Unresolved external symbol referenced from module

The named symbol is referenced in the given module but is not defined anywhere in the set of object files and libraries included in the link. Check to make sure the symbol is spelled correctly.
You will usually see this error from the linker for C or C++ symbols if any of the following occur:

You did not properly match a symbol뭩 declarations of __pascal and __cdecl types in different source files.
    You have omitted the name of an .OBJ file your program needs.
    You did not link in the emulation library.

If you are linking C++ code with C modules, you might have forgotten to wrap C external declarations in extern 밅?

You could also have a case mismatch between two symbols.

Visual c에서 링크해서 컴파일하면 에러가 안나는데

위와 같은것은 어떻게 처리해야 하는지..
