I've tried hard to install binutil with HomeBrew onto osx 10.11, finally succeed, but objdump still doesn't work. The response given by terminal is as follow:
MacBook-Pro:~ Mars$ brew install binutils
==> Downloading https://homebrew.bintray.com/bottles/binutils-2.26.el_capitan.bo
Already downloaded: /Library/Caches/Homebrew/binutils-2.26.el_capitan.bottle.tar.gz
==> Pouring binutils-2.26.el_capitan.bottle.tar.gz
/usr/local/Cellar/binutils/2.26: 109 files, 140.3M
MacBook-Pro:~ Mars$ objdump
-bash: objdump: command not found
Anybody can help?
