+@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".
