Currently I am trying to port (steal ;) ) the Qt Creator debugger plugin, for use it with the MkS.
Today I've got a simple application, which contains unmodified code of the original debugger, and could load it and show it's UI and main menu. The current goal - a fully functional standalone (no Qt Creator, no MkS) debugger based on the debugger plugin codebase.
I think, 35% of work is done.
Sources are there:
