How to compile Ressource File

[c.panel]

I have problems with codeblocks logic...
How can I compile a RC ressource file : I try to right click but no compile option ? (with CPP it does)
I'm trying to use GNU toolchain.
I have painly found the command line that should compile with windres and it seems to make a COFF file : "-O coff" (unknown extension for me : binary format for GNU linker ?)
But When I make the project I have strange errors

...fatal error: when writing output to : No such file or directory

then

windres.exe: preprocessing failed.

My questions :
-Where can I find detailed informations about windres (not only online help)
-Does WindRes accept any RC files (precompiled directives, ...) ?



thanks a lot for your answers (and for this very interesting freeware)
