version-specific builds

[brucellino]

The configuration matrix for ROOT is quite complex. We don't yet have a plugin that can easily filter out the "wrong" combinations of OS/compiler/ROOT version. I propose as a workaround to

• provide version-specific scripts
• split the ROOT-5 from ROOT-6 builds - creating separate jobs for ROOT-5 and ROOT-6.

In this way, we could probably get them to pass independently and make debugging the builds a bit easier.

yay/nay ?

I agree re the split in builds

[brucellino]

ok, I've created root5-delpoy and renamed root-deploy to root6-deploy.

the jobs are - I THINK ! - configured to be treiggered only if there are changes to the scripts which affect them. IE, if build-5.sh changes, only the root5-deploy job will be triggered.

Furthermore, the matrices have been appropriately reduced, pinning the v6x ersions to the root6 job and vice-versa for v5. The GCC axis has also been pruned, with root 5 only using gcc5 and root6 using gcc5 and 6.

root5 can stay on gcc4.9 only.
as for root6 ja on gcc6 only should be fine.
