Cannot make a vector of structs in C++

I'm trying to do the following:

struct Code
{
    GF2X generator;
    vector<GF2X> codeWords;
};

vector<Code> allCodes;

However, I end up with this error:

error: template argument for 'template<class _Alloc> class std::allocator' uses local type 'main()::Code'|

I'm completely lost as to what this means. This is also my first time programming in C++.

In C++03 local classes (classes defined inside a function) cannot be used as template arguments. That restriction was lifted in C++11, but if your compiler does not have support for this feature you can always move the type definition outside of the function at namespace level.

You haven't posted all your code, but I'm guessing that you put struct Code ... inside your main function. Try moving it above the start of main.

Define the struct outside (but before) your int main().
