__NULL_IMPORT_DESCRIPTOR in boost_system and boost_filesystem

I'm linking the two Boost libraries to the project:

  • boost_system-vc120-mt-gd-1_55.lib
  • boost_filesystem-vc120-mt-gd-1_55.lib

Both libraries were recompiled locally with the default settings.

The VS2013 linker displays the following messages:

  • Debug build:
    • boost_filesystem-vc120-mt-gd-1_55.lib(boost_filesystem-vc120-mt-gd-1_55.dll) : warning LNK4006: __NULL_IMPORT_DESCRIPTOR already defined in boost_system-vc120-mt-gd-1_55.lib(boost_system-vc120-mt-gd-1_55.dll); second definition ignored
    • boost_filesystem-vc120-mt-gd-1_55.lib(boost_filesystem-vc120-mt-gd-1_55.dll) : warning LNK4221: This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library
  • Release build:
    • boost_filesystem-vc120-mt-1_55.lib(boost_filesystem-vc120-mt-1_55.dll) : warning LNK4006: __NULL_IMPORT_DESCRIPTOR already defined in boost_system-vc120-mt-1_55.lib(boost_system-vc120-mt-1_55.dll); second definition ignored

Should I just ignore these warnings or there is a way on how to fix them?

Getting boost built is a fair tragedy. Maybe you should use the prebuilt binaries. – Hans Passant

Well, it seems that the boost_filesystem just includes the boost_system so I've just removed the boost_system from the linker settings. Works well so far.
