Question

I am using two large libraries (GUI & network) and I can happily do

using namespace FirstLib;
using namespace SecondLib;

Except for 1 single class called Foobar where names clash.

I my code, I do not use FirstLib::Foobar. Is there a way to say “in my code, whenever you see Foobar, think SecondLib::Foobar ?

Answer 1

It’s strange nobody suggested to replace the full namespace use by the list of used class names. This solution is even in the C++faq (where I should have thought to look first).

If we cannot say

include all FirstLib, but remove SecondLib::Foobar

We can use using-declarations of the exact elements we need:

using FirstLib::Boids;
using FirstLib::Life;
// no using FirstLib::Foobar...
