# walletd - compile and install from github sources

# in this case duckduckcoin, which was forked
# from litecoin, like most other altcoins.
# So this should work for other coins, too.

# I succeeded with this on Ubuntu 12.04 and Debian 7.0 x64

# N.B.: the compilation fails with 500 MB RAM, so start with the
# 10$ droplet (1GB); after the compilation you can resize to 5$
# droplet. If you already have the smallest, power it down,
# resize it to at least 1GB of RAM, and power up again.
# Thanks to btcltcdigger for this hint.

# What?  "droplet"?  Your own server for 5$/month running costs!
# A cheap linux virtual server (VPS) in the cloud, created in 55seconds
# At digital ocean http://tiny.cc/digocean NL USA Singapur
# with code SSD2014 you get 10$ welcome bonus
# Buy 10$ droplet for 1 hour compilation, later downgrade to 5$/month.

# Create droplet. Wait for the email with the root password.
# To connect use ssh / putty.exe (data... auto-login: root)

passwd

sudo -i

# prep the system to be able to git & compile & build
cd ~
apt-get update
apt-get install git screen make automake build-essential libboost-all-dev

# might be necessary for other tools, for this wallet on Debian 7 is not:
# apt-get install yasm binutils libcurl4-openssl-dev openssl libssl-dev





# For some reason, bitcoin is stuck in an old database version,
# which is not supported by newest ubuntu / debian anymore,
# so we get it manually:

# Get db4.8 source, compile and install
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz
tar zxf 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
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
export BDB_INCLUDE_PATH="/usr/local/BerkeleyDB.4.8/include"
export BDB_LIB_PATH="/usr/local/BerkeleyDB.4.8/lib"

# rm -R ~/db-4.8.30.NC*   # perhaps not good to delete?



# EDIT: slower but cheap (free)
# create a SWAP FILE instead of the necessity for 1 MB RAM:
sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile





# Get the wallet sources from github
# and build the headless server daemon "duckduckcoind"
cd ~
git clone https://github.com/duckduckcoin/duckduckcoin
cd ~/duckduckcoin/src
make -f makefile.unix USE_UPNP=-
cp duckduckcoind ..


 

# first time start creates folder wallet & blockchain & config
cd ~
./duckduckcoin/duckduckcoind  # just to create the folder,
# stops with password missing error



# create a config file (copy paste the whole paragraph in one go):

cat << "CONFIG" >> ~/.duckduckcoin/duckduckcoin.conf

# enable RPC
