Libstdc++.so.5 conflict

ROOT
1

Hi,

I trying to compile a C++ code but I’m receiving the following message:

/usr/bin/ld: warning: libstdc++.so.5, needed by /afs/cern.ch/sw/lcg/external/root/5.13.04/slc3_gcc323/root/lib/libNew.so, may conflict with libstdc++.so.6

How do I resolve that??

env | grep -i root

Probably the ROOT was compiled with gcc3.2.3 - which uses libstdc++.so.5.0.3.
But you are trying to compile your application with gcc 3.4.6 - which uses libstdc++.so.6.0.3.

You may want either recompile ROOT with your compiler version or switch to gcc3.2 (find it somewhere installed on your system or compile it yourself).
