[Boost-users] program_options inconsistent dll linkage

Hi

We were having problems while linking boost program_options dynamically in
Visual Studio.NET 

Linking to lib file: boost_program_options-vc71-mt-gd-1_33.lib
d:\Develop\SDK and
Libraries\boost_1_33_0\boost\program_options\variables_map.hpp(130) : warning
C4273: 'boost::program_options::store' : inconsistent dll linkage
d:\Develop\SDK and
Libraries\boost_1_33_0\boost\program_options\variables_map.hpp(138) : warning
C4273: 'boost::program_options::store' : inconsistent dll linkage

Problem is that in file variables_map.hpp 'BOOST_PROGRAM_OPTIONS_DECL ' is
missing in friend declaration of function 'store'.

so:

=======================

    class BOOST_PROGRAM_OPTIONS_DECL variables_map : 
                              public abstract_variables_map,
                              public std::map<std::string, variable_value>
    {
     ...
        friend void store(...);
    };
    ...
    BOOST_PROGRAM_OPTIONS_DECL void store(...);
     
=======================

should be:

=======================

    class BOOST_PROGRAM_OPTIONS_DECL variables_map : 
                              public abstract_variables_map,
                              public std::map<std::string, variable_value>
    {
     ...
        friend void BOOST_PROGRAM_OPTIONS_DECL store(...);
    };
    ...
    BOOST_PROGRAM_OPTIONS_DECL void store(...);
     
=======================
