After a long time I am happy to introduce Beaver Debugger. It is GDB frontend, integrated with MkS.
MkS was not having debugger for a long time. There was few attempts to create it.
Main difference of Beaver Debugger integration with debuggers of other IDEs including Qt Creator is that we are not going to create one big application. We prefer to have 2 simple. The debugger is separate application. When user wants to debug his application, he can quickly start Beaver Debugger session from MkS. This allows to simplify IDE interface.
Currently debugger is far from ideal, but, MkS also has a lot of opened bugs. So, debugger will be improved after bug fixing.
