Following on from my earlier post, for anyone compiling ROIcoin in ubuntu from scratch and using command-line only, here's the process I followed. There may be better miners out there but this works nicely. Some of this is from
https://github.com/ROIcoin/ROIcoinsudo apt-get update
sudo apt-get install checkinstall subversion git git-core
sudo apt-get install libssl-dev libminiupnpc-dev
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install libdb4.8-dev libdb4.8++-dev
sudo apt-get install build-essential libboost-all-dev automake libtool autoconf
sudo apt-get install pkg-config
git clone https://github.com/ROIcoin/ROIcoin ROIcoin
cd ROIcoin
sudo su
./autogen.sh && ./configure --with-gui=no
make
make install
The to run it
ROIcoind -rpcuser=rpc -rpcpassword=1234 -rpcport=3377 -daemon=1 -server=1 -listen=0 -miningaddress=RYR39RF8x65s1U45kKEnh7U16ymJHnYkao -gen
As I mentioned before, listen=0 allows my machine to generate without crashing out because of something I haven't been bothered looking into yet and replace the miningaddress with your own wallet receiving address, assuming you've installed a QT version of the wallet on Windoze or some other OS.
