I'm getting a link error when following the counter tutorial from the following page:

I think it's because you need to define MSW in the preprocessor defines section so that "EXPORT" in m_pd.h is replaced by "__declspec(dllimport)". Otherwise it's just "extern" and the linker can't find it.
Another way to avoid that error is to replace any ocurrence of &s_float with gensym("float") but then you'll probably run into more trouble down the line.

Thanks. The MSW fix worked. Funny that m_pd.h can't figure that out automatically....
