While building liblouisutdml 1.9.0 on OS X 10.6.7, I found a few extra steps needed that could be useful to add to the README.mac. 1. Download and install the Java Developer Package from http://connect.apple.com. This provides the jni.h include file needed by the Java binding class. 2. Update the include path to be able to find jni.h. I don't know if there is a more elegant way of doing this, but I needed to change a line in tools/Makefile and liblouisutdml/Makefile: * BASE_DEPENDENCIES_CFLAGS = -I/usr/local/include/liblouis -I/usr/include/libxml2 -I/System/Library/Frameworks/JavaVM.framework/Headers Thanks, John Brugge
