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.
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
