  1. Hi all, I'm trying to create a DLL for a simple SystemC model using Microsoft Visual C++ 2019. After building SystemC DLL (DebugDLL) and following MS doc to create a DLL, I'm having linking errors like: 1> Creating library <path>\SimpleLib\Debug\SimpleLib.lib and object <path>\simple\SimpleLib\Debug\SimpleLib.exp 1>SimpleLib.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall sc_core::sc_module_name::~sc_module_name(void)" (__imp_??1sc_module_name@sc_core@@QAE@XZ) referenced in function "public: __thiscall myclass::myclass(class sc_core::sc_module_name)" (??0myclass@@QAE@Vsc_module_name@sc_core@@@Z) 1>SimpleLib.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __thiscall sc_core::sc_simcontext::sc_simcontext(void)" (__imp_??0sc_simcontext@sc_core@@QAE@XZ) referenced in function "class sc_core::sc_simcontext * __cdecl sc_core::sc_get_curr_simcontext(void)" (?sc_get_curr_simcontext@sc_core@@YAPAVsc_simcontext@1@XZ) (attached complete log) What could be the problem? The code is the one from the post link: // SimpleLib.h #pragma once #ifdef SIMPLELIB_EXPORTS #define SIMPLELIB_API __declspec(dllexport) #else #define SIMPLELIB_API __declspec(dllimport) #endif #include <systemc.h> class SIMPLELIB_API myclass : public sc_core::sc_module { public: myclass(sc_core::sc_module_name name); void display(); }; //SimpleLib.cpp #include "pch.h" // use stdafx.h in Visual Studio 2017 and earlier #include "SimpleLib.h" myclass::myclass(sc_core::sc_module_name name) : sc_core::sc_module(name) { std::cout << "Inside cons\n"; } void myclass::display() { std::cout << "Calling display\n"; } Configuration of the SimpleLib project was done also following INSTALL (Building against a SystemC DLL): C/C++ -> General -> Additional Include Directories is set to: <my_path>\systemc-2.3.3\src Added SC_WIN_DLL to: C/C++ -> Preprocessor -> Preprocessor Definitions Linker -> General -> Additional Library Directories is set to: <my_path>\systemc-2.3.3\msvc10\SystemC\DebugDLL log.txt
