CentOS is an enterprise-oriented Linux distribution, that means it's focused for stability and security but not necessarily the latest software. With that being said, you cannot currently build Qtum in CentOS 7 following the steps that other more recent distributions can use.
In this document we'll show how to build Qtum in CentOS 7 and produce a static binary which can then be executed on any other Linux distribution, even if it's more recent.
Update Yum repositories
sudo yum update
sudo yum install -y tar unzip git which wget patch make autoconf automake libtool \ epel-release centos-release-scl centos-release-scl-rh finduitls vim mc openssl-devel \ file
yum install -y devtoolset-7-gcc* && \ echo "source scl_source enable devtoolset-7" >> /root/.bashrc source scl_source enable devtoolset-7
Clone Qtum Github source:
git clone --recurse-submodules --depth 1 https://github.com/qtumproject/qtum
cd qtum && make -C depends/ DEPENDS="$(pwd)/depends/x86_64-pc-linux-gnu" ./autogen.sh ./configure --prefix=$DEPENDS make
Please keep in mind, this will produce a static build and it will take longer than a normal build.
