Thank you very much for your replies.
If I understood you well, my original task (use IAR generated library in
SDCC) is also not feasible?
Do you know of any other C compiler that I might use as a replacement for
SDCC. I also need my project to be as safe and reliable as possible. Maybe
choosing an open source compiler is not a good decision? I would need
something that's cheaper than IAR...?
Thanks in advance
