Re: [tcf-dev] Overview needed

Hello Stefan,
I assume that what you're trying to do is compile a local (native) debug agent with TCF, and then start replacing services until that debugger talks to your remote server/controller instead of the local host. This sounds like a reasonable approach ("top-down approach").
Have you seen the "TCF Agent Porting Guide", it should help you get more understanding on this task:
http://git.eclipse.org/c/tcf/org.eclipse.tcf.git/plain/docs/TCF%20Agent%20Porting%20Guide.html
Note that for debugging the PE format on Windows, you need an updated DBGHELP.DLL installed as per the porting guide.
Also note that in case you want to debug your agent, you might want to build it with Visual Studio (unless you like gdb).
http://git.eclipse.org/c/tcf/org.eclipse.tcf.git/plain/docs/TCF%20Getting%20Started.html
I'll separately answer your other question regarding the daytime example.
I still think this "bottom-up approach" is also valuable for you.
So you approach your goals from 2 ends.
Thanks,
Martin

Hi Stefan,
you won't be able to debug this file using the current implementation of TCF because the file you generated using MinGW is in the PE file format but the debug information are in DWARF. As far as I know this is not supported by TCF right now, only by GDB.
Do you confirm Eugene?
I suggest you build a new .exe file using Visual Studio which will generate a PE file with MS debug format or that you switch to a Linux host (ELF + DWARF).
Cheers,
- Christophe

The server will offer functionality for a µController device such as runUntil(breakpoint) etc. and the agent will "only" have to receive this information, look up the correct line number which is mapped to the address where the device stopped and pass this information to eclipse such that this debug-stop can be visualized.

This and the actual part where the agent and my server exchange their data would have to be modified/written. The rest could stay as it is if I understood the agents purpose correctly.
