Hello, the code below doesn't compile (gcc-3.4.6 on Linux). 'transit in scope not defined' Any glue? Regards, Oliver
{ return transit< Z< S > >(); } <<=== error
Try { return this->template transit< Z< S > >(); }
Can anyone comment on whay this is necessary? Is it standard behavior or a gcc limitation?
It's standard behavior, dependent name lookup in templates. I faintly remember an article that explained the problem really nicely but can't find it right now. In a nutshell, when going through the template the compiler cannot know whether transit< Z< S > >() is a call to a member function of the base class or a call to a ctor of a class template. IIRC, this is because of possible template specializations of the base class.
gcc 4 has the same issue. If it is standard behavior, then the statechart docs need to be updated to reflect that because right now they don't include the "this->template " part.
You mean an example doesn't use that syntax? I'd be grateful for a pointer. Thanks & Regards, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
