.json configuration file as described in the Wiki and README.

From your build directory (e.g. trunk-build) you can now run ./trunk-recorder

Runtime options

Trunk Recorder will look for a config.json file in the same directory as it is being run in. You can point it to a different config file by using the --config argument on the command line, for example: ./trunk-recorder --config=examples/config-wmata-rtl.json.
