In general, it's much more useful to get the complete build log, not
just the error message. The error message doesn't tell us anything about
the libraries linked (or not linked), and the options used to compile.
Look into the Output window, at the bottom there is a line saying 'Build
log was saved at "file://c:\..."' (or the equivalent in italian. ;), and
attach that to the message, please.

I can only guess, but my guess would be you're not linking with the
STLPort library, therefore it can't find some of the symbols that are
used when OSGLog.h includes fstream. Or you are linking with the
library, but you're still using the old headers.
