GCC issue with template

I want to use the below garbage collector, but when I would compile I get a lot of error with GCC but not with VSC++, i.e this.

list<GCInfo<T> >::iterator开发者_高级运维 p; ---> Expected ';' after expression

And here is the library.

Assuming T is a template parameter, you need a typename:

typename list<GCInfo<T> >::iterator p;
^^^^^^^^

For more about when and why typename is required, see the Stack Overflow C++ FAQ "Where and why do I have to put template and typename on dependent names?"
