How do I get GDB on m1 Mac?
- To install gdb-apple, run the following command in macOS terminal (Applications->Utilities->Terminal) sudo port install gdb-apple Copy.
- To see what files were installed by gdb-apple, run: port contents gdb-apple Copy.
- To later upgrade gdb-apple, run: sudo port selfupdate && sudo port upgrade gdb-apple Copy.
As with GCC, the easiest way to install GDB is through Homebrew. In a Terminal window, run the command brew install gdb , and wait for it to complete. (As usual, it may ask for your password.) Now, we need to code-sign the GDB executable, so it will be allowed to control other processes, as necessary for a debugger.
I just installed it (gdb 8.0) following this procedure as of today, it works on Mac OS High Sierra 10.13. 2 (17C88). For the latest version "brew install gdb" is fine. However, the steps above will allow you to install older versions which is handy.
If you have installed gdb as explained before (using Homebrew), the path should be: /usr/local/Cellar/gdb/version/bin/gdb (replace version with the actual version of your gdb installation, e.g. /usr/local/Cellar/gdb/8.3/bin/gdb).
Both GDB and LLDB are of course excellent debuggers without doubt. GDB is debugger part of the GNU project created to work along the GNU compiler. LLDB is debugger part of the LLVM project created to work along LLVM compiler. The majority of the commands are the same.
The simplest way to configure and build GDB is to run configure from the `gdb- version-number ' source directory, which in this example is the `gdb-5.1. 1' directory. First switch to the `gdb- version-number ' source directory if you are not already in it; then run configure .
Homebrew is a free and open-source software package management system that simplifies the installation of software on Apple's operating system, macOS, as well as Linux. The name is intended to suggest the idea of building software on the Mac depending on the user's taste.

If you're coming to M1 Mac fresh, without any old projects or profiles, you probably won't notice; Homebrew will work as it always has. But if you're trying to migrate from an Intel Mac you won't be able to just move packages that were once in /usr/local over to /opt/homebrew .
Conclusion. If you're looking to improve your productivity and do more with a Mac, command-line package management is the right direction. Homebrew is one of the best free package managers that is relatively easy to use if you have some experience with Terminal.
Homebrew on its own acts like a command-line App Store. It's safe, if you know what you're downloading. It uses SHA256 to fingerprint the downloaded instructions as a validity / tamper detection verification check. It's open, so you could validate what it's downloading and how it works.
What Does Homebrew Mean? Homebrew is a term used to describe games and other software developed by consumers of proprietary computer hardware platforms, such as game consoles, that have hardware restrictions and are not usually user-programmable.
