Developer Toolset

Introduction

The developer toolset provides more modern compilers and tools than those provided by the operating system. There are several version of these tools.

Documentation

The release notes and user guide for all versions are here.

Initialisation

Use the following commands on a machine where the toolkit is installed.

For bash shells, do
scl enable devtoolset-7 bash
or
scl enable devtoolset-8 bash
or
scl enable devtoolset-9 bash

For csh/tcsh shells, you have to do something like the following for devtoolset-7 for more recent compilers, substitute 8 or 9 for 7 in the instructions below.

setenv PATH /opt/rh/devtoolset-7/root/usr/bin:$PATH
setenv MANPATH /opt/rh/devtoolset-7/root/usr/share/man:${MANPATH}
setenv LD_LIBRARY_PATH /opt/rh/devtoolset-7/root/lib64:${LD_LIBRARY_PATH}

Version

devtoolset-7, devtoolset-8 and devtoolset-9 are available on selected machines

Testing

gcc --version
or 
gfortran --version

should give a modern version like 7.3.1.

Usage

Use just as you would use other versions of the compilers.

Related Software

Can't think of any at the moment.

Potential Problems

Don't put the initialisation command (scl) in your .bashrc or .cshrc as it will create an infinite series of processes known as a forkbomb! If you want to use these compilers by default, you have to do something like the following:

for bash shells:

source scl_source enable devtoolset-7

for csh/tcsh shells
 
setenv PATH /opt/rh/devtoolset-7/root/usr/bin:$PATH
setenv MANPATH /opt/rh/devtoolset-7/root/usr/share/man:${MANPATH}
setenv LD_LIBRARY_PATH /opt/rh/devtoolset-7/root/lib64:${LD_LIBRARY_PATH}
