I need to use on lxplus a root version which use gcc 4.6 as compiler.
In past I was using root 5.34.19 sourcing it from afs, but from when we use cvmfs there are no anymore any root version using gcc4.6, or at least I didn’t found it.
Someone has any idea how could I do?
thanks a lot!
in principle, you can find gcc46 on cvmfs*. The question could be more why you need a compiler released in 2011 and wether you can move to a newer version of gcc (and perhaps ROOT).
Hi, thanks for the reply!
Yes the gcc 4.6 compiler I found it, the problem is that there is not any ROOT version available using this compiler. All the version available start from gcc 4.7.
Unfortunately I need an old ROOT versione because I need it to integrated with GEANT4.9.6 which use gcc 4.6.
You might need to build you own version of ROOT, see https://root.cern.ch/building-root
what is the problem of using a recent LCG stack with a coherent set of packages compiled with a recent gcc including both ROOT and G4?
I need to use G4.9 since the code works with the old version
