Does it work with an older nightly or 13.12, or even 12.11?
(most of the time I ignore long posts)

Actually SDCC uses .rel extension instead of .o extension for object files. You have to configure CB to use .rel extension in the advanced settings somewhere.

I think splitting the compiler into .o and .rel object file types would be a reasonable quick fix.

No idea if the PIC is the only one needing .o object files; if yes, then calling it SDCC PIC as was suggested in the other thread sounds good to me.

Might be worth it to even split SDCC more if there is a large difference in compiler options for the back ends.

Where can i set the output file extension? I can not find the option?

I find it.

need reopen the project.

thanks.
