從原始碼建構 numpy 會導致錯誤的架構

Question

我在 Mac 上從原始程式碼建立 numpy，將其連結到我的 ATLAS 庫。因此，我想按照描述運行它這裡 有這些選項：

export MACOSX_DEPLOYMENT_TARGET=10.10
export CFLAGS="-arch i386 -arch x86_64"
export FFLAGS="-m32 -m64"
export LDFLAGS="-Wall -undefined dynamic_lookup -bundle -arch i386 -arch x86_64"
export PYTHONPATH="/Library/Python/2.6/site-packages/"

但編譯器不喜歡所有這些 arch 標誌並退出：

C compiler: cc -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -arch i386 -arch x86_64 -arch x86_64 -arch i386 -pipe

compile options: '-c'
cc: _configtest.c
cc _configtest.o -L/usr/local/atlas/lib -llapack -lf77blas -lcblas -latlas -o _configtest
ld: warning: ignoring file _configtest.o, file was built for i386 which is not the architecture being linked (x86_64): _configtest.o
Undefined symbols for architecture x86_64:
  "_main", referenced from:
     implicit entry/start for main executable
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status

當刪除 -arch i386 標誌時，我可以使安裝工作：

cc -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -arch x86_64 -pipe

但這會在導入 numpy 時導致錯誤：

>>> import numpy
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/numpy/__init__.py", line 170, in <module>
    from . import add_newdocs
  File "/Library/Python/2.7/site-packages/numpy/add_newdocs.py", line 13, in <module>
    from numpy.lib import add_newdoc

    from .type_check import *

    import numpy.core.numeric as _nx
  File "/Library/Python/2.7/site-packages/numpy/core/__init__.py", line 6, in <module>
    from . import multiarray
ImportError: dlopen(/Library/Python/2.7/site-packages/numpy/core/multiarray.so, 2): no suitable image found.  Did find:
    /Library/Python/2.7/site-packages/numpy/core/multiarray.so: mach-o, but wrong architecture

arch事實上，我的isi386和我的machinea x86_64h。

這是否意味著我安裝了錯誤的 ATLAS 或者我在 numpy 建置中遺漏了某些內容？為什麼我必須傳遞多個-arch標誌？
