Hi there. Can you please paste the code of HDC.sol?

Hi Tim, your intuition was right -- it was a compatibility issue of my contract and the newest solc version.
It had compiled fine in a previous version, but there have been some changes to solidity which broke things.
I checked the contract, and upgraded the syntax, so now things work fine.

I have a suggestion though: can you catch this kind of errors in truffle, and point users to the solution?
Thanks a lot 👍

Hi, I have the same issue, could tell me which change did you have to make ? thanks!

Hi there. This is a super old issue (I apologize) that has likely been fixed in further releases of Truffle or the most recent release of Truffle 2.0. I'm going to close this for housekeeping purposes. However, don't hesitate to check out the Truffle Gitter for more help, or file a new issue if you run into trouble. Cheers!
