How to run g++ from a terminal window on my Mac
提问by ragnarius
I have a simple C++ program that I can compile (g++ from command line) and run from my work-computer but not from my home-computer. I don't know how they differ! They are both macbooks and I have installed iPhone SDK on both.
我有一个简单的 C++ 程序，我可以编译（从命令行使用 g++）并在我的工作计算机上运行，但不能从我的家用计算机上运行。不知道有什么区别！它们都是 macbook，我都安装了 iPhone SDK。
On my home-computer: When I add /Developer/usr/binto my PATHI can run g++ but it cannot include <string>and it does not recognize printfand such functions. What else do I need to do to make g++ work?
在我的家用计算机上：当我添加/Developer/usr/bin到我的计算机时，我PATH可以运行 g++，但它不能包含<string>并且无法识别printf此类功能。我还需要做什么才能使 g++ 工作？

- Install xCode and then close
- Edit your c++ code file (I use Smultron, it is free and good)
- Save your file on Desktop with "cpp" termination
- Suppose you have test.cpp program
- Open Terminal (Applications -> Utilities)
- Change directory with command: cd Desktop
- Now write: g++ test.cpp -o test
- For run your program, in Terminal type: test (only that, without ending cpp!)
- If your program it is well writen, on the desktop appear a new file named test
- Click on it and you have your program running
- That is all!
- 安装 xCode 然后关闭
- 编辑你的 C++ 代码文件（我使用 Smultron，它是免费的而且很好）
- 使用“cpp”终止将文件保存在桌面上
- 假设你有 test.cpp 程序
- 打开终端（应用程序 -> 实用程序）
- 使用命令更改目录：cd Desktop
- 现在写： g++ test.cpp -o test
- 要运行您的程序，请在终端中键入：test（仅此而已，不结束 cpp！）
- 如果你的程序写得很好，桌面上会出现一个名为 test 的新文件
- 单击它，您的程序就会运行
- 就这些！

When you installed Xcode and the iPhone SDK, did you check the box for Unix Development Support? I had a lot of problems with this sort of thing because I didn'tdo that, and the solution was to uninstall the SDK and start again with the box checked.
当您安装 Xcode 和 iPhone SDK 时，您是否选中了 Unix Development Support 复选框？我在这类事情上遇到了很多问题，因为我没有这样做，解决方案是卸载 SDK 并重新开始，选中该框。
