I just want to tell you that some kind soul sent me the following
advices, which solved the problems for me:
this should fix your problems:
1. Add ws2_32.lib and mswsock.lib to your depend libraries (fixes unresolved
symbols)
2. Check the runtime library for APR/ApU and your project, they should be the
same (e. g. multithread or multithread dll) (fixes multible symbols)
Now, what I still do not know, is: Should I have known this? Is there
some documentation missing or is it my missing experience with
development under Windows?
Thank you all,
Joachim
