Eclipse "Nothing to Build for Project" Error on Build
提问by Tchaikovsky
I realize this has been asked before, on this site and others, but none have provided a satisfactory answer. I'm just starting out with C/C++ and I'm using the Eclipse CDT on Mac. After creating a C project, then creating a source file (with the proper .cpp suffix), and writing a simple "Hello World!" program, I get the following error in the console: "Nothing to build for project [name]". There is nothing wrong with the code, as far as I know.
我意识到以前在本网站和其他网站上曾有人问过这个问题，但没有人提供令人满意的答案。我刚开始使用 C/C++，我在 Mac 上使用 Eclipse CDT。创建一个 C 项目后，然后创建一个源文件（带有正确的 .cpp 后缀），并编写一个简单的“Hello World！” 程序，我在控制台中收到以下错误：“没有为项目 [名称] 构建任何内容”。据我所知，代码没有任何问题。
#include <stdio.h>
int main() {
printf("Hello World");
}
I'm pretty sure there is nothing wrong with the gcc configuration or anything, although I am not entirely certain. The source file is saved and appears to be under the project, so I am not sure how to resolve this particular problem.
我很确定 gcc 配置或任何东西都没有问题，尽管我并不完全确定。源文件已保存并且似乎在项目下，因此我不确定如何解决此特定问题。
Any help is appreciated.
任何帮助表示赞赏。

The project would not build becauseit had the .cpp prefix, which implied a C++ file (in a C project). Everything worked when I changed it to .c.
该项目无法构建，因为它具有 .cpp 前缀，这意味着 C++ 文件（在 C 项目中）。当我将其更改为 .c 时，一切正常。

In case of make error,go to project ->properties->c/c++ build->tool chain editor->select tools and select Cygwin C Compiler for C and Cygwin C++ Compiler for C++
如果出现make错误，进入项目->属性->c/c++构建->工具链编辑器->选择工具并选择Cygwin C Compiler for C和Cygwin C++ Compiler for C++
