Fortunatly we could use pre-built gccemacs right now.
Those two repos did the greate job for us.
https://github.com/twlz0ne/nix-gccemacs-darwin
https://github.com/twlz0ne/nix-gccemacs-sierra
Here is the tutorial:
nix-env -iA cachix -f https://cachix.org/api/v1/install
cachix use gccemacs-darwin
nix-env -iA emacsGccDarwin -f https://github.com/twlz0ne/nix-gccemacs-darwin/archive/master.zipnix-env -iA emacsGccDarwin -f https://github.com/twlz0ne/nix-gccemacs-darwin/archive/master.zipnix-env -iA cachix -f https://cachix.org/api/v1/install
cachix use gccemacs-sierra
nix-env -iA emacsGccSierra -f https://github.com/twlz0ne/nix-gccemacs-sierra/archive/master.zipnix-env -iA emacsGccSierra -f https://github.com/twlz0ne/nix-gccemacs-sierra/archive/master.zipLaunch emacs from terminal, and you could find related app bundle's path by right click emacs icon in Docker.
It's a hard time to make gccemacs work on MacOS catalina. I've met countless problems by following every tutorials I can get from google. Fortunately I finally get it work!
Hope this tutorial could help you.

Latest doom already support to compile all modules with native-comp.
To do so, upgrade doom to latest version.
doom upgrade
After that, do doom sync to compile all modules.
Run doom env to generate local env file.
Open emacs and feel the performance boost. Enjoy!
So, compilation worked, but now running emacs fails with this:
emacs: dlopen(/usr/local/bin/../lisp/emacs-lisp/eln-x86_64-apple-darwin19.6.0-89a730c11dec204e/lisp-mode.eln, 1): image not foundReally weird.
