I still have problems to install Language::Prolog::Yaswi under cygwin (see Problems installing Language::Prolog::Yaswi). But I'm a bit further:

• compiled SWI Prolog 5.6.3 under cygwin -- ok
• perl -MCPAN -e 'install Language::Prolog::Yaswi' started
• opaque.c compiles...

But now I get the following error:
