Install OpenCV 2.4.2 with ffmpeg support in Mac OS X 10.8

In order to install OpenCV 2.4.2 with ffmpeg support we have to first install lamemp3, faac, faad and of course ffmpeg. I’ve added a new script in my installation-scripts repository in Github but I’m going to write down here installing one by one all the libraries.

Also remember that you need to install the “Command Line Tools” in order to compile from the command line if you are using Xcode 4.4 or above. Have a look at “Can’t configure with cmake in Mac OS X 10.8” before continuing the installation process.

mp3lame:

$ curl -L -o lame-3.99.5.tar.gz http://sourceforge.net/projects/lame/files/lame/3.99/lame-3.99.5.tar.gz/download
$ tar xzvf lame-3.99.5.tar.gz
$ cd lame-3.99.5
$ ./configure --disable-dependency-tracking CFLAGS="-arch i386 -arch x86_64" LDFLAGS="-arch i386 -arch x86_64"
$ make
$ sudo make install
$ cd ..

faac (notice that only compiles for x86_64):

$ curl -L -o faac-1.28.tar.gz http://sourceforge.net/projects/faac/files/faac-src/faac-1.28/faac-1.28.tar.gz/download
$ tar xzvf faac-1.28.tar.gz
$ cd faac-1.28
$ ./configure --disable-dependency-tracking CFLAGS="-arch x86_64" LDFLAGS="-arch x86_64"
$ make
$ sudo make install
$ cd ..

faad:

$ curl -L -o faad2-2.7.tar.gz http://sourceforge.net/projects/faac/files/faad2-src/faad2-2.7/faad2-2.7.tar.gz/download
$ tar xvzf faad2-2.7.tar.gz
$ cd faad2-2.7
$ ./configure --disable-dependency-tracking CFLAGS="-arch i386 -arch x86_64" LDFLAGS="-arch i386 -arch x86_64"
$ make
$ sudo make install
$ cd ..

ffmpeg:

$ curl -O http://ffmpeg.org/releases/ffmpeg-0.11.5.tar.gz
$ tar xzvf ffmpeg-0.11.5.tar.gz
$ cd ffmpeg-0.11.5
$ ./configure --enable-libmp3lame --enable-libfaac --enable-nonfree --enable-shared --enable-pic --disable-mmx --arch=x86_64
$ make
$ sudo make install
$ cd ..

OpenCV 2.4.2:

$ curl -L -o OpenCV-2.4.2.tar.bz2 http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.2/OpenCV-2.4.2.tar.bz2/download
$ tar xvzf OpenCV-2.4.2.tar.bz2
$ cd OpenCV-2.4.2

If we configure and compile OpenCV 2.4.2 as it comes we will get a linker error at about 34% of the compilation process like this:

To solve this problem we have to change modules/highgui/CMakeLists.txt and add just before if(HAVE_FFMPEG) (on line 158) the following text:

if(APPLE)
  list(APPEND HIGHGUI_LIBRARIES ${BZIP2_LIBRARIES} -lmp3lame -lfaac -lbz2)
endif(APPLE)

Or we could apply this patch to OpenCV 2.4.2:

--- modules/highgui/CMakeLists.txt.old  2012-07-27 15:46:52.000000000 +0200

Now we can configure, compile and install it as usual. If you want to know more configuration options of cmake for OpenCV you can have a look at “Install OpenCV 2.3.1a in Mac OS X 10.6“.

$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ cd ..

Can’t configure with cmake in Mac OS X 10.8 and Xcode 4.4

I just did a clean install of Mac OS X 10.8 Mountain Lion and Xcode 4.4 so when I was ready to compile (again…) OpenCV 2.4.2 I got this error executing “cmake ..”:

$ cmake ..
CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

-- Configuring incomplete, errors occurred!

New versions of Xcode (4.4 and above) don’t install themselves in /Developer so I thought it could be a path issue, but the real problem is that the terminal utilities are not included in the normal install of Xcode anymore. You can install them and agree ther terms from the command line:

sudo xcode-select --install
sudo xcodebuild -license

Or download them separately from https://developer.apple.com/downloads/ (you need an Apple ID). Then look for the latest “Command Line Tools” for your system:

Install it and you will be able to compile from the terminal.
