Linker can't find LIB file of the DLL imported

I've looked through full 14 pages list of similar problems but didn't find my case.

I have VS2017 c++ solution which has two projects DLL and EXE. EXE projects includes DLL header to import function from it.

The problem is that linker can't find dllproject.lib file. I tried to add it to Linker -> Input -> Additional Dependencies but didn't help because linker failed to find that lib file and it exists in the output folder.

Then I used

#pragma comment( lib, "C:\\FULL_PATH\\dllproject.lib")

And this time helped. But the problem is my local absolute path to the lib. I suppose I can somehow configure that in the project settings, but all my attempts failed.

In the DLL header file I have the block (was advised in other answers).

#ifdef MYDLL_EXPORTS
#define MYDLL_API __declspec(dllexport)
#else
#define MYDLL_API __declspec(dllimport)
#endif

Please help.

Solution

  • Adding a library to your project is a two step process.

    You add the library name to Linker/Input/Additional Dependencies and you add the library folder to Linker/General/Additional Library Directories.

    Then of course you have the potential problem of your program failing to find your DLL, but that's another question.
