Ok,
~$ git clone git://github.com/Lolcust/GeistGeld
~$ cd GeistGeld/src
~/GeistGeld/src$ make -f makefile.unix
~/GeistGeld/src$ mv bitcoind ~/ggd
~/GeistGeld/src$ cd ~
~$ mkdir .gg
Extract bitcoin.conf from Config+Blockchain to .gg directory
In your favourite text editor, change
printtoconsole=1
to
printtoconsole=0
also change
rpcuser=xxxx
rpcpassword=xxx
to something appropriate,
then
~$ ./ggd -datadir=/home/<your-username-here>/.gg &
to check it's working:
~$ ./ggd -datadir=/home/<your-username-here>/.gg getinfo
That's what I did, I'm no expert!
