Re: [Condor-users] condor 6.8.8, 32 and 64 bits : solution

[Nicolas GUIOT <nicolas.guiot@xxxxxxx>]

Hi all,

Peter, you helped me very much, but in my case, the solution is slightly different. In my distribution (debian) , I don't have any 'uname -p' option, but 'uname -m' did the trick : it gives me either i686 or x86_64, so here is the solution : 

I have 2 directories (which are in reality symlinks to the actual version, so that updates will be easier/faster) : 
/nfs/condor_x86_64
/nfs/condor_i686

and my exported values are the following : 
export CONDOR_CONFIG=/nfs/condor_`uname -m`/etc/condor_config
export PATH="$PATH:/nfs/condor_`uname -m`/bin:/nfs/condor_`uname -m`/sbin"

Thank you Peter for your help :)

Nicolas
