Container Image Update 201512-01

We will update our build container image between 26th and 29th Dec.

The goal of this update is fairly simple: setting GCC 4.9.2 as the default version in the container image.

If you want to keep using older versions of GCC, you can do so with update-alternatives as described in our doc.

We’ve finished rolling out this update. Now, gcc 4.9 is the default version.

Please let us know if you find any issues.

Hey guys, been getting this everytime I try to run a test today:

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 50 --slave /usr/bin/g++ g++ /usr/bin/g+±4.9

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 50 --slave /usr/bin/g++ g++ /usr/bin/g+±4.9 returned exit code 2

update-alternatives: error: alternative g++ can’t be slave of gcc: it is a master alternative. Action failed: sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 50 --slave /usr/bin/g++ g++ /usr/bin/g+±4.9

Were there any other changes in the container? I’m seeing builds fail that passed two days ago (straight retry of a passing build), so I’m just trying to track down possible causes.

In general, is there a changelog somewhere for the build container? That would be really useful, since we’ve hit failing builds due to tool version changes several times now, and it’s a pain to pin versions of everything.

@Plummat I thought you don’t have to do update-alternatives anymore to use 4.9. Can you remove them?


Not as far as I know.

In general, is there a changelog somewhere for the build container?

This is a great idea. It’s a bit hard to look but here is the entire change. I’ll post the entire changelog with nice format from the next time.

Changes after installing fortran.
