C++ DLL import class unresolved external symbol

QUESTION

C++ DLL import class unresolved external symbol

Asked 2021-Mar-01 at 19:01

Hi I'm sorry I've seen that there is a lot of "unresolved external symbol error" questions, and I've seen them but none of the answers that I found fixed my error.

I've tested 2 ways to compile the DLL and use the HelloWorld method from SerialPort class. btw I'm using VS2019 community edition

Both ways are throwing the same error :

You are calling HelloWorld which is missing its implementation in your application.

There is some fundamental misunderstanding about how C++ executables are compiled and linked against DLLs.

No libraries:

All symbols that the Application needs must be defined in the Application.
All needed symbol definitions must be available to the linker.

Static libraries:

All symbols that the Application needs must be defined in the Application or a static library.
All needed symbol definitions must be available to the linker.
The symbols are added to the generated Application's executable.

Dynamic libraries:

All symbols that the Application needs must be defined in the Application or a dynamiclibrary.
All needed symbol definitions must be available to the linker.
The symbols remain at their original places and they are loaded only at load time. This allows swap the dynamic libraries with any other ABI-compatible one at load time.

Since you are not linking with the dll and only load it at runtime, the linker correctly complains about the missing HelloWorld method.

Extern "C" is irrelevant here.
