[Rivet] seg fault in rivet-bootstrap-lcg in lxplus install

[Raghav Kunnawalkam Elayavalli]

Hi Andy,

So like i said, i currently have 2.4.1 working and able to submit batch jobs with it (only with the bootstrap and NOT with the bootstrap-lcg). If you are able to run  in a batch job rivet -a ANALYSIS test.hepmc with the latest installation of rivet, I will gladly use it. Ive been trying to do that and i keep getting the python unknown os or something like that.
I also tried the installation of LCG_85 like i said with the same segfault issue. I will try with your latest bootstrap and see what it gives me.

Maybe this is not for you guys but more for the fastjet team (i also sent them an email)
Im getting another issue at the moment when i load a library from fjcontrib -lRecursiveTools  (which you may remember i was asking you guys in the past). So I have it working on my laptop but when i followed and did the same steps in lxplus i get the following error.

Any ideas?

Hi Raghav,

This is very strange. I just tried the 2.5.0 version of rivet-bootstrap-lcg and it worked fine, giving me a functioning setup. At least it could list analyses without segfaulting.

It's possible that I've got something set by default in my shell environment that helps me, but by default on lxplus I get the same gcc 4.4 and Python 2.6 as you do. Maybe someone else could try to reproduce your problem.

I've just updated the LCG bootstrap script to use LCG_85, a newer GCC and FastJet, etc. This also works for me. Maybe you'd have more luck with that?

To use the normal bootstrap on lxplus and other SL6 systems with an old system compiler you need to set up your environment to use a newer compiler and a version of Python compiled with the same. The LCG bootstrap does this automatically and puts the relevant lines into the env.sh script. From my updated LCG_85 build, the relevant lines are these:

source /cvmfs/sft.cern.ch/lcg/releases/LCG_85/gcc/4.9.3/x86_64-slc6/setup.sh<http://sft.cern.ch/lcg/releases/LCG_85/gcc/4.9.3/x86_64-slc6/setup.sh>
source /cvmfs/sft.cern.ch/lcg/releases/LCG_85/Python/2.7.10/x86_64-slc6-gcc49-opt/Python-env.sh<http://sft.cern.ch/lcg/releases/LCG_85/Python/2.7.10/x86_64-slc6-gcc49-opt/Python-env.sh>

There are other, fancier ways to do it, but hopefully this will help. It's definitely a good idea to use a newer release than 2.4.1 -- at least 2.4.3, please! We will soon be releasing 2.5.1.

Andy

I tried this with LCG_82 and LCG_85 (with appropriately changing the
other locations) and i get the same issues. any ideas whats happening?

I also tried to install rivet with the normal bootstrap and i got an
issue with yoda installation since the default gcc in lxplus is 4.4 and
it doesnt support C++11. so any ideas how i can over come that issue? I
would really like to use something like the herwig bootstrap which
installs all the necessary items.

In the meanwhile should i try to install an older version of rivet? one
that doesnt need c++11?
Again, the whole reason why im using this is so that i can run my rivet
analysis on the lxplus batch system since at the moment (my earlier lcg
installation) doesnt work and gives me weird python errors which even
the cern service desk is having a hard time with.
