I was able to get mallet running with the command ./mallet iele -d .

I created a simple contract that works in Remix but when I try to compile the contract using iele I get a Uncaught 'Compiler error: 0\nundefined'

The contract below

pragma solidity ^0.4.0;

contract Inbox {

    string public message;

    function Inbox(string initialMessage) public {
        message = initialMessage;

    function setMessage(string newMessage) public returns(string) {
        message = newMessage;


enter image description here

  • Just a guess: Your setMessage function should return a string but it doesn't return anything.
