Make sure it is declared extern "C".

This is an error specific to your particular development system (MS VC),
and therefore off-topic in this newsgroup.

In a nutshell, you (or somebody else in case you're using a third-party
lib) compiled code with an option (/MD) to use the C Runtime code of a
shared DLL, but then you try to link with the static library version of
that Runtime code.

Consolidate your project settings (or, in case of a third-party lib, get
the version that was appropriately compiled).

If you have further questions, look for the appropriate newsgroup in the
microsoft.* hierarchy.
