静态链接

1.建立静态链接库

File→New→Project→Static library

示例：
建立静态链接库工程：StaticLibrary，

static.h

#ifndef STATIC_H_INCLUDED
#define STATIC_H_INCLUDED

#ifdef __cplusplus
extern "C"
{
#endif

int SampleAddInt(int i1, int i2);
void SampleFunction1();
int SampleFunction2();

#ifdef __cplusplus
}
#endif

#endif // STATIC_H_INCLUDED

static.c

// The functions contained in this file are pretty dummy
// and are included only as a placeholder. Nevertheless,
// they *will* get included in the static library if you
// don't remove them :)
// 
// Obviously, you 'll have to write yourself the super-duper
// functions to include in the resulting library...
// Also, it's not necessary to write every function in this file.
// Feel free to add more files in this project. They will be
// included in the resulting library.
#include "static.h"  
// A function adding two integers and returning the result
int SampleAddInt(int i1, int i2)
{
    return i1 + i2;
}

// A function doing nothing ;)
void SampleFunction1()
{
    // insert code here
}

// A function always returning zero
int SampleFunction2()
{
    // insert code here
    
    return 0;
}

工程文件包括static.h和static.c，具体如下，然后编译工程，会生成一个libStaticLibrary.a文件。
libStaticLibrary.a是用于链接的，与其他文件一起编译生成一个exe执行文件。

2.建立主工程

建立Console application




将生成一个main.c示例文件，在最上方添加#include "static.h"语句，这样就可以调用静态链接库里的函数了。

#include 
#include 

#include "static.h"

int main()
{
    int a = 1, b = 2;
    printf("a + b = %d\n", SampleAddInt(a, b));
    printf("Hello world!\n");
    return 0;
}

然后选择菜单栏Project->Build Options，弹出Project Build Options，选择工程名称。在Linker settings选项卡下添加libStaticLibrary.a的路径，即添加需要的库。



在Search directories选项卡下的Compiler子选项卡下添加static.h所在的目录路径，即写入项目的头文件目录。

最后，点击编译即可。
