Pyraf在OS X上構建錯誤版本的GCC

Question

我通過enthought 7.2軟件包安裝了python 2.7，我一直在嘗試安裝pyraf軟件包，但是每次我嘗試安裝它時，我都會得到以下信息：

copying lib/pyraf/wutil.py -> build/lib.macosx-10.5-x86_64-2.7/pyraf
running build_ext
building 'pyraf.sscanfmodule' extension
creating build/temp.macosx-10.5-x86_64-2.7
creating build/temp.macosx-10.5-x86_64-2.7/src
gcc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -isysroot
/Developer/SDKs/MacOSX10.5.sdk -DNDEBUG -g -O3 -arch x86_64 -isysroot
/Developer/SDKs/MacOSX10.5.sdk
-I/Library/Frameworks/EPD64.framework/Versions/7.1/include/python2.7
-I/usr/X11R6/include
-I/Library/Frameworks/EPD64.framework/Versions/7.1/include/python2.7 -c
src/sscanfmodule.c -o build/temp.macosx-10.5-x86_64-2.7/src/sscanfmodule.o
gcc: error: x86_64: No such file or directory
gcc: error: x86_64: No such file or directory
gcc: error: unrecognized option ‘-arch’
gcc: error: unrecognized option ‘-arch’
error: command 'gcc' failed with exit status 1

所以我認為這是一個體系結構問題，所以我重新安裝了軟件包（i386，XCode），然后得到了這個

running install
running build
running build_py
copying lib/pyraf/svn_version.py -> build/lib.macosx-10.5-i386-2.7/pyraf
running build_ext
building 'pyraf.sscanfmodule' extension
gcc -fno-strict-aliasing -fno-common -dynamic -arch i386 -isysroot         
/Developer/SDKs/MacOSX10.5.sdk -DNDEBUG -g -O3 -arch i386 -isysroot     
/Developer/SDKs/MacOSX10.5.sdk -

I/usr/X11R6/include -
I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -c 
src/sscanfmodule.c -o build/temp.macosx-10.5-i386-2.7/src/sscanfmodule.o
gcc: error: i386: No such file or directory
gcc: error: i386: No such file or directory
gcc: error: unrecognized option ‘-arch’
gcc: error: unrecognized option ‘-arch’

之后，在我看來，真正的問題是gcc版本問題，所以我尋找安裝的所有gcc，發現了這一點：

因此，我決定在.bash_profile文件中的別名行指出正確的gcc版本，但根本沒有用。

我嘗試設置gcc環境並構建pyraf setup.py，並得到以下信息：

Giotto:pyraf-dev Huguito$ export CC=/usr/bin/gcc-4.2

Giotto:pyraf-dev Huguito$ python setup.py build


running build

copying lib/pyraf/svn_version.py -> build/lib.macosx-10.5-i386-2.7/pyraf

/Developer/SDKs/MacOSX10.5.sdk -

I/usr/X11R6/include -

gcc -bundle -undefined dynamic_lookup -g -arch i386 build/temp.macosx-10.5-i386-
2.7/src/sscanfmodule.o -o build/lib.macosx-10.5-i386-2.7/pyraf/sscanfmodule.so
gcc: error: i386: No such file or directory
gcc: error: unrecognized option ‘-arch’
error: command 'gcc' failed with exit status 1

如果我鍵入gcc命令但沒有-arch i386標志：

Giotto:pyraf-dev Huguito$ gcc -fno-strict-aliasing -fno-common -dynamic -isysroot 
/Developer/SDKs/MacOSX10.5.sdk -DNDEBUG -g -O3 -isysroot /Developer/SDKs/MacOSX10.5.sdk 
-I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -
I/usr/X11R6/include -
I/Library/Frameworks/Python.framework/Versions/7.2/include/python2.7 -c 
src/sscanfmodule.c -o build/temp.macosx-10.5-i386-2.7/src/sscanfmodule.o

它似乎可以很好地編譯，但是在重新編譯后會忽略它並且根本不起作用。

試試吧。 從您的Xcode安裝命令行工具。 在Xcode->首選項->下載->組件->命令行工具中
