Hi Clebert. I've actually made some progress here. There are a couple of issues I found: 1. The JVMPI binary shipped for Mac OS X is specific to PowerPC. However, it is easy to re-compile it and get an Intel binary. I am going to research how we can change the script to produce a Universal Binary, and then you can include that in the download instead. 2. There is no JVMTI binary included (which is where we started :-)). The compile.sh script wasn't working, and after a while I figured out that this is because it is using DOS carriage returns. Converting it to unix format makes the script run correctly, and I now have a .jnilib file :-). I'll test it out and see if it works. -- Matt View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966120#...
