chainparams.cpp:27:5: error: ‘arith_uint256’ was not declared in this scope
errors for more than just line 27. What I'm doing to put your code into chainparams.cpp, is copy and pasting
https://raw.githubusercontent.com/NicolasChoukroun/altcoin-genesis/master/creategenesis.cpp under all of the #include in chainparams.cpp. There is probably something I'm doing wrong here, and I'm way too new to C++ to know what I'm doing wrong. Any help would be greatly appreciated!
