提问by annunarcist
I am using eclipse CDT to test the Intel instructions and below is my program:
我正在使用 eclipse CDT 来测试英特尔指令，下面是我的程序：
#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);
}
When I compile the above code, I get linkage error as:
当我编译上面的代码时，我得到链接错误：
Info: Internal Builder is used for build
gcc -O0 -g3 -Wall -c -fmessage-length=0 -o "src\Intel.o" "..\src\Intel.c"

Please help me regarding the issue.
请帮助我解决这个问题。

Your program isn't complete. You need to implement the OS-expected entry point. In your case, that looks like it's called WinMain.
你的程序不完整。您需要实现操作系统预期的入口点。在您的情况下，它看起来像是称为WinMain.
回答by Chandra Shekhar
Yes, Main () function is missing and the compiler is not able to find an entry point for executing the program.
是的，缺少 Main() 函数，编译器无法找到执行程序的入口点。
One more reason is even if you have written the main function but if you didnot save the .cpp file and try to compile it will give the same error.So make sure you have successfully saved the .cpp file and then compile and run your code.
另一个原因是，即使您已经编写了 main 函数，但是如果您没有保存 .cpp 文件并尝试编译它也会出现相同的错误。因此请确保您已成功保存 .cpp 文件，然后编译并运行您的代码.
