# Compiling
First, let's make sure everything is clean just out of habit:
```bash
terence:master:/tmp/antlr4 $ ./bild.py clean
bootstrapping; downloading bilder.py
target clean
bild succeeded
```
Compiling the source code is easy:
```bash
terence:master:/tmp/antlr4 $ ./bild.py compile
bootstrapping; downloading bilder.py
target compile
require parsers
build compile
bild succeeded
```
Take a look in the bild.log file that is always produced if you'd like to see precisely what commands were executed and their output:
```bash
terence:master:/tmp/antlr4 $ head bild.log
