Can not run example sketch

Hi! I've downloaded .zip from GitHub and added to libraries. Then I just wanted to upload memonic.ino sketch from examples, and got following errors

Thanks for your help!

Thanks! I found a few typos in the definitions of the functions, and fixed them in https://github.com/micro-bitcoin/uBitcoin/commit/f5282af24e65de8511707356fba131a5eb9ed960. It should be good now. Could you re-download the zip and try?
