I've tried just about everything and I've gotten errors compiling, decided to work just via cpu mining and then I get errors saying the config file (which I specified) was not found. >___> Someone needs to come up with a start to finish tutorial. I've been able to get every single other miner to work with a little work, but this one is just a tough nut to crack.
You need reaper.conf and litecoin.conf and if you plan to mine BTC and SLC, you also need bitcoin.conf and solidcoin.conf.
Default config files are in /reaperv13b/ and not in /reaperv13b/build/
cp your executable 'reaper' from 'build' ../ and edit coin specific files.
./reaper.conf looks like this (I deleted 2lines, "mine bitcoin" and "mine solidcoin")
./litecoin.conf looks like this:
