Update GCC #133

Closed samharrison7 closed 5 years ago

samharrison7 commented 6 years ago

Would it be possible to update GCC to 6.3 or later?

alaniwi commented 6 years ago

Sam,

We cannot alter the base gcc package, because it part of the operating system and is already the latest update from the standard RedHat repository. However, I see that the devtoolset-6 suite contains a build of gcc 6.3.1 which is installed into /opt and can coexist on the system with the standard compiler. We need to make a decision whether or not this suite is an appropriate means of providing such add-on packages for the JAP. For the time being have installed gcc 6.3.1 and a number of related packages from devtoolset-6 on the test server jasmin-sci1-test.ceda.ac.uk for you to evaluate, and we will review when we do a later round of JAP updates for installation on the operational systems. To use the packages, type the following command, which will start a shell in which your $PATH is set up to run the the version from devtoolset-6 when you type gcc:

scl enable devtoolset-6 bash

We will leave this issue open for now, and please can you add to it any comments regarding how you get on with using it.

Regards, Alan
