I've reached the point in the development of the Windows build files for liblouisutdml where it is compiling individual modules. For the C part of the Java bindings it has the path to where jni.h is located in my installation of openjdk-1.6. It finds jni.h, but jniljh wants jni-md.h (machine-dependent). It seems that openjdk-1.6 doesn't have it, because I've encountered this problem before. Has anyone else? What is the solution? Thanks, John -- John J.
