Hoi Concezio, I don't think you need > /afs/slac.stanford.edu/g/babar/package/root/3.01-06/Linux2-gcc-2.95.2 It should be sufficient to have (i.e. set your BFARCH to Linux2) /afs/slac.stanford.edu/g/babar/package/root/3.01-06/Linux2 The installed version of 3.01/06 is by default with gcc-2.95.2. (Except if you are on a RH 7.1 machine, in which case it's 2.96.) Have you tried on SunOS? Cheers, --U.
