Using vector of references to a template class in the same template class.

[andreykuzmenko]

I am trying to create a template class, which would store a vector of
references to objects of the same class. Like:

template<class _core_t>
class Neuron
{
///snipped

private:
vector<Neuron<_ core_t>*> _neighbors;
}

But the compiler (MSVS8) says "missing storage class or type
specifiers" when it tries to compile vector definition line.

Where's the problem? Thanks!

Actually it's a vector of pointers.
Like:

template<class _core_t>
class Neuron
{
///snipped

private:
vector<Neuron<_ core_t>*> _neighbors;
} ;

Did you include <vector> ? Did you write "using std::vector"? Does this
code:

#include <vector>
template<class X> class A {
std::vector<A<X >*> v;
public:
A() {}
};
int main() {
A<int> ai;
}

compile for you? If not, the problem is in Redmond, Washington state,
U.S.A. But that's one you cannot fix. If it compiles (as it should),
the problem elsewhere in your code.

Sorry, it works... I just didn't mention "using namespace std;" at the
top to include vector definition.

Works fine with GCC. Probably a Microsoft problem. Or it could be your
missing semicolon at the end of the class definition. Or you could be
forgetting to #include <vector> or you could be forgetting to "using
namespace std;"
