Run ucore_lab on mac

---

This manual will guide you run ucore_lab on macOS Catalina.

First, make sure you have installed Xcode or CommandLineTools.

xcode-select --install

Then install Homebrew. (make sure you are using .., otherwise below opreations will extrrrrrrremely slow.)

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Minimal installation

brew install i386-elf-gdb gdb cgdb qemu

Then you could run ucore_lab.

The following steps are able to explain the changes to the standard code for running on Mac. !!!!!If you use my code, there is no need to make the following changes!!!!!

Debugging ucore_lab needs change every code in Makfile like

TERMINAL        :=gtk-Terminal
$(V)$(TERMINAL) -e "$(bash)"

Into

TERMINAL        :=osascript
$(V)$(TERMINAL) -e 'tell app "Terminal" to do script "cd $(mkdir);$(bash)"'

And add this code on the top of Makefile

mkdir	:=$(shell pwd)/$(lastword $(MAKEFILE_LIST))
mkdir   :=$(shell dirname $(mkdir))

Because the gtk-Terminal is not support for Mac. We use apple script to create another termainal window.
