# Compiler Final Project
###### tags: `compiler`

## Enviroment
### thu VACS (Ubuntu 22.04.2 Long Term Supported)

### 避免 VACS 因待機過久而被收回資源
#### Show Applications → Settings → Power → Power Saving Options → Screen Blank (Change to **Never**)

## RUN
### 首先要有 Root 權限

sudo su


### 創建新的腳本去跑

vim compiler.sh


### vim 裡面放入以下程式

apt update

cd /home/s09350150
apt-get install -y flex bison
apt install -y git
git clone https://github.com/gjlmotea/Compiler-sample.git

cd /home/s09350150/Compiler-sample
lex lex.l
ls
yacc yacc.y
ls
yacc -d yacc.y
cc lex.yy.c y.tab.c -o cpl
./cpl < sample1.c
./cpl < sample2.c
./cpl < sample3.c
./cpl < sample4.c
./cpl < sample5.c
./cpl < sample6.c
./cpl < sample7.c
