是否需要main.cpp? [英] Is main.cpp required?

问题描述

我试图用 cmake 编译程序，最终删除了我的 main.cpp 文件，该文件刚刚复合到另一个文件中，文件名为的项目(即，我只是将主要功能剪切并粘贴到了那个项目中).问题是我遇到一个 main.cpp 找不到错误，并且不确定在 C ++ 中是否存在一个称为 main.cpp 的文件.code>是必需的，还是我可以有一个包含不同标题的文件，但包含main函数呢?

I was trying to compile a program with cmake, and I ended up deleting my main.cpp file, which I had just compounded into another file which held the name of my project (i.e., I just cut and pasted the main function into that one). The problem is that I got a main.cpp not found error, and wasn't sure whether or not in C++ a file known as main.cpp is required, or can I have a file with a different title which contains the function main instead?

修改我应该注意，我已经删除了对 main 的任何规范，并重新编译了该程序.

Edit I should note that I have removed any specification to main and have recompiled this program.

推荐答案

否，您不需要名为main.cpp的文件.除非您正在构建应用程序，否则不需要包含main()的文件.也就是说，如果您只是构建函数库或独立的目标文件，则不需要main().

No, you don't need a file named main.cpp. You don't need a file containing main() unless you are building an application. That is, if you were just building a library of functions or a standalone object file you would not require main().
