could you be more specific, please
which part ?
i tried to compile headless client on raspberry pi, followed instruction as per wikia; but whenever i did run wallet i got above noted error msg. thn i emptied entire ./HyperStake folder, left wallet.dat, tried to sync with bootstrap but every time i got same error msg. so i quit for time being till weekend.
Hort suggested about flux connector engagement, about which i have no clue what it is!!!
i suggested to do something like what jc12345 did for paycon, one click install with the up-todate bootstrap. especially for raspberry pi users (to save long compilation time)
Sorry I don't have a raspi so I am not much help here. I do know that Hedgehog01 had this same error when he built the XRA wallet, but he sorted through it somehow. I will see if I can track down some details.
