I begin my summer of code by getting in touch with Eclipse community and other gsoc students working on Eclipse projet. During these first weeks I read documentation on the Eclipse framework and some tutorials. I sent an email to CDT-dev mailing list to announce the project and to get feedback and some pointers. Thanks to a response I found an interesting presentation from Intel's guys, who propose a new debug interface for mixed applications, XDI (eXtensible Debug Interface), in remplacement of the current JDI (Java Debug Interface). In the document they present several approaches to provide mixed mode debugging in Eclipse with advantages and problems for each approach. However XDI is not yet standardized and requires an XDI agent implementation in the JRE.
My mentor gave me too some links on existing work. One presentation explains how to debug JNI application currently with Eclipse. It's not so easy but it's possible. As I see currently see it, my job will consist in automating that so that becomes seamless and more powerfull.
I hope to succeed, it will be really nice to have this feature in Eclipse.
