Re: [Boost-users] shared_ptr and Visual Studio 2008 Express SP1

Hi, "using" the whole namespace is not healthy, because you "dirty" the global namespace and raise the probability of conflicts. Instead, you could "import" some specific classes: using boost::shared_ptr; Then, if you decide to use the tr1 one, you just change it to: using std::tr1::shared_ptr;

For example in .cpp files I using several usings such as:

using namespace std; using namespace std::tr1; using namespace boost;

In source code I have something like this:

shared_ptr<SomeType> var = /*...*/;

And for each such line I have an error: error C2872: 'shared_ptr' : ambiguous symbol
