Building Ruby on Rails

Below versions of Ruby on Rails are available in respective distributions at the time of creation of these build instructions:

• Ubuntu 16.04 has 4.2.6-1
• Ubuntu 18.04 has 4.2.10-0
• Ubuntu 19.10 has 5.2.2

The instructions provided below specify the steps to build Rails version 6.0.2.1 on Linux on IBM Z for following distributions:

• RHEL (7.5, 7.6, 7.7, 8.0)
• SLES (12 SP4, 15 SP1)
• Ubuntu (16.04, 18.04, 19.10)

General Notes:

• When following the steps below please use a standard permission user unless otherwise specified.
• A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

Step 1: Build Ruby

1.1) Build Ruby

• Building Ruby (For RHEL (7.5, 7.6, 7.7) ,SLES (12 SP4, 15 SP1)) and Ubuntu 16.04

Note: For Ubuntu 16.04, install the following packages before building Ruby: zlib1g-dev libssl-dev libreadline-dev.

1.2) Correct the gem environment for a standard user

• RHEL (7.5, 7.6, 7.7) , SLES (12 SP4, 15 SP1) and Ubuntu 16.04

        export GEM_HOME=/home/<USER>/.gem/ruby
        export PATH=/home/<USER>/.gem/ruby/bin:$PATH

• RHEL 8.0

        export PATH=/home/<USER>/bin:$PATH

Note: Where <USER> is the standard user you are installing under.

Step 2: Installing Ruby on Rails

2.1) Add build dependencies

• RHEL (7.5, 7.6, 7.7)

   sudo yum install -y patch make gcc
  

• RHEL (8.0)

    sudo yum install -y system-rpm-config zlib-devel.s390x zlib.s390x ruby-devel.s390x patch make gcc
  

• SLES (12 SP4, 15 SP1)

   sudo zypper install -y patch make gcc
  

• Ubuntu 16.04

   sudo apt-get update
   sudo apt-get install -y patch git
  

• Ubuntu (18.04, 19.10)

   sudo apt-get update
   sudo apt-get install -y ruby ruby-dev patch make gcc zlib1g-dev
  

2.2) Install Ruby on Rails via gem

• RHEL (7.5, 7.6, 7.7, 8.0) and SLES (12 SP4, 15 SP1)

   gem install rails -v 6.0.2.1
  

• Ubuntu (16.04, 18.04, 19.10)
