Hello, I have some C99 code used by C++11 application code. A few inline functions are declared in the C99 style with code explicitly generated in the translation unit using the C99 extern inline. However, when I try to use one of the inline functions in the C++ application, I get errors about multiple definitions at link time. It seems that g++ is instantiating the inline code that already exists in the library, despite the extern "C" specifier.
Your issue seems specific to windows. On linux, gcc does instantiate the inline code, but it emits a weak symbol in app.o that is discarded at link time in favor of the strong one in buffer.o.
