如何使用终端在 Mac OS X 上运行 C 程序? [英] How to run C program on Mac OS X using Terminal?

问题描述

我是 C 的新手.这是我的你好，世界！"程序.

I am new to C. Here is my "Hello,world!" program.

#include <stdio.h>

int main(void)    
{
  printf("Hello, world!
");
  return 0;
}

在我尝试使用终端运行它后，它说:

After I try to run it using Terminal it says:

MacBook-Pro-MacBook:~ macbook$ /Users/macbook/Desktop/peng/Untitled1
-bash: /Users/macbook/Desktop/peng/Untitled1: Permission denied
MacBook-Pro-MacBook:~ macbook$ 

为什么?

推荐答案

首先将您的程序另存为 program.c.

First save your program as program.c.

现在你需要编译器，所以你需要去App Store并安装Xcode，这是Apple的编译器和开发工具.如何找到App Store?输入 ⌘Space 并开始输入 App Store 并按 Enter<进行 Spotlight Search"/kbd> 当它猜对了.

Now you need the compiler, so you need to go to App Store and install Xcode which is Apple's compiler and development tools. How to find App Store? Do a "Spotlight Search" by typing ⌘Space and start typing App Store and hit Enter when it guesses correctly.

App Store 看起来像这样:

Xcode 在 App Store 上看起来像这样:

Xcode looks like this on App Store:

然后您需要在终端中安装命令行工具.如何启动终端?你需要再做一次 Spotlight Search"，这意味着你输入 ⌘Space 并开始输入 Terminal 并点击当它猜到Terminal时输入.

Then you need to install the command-line tools in Terminal. How to start Terminal? You need to do another "Spotlight Search", which means you type ⌘Space and start typing Terminal and hit Enter when it guesses Terminal.

现在像这样安装命令行工具:

Now install the command-line tools like this:

xcode-select --install

然后您可以通过简单地运行 gcc 来编译您的代码，就像在下一行一样，而无需启动名为 Xcode 的又大又丑的软件开发 GUI:

Then you can compile your code with by simply running gcc as in the next line without having to fire up the big, ugly software development GUI called Xcode:

gcc -Wall -o program program.c

注意:在较新版本的 OS X 上，您将使用 clang 而不是 gcc，如下所示:

Note: On newer versions of OS X, you would use clang instead of gcc, like this:

clang program.c -o program

然后你可以运行它:

./program
Hello, world!

<小时>

如果您的程序是 C++，您可能需要使用以下命令之一:

---

If your program is C++, you'll probably want to use one of these commands:

clang++ -o program program.cpp
g++ -std=c++11 -o program program.cpp
g++-7 -std=c++11 -o program program.cpp
