#Build Snapcast
Clone the Snapcast repository. To do this, you need git.  
For Debian derivates (e.g. Raspbian, Debian, Ubuntu, Mint):

    $ sudo apt-get install git

For Arch derivates:

    $ pacman -S git

For FreeBSD:

    $ sudo pkg install git

Clone Snapcast:

    $ git clone https://github.com/badaix/snapcast.git

this creates a directory `snapcast`, in the following referred to as `<snapcast dir>`.  
Next clone the external submodules:

    $ cd <snapcast dir>/externals
    $ git submodule update --init --recursive


##Linux (Native)
Install the build tools and required libs:  
For Debian derivates (e.g. Raspbian, Debian, Ubuntu, Mint):

    $ sudo apt-get install build-essential
    $ sudo apt-get install libasound2-dev libvorbisidec-dev libvorbis-dev libflac-dev alsa-utils libavahi-client-dev avahi-daemon

Compilation requires gcc 4.8 or higher, so it's highly recommended to use Debian (Respbian) Jessie.

For Arch derivates:

    $ pacman -S base-devel
    $ pacman -S alsa-lib avahi libvorbis flac alsa-utils

###Build Snapclient and Snapserver
`cd` into the Snapcast src-root directory:

    $ cd <snapcast dir>
    $ make

Install Snapclient and/or Snapserver:

    $ sudo make installserver
    $ sudo make installclient

This will copy the client and/or server binary to `/usr/sbin` and update init.d/systemd to start the client/server as a daemon.

###Build Snapclient
`cd` into the Snapclient src-root directory:

    $ cd <snapcast dir>/client
    $ make

Install Snapclient

    $ sudo make install

This will copy the client binary to `/usr/sbin` and update init.d/systemd to start the client as a daemon.

###Build Snapserver
`cd` into the Snapserver src-root directory:

    $ cd <snapcast dir>/server
    $ make

Install Snapserver

    $ sudo make install

This will copy the server binary to `/usr/sbin` and update init.d/systemd to start the server as a daemon.


##FreeBSD (Native)
Install the build tools and required libs:  

    $ sudo pkg install gmake gcc bash avahi libogg libvorbis flac

###Build Snapserver
`cd` into the Snapserver src-root directory:

    $ cd <snapcast dir>/server
    $ gmake TARGET=FREEBSD

Install Snapserver

    $ sudo gmake TARGET=FREEBSD install

This will copy the server binary to `/usr/local/sbin` and the startup script to `/usr/local/etc/rc.d/snapserver`. To enable the Snapserver, add this line to `/etc/rc.conf`: 

    snapserver_enable="YES"

For additional command line arguments, add in `/etc/rc.conf`:

    snapserver_opts="<your custom options>"

Start and stop the server with `sudo service snapserver start` and `sudo service snapserver stop`.

##macOS (Native)

*Warning: macOS support is experimental*

Install Xcode from the App Store  

###Build Snapclient
Install the required libs:  

    $ brew install flac libvorbis

`cd` into the Snapclient src-root directory:

    $ cd <snapcast dir>/client
    $ make TARGET=MACOS

##Android (Cross compile)
Cross compilation for Android is done with the [Android NDK](http://developer.android.com/tools/sdk/ndk/index.html) on a Linux host machine.  

###Android NDK setup
http://developer.android.com/ndk/guides/standalone_toolchain.html
 1. Download NDK: `http://dl.google.com/android/repository/android-ndk-r12b-linux-x86_64.zip`
 2. Extract to: `/SOME/LOCAL/PATH/android-ndk-r12b`
 3. Setup toolchain somewhere in your home dir (`<android-ndk dir>`):

````
$ cd /SOME/LOCAL/PATH/android-ndk-r10e/build/tools
$ ./make-standalone-toolchain.sh --arch=arm --platform=android-14 --install-dir=<android-ndk dir> --ndk-dir=/SOME/LOCAL/PATH/android-ndk-r12b
````

###Build Snapclient
Edit the first lines in `<snapcast dir>/client/build_android.sh` and in `<snapcast dir>/externals/build_externals_android.sh` to let `NDK_DIR` point to your `<android-ndk dir>`  
Cross compile and install FLAC, ogg, and tremor (only needed once):

    $ cd <snapcast dir>/externals
    $ ./build_externals_android.sh
   
Compile the Snapclient:

    $ cd <snapcast dir>/client
    $ ./build_android.sh

The binaries for `armeabi` and `armeabi-v7a` will be copied into the Android's assets directory (`<snapcast dir>/android/Snapcast/src/main/assets/bin/`) and will be part of the Snapcast App.


##OpenWrt (Cross compile)
Cross compilation for OpenWrt is done with the [OpenWrt build system](https://wiki.openwrt.org/about/toolchain) on a Linux host machine.  
https://wiki.openwrt.org/doc/howto/build

###OpenWrt build system setup
https://wiki.openwrt.org/doc/howto/buildroot.exigence

Clone OpenWrt to some place in your home directory (`<buildroot dir>`)

    $ git clone git://git.openwrt.org/15.05/openwrt.git

Download and install available feeds

    $ cd <buildroot dir>
    $ ./scripts/feeds update -a
    $ ./scripts/feeds install -a

Build

    $ make menuconfig
    $ make

Within the OpenWrt directory create symbolic links to the Snapcast source directory and to the OpenWrt Makefile:

    $ cd <buildroot dir>/package/sxx/snapcast
    $ ln -s <snapcast dir>/openWrt/Makefile.openwrt Makefile
    $ ln -s <snapcast dir> src

Build Snapcast:

    $ cd <buildroot dir>
    $ make package/sxx/snapcast/clean V=s
    $ make package/sxx/snapcast/compile -j1 V=s

The packaged `ipk` files are in `<buildroot dir>/bin/ar71xx/packages/base/snap[client|server]_0.6.0_ar71xx.ipk`
