# Build requirements

Install a JAVA compiler and ANT:
```
$ sudo apt-get install default-jdk ant
```

Download the Javacard SDKs into the (empty) directory oracle_javacard_sdks
```
$ git submodule update --init --recursive
```

There is also another component "ant-javacard.jar", which is automatically downloaded during the build process.

# Building CAP files

The build process is started by calling ANT
```
$ ant
