CAF is an open source implementation of the actor model for C++ featuring lightweight & fast actor implementations, pattern matching for messages, network transparent messaging, and more.

We do not officially maintain packages for CAF. However, some of our community members made packages available for these package managers:
git clone https://github.com/actor-framework/actor-framework.git
cd actor-frameworkCAF uses CMake as its build system of choice. To make
building CAF more convenient from the command line, we provide a configure
script that wraps the CMake invocation. The script only works on UNIX systems.
On Windows, we recommend generating an MSVC project file via CMake for native
builds.
The script is a convenient frontend for CMake. See configure -h for a list
of available options. By default, the script creates a build directory and
asks CMake to generate a Makefile. A build with default settings generally
follows these steps:
./configure
cd build
make
make test [optional]
make install [as root, optional]To generate a Makefile for building CAF with default settings, either use a CMake GUI or perform these steps on the command line:
mkdir build
cd build
cmake ..After this step, cmake -LH prints the most useful configuration options for
CAF, their default value, and a helptext.
Other CMake projects can add CAF as a dependency by using find_package and
listing the required modules (e.g., core or io) . When installing CAF to a
non-standard location, set CAF_ROOT prior to calling find_package.

- OpenSSL (only when building the OpenSSL module)
C++ is an evolving language. Compiler vendors constantly add more language and standard library features. Since CAF runs on many platforms, this means we need a policy that on the one hand ensures that we only use a widely supported subset of C++ and on the other hand that we naturally progress with the shifting landscape to eventually catch up to more recent C++ additions (in order to not "get stuck").
So instead of singling out individual compiler versions, we build CAF for each commit on all platforms that we currently deem relevant. Everything that passes our CI is "fair game".
Our CI covers Windows (latest MSVC release), macOS (latest Xcode release), FreeBSD (latest) and several Linux distributions (via the Docker images found here). For Linux, we aim to support the current releases (that still receive active support) for the major distributions. Note that we do not build on Linux distributions with rolling releases, because they generally provide more recent build tools than distributions with traditional release schedules and thus would only add redundancy.
- Building an offline version of the manual requires
Sphinx:
cd manual sphinx-build . html
- Building an offline version of the API reference documentation requires
Doxygen (simply run the
doxygencommand at the root directory of the repository).
