gcc生成so檔案

準備三個檔案test.h, test.c, main.c

test.h

#include <stdio.h>

void say_hello();      

test.c

#include "test.h"

void say_hello(char *name){
    printf("hello %s\n", name);
}      

main.c

#include "test.h"

int main(){
    say_hello("guanxianseng");

    return 0;
}      

執行生成so檔案指令

gcc test.c -fPIC -shared -o libtest.so      

gcc main.c  -L. -ltest -o main
