Create and use static libraries and dynamic libraries in Windows

I. Creation and use of static libraries

1. Creation of a static library

(1) In VS2013, select the menu->file->new->project, select the Visual C + +->win32 option, then click the Win32 Project icon and select Win32 Application Wizard, select the static library option under Application type. The project name is Teststaticlib.

(2) Create a new Test_header.h header file under the header files of the Solution Explorer

1 #ifndef Test_header_h_2 #defineTest_header_h_3 4 #ifdef _WIN325 #ifdef _lib6 #defineDECLSPEC __declspec (dllexport)7 #else8 #defineDECLSPEC __declspec (dllimport)9 #endifTen #else One #defineDECLSPEC A #endif -  - #endif

The __declspec modifier is only valid under the Windows platform.
The role of __declspec (dllexport) is to export the current function or class so that it can be called from the DLL.

The role of __declspec (dllimport) is to use exported DLL functions or classes in your application.

When you create a new static library project in the VS2013 compiler, the _LIB macro is predefined, so the above code

#define DECLSPEC __declspec (dllexport) is effective.

(3) Create a new Source.h file under the header files of the Solution Explorer

1 #ifndef Source_h_2 #defineSource_h_3#include"Test_header.h"4 5DECLSPECintMyFunction (intAintb);6 7 classDECLSPEC MyClass8 {9  Public:TenMyClass (intAintb): M_a (a), M_b (b) {} One~MyClass (); A     intAdd (); - Private: -     intm_a; the     intM_b; - }; - #endif

(4) Create a new Source.cpp file under the Source Files folder of the Solution Explorer

1#include"Source.h"2 3 intMyFunction (intAintb)4 {5     returnA +b;6 }7 8myclass::~MyClass ()9 {Ten } One  A intMyclass::add () - { -     returnM_a +M_b; the}

(5) Compile the project, the TetsStaticLib.lib static library file will be generated under the Debug folder of the project catalog.
2. Use of static libraries

(1) Create a new WIN32 console project, named Testlib.

Set project properties for Testlib

①configuration properties->c/c++->general->additional Include Directories

D:\program\c++pro\teststaticlib\teststaticlib

②configuration properties->linker->general->additional Library Directories

D:\program\c++pro\teststaticlib\debug

③configuration properties->linker->input->additional Dependencies

TestStaticLib.lib

(2) Add the following test code

1#include"stdafx.h"2#include"Source.h"3#include <iostream>4 using namespacestd;5 6 7 int_tmain (intARGC, _tchar*argv[])8 {9     intc = MyFunction (1,2);Tencout << C <<Endl; One  AMyClass CLA (2,4); -cout << Cla.add () <<Endl; -System"Pause"); the     return 0; -}

(3) Compile and run the generated TestLib.exe, you can see the results of the program, then copy the TestLib.exe to any folder can also run.
