By mistake I started a new trhread, thx for the help. How can i do case-insensitive linking at uvision2?
I don't know off hand - you will have to look in the Linker Manual
How can i do case-insensitive linking at uvision2? Wrong question. You had better fix your source code to be internally consistent. The C programming language is defined to be case-sensitive, so you really shouldn't rely on being able to turn any given compiler in to case-ignoring mode.
"Wrong question. You had better fix your source code to be internally consistent" Absolutely! At the moment you are relying far too much on luck: 1. Your are using illegal identifiers in your include-guards - it is only a matter of luck that they haven't clashed with some internal, undocumented compiler identifiers; 2. You have used the wrong identifiers for your functions calls - it only works by luck because you seem to have case-insensitive linking (and that by accident rather than design). Your lucky spell can only last so long - even a cat only has nine lives... ;-)
