Build Qtum on CentOS 7

It is quite a pain to build Qtum on CentOS because CentOS provides quite old versions of the boost library. Actually We need to build the boost library manually.

General Prerequisites

Add epel-release repo and install some utils:

sudo yum install epel-release gcc-c++ git

Building Boost

We need boost >= 1.58.0 for Qtum but CentOS 7 only provides boost <= 1.53.0, one way is to build it manually.

First we install some dependencies:

sudo yum install python-devel bzip2-devel

Then we clone the boost library from GitHub:

git clone https://github.com/boostorg/boost.git
cd boost

Checking out a release version and init submodules:

git checkout boost-1.58.0
git submodule update --init --recursive

Building boost:
You may set the --prefix and --libdir to anywhere you like or leave it by default, but then you have to add the libdir into LD_LIBRARY_PATH env when building and running Qtum, which is annoying somehow.

# omit the --libdir option for 32-bit systems
./bootstrap.sh --prefix=/usr --libdir=/usr/lib64
./b2 headers
# you may set -j<N> where N is the core number or thread number of your CPU.
sudo ./b2 -j4 install

Building Qtum

Install dependencies:

sudo yum install libtool libdb4-cxx-devel openssl-devel libevent-devel

If you need to build the qtum-qt GUI, install these:

sudo yum install qt5-qttools-devel protobuf-devel qrencode-devel

Cloning the project and init submodules:

git clone https://github.com/qtumproject/qtum.git
cd qtum
git submodule update --init --recursive

Configuring and building:
If you have installed boost to any location other than /, /usr, /usr/local, you need to indicate the location with --with-boost=/path/to/your/boost, and add /path/to/your/boost/lib into LD_LIBRARY_PATH env

./autogen.sh
./configure
make -j4
