Building OCaml

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

  • RHEL (7.8, 7.9) has 4.05.0
  • RHEL (8.4, 8.6, 8.7) has 4.07.0
  • RHEL (9.0, 9.1) has 4.11.1
  • SLES 12 SP5 has 4.03.0
  • SLES (15 SP3, 15 SP4) has 4.05.0
  • Ubuntu 18.04 has 4.05.0
  • Ubuntu 20.04 has 4.08.1
  • Ubuntu (22.04, 22.10) has 4.13.1

The instructions provided below specify the steps to build OCaml v5.0.0 on Linux on IBM Z for following distributions:

  • RHEL (7.8, 7.9, 8.4, 8.6, 8.7, 9.0, 9.1)
  • SLES (12 SP5, 15 SP3, 15 SP4)
  • Ubuntu (18.04, 20.04, 22.04, 22.10)

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.

Pre-requisites

1. Ensure that GCC and GNU make are installed and up to date:

  • RHEL (7.8, 7.9) 
    sudo subscription-manager repos --enable=rhel-7-server-for-system-z-devtools-rpms
sudo yum install -y git flex bison make wget unzip tar qt5-qtbase-devel texlive devtoolset-7 autoconf automake gcc awk sed diff 
# Enable GCC 7 - The changes are not persistent and this command will need to be re-run every time a new terminal session is started.
scl enable devtoolset-7 bash
  • RHEL (8.4, 8.6, 8.7, 9.0, 9.1) 
    sudo yum install -y gcc make git gawk sed diffutils
  • SLES 12 SP5 
    sudo zypper install -y automake gcc7 git make texinfo libtool pkg-config gcc7-c++
sudo rm -rf /usr/bin/gcc /usr/bin/g++ /usr/bin/cc
sudo ln -s /usr/bin/gcc-7 /usr/bin/gcc
sudo ln -s /usr/bin/g++-7 /usr/bin/g++
sudo ln -s /usr/bin/gcc /usr/bin/cc
  • SLES (15 SP3, 15 SP4) 
    sudo zypper install -y gcc make git gawk sed diffutils
  • Ubuntu (18.04, 20.04, 22.04, 22.10) 
    sudo apt-get update
sudo apt-get -y install gcc make git gawk sed diffutils

2. Download the OCaml source and navigate into the top-level directory:

cd /<source_root>/
git clone https://github.com/ocaml/ocaml.git
cd ocaml
git checkout 5.0.0

Build and Install

1. Configure the build by issuing this command:

./configure --enable-ocamltest

2. Build the bytecode, native-code and fast versions of OCaml compilers:

make

3. Run the test suits (Optional):

make tests

4. Install the OCaml system:

sudo make install

5. Validate installation (Optional):

ocaml --version

The output should be:

The OCaml toplevel, version 5.0.0
