無法安裝橙色：當使用

Question

我想在我的Mac OS X 10.7.3（獅子）安裝Orange：「錯誤命令‘鐺’，退出狀態1失敗」，我不斷收到錯誤或者PIP或從源頭上建設。首先，我得到的錯誤如下：

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

我有Xcode 4，它與gcc 4.2.1捆綁在一起。所以我安裝64-bit/32-bit Python 2.7.3，其內置了GCC 4.2我也嘗試過使用覆蓋編譯器的選擇：

export CC=gcc-4.2 

但是，這產生了不同的錯誤：

gcc-4.2 not found, using clang instead 
... 
error: command 'clang' failed with exit status 1 

以下是完整的日誌：

Answer 1

問題解決：Xcode 4實際上並沒有配合gcc-4.2;它配備了新的LLVM編譯器。

這僅僅是一個做的事：

export CC=llvm-gcc-4.2 
export CXX=llvm-g++-4.2 

然後建立橙色。

Answer 2

從http://orange.biolab.si/forum/viewtopic.php?f=4&t=1568

export CC=gcc 
export CXX=g++ 
pip install orange # for example 

似乎更健壯沒有進入版本號的詳細信息，如果你沒有，對不對？ （我沒有之前做這樣的事情，所以我不知道。）

更新：本pip install orange例子（如上圖）目前installs an older version of Orange (version 2.5a4) instead of 2.6。要獲得開發版本，請使用：

pip install -e hg+https://bitbucket.org/biolab/orange#egg=Orange 

我從here得到了上述命令。
