Re: [cdt-debug-dev] How to develop a non-gdb debugger for CDT?

[Haim Cohen <haim.cohen@xxxxxxxxxx>]

It seems you have 2 options :

A : Implement gdb MI interface in your debugger. You should check what 
are the gdb commands sent to gdb by CDT, and what is the output of each 
command. You can learn about it by running gdb from command line.
The interface to gdb is located in the commands and, run them in gdb and 
look at the output to see if you can supply this information from your 
debugger.

B : Using the existing interface of your debugger, create new commands 
and output classes, to interact with your debugger. There is some 
parsing work here, so plan your debugger interface carefully.

Of course, instead of running the local gdb, run your debugger.

I am curious - what is the DSP you develop the debugger for ?
