cygwin c创建动态/静态链接库 - c++编程基础

test.c

int num()  
{  
    static int i = 0;  
    return i++;  
}

main.c

#include "stdio.h"  
  
extern int num();  
  
int main()  
{  
    printf("%d\n", num());  
    printf("%d\n", num());  
    printf("%d\n", num());  
    return 0;  
}

1.动态链接库

a.gcc -shared -fPIC -o libtest.dll test.c[生成libtest.dll]

b.gcc -o main main.c -L. -ltest[生成main.exe]

c../main.exe

2.静态链接库

a.gcc -c test.c[生成test.o]

b.ar crv libtest.a test.o[生成libtest.a]

c.gcc -o main main.c -L. -ltest[生成main.exe]

d../main.exe
