Hello,
I'm using Eclipse CDT on Windows 7, with MinGW as my toolchain and GDB as my debugger. For the most part I have been able to get everything working normally, including the development of Java, C/C++, and JNI applications.
However, I am unable to debug the native side of those JNI applications. The Java debugger works fine for Java code and GDB works fine for purely native code, but I cannot seem to get GDB to operate properly on code within a JNI .DLL.
I have searched the web for quite a while regarding this, and it sounds like the success people have had is by attaching to the running Java process after launching it from Eclipse. Then, setting a breakpoint and letting GDB hit it. Unfortunately, this does NOT seem to work for Windows users.
The only advice that seems to work ( which I can confirm ) is to launch the Java application in Eclipse, then attach to the process from Visual Studio. From there you can set breakpoints in the native code, and they will be hit. This approach is a pain in itself, but what really makes it awful is that you need to have compiled the .DLL from Visual Studio in order to generate the .PDB file for debugging symbols. Making the whole CDT somewhat extraneous at that point.
I'd much prefer to stay within Eclipse, but only if I can actually debug with it. Can anybody out there confirm if it's possible to debug JNI code with Eclipse CDT from Windows?
