__WXMSW__ ... Don't you've to build them for Unix/Linux? As you can run your applications in X

I think you don't need the Windows Version of wxWidgets, but the wxX11-version (you can grab it from their site) ...

Tried that and configured without msw and got this when I did make

Check out this

I tried that when I first started, I just tried it again, and both times(at least I think this happened last time) I got this result

make: *** [baselib_appbase.o] Error 1

Before I let this thread die I'll ask one more question.

Until now I'd forgotten the error I got when I followed the instructions at wxwiki for cygwin since I had tried so many different methods since then. So, does anyone know why I would get this error(first error in the make output)?

./include/wx/wxcrtbase.h:641: error: `_wcsdup' undeclared (first use this functi
on)

Did you actually read this carefully?
The instructions are very clear
