[ros-dev] About debugging ROS

[Timo Kreuzer]

Hi,

In theory you can also use winDbg for debugging. You need to compile 
reactos with KDBG = 0 and _WINKD_ = 1
Then you need a connection between WinDbg and kdcom. You can use com0com 
and map the VM serial port to one
end of the pair and connect winDbg to the other. This works quite well 
with qemu and VBox.
after WinDbg is connected you should be able to do the basic stuff, like 
stepping, viewing and changing registers, dumping memory. What not works 
is attaching to processes, as WinDbg needs symbols for that. so you 
would need to compile with MSVC, which is work in progress. This 
currently limits its usability quite a lot.

I used it only on x64, so I can't say how good it works on x86. But 
afaik it works quite well, except that connecting can be a little tricky 
in the beginning.
