Use VS to create a static link library Lib and use

One 、 Use VS Create a static link library .lib

1. Create a VS project

   * It could be a Empty item or VS The built-in Static library project Templates
   

   * Empty item There is no original code or file in , I prefer this mode

   * Static library The project has some original code and files , among pch.h Is a precompiled header file , Used to speed up compilation performance ;framework.h Files are automatically generated and can be ignored

2. Set the corresponding compilation options

   * Empty item ： Item attribute — Configuration properties — routine — Configuration type — choice Static library (.lib)

   * To configure and platform You can choose Debug、Win32 Or other settings , The caller can use the same configuration
   

   * Extra reminder ： Toolbar configuration and platform selection With the above Configuration and platform selection of the attribute interface It's a thing
   

3. Add code and generate

   * Add what you need The header file (.h) and Source file (.cpp)
   * Compile and generate

4. result

   Generated after , You can find the corresponding... According to the output prompt .lib file The location of
   

---

• Static library project ： The configuration type has been set to... By default Static library (.lib) 了 , Its original files can be left untouched , Add... In addition The header file (.h) and Source file (.cpp) that will do

Two 、 Use static link libraries in your projects .lib

Mode one ：

1. Copy the static library The header file (.h) and The library files (.lib) Go to project directory

   After copying to the project directory , take The header file .h Add to project ： The header file — add to — Existing items — Find the header file to add

2. Add... To the project properties The library files (.lib)

   Item attribute — Configuration properties — The linker — Input — Additional dependency — Write in the library file name

3. Include... In the code The header file (.h)

   // main.cpp In file 
   #include "LibTest.h" // Suppose my file name is LibTest.h
   

4. matters needing attention ：

   Platform used by the library (x64、x86) And configuration (release、debug) Should be consistent with the caller project

Mode two ： Don't depend on VS platform , Call... At the code level

• Relative path method is introduced

#pragma comment(lib, "LibTest.lib") //  When the library file is in the project directory , The relative path is used 
#include "LibTest.h"

• The absolute path method is introduced

#pragma comment(lib, "D:\\ desktop \\LibTest.lib") //  You can also use absolute paths 
#include "LibTest.h"

Mode three ： Direct will lib Add to the resource file of the project
