Hi.
i was on setup for new environment for cravedigger...
on ubuntun 12 on compiling i get these errors.
some ideas how to solve?

Thanks on my debian everything works fine...
you will first need to install secp256k1 to build deamon, someone posted how to do it. thx to someone.
ooo yea, ill be spending some crave there, hope we got some good crave poker players ...game on
