During migrating my project under new development environment I face out following issue: ambiguous unqualified 'shared_ptr' name resolution.

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:

What I have to do to avoid this errors for boost 1.36 except explicit share_ptr qualification?

Personally I'd get rid of all the using statements and then you'd never get this sort of error again. If you're too slow a typist to write boost::shared_ptr when you need it then typedef it to something shorter. Alternatively remove all #includes to boost\shared_ptr.hpp, or \include\memory. You don't need to include both the MS and boost shared_ptrs. Of course this won't work if some library header include the header you remove in which case see above. ****************************************************************************** "This message and any attachments are solely for the intended recipient and may contain confidential and privileged information.
