阅读更多关于 How to obtain readelf and objdump binaries for OS X?

问题 From where can I download readelf and objdump binaries for OS X? I'm trying to get the list of exported functions from an NDK .so library and neither nm nor otool worked for me.

阅读更多关于 Why does my code break when using a hash symbol, instead of a hash string?
