C++ - 对`WinMain@16 的未定义引用 [英] C++ - undefined reference to `WinMain@16

问题描述

我在网站上得到了 .h 和 .cpp 代码，我正在尝试编译它们.这是包含代码的网站:http://raphaelcruzeiro.com/blog/implementing-a-sha1-algorithm-in-c/

I got a .h and .cpp codes on a website and I am trying to compile them. This is the website that contains the codes: http://raphaelcruzeiro.com/blog/implementing-a-sha1-algorithm-in-c/

我正在创建一个新项目，选择控制台应用程序"并将 .h 和 .cpp 文件添加到项目中，但是当我尝试编译时，我总是收到此错误未定义对 WinMain@16 的引用".

I am creating a new project, selecting "console application" and adding the .h and the .cpp files to the project, but when I try to compile I always get this error "undefined reference to `WinMain@16".

我尝试过 DevC++ 和 Codeblocks，他们都遇到了同样的错误.

I tried DevC++ and Codeblocks both of them got the same error.

请问我想要有关如何编译这些文件的所有详细信息，是否可以使用#include?如果你们请一步一步做一个简单的我会很高兴.

Please I want all details on how to compile these files, is there a #include to use? If you guys please make a simple step by step I would be very glad.

在本网站 http://raphaelcruzeiro.com/blog/implementation-a-sha1-algorithm-in-c/ 你会找到 .h 和 .cpp 代码.

推荐答案

所有 C++ 程序都需要某种 main() 函数，这是它们开始执行的地方.网站上的代码没有 main()，导致编译器抱怨(这是正确的 - 程序不知道从哪里开始).

All C++ programs require some sort of main() function, which is where they start executing. The code on the website has no main(), causing the compiler to complain (and rightly so - the program wouldn't know where to start).

您需要在 .cpp 文件中添加如下内容:

You'll need to add something like the following to your .cpp file:

int main(int argc, char **argv) {
  /* code to do SHA1 stuff */
  return 0;
}
