Hi Paolo,
I get a similar problem, but not when compiling the wxWidgets library
itself, only when linking to it in my projects. Given that the problem
is with calls to wxAssert, etc, which is only compiled in debug
configuration, you'll probably find that you can build the release
version sucessfully. Chances are you won't ever need to actually debug
inside the wxWidgets library, so this may well be an acceptable
workaround.

To solve my problem, I can use the workaround suggested at

so you might want to see if this helps you.

Cheers,
Tom
