Xcode在OSX 10.9上安装 - clang：error：没有输入文件 [英] Xcode install on OSX 10.9 - clang: error: no input files

问题描述

我正在将OS X 10.9 Mavericks安装XCode Command Line Tools的过程

我安装成功XCode：

  $ xcode-select -p 
 / Library / Developer / CommandLineTools 
  

但是，当我输入 $ clang 或 $ gcc

  clang：error：no input files 
  

解决方案

如果你只是键入命令没有任何输入文件，那么作为注释，编译器报告一个准确的错误消息。

但是如果你有一个现有的项目，那么你可以看到同样的 clang：error：no input files >

• 在制作完成后移动文件夹/文件项目


• 您的某个文件无法被XCode项目识别


• 您的项目预编译头设置错误（错误的前缀）：
  

  
  

  在Xcode中 Build settings 检查前缀标题的值。
  
  在我看来，你设置为 MySecondTabbApp / MySecondTabbApp-Prefix.pch ，它应该只是 MySecondTabbApp-Prefix.pch

错误是我通过步骤来配置ruby，并被指向另一个页面上的指令，刚刚声明检查 $ gcc 而不是 $ gcc --version 。

显然是新的编码，试图了解更多。

I'm in the process of installing XCode Command Line Tools onto OSX 10.9 Mavericks

I did a successful install XCode:

$ xcode-select -p 
/Library/Developer/CommandLineTools 

However when I type in either $ clang or $ gcc it returns:

clang: error: no input files 

解决方案

If you just type the command without any input files, then as commented, the compiler reports an accurate error message.

But if you have an existing project, then you can see that same "clang: error: no input files" message when:

• you move your folder/files after making the project
• one of your files isn't recognized by the XCode project
• your project pre-compile header settings is wrong (wrong prefix):
  

  In Xcode "Build settings" reviews the value for "Prefix header".
  It seems to me that you have it set to "MySecondTabbApp/MySecondTabbApp-Prefix.pch" and it should be just "MySecondTabbApp-Prefix.pch"

The OP user2925321 comments:

The error was that I was running through steps to configure ruby and was directed to instructions on another page that just stated to check for $ gcc instead of $ gcc --version.
Obviously new to coding, trying to learn more.
