Build EOS on Ubuntu 16.04

1) sudo apt-get install autoconf

2) sudo apt-get install libtool

3)

  cd ~

  mkdir librarys

  git clone https://github.com/cryptonomex/secp256k1-zkp.git

   cd secp256k1-zkp

   ./autogen.sh

   ./configure

   make

   sudo make install

4) git clone https://github.com/eosio/eos --recursive

5)llvm clang for WASM

mkdir  ~/wasm-compiler

cd ~/wasm-compiler

git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/llvm.git

cd llvm/tools

git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/clang.git

cd ..

mkdir build

cd build

cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=.. -DLLVM_TARGETS_TO_BUILD= -DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly -DCMAKE_BUILD_TYPE=Release ../

make -j4 install

6)

sudo apt-get autoremove cmake

cd ~/librarys

wget https://cmake.org/files/v3.8/cmake-3.8.0-Linux-x86_64.tar.gz

tar zxvf cmake-3.8.0-Linux-x86_64.tar.gz

cd cmake-3.8.0-Linux-x86_64

sudo ln -s ~/librarys/cmake-3.8.0-Linux-x86_64/bin/* /usr/bin/

sudo ldconfig

cmake --version

cmake version 3.8.0

7)

tar zxvf boost_1_64_0.tar.gz

cd boost_1_64_0

./bootstrap.sh

#sudo ./b2 link=shared threading=multi  runtime-link=shared variant=release install

./bjam release install

8)

wget https://www.openssl.org/source/openssl-1.1.0f.tar.gz

tar zxvf openssl-1.1.0f.tar.gz

cd openssl-1.1.0f

./Configure shared linux-x86_64

sudo make install

9)

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt-get update

sudo apt-get install gcc-4.9

sudo apt-get install g++-4.9

装了ppa,各种版本就可以共存了。不过有一个问题，每次要用的时候，必须使用g++-4.9，如果直接用g++会运行4.8版本的，非常麻烦。

所以需要改一下/usr/bin/下的链接。

sudo su

cd ../../usr/bin

ln -s /usr/bin/g++-4.9 /usr/bin/g++ -f

ln -s /usr/bin/gcc-4.9 /usr/bin/gcc -f

10)

sudo apt-get install libbz2-dev

12)

sudo apt-get install zlib1g-dev

mkdir -p eos/build && cd eos/build
