@section java_comp_max Building JPortAudio on Mac
These are notes from building JPortAudio on a Mac with 10.6.8 and XCode 4.
I created a target of type 'C' library.
I added the regular PortAudio frameworks plus the JavaVM framework.
I modified com_portaudio_PortAudio.h and com_portaudio_BlockingStream.h so that jni.h could found.
@code
#if defined(__APPLE__)
#include <JavaVM/jni.h>
#else
#include <jni.h>
#endif
@endcode
This is bad because those header files are autogenerated and will be overwritten.
We need a better solution for this.
I had trouble finding the "libjportaudio.jnilib". So I added a Build Phase that copied the library to "/Users/phil/Library/Java/Extensions".
On the Mac we can create a universal library for both 32 and 64-bit JVMs. So in the JAR file I will open "jportaudio" on Apple. ON WIndows I will continue to open "jportaudio_x64" and "jportaudio_x86".
