This is an '''howto''' to compile {{VLC}} on ''Mac OS X'', focused on '''VLC 2.0''' and newer. 

= Pre-requisites  =

=== Apple Software ===

*You need at least MacOSX '''10.7''', '''Lion''' or later is strongly recommended, though. 
*'''Developer Tools from Apple''' from http://developer.apple.com/technology/xcode.html<br> You need at least ''Xcode4.3''. <br />Note: If using [https://developer.apple.com/library/mac/#documentation/DeveloperTools/Conceptual/WhatsNewXcode/Articles/xcode_4_3.html Xcode 4.3], the command line tools must be installed manually through preferences.

=== Xcode select on Xcode 4.3  ===

If you are on Xcode 4.3 with no previous Xcode installation , you probably need to run xcode select to point to your xcode developer directory.

 xcrun clang

If this outputs 'Error: No developer directory...', then use xcode-select to select the developer directory within the Xcode package.

something like:

 sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer  

=== Configure the environment ===

On '''Mac OS X 10.7''' VLC needs to be compiled using Apple's clang compiler in its latest version. To use this compiler, you need to export the respective variables. In a Bourne Shell, type this (if Xcode is installed to its default location; bash is the default shell on OS X): 

 export CC="xcrun clang"
 export CXX="xcrun clang++"
 export OBJC="xcrun clang"

If you are using a C-Shell, you need to use the setenv command of course.

= [[GetTheSource|Get the source code]]  =

  git clone git://git.videolan.org/vlc.git

= Build VLC with a single command  =

Setup a build folder:
 cd vlc && mkdir build && cd build

And run the build:
 ../extras/package/macosx/build.sh

Wait and you are finished

You can see more options for this build (change arch or sdk):
 ../extras/package/macosx/build.sh -h

= Build steps =
Now, if you prefer, you can read the following detailed information on how the build internally works:

== Additional development tools  ==

You need development tools, notably all the autotools, to build VLC correctly.
 
Here is how:
 cd vlc/extras/tools
 ./bootstrap && make
 cd ../..

'''Important''': set the new PATH.
 export PATH=$PWD/extras/tools/build/bin:$PATH

== SDK selection ==

Set the OSX_Version to your current OSX Version

 export OSX_VERSION=10.7

== Prepare [[Contrib Status|3rd party libraries]]  ==

Before compiling VLC, you need lots of other libraries. Here is how to get them: 

 cd contrib
 mkdir -p osx &amp;&amp; cd osx
 ../bootstrap --host=x86_64-apple-darwin10 --build=x86_64-apple-darwin10

=== Prebuilt libraries (recommended) ===

If you want to download a prebuilt package of all the needed libraries. 

You need to download "x264-git.tar.gz" from "http://download.videolan.org/contrib/" and copy it to "vlc/contrib/tarballs".

 make prebuilt

After:

You need to little change on "x265.pc" file:

 vim vlc/contrib/x86_64-apple-darwin10/lib/pkgconfig/x265.pc
 --Libs:  -L${libdir} -lx265  -lstdc++ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/'''4.2'''/lib/darwin/libclang_rt.osx.a
 ++Libs:  -L${libdir} -lx265  -lstdc++ /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/'''[your version]'''/lib/darwin/libclang_rt.osx.a

Important thing is '''[your version]'''. Go to "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/" folder and find your version.

And then skip to [[OSXCompile#Bootstrap_VLC|bootstrap section of this page]].

=== Build your own libraries (not for the faint-hearted) ===

If you want to build from source a package in the contribs: 

 make -j4 .gettext
 export PATH=$PWD/../x86_64-apple-darwin10/bin:$PATH

Then: 

 make -j4

If you had no errors, the 3rd party libraries (contrib) are built correctly and you can proceed to the next step.

=== Go Back  ===

Go back to the VLC source directory: 

 cd ../..

== Bootstrap VLC  ==

This will create the configure script: 

 ./bootstrap

== Configure the VLC build  ==

Create a build folder: 

 mkdir -p build &amp;&amp; cd build

To list the different options of configure: 

 ../extras/package/macosx/configure.sh --help

To build a binary with the previously installed x86_64-apple-darwin10 contrib: 

 ../extras/package/macosx/configure.sh --enable-debug --host=x86_64-apple-darwin10 --build=x86_64-apple-darwin10

== Build VLC  ==

Just do:
 make -j4

and wait...

if you want to avoid recompiling VLC.app every time during development use

 make VLC-dev.app

== Package VLC Application for Mac  ==

If you want a disk-image: 

 make package-macosx

== Sign VLC Application for Mac  ==

If you want to sign your application with a certificate, for example for Gatekeeper, you need to run:

 extras/package/macosx/codesign.sh -i "certificate name"

= What's wrong: troubleshooting  =

== 3rd party packagers and PATH  ==

'''Pay careful attention to remove any reference to 3rd party package managersfrom your environment.''' This is important to avoid conflicts between your package manager (homebrew, fink, macports...) and the contrib package manager we use to build our contrib. 

It shouldn't be necessary, but it can happen. 

'''git must still be accessible though!''' 

 unset PKG_CONFIG_PATH
 unset PKG_CONFIG_LIBDIR
 export PATH=$PWD/build/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin
