[boost] Re: [Config] proposal of new macro, BOOST_DECL

In order to export class from dynamic library one needs to add something as:

__declspec(dllexport)

wrapped in a macro. (Win32 example.)

Right now libraries define their own macros, e.g Iostreams has BOOST_IO_DECL and Regex uses BOOST_REGEX_DECL. There could be more.

I suggest common macro, BOOST_DECL to be used Boost-wide.

Its value may be by default empty or deduced from BOOST_ALL_DYN_LINK as it is done in Regex.

It may be important to link a static version of one library with a dynamic version of another. That wouldn't be possible with a single macro. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
