GCC C语言 DLL范例，含源码

作者：小白救星
编译：gcc -c -DBUILDING_HZ_DLL1 hzdll1.c
           gcc -shared -o hzdll1.dll hzdll1.o -Wl,--kill-at,--out-implib,hzdll1.a
           或：gcc -shared -o hzdll1.dll hzdll1.o -Wl,--kill-at,--out-implib,hzdll1.lib
查看dll中的函数：dumpbin -exports hzdll1.dll

hzdll1.c

#include <stdio.h>
#include "hzdll1.h"

__stdcall void hello(const char *s)
//void hello(const char *s)
{
        printf("Hello %s
", s);
}

int Double(int x)
{
        return 2 * x;
}
