Hi Brn,
This is a closer but it is still not enough to be able to help you. We
need a code /snippet/ - cut down the code to the minimal necessary so
that we can compile the code and see the problem. Your code below won't
compile because it is missing some defines, and it has lots more code
making it hard to see where the problem might lie. It could well be
that your code here (once you've included the missing defines) /is/ the
minimal code that shows the error, in which case adding the missing
parts should be easy enough.
You are also missing the compile flags and the compiler version.
Without these, we can't replicate the error or give useful advice (such
as alternative compiler flags to try).
mvh.,
David
