How to use GDB Debugger on a macOS?

I am currently using a mid 2012 macbook Pro that is running macOS Mojave version 10.14.5. I am trying to use the GDB debugger for debugging C language code. I've already used Homebrew to install gdb on my computer, however it does not seem to work. Here is the output that I get from the terminal in VSCode:

steelwinds-MacBook-Pro:Chapter05 steelwind$ gdb ex2_dbg.out

I'm not sure if I missed a step or if there is something that I should do instead of using Homebrew, but any advice is helpful.

The hint is this line: please check gdb is codesigned - see taskgated(8)

Because of one of Apple's security features, you will need to codesign GDB. Here's how to do that: "please check gdb is codesigned - see taskgated(8)" - How to get gdb installed with homebrew code signed?
