未定义对“ WinMain @ 16” collect2.exe的引用：错误：ld返回1退出状态 [英] undefined reference to `WinMain@16' collect2.exe: error: ld returned 1 exit status

问题描述

我正在使用Eclipse CDT来测试Intel指令，以下是我的程序：

I am using eclipse CDT to test the Intel instructions and below is my program:

#define cpuid(func,ax,bx,cx,dx)\
__asm__ __volatile__ ("cpuid":\
 "=a" (ax), "=b" (bx), "=c" (cx), "=d" (dx) : "a" (func));
int Check_CPU_support_AES()
 {
 unsigned int a,b,c,d;
 cpuid(1, a,b,c,d);
 return (c & 0x2000000);
 }

编译以上代码时，出现链接错误：

When I compile the above code, I get linkage error as:

Info: Internal Builder is used for build
gcc -O0 -g3 -Wall -c -fmessage-length=0 -o "src\\Intel.o" "..\\src\\Intel.c" 
gcc -o Intel.exe "src\\Intel.o" 
c:/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../libmingw32.a(main.o):main.c:(.text.startup+0xa7): undefined reference to `WinMain@16'
collect2.exe: error: ld returned 1 exit status

请帮助我解决该问题。

推荐答案

您的程序尚未完成。您需要实现操作系统期望的入口点。在您的情况下，它看起来像是 WinMain 。

Your program isn't complete. You need to implement the OS-expected entry point. In your case, that looks like it's called WinMain.
