我试图为SciPy编译32位和64位体系结构，因为使用该库的一些应用程序只是一个拱形或另一个，遵循fewSOquestions的建议。这个命令已经在类似的建设工作，我大约两个月前，但现在看来，一些编译共享库都只是针对x86_64的：Pip/easy_install忽略SciPy安装中的ARCHFLAGS？
sudo ARCHFLAGS="-arch i386 -arch x86_64" pip install scipy
我试过这个命令的几个版本，包括在sudo之前设置环境变量，其中包括-m32 -m64在FFlags中，使用OSX命令行工具，完整的Xcode安装，使用clang代替official SciPy install instructions之后的OSX附带的LLVM，easy_install代替pip，甚至./configure'ing分开等，但我似乎无法得到它的工作。奇怪的是，一些公司用这两种架构建设。所以，但有些不是：

是否有可能的差异是我使用的gfortran编译器？根据SciPy文档，我使用brew install gfortran，这应该是很好的。我认为重要的一行是C编译器：clang这条线看起来几乎是相同的，包括两个-arch的。
最后最详细的建设我已经试过了：
sudo env ARCHFLAGS="-arch i386 -arch x86_64" ARCH="i386 x86_64" CC="clang" CXX="clang" FFLAGS="-ff2c -m32 -m64" pip install scipy
有谁有关于如何进一步诊断此建议？
