Windows Subsystem for Linux (Ubuntu)

The lex and yacc implementation we are going to use, flex and yacc, is much more easier to install on a GNU/Linux environment. For those using Windows 10, please install Windows Subsystem for Linux (WSL) with a Linux distro by following the Installation Guide and Initializing Distro. Unless otherwise specified, all commands in this repository are assumed to be executed on Ubuntu.

Once the environment is ready, we may install the tools to build everything.

sudo apt update # Update available software list
sudo apt install build-essential flex bison # Install compilers, build tools and generators

For your information, the local disks can be accessed under /mnt.

How to use Makefiles

Each project comes with a Makefile that speeds up the build process. Follow the instructions to use make on GNU/Linux:

1. Enter the project directory, e.g. cd practices/lex/echo;
2. Run make;
3. There will be one or more <project>.out (e.g. echo.out) appears in the directory if the project builds successfully. Run ./<project>.out to execute;
4. Run make clean to clear all generated files. Be cautious not to commit any generated files to the repository.
