Build OpenCV JDK 6 32 bit for Mac

This problem returned me 2 days in a row, and at that moment I was very desperate. As stated in the description of the question, I need a 32-bit version of the OpenCV 2.4.11 Java library, which will work with JDK 1.6 on a Mac running Yosemite.

I need this because another library that I use requires 32 bits ( and this is only available in JDK 1.6 ). Therefore, I use JDK 1.6 and pass the VM argument -d32.

I had two main attempts:

For both attempts, I first set my default JDK to 6:

$nano .bash_profile //Opening the Bash Profile
export JAVA_HOME=$(/usr/libexec/java_home -v 1.6) //Set Java_Home to JDK 1.6

(It should be noted that both methods below have no problems building a library with JDK 1.7 and 64 bits.)

Method 1: I am trying to create an OpenCV library using CMake:

I go to the directory where I saved the library
mkdir build //Create a build directory
cd build //Go the build directory
cmake -G "Unix Makefiles" -D CMAKE_OSX_ARCHITECTURES=i386 -D CMAKE_C_FLAGS=-m32 -D CMAKE_CXX_FLAGS=-m32 ..
