I have tried OBF's new debugger plugin which use GDB-MI interface.
GIT source address
https://github.com/obfuscated/cb_gdbmi
EDIT 2013-05-09 : the current status of this plugin is HereI build it under MinGW 4.6.x, and here is what I changed:
It looks like int32_t and int64_t is not defined.
So, I add such code snippet:(in src\cmd_queue.h)
typedef int int32_t;
typedef long int int64_t;
I adjust some include search path, I think the whole src folder can be put under:
cb_trunk\src\plugins
So that only relative include search path is needed. (Just like other plugin sources), also using this way, the pack.bat maybe are not needed.
Anyway, this plugin works GREAT!!!
