Prefix the yum command with sudo if necessary.
New since 11.0: The minimum gcc version required to compile the LSST Science Pipelines is gcc 4.8. If you are using our previous factory platform, RedHat/CentOS 6, and you are unable to upgrade to version 7 (which comes with gcc 4.8 as default) consult the section below on upgrading compilers in legacy Linux.
Upgrading compilers for legacy RedHat / CentOS 6¶
The minimum gcc version required to compile the Stack is gcc 4.8. This comes as standard in the LSST “factory” platform, Red Hat / CentOS 7.
On our previous factory platform, Red Hat / CentOS 6, you will need to use a more current version of gcc that what is available with your system. If you can go to Red Hat 7, we recommend that you do; if you cannot, we recommend that you use a newer gcc version for the stack by using a Software Collection (SCL) with a different version of devtoolset. This will enable you to safely use a different version of gcc (4.9) for the stack than that used by your operating system (4.4).
devtoolset-3 (after the installing the standard pre-requisites (above)):
sudo yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm sudo yum install -y https://www.softwarecollections.org/en/scls/rhscl/rh-java-common/epel-6-x86_64/download/rhscl-rh-java-common-epel-6-x86_64.noarch.rpm sudo yum install -y https://www.softwarecollections.org/en/scls/rhscl/devtoolset-3/epel-6-x86_64/download/rhscl-devtoolset-3-epel-6-x86_64.noarch.rpm sudo yum install -y scl-utils sudo yum install -y devtoolset-3
