Linux Packages

We provide binary packages for several Linux distributions using the openSUSE Build Service. Please follow the linked installation guides below or alternatively visit our OBS project homepage: https://build.opensuse.org/package/show/devel:libraries:caf/caf

package description link
caf binaries only stable nightly
caf-devel binaries and headers stable nightly

FreeBSD Ports

We maintain a port for CAF, which you can install as follows:

pkg install caf

Alternatively, you can go to /usr/ports/devel/caf and tweak a few configuration options before installing the port:

make config
make install clean


You can install the latest stable release with:

brew install caf

Alternatively, you can use the development branch by using:

brew install caf --HEAD

Build CAF from Source

The easiest way to build CAF is to use the configure script. Other available options are using CMake directly or SNocs.

Using the configure Script

The script is a convenient frontend for CMake. See configure -h for a list of available options or read the [online documentation] (https://github.com/actor-framework/actor-framework/wiki/Configure-Options).

make test
make install [as root, optional]

Using CMake

All available CMake variables are available online. CAF also can be included as CMake submodule or added as dependency to other CMake-based projects using the file cmake/FindCAF.cmake.

Using SNocs

A SNocs workspace is provided by GitHub user osblinnikov and documented online.
