Dice

Java, but worse

Requirements

• The test environment is Ubuntu 16.04 running within Virtualbox
• The following ubuntu packages were installed: m4 clang-3.8 llvm opam ocaml
• The following opam packages were installed: core batteries llvm yojson

How to run the compiler

• Make sure you are running Ubuntu 16.04 or equivalent
• clone the repo:

  $ git clone https://github.com/DavidWatkins/Dice.git
  

• Then install the required packages

  $ sudo apt-get install ocaml ocaml-native-compilers camlp4-extra opam m4 clang-3.8 llvm
  

• Then initialize opam in your home directory

  $ opam init
  $ eval $(opam config env)
  $ opam install core batteries llvm.3.8 yojson ocamlfind
  

• Then go into the Compiler directory and run the build script

  $ cd Dice
  $ make
  

• Write a small Dice program

  class HelloWorld {
  public void main(char[][] args) {
    print("Hello World!");
  }
  }
  

• Compile the code and then run it!

  $ ./dice input.dice
  $ lli input.ll
  Hello World!
  

To test the compiler

• cd into tests and run tester.sh after having compiled the compiler

  $ make test
  

If you get an error: “error: expected value token” from lli

This means your version of lli is probably incorrect. Running “lli –version” should return 3.7, but if it doesn’t:

• Run the following commands to remove the symlink of lli in your /usr/bin directory

  $ sudo rm \usr\bin\lli
  $ ln -s /usr/lib/llvm-3.8/bin/lli /usr/bin/lli
  

• Now you should be able to use lli with the outputted llvm code from dice
