Building wxWidgets 2.8.6 linker error with VS2005

[konokono]

Hi all,
I'm trying to build wxWidgets 2.8.6 with VS2005, but I get the following 
errors compiling the 'core' project:

1>Linking...

I've tried to include appbase.cpp (where 
wxAppTraitsBase::GetAssertStackTrace is defined), but I get other 
errors. Does anyone know where is the problem?

Thanks in advance,
Paolo
