[Clas_offline] compiling/running gsim on centos62

[Silvia Niccolai]

Hello, 
I have been trying to compile and run gsim on centos62, without success.

I first tried the available executable in the "official" bin directory, but it 
crashes with a segmentation fault.

I then checked out from svn the latest gsim and tried to compile it. The 
gsim packages compiles fine (both at 32 and at 64 bits), but errors arise 
when compiling gsim_int and gsim_bat. I tried at 32 bits first (problems 
of missing libraries, then once I found the right paths to the libraries 
there were errors related with gfortran...) and at 64 bits (all 
cernlib-related errors, which didn't go away no matter which available 
path to cernlibs at 64 bits I tried).

As there is soon to be the migration of the farm to centos62, and several 
analyses of 6 GeV data are still ongoing, it would be really good if we could 
have some tips on how to produce working executables of all the "classic" 6-GeV 
codes (gsim, user_ana, gpp,...) on centos62.

Every suggestion or offer for help is more than welcome.

Thank you very much and best regards, 
Silvia
