I think this is how it works. Using C++ API, you can create multiple instance of the debugger and then multiple instances of target in any debugger instance.

As pointed out in https://bugs.eclipse.org/bugs/show_bug.cgi?id=405670, Apple has dropped gdb from the latest Mavericks OS release. I also noticed that gcc in the latest
Xcode command-line tools actually runs clang (although I imagine the gcc driver respects gcc arguments).
At any rate, in order to properly support Mac as a target for CDT in the future, we’ll need proper support for these tools. And to be honest, that’s a good thing since these tools are pretty good and cross platform to Linux at least, and
something we should get to know anyway.
Any thoughts on how we’d kickstart this activity?
lldb has a native C++ API as well as a python based one which could be used to script interaction instead.
Depending on which level is chosen it might make sense to have a generic lldb wrapper and then have the debug CDT code work against that intermediary layer.
One disadvantage of having the native code is that it might be difficult to spawn multiple executions of lldb or require a restart of Eclipse between runs.
Hi Alex, could you expand on that? I thought the way it worked is that you loaded the lldb dylib and using its APIs you could create and run any number of targets, even remotely. I was thinking it would be nice (maybe too optimistic) to do it similarly to SWT
and have a thin JNI layer (Swig?) that would map everything to Java and hopefully this would be faster too. To me, the disadvantage of this approach is possibly crashing the whole Eclipse process because of a crash in LLDB.
On the other hand since Python is supported in lldb you could have a python remote debugger serving on a TCP port and then drive everything through the network. That might make remote debugging easier too.
Do you know if Xcode does use the Python bindings? I thought maybe it would be slower, especially when doing "lower level" operations like retrieving memory. But if Xcode does it that way with satisfactory results, perhaps this would be the safest approach.
Thanks,
