ROOT ignoring .rootrc on LXPLUS

ROOT
1

I am trying to run ROOT on CERN LXPLUS. I have a ~/rootlogon.C file and a ~/.rootrc file. In the ~/.rootrc file is the following line:

Rint.Logon: /afs/cern.ch/user/y/yohay/rootlogon.C

I am a CMS member and therefore setup the needed ROOT environment variables from the central installations of CMSSW as in the following:

cd ~/scratch0/CMSSW_4_2_4_patch2/src
cmsenv
root

However, when I call “root” from any directory other than the home directory, the ~/rootlogon.C file is not executed as I would expect from the contents of my ~/.rootrc file. Furthermore, if I am in a directory that has its own rootlogon.C file, the local rootlogon.C file is run, despite the fact that ~/.rootrc supposedly points Rint.Logon to the ~/rootlogon.C. It’s as if ROOT ignores the fact that I have a ~/.rootrc file defined.

This only started happening within the last week or so, but I can’t exactly trace the problem back to a specific action that I took. Has anyone else experienced this problem, and if so, do you have any advice for me on how to get ROOT’s behavior back to normal?

Thanks,

Hi Rachel,

do:

gEnv->Print()

to see which rootrc setting are taken.

Does the cmsenv create an alias for root? Try “alias root”?

After doing gEnv->Print(), I see a huge list of settings, among them these:

Rint.Load: rootalias.C [Global]
Rint.Logon: rootlogon.C [Global]
Rint.Logoff: rootlogoff.C [Global]
Rint.History: /afs/cern.ch/user/y/yohay/.root_hist [Global]

What does [Global] mean?

alias root gives no output.

Thanks,
Rachel
