 It would have helped a lot to know what did the warning actually say, but
combining this piece of information ...

... with that one I'd say that you're using wxWidgets 2.8 in Unicode build
on your PC but ANSI build on your laptop.

 The wx/setup.h files used are different though.

 The only explanation for this is that you also built wxWidgets as static
library on the PC because otherwise it simply can't work without all the
shared libraries it depends on.

 Either reconfigure and rebuild with --enable-unicode or just use wxWidgets
3.0 (which is currently at RC2 step but will be released in less than a
week) where there is no difference between ANSI and Unicode build any more.
