- 4 Build steps
- 4.1 Additional development tools
- 4.2 SDK selection and 32/64 bits
- 4.3 Prepare 3rd party libraries
- 4.4 Bootstrap VLC
- 4.5 Configure the VLC build
- 4.6 Build VLC
- 4.7 Package VLC Application for Mac
- 4.8 Sign VLC Application for Mac
- 5 What's wrong: troubleshooting
- You need at least MacOSX 10.5. 10.6, Snow Leopard or later is strongly recommended, though.
- Developer Tools from Apple from http://developer.apple.com/technology/xcode.html
Both Xcode3 and Xcode4 should be fine.
Note: If using Xcode 4.3 or later, the command line tools must be installed manually through preferences. Additionally, Xcode 4.3 will require changes to VLC's build system which are currently pending and may require patching until resolved.
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.
If this outputs 'Error: No developer directory...', then use xcode-select to select the developer directory within the Xcode package.
sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer
If you have XCode 4, Git is already installed You just need to point your Terminal to it:
If you have Xcode 3, get Git from their website.
Configure the environment
On Mac OS X 10.6 VLC needs to be compiled using Apple's llvm-gcc-4.2 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=/Developer/usr/bin/llvm-gcc-4.2 export CXX=/Developer/usr/bin/llvm-g++-4.2 export OBJC=/Developer/usr/bin/llvm-gcc-4.2
On Mac OSX 10.8.2 use the following
export CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc export CXX=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/c++ export OBJC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/cc
If you are using a C-Shell, you need to use the setenv command of course.
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:
Wait and you are finished
You can see more options for this build (change arch or sdk):
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.
SDK selection and 32/64 bits
If you want to use the 10.6 SDK (your VLC will only run on 10.6 and more recent computers):
You can do the same for 10.5, but please check that you have MacOSX10.5.sdk installed in /Developer/SDKs/ . If you are using Xcode 4.2, you can install the 10.5 sdk with the .dmg from Xcode3.
The instructions below will build a 64 bits binary using 10.6 (Snow Leopard) SDK. This is reflected by using host and build variables x86_64-apple-darwin10.
This "triplet" is ARCHITECTURE-apple-SYSTEM.
x86_64represents Intel 64bits.
i686represents Intel 32bits.
powerpcrepresents PowerPC 32bits.
darwin9represents MacOSX 10.5.
darwin10represents MacOSX 10.6.
So to make a PowerPC build, you would use powerpc-apple-darwin9. So to make a intel32 build for 10.5+, you would use i686-apple-darwin9. So to make a intel64 build for 10.6+, you would use x86_64-apple-darwin10.
Prepare 3rd party libraries
Before compiling VLC, you need lots of other libraries. Here is how to get them:
cd contrib mkdir -p osx && 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.
And then skip to 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
If you had no errors, the 3rd party libraries (contrib) are built correctly and you can proceed to the next step.
Go back to the VLC source directory:
This will create the configure script:
Configure the VLC build
Create a build folder:
mkdir -p build && cd build
To list the different options of configure:
To build a 64 bits binary:
../extras/package/macosx/configure.sh --enable-debug --host=x86_64-apple-darwin10 --build=x86_64-apple-darwin10
Package VLC Application for Mac
If you want to share the application with another user or another computer:
If you want a disk-image:
make package-macosx-plugin for the Safari/Mozilla plugin.
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"
If you want to support OS X Snow Leopard and Leopard with your signature, you need to enable the "-g" option. Note that you need to replace the signature leaf hash "75GAHG3SZQ" with your own inside the codesign script prior to doing so, since otherwise your certificate will mix with VideoLAN's and your binary will be rejected by the OS.
What's wrong: troubleshooting
Starting with Leopard, Xcode may be installed to a custom location on the administrator's choice. While this is non-problematic for ordinary Xcode projects, VLC needs a little help. You have to place extra symbolic links in /Developer pointing to your custom location for these folders:
usr, Headers, Private, SDKs, Tools, Makefiles
You can easily create these links by executing the following command for each folder (whereas theFolder is one of these six):
ln -s /full/path/to/Developer/theFolder /Developer/theFolder
Please make sure that you are using the latest Xcode3 or the latest version of Xcode4 to compile VLC
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
QTsound compilation on X.5
MacOS X.5.SDK is broken - 2 options exist:
- Download the MacOS10.6.sdk and get QTCaptureDecompressedAudioOutput.h from /Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/QTKit.framework/Headers/ and move it to /Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/QTKit.framework/Headers/
- Edit /Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/QTKit.framework/Headers/QTKit.h and add the
#import <QTKit/QTCaptureDecompressedAudioOutput.h> where needed.
- Configure the VLC build to explicitly use the MacOS10.6.sdk by adding the following flag:
Cross-Compilation to PPC from X.6 intel
If you want to compile VLC for PPC, based on a X.6 intel, you need to tweak a few things since Apple broke it.
This is VERY advanced stuff!
Be sure to:
- have X.6.8
- Xcode 4.2 installed in the normal /Developers location
- Xcode 3 installed in /Xcode3 location
- MacOS X.6 and X.5 SDK installed in /Developers/SDKs/ , as explained above (SDK selection).
Using this out of the box will not work because AS for ppc is broken on the default setup. Here is how to fix it:
cd /usr/libexec/as sudo mkdir ppc cd ppc sudo ln -sf /Xcode3/usr/bin/as as
