I've read everything on foosion's web page. SDK is made for Visual Studio 2005, but this is really looks like a nonsense - i can't compile foosion's sample plugin 1 it using Visual Studio 6/2003. The error I see can't DEPEND ON difference in 2003 and 2005 studios (i believe):

d:\tools\foobar2000\sdk\pfc\int_types.h(67) : error C2146: syntax error : missing ';' before identifier 't_size'

Can anybody help me?

The SDK does not compile on VS 2003. This is a fact. If you modify it in order to do so, your component will probably end up doing Bad Things and crashing.

Thanks, I've already understood that 2005 studio is a must here
