Full installation on CentOS

Overview

This page gives some unofficial indication of how to get a full YCM installation on CentOS in terms of installation of dependencies. They are provided on a "best efforts" basis, so your mileage may vary, as they say.

Instructions

CentOS 7 Installation

These instructions come in the form of a gist containing scripts that were used to provision a vagrant VM on CentOS 7.

CentOS 6 Installation

These instructions are much more vague, but include useful references.

• Update your installation

yum update (to centos 6.9)

• Install devtoolset-6 according to: https://www.softwarecollections.org/en/scls/rhscl/devtoolset-6/

   yum install centos-release-scl
   yum install devtoolset-6
   source /opt/rh/devtoolset-6/enable
   yum groupinstall "Development tools"

• Install cmake

  yum install cmake

• Install python33 according to: https://www.softwarecollections.org/en/scls/rhscl/python33/

  yum install python33 python33-devel
  source /opt/rh/python33/enable

• Install EPEL repository

yum install epel-release

• Install golang, node, java, maven

  yum groupinstall "Java Platform"
  yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel
  yum install golang
  yum install nodejs
  yum install maven30
  source /opt/rh/maven30/enable

• Install mono according to: http://www.mono-project.com/docs/getting-started/install/linux/

   yum install mono-core mono-devel

• Install rust according to https://www.rust-lang.org/en-US/install.html

  curl https://sh.rustup.rs -sSf | sh
  source ~/.profile

• Build LLVM from source (yay): http://llvm.org/docs/GettingStarted.html#git-mirror
  • sync at least: llvm (into llvm/). clang (into llvm/tools/clang/)
  • check out the latest released version tag
  • note: this takes forever - i would recommend using github.com/llvm-mirrorinstead (or just grab a source tarball)

    yum install cmake3
    cd llvm
    mkdir build
    cd build
    cmake -G "Unix Makefiles" \
       -DCMAKE_BUILD_TYPE=Release \
       -DCMAKE_INSTALL_PREFIX=`pwd`/../root ../
    make -j 8 ;# wait another lifetime
    make install

• Now, when building YCM, use the following command (adjust paths for your environment):

EXTRA_CMAKE_ARGS="-DPATH_TO_LLVM_ROOT=$HOME/llvm/root" ./install.py --all --system-libclang
