## 5.5. Mac OS

MPlayer does not work on Mac OS versions before 10, but should compile out-of-the-box on Mac OS X 10.2 and up. The preferred compiler is the Apple version of GCC 3.x or later. You can get the basic compilation environment by installing Apple's Xcode. If you have Mac OS X 10.3.9 or later and QuickTime 7 you can use the `corevideo` video output driver.

Unfortunately, this basic environment will not allow you to take advantage of all the nice features of MPlayer. For instance, in order to have OSD support compiled in, you will need to have `fontconfig` and `freetype` libraries installed on your machine. Contrary to other Unixes such as most Linux and BSD variants, OS X does not have a package system that comes with the system.

There are at least two to choose from: Fink and MacPorts. Both of them provide about the same service (i.e. a lot of packages to choose from, dependency resolution, the ability to simply add/update/remove packages, etc...). Fink offers both precompiled binary packages or building everything from source, whereas MacPorts only offers building from source. The author of this guide chose MacPorts for the simple fact that its basic setup was more lightweight. Later examples will be based on MacPorts.

For instance, to compile MPlayer with OSD support:

    sudo port install pkg-config

This will install pkg-config, which is a system for managing library compile/link flags. MPlayer's `configure` script uses it to properly detect libraries. Then you can install fontconfig in a similar way:

    sudo port install fontconfig

Then you can proceed with launching MPlayer's `configure` script (note the `PKG_CONFIG_PATH` and `PATH` environment variables so that `configure` finds the libraries installed with MacPorts):

    PKG_CONFIG_PATH=/opt/local/lib/pkgconfig/ PATH=$PATH:/opt/local/bin/ ./configure

### 5.5.1. MPlayer OS X GUI

You can get a native GUI for MPlayer together with precompiled MPlayer binaries for Mac OS X from the MPlayerOSX project, but be warned: that project is not active anymore.

Fortunately, MPlayerOSX has been taken over by a member of the MPlayer team. Preview releases are available from our download page and an official release should arrive soon.

In order to build MPlayerOSX from source yourself, you need the `mplayerosx`, the `main` and a copy of the `main` SVN module named `main_noaltivec`. `mplayerosx` is the GUI frontend, `main` is MPlayer and `main_noaltivec` is MPlayer built without AltiVec support.

To check out SVN modules use:

    svn checkout svn://svn.mplayerhq.hu/mplayerosx/trunk/ mplayerosx
    svn checkout svn://svn.mplayerhq.hu/mplayer/trunk/ main

In order to build MPlayerOSX you will need to set up something like this:

    MPlayer_source_directory
       |
       |--->main           (MPlayer Subversion source)
       |
       |--->main_noaltivec (MPlayer Subversion source configured with --disable-altivec)
       |
       \--->mplayerosx     (MPlayer OS X Subversion source)

You first need to build main and main_noaltivec.

To begin with, in order to ensure maximum backwards compatibility, set an environment variable:

    export MACOSX_DEPLOYMENT_TARGET=10.3

Then, configure:

If you configure for a G4 or later CPU with AltiVec support, do as follows:

    ./configure --disable-gl --disable-x11

If you configure for a G3-powered machine without AltiVec, use:

    ./configure --disable-gl --disable-x11 --disable-altivec

You may need to edit `config.mak` and change `-mcpu` and `-mtune` from `74XX` to `G3`.

Continue with

    make

then go to the mplayerosx directory and type

    make dist

This will create a compressed `.dmg` archive with the ready to use binary.

You can also use the Xcode 2.1 project; the old project for Xcode 1.x does not work anymore.
