So lets see if I got it right.

I declare the vector at the header without his size (3 in this case).

And at the constructor or create method I initilize the vector and then I set his size?

how do I set the size of the vector?

 

Thanks, again.

the header compiles fine with

gcc version 3.3.5 (Debian 1:3.3.5-13)

Did you mix declaration and instantiation? If you want that cov has size
3 by default you can either use the constructor or the create function
(but this is part of the implementation file):

simple_env() : cov(3) { ... more ... }
create()
{
cov.resize(3, false);
}
