==> Pouring gdb-8.1.high_sierra.bottle.tar.gz
==> Caveats
gdb requires special privileges to access Mach ports.
You will need to codesign the binary. For instructions, see:
https://sourceware.org/gdb/wiki/BuildingOnDarwin
On 10.12 (Sierra) or later with SIP, you need to run this:
echo "set startup-with-shell off" >> ~/.gdbinit
==> Summary
? /usr/local/Cellar/gdb/8.1: 53 files, 9.9MB
验证：
输入man gdb

GDB(1) GNU Development Tools GDB(1)
NAME
gdb - The GNU Debugger
SYNOPSIS
gdb [-help] [-nh] [-nx] [-q] [-batch] [-cd=dir] [-f] [-b bps]
[-tty=dev] [-s symfile] [-e prog] [-se prog] [-c core] [-p procID]
[-x cmds] [-d dir] [prog|prog procID|prog core]
DESCRIPTION
The purpose of a debugger such as GDB is to allow you to see what is
going on "inside" another program while it executes -- or what another
program was doing at the moment it crashed.
GDB can do four main kinds of things (plus other things in support of
these) to help you catch bugs in the act:
o Start your program, specifying anything that might affect its
behavior.
o Make your program stop on specified conditions.
