Ok, I could build the sample and it is working.
But the problem using this build with fwh remains. I get these unresolved
externals
Error: Unresolved external '__rwstd::__rw_stdexcept_NoNamedException'
referenced from D:\XHARBOUR_9\LIB\HBZIP.LIB|ziparchive
Error: Unresolved external 'std::basic_string<char, std::char_traits<char>,
std::allocator<char> >::__nullref' referenced from

thanks for help
