If compiling Britcoin 3 from source, you must use Berkeley DB 4 (e.g. 4.8) and not 5.

Here are some sample commands for how to get going on an Ubuntu VPS.  Note that you need over 1GB RAM to compile Britcoin because of the TOR stuff.

sudo apt-get update
sudo apt-get install libevent-dev
apt-get install git

git clone https://github.com/greenmo000/britcoin3.0.git
cd britcoin3.0/src
apt-get install nano
sudo apt-get install gcc
sudo apt-get install openssl
sudo apt-get install libssl-dev
sudo apt-get install g++

cd ~
wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz'
tar -xzvf db-4.8.30.NC.tar.gz
cd db-4.8.30.NC/build_unix/
../dist/configure --enable-cxx
make
sudo make install


# Tell your system where to find db4.8
export BDB_INCLUDE_PATH="/usr/local/BerkeleyDB.4.8/include"
export BDB_LIB_PATH="/usr/local/BerkeleyDB.4.8/lib"
sudo ln -s /usr/local/BerkeleyDB.4.8/lib/libdb-4.8.so /usr/lib/libdb-4.8.so
sudo ln -s /usr/local/BerkeleyDB.4.8/lib/libdb_cxx-4.8.so /usr/lib/libdb_cxx-4.8.so

cd ~/britcoin3.0/src
make -f makefile.unix

./britcoind -daemon

That gives you a suggested username and password.

nano ~/.britcoin/britcoin.conf

Put these in the text file:

rpcuser=that username you just got
rpcpassword=that password you just got


./britcoind -daemon
