Compiling Singularity-CE-3.9.2 on CentOS-7


The Official Documentation can be found at https://sylabs.io/guides/3.0/user-guide/installation.html

Prerequisites 1 – Yum

If you are using CentOS, you may want to put the necessary libraries and dependencies in first.

yum install -y && \
yum groupinstall -y 'Development Tools' && \
yum install -y \
openssl-devel \
libuuid-devel \
libseccomp-devel \
wget \
squashfs-tools

Prerequisites 2 – Go

Go to the Download Page https://go.dev/dl/ to download the Linux Version.

Extract the archive you downloaded into /usr/local, creating a Go tree in /usr/local/go.

This step below will remove a previous installation at /usr/local/go, if any, prior to extracting. Please back up any data before proceeding.

% rm -rf /usr/local/go && tar -C /usr/local -xzf go1.17.5.linux-amd64.tar.gz

Add /usr/local/go/bin to the PATH environment variable. You can do this by adding the following line to your $HOME/.profile or /etc/profile (for a system-wide installation):

export PATH=$PATH:/usr/local/go/bin

Verify the Installation with the command

% go version

Compiling Singularity

To download Singularity, do visit the download site. Singularity uses a build system called makeit. mconfig is called to generate Makefile and them make is used to compile and install

% cd singularity
% ./mconfig
 --prefix=/usr/local/singularity-ce-3.9.2
% cd build
% make
% make install

Source bash-completion file

% cp /usr/local/singularity-ce-3.9.2/etc/bash_completion.d/singularity /etc/bash_completion.d/
