## Get CAF

### 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][obs]     [nightly][obs-nightly]
caf-devel | binaries and headers | [stable][obs-dev] [nightly][obs-dev-nightly]


### FreeBSD Ports

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

```sh
pkg install caf
```

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

```sh
make config
make install clean
```

### Homebrew

You can install the latest stable release with:

```sh
brew install caf
```

Alternatively, you can use the development branch by using:

```sh
brew install caf --HEAD
```

## Get the Sources

* git clone https://github.com/actor-framework/actor-framework.git
* cd actor-framework

## Build CAF from Source

The easiest way to build CAF is to use the `configure` script. Other available
options are using [CMake](http://www.cmake.org/) directly or
[SNocs](https://github.com/airutech/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).

```sh
./configure
make
make test
make install [as root, optional]
```

### Using CMake

All available CMake variables are available
[online](https://github.com/actor-framework/actor-framework/wiki/CMake-Options).
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](https://github.com/osblinnikov) and documented
[online](https://github.com/actor-framework/actor-framework/wiki/Using-SNocs).

## Dependencies

* CMake
* Pthread (until C++11 compilers support the new `thread_local` keyword)

## Supported Compilers

* GCC >= 4.8
* Clang >= 3.2

## Supported Operating Systems

* Linux
* Mac OS X
* FreeBSD 10
* *Note for MS Windows*: CAF relies on C++11 features such as variadic templates
  and unrestricted unions. We will support Visual Studio as soon as Microsoft's
  compiler implements all required C++11 features. In the meantime, you can
  use CAF via MinGW.
