Hi,
I have just upgraded the SLC from 4.4 to 4.7 on my desktop at CERN and I am having problems trying to run ROOT from an official AFS location in a manner I used to do it on SLC4.4.
First, I setup the environment variables to point to the newest production release of ROOT like this
export ROOTSYS=/afs/cern.ch/sw/lcg/app/releases/ROOT/5.22.00/slc4_ia32_gcc34/root
export PATH=$PATH:$ROOTSYS/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ROOTSYS/lib
Then, I try to run ROOT:
pccit25: ~ [1024]$ root -l -b
/afs/cern.ch/sw/lcg/app/releases/ROOT/5.22.00/slc4_ia32_gcc34/root/bin/root.exe:
error while loading shared libraries: libpcre.so.0: cannot open shared
object file: No such file or directory
I tried to google the problem but only found a solution in case I wanted to build ROOT from sources myself http://root.cern.ch/root/roottalk/roottalk09/0275.html which does not really help in my case.
I also noticed that the `libpcre.so.0’ is related to the PCRE package. Here is the version of it I found on my machine:
pccit25: ~ [1020]$ rpm -qf '/usr/lib64/libpcre.so'
pcre-devel-4.5-4.6
I asked the CERN linux support about it but they responded they would not support ROOT.
Many thanks for any help in advance!
