Re: [Boost-users] Convert boost::shared_ptr to std::shared_ptr for boost::dll::import

What?! Good to know because it seems the friction between boost and its std counterparts (also with error_code, etc.) is steadily growing.

Knowing that, I'll have a much lower threshold for _not_ choosing boost when evaluating libraries.

The reason some libraries use boost::shared_ptr rather than std::shared_ptr has nothing to do with supporting VC7.1 at all. The most obvious reason is that a given library works with code at the c++03 level and does not require c++11 on up. You may feel that this is wrong, but this is another issue entirely than still having to support VC7.1. I offered a preprocessor based solution to supporting std::shared_ptr when it was available as opposed to boost::shared_ptr, along with the same sort of choice between other boost libraries and their c++ standard library counterparts, in my CXX Dual library at https://github.com/eldiener/cxx_dual. But it was not a popular solution for other Boost library developers and so almost nobody in Boost was interested in it. I still feel it is an eminently workable solution to the sort of problem which started this e-mail. But of course it is up to the individual library developer to decide what he wants to support.

Boost needs to support (a.o.) VC7.1 till eternity (needs to run on WinXP), so this will stay this way forever... "We don't support VC7.1" or "Move on", is NOT an option in 2018 as far as Boost is concerned.
