如何在Mac OS X上确定静态库（.a）的目标体系结构？ [英] How do I determine the target architecture of static library (.a) on Mac OS X?

问题描述

我有兴趣验证是否为ARM或Intel构建了一个给定的iPhone静态库。

I'm interested in verifying if a given iPhone static library has been built for ARM or Intel.

这比任何事情都更好奇。是否有某种Mac OS X或BSD特定工具来执行此操作？这个发布给出了一个例子Linux。

It's more curiosity than anything. Is there some kind of Mac OS X or BSD specific tool to do this? This post gives an example in Linux.

推荐答案

另一种选择是 lipo ;它的输出简短且比 otool 更具可读性。

Another option is lipo; its output is brief and more readable than otool's.

例如：

% lipo -info /usr/lib/libiodbc.a 
Architectures in the fat file: /usr/lib/libiodbc.a are: x86_64 i386 ppc
% lipo -info libnonfatarchive.a
input file libnonfatarchive.a is not a fat file
Non-fat file: libnonfatarchive.a is architecture: i386
%
