Ethereum crowdsale tutorial code doesn't work on remix

Question

I took the crowdsale code from the tutorial, copied the whole contract code and pasted it to remix (with Rinkeby testnet), and I'm getting straight an error:

browser/contract.sol:52:25: ParserError: Expected token Semicolon got 'LParen'
       emit FundTransfer(msg.sender, amount, true);
                        ^

What am I doing wrong?

Answer 1

You are using wrong compiler version. The emit keyword was added in Solidity version 0.4.21 - if you use any version below that you either have to remove the emit keyword (the event should work just fine without it then) or upgrade to a newer version.

Remix should support a recent enough compiler.
