I thought about that, but considering the fact that using windbg for a GCC compiled OS or GDB for a MSVC compiled OS makes little sense (although one could use that for mixed kernel+drivers setup), I decided to go the KDCOM way.

I am open to good arguments for doing that another way though.

Ah and I forgot : Jérôme, now you can use /DEBUGPORT=foo to load KDfoo.DLL ;) Then your KDfoo.DLL can implement a simple line parser in order to interpret any other hypothetical parameters present in the bootloader command line (some other KDxxx use that, for example KD1394 or KDUSB iirc.). One can imagine something like: /DEBUGPORT=GDB:COM1 to say: “Load KDGDB.DLL and use COM1 for it”. Currently it’s not what you did, maybe it would be great to have that? (and using /DEBUGPORT=COM1 just for loading KDCOM.DLL, the KD layer for WinDbg ?)

Sure, I will write one as soon as it is functional, but to make it short, it is as simple as launching gdb and using target remote <your_com_port>

On ReactOS side, /DEBUGPORT=COMx and you're ready to go.

Enjoy

Awesome, indeed! Any info or tuto about how to use it? About how to plug
GDB to it?
 
Cheers,

[KDGDB]
 - introduce KDGDB, a KDCOM-like DLL, wrapping the KD protocol and the GDB remote protocol together.
It is not fully functional, but for now it permits source-level debugging in some modules. More will be added as I feel the need and find the time to work a bit more on it. (That is, unless an angel comes and resume the work)
To use it, set GDB and _WINKD_ to TRUE in your CMakeCache.txt. Using separate debug symbols is also a good idea.
