How do I determine the target architecture of static library (.a) on Mac OS X?
bsd, iphone, linker, macos, universal-binary
Solution
Another option is `lipo`; its output is brief and more readable than `otool`'s.
An example:
% 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
%
Problem
I'm interested in verifying if a given iPhone static library has been built for ARM or Intel. 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.
