Its seems to have compiled with no errors
do I need to do anything else to make it install or did it do that in the compiling process?
sorry for all the noobie questions and thank you for your patients and sticking with me you two
well just give it a try

in src folder : ./MetalCoind or something like that .... i think it will end in an error that you need to create a .conf file first

That is correct, you have compiled the metalcoin daemon, it can be used from the terminal.
To use you need to create a metalcoin.conf file (they should give instructions in their ANN) and place it over /home/pi/.metalcoin
after that is done, you can start your daemon in the terminal, go to the folder where metalcoind is at, and start it with ./metalcoind (check capital letters if it has like MetalCoind)
The ROKOS v3 "Core" is getting released in this week, it will include full wallets/nodes for Bitcoin and OKCash (OKCash will be already sync, just start and go)
We will Create a ROKOS v3 "Flavors" to include any extra wallet.
The only requirement to get included
will be to make a donation by their communities or dev teams
to support the ROKOS development.
(All versions of ROKOS are distributed for free to the users)
Will share the invitation to make the requests/participate soon after the V3 "core" release.
