I am trying to create a meteor dapp that can sign a piece of data and then recover the address it was signed with. When I run the dapp I get this error in the console:
Secp256k1 bindings are not compiled. Pure JS implementation will be used
I believe this is causing issues with web3.eth.sign as I cannot recover the address I signed with using ecrecover in either a contract or from ethereumjs-util.
From this answer https://ethereum.stackexchange.com/a/12684 it appears node version 5 or greater is required however meteor only supports node 4.
Is this error a problem or should I ignore it?
