无法安装橙色：“错误：命令'clang'失败，退出状态为1” [英] Can't install Orange: "error: command 'clang' failed with exit status 1"

问题描述

我试图在我的Mac OS X 10.7.3（Lion）上安装 Orange ，我不断收到使用pip或源代码构建时出现错误。首先，我得到的错误是：

  error：command'gcc-4.0'failed with exit status 1 
  

我有Xcode 4，它与gcc 4.2.1捆绑在一起。所以我安装了 64位/ 32位Python 2.7.3 ，它内置了gcc 4.2。我还尝试使用以下方法覆盖编译器选项：

  export CC = gcc-4.2 
  
 
 
 
但是这产生了一个不同的错误： 
 
 
 没有找到gcc-4.2，使用clang来代替
 ... 
错误：命令'clang'失败，退出状态1 
  
以下是完整的日志：

解决方案
问题解决了：Xcode 4实际上并没有使用gcc-4.2;它带有新的LLVM编译器。
 
 
 
这只是一个问题： 
 
 
  export CC = llvm-gcc-4.2 
 export CXX = llvm-g ++  -  4.2 
  
然后建立橙色。 
I am trying to install Orange on my Mac OS X 10.7.3 (Lion) and I keep getting an error when using either pip or building from source. First, I was getting an error that read:
error: command 'gcc-4.0' failed with exit status 1
I have Xcode 4, which comes bundled with gcc 4.2.1. So I installed 64-bit/32-bit Python 2.7.3, which has gcc 4.2 built in. I also tried to override the compiler choice using:
export CC=gcc-4.2
But this produced  a different error:
gcc-4.2 not found, using clang instead
...
error: command 'clang' failed with exit status 1

解决方案
Problem solved: Xcode 4 doesn't actually come with gcc-4.2; it comes with the new LLVM compilers.

It was just a matter of doing:
export CC=llvm-gcc-4.2
export CXX=llvm-g++-4.2
then building Orange.
