# buZz 23 july 2018 , i live on irc #neoscoin

# send your thanks to NXQGBzgQBi7pcjhYcBg5aA3ue1z2MfX4bB  ;)

# tested on ;
#  - debian jessie (8.x)
#  - ubuntu 16.04
#  - debian stretch (9.x)   (needs libssl1.0-dev)
#  - ubuntu 18.04           (needs libssl1.0-dev)


# first we install some dependancies, you need sudo access for this

sudo apt update 

# you may want to do a sudo apt upgrade here aswell for good measure

sudo apt install build-essential libtool autotools-dev \
automake pkg-config libssl-dev libevent-dev bsdmainutils \
libboost-system-dev libboost-filesystem-dev libboost-chrono-dev \
libboost-program-options-dev libboost-test-dev libboost-thread-dev \
libminiupnpc-dev libzmq3-dev libgmp-dev git screen ca-certificates

# if running stretch or some other distro (ubuntu 18.04) where libssl-dev isnt openssl 1.0 , run this : 
# apt install libssl1.0-dev

# if you also want to compile the Qt5 gui you need the following 

sudo apt install qt5-default libprotobuf-dev qttools5-dev-tools protobuf-compiler

# now we grab & build libDB 4.8

mkdir ~/DB48; cd ~/DB48
wget 'http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz'
tar -xzf db-4.8.30.NC.tar.gz
cd db-4.8.30.NC/build_unix/

# EDIT THIS NEXT LINE TO YOUR USERNAME :)
../dist/configure --enable-cxx --disable-shared --with-pic --prefix=/home/buzz/DB48/

make install
cd ~

# time to grab , configure and compile neos!

git clone https://github.com/neoscoin/neos-core
cd neos-core
./autogen.sh

# a) edit your username into the next line on two places ,  b) disabling tests isnt recommended
LDFLAGS="-L/home/buzz/DB48/lib/" CPPFLAGS="-I/home/buzz/DB48/include/" ./configure --disable-tests

# replace 2 with amount of compile threads you want , assume 1-2GB ram per thread is needed  
# ( to get bragging figures, run 'time make -j2' to measure the time it takes to build on your system )
make -j2

cp src/neosd ~/
cp src/neos-cli ~/

# if you built gui aswell :

cp src/qt/neos-qt ~/

cd ~

# we have neos compiled and 'installed' now!

# the daemon is here ; 

~/neosd 

# it will complain about lacking ~/.neos/neos.conf , make one and add the rpc lines it wants

~/neosd

# example rpc call
~/neos-cli getinfo

# best rpc call ever
~/neos-cli help

# follow the logfile, stop with ctrl-c
tail -f ~/.neos/debug.log

# the QT doesnt require neos.conf to exist
~/neos-qt


# and of course you could move these files somewhere else

mkdir ~/neoscoin
mv neosd ~/neoscoin 
mv neos-cli ~/neoscoin 
mv neos-qt ~/neoscoin
