ROOT Version: v6.20.02
the issue below arises in some python scripts written by a summer student some years ago, as we now migrated it to a centos server … and due to the files we read in written out by root 6.20.2 we need at least this version due to schema evolution.
Thank you a lot in advance for any hints,
PS: I’ll attach the stack trace as file as this form complains about more than 2 links in the post
Stack_Trace.txt (84.0 KB)
the stacktrace shows a crash during the instantiation of ROOT interpreter. That points to a problem with the ROOT installation. Can you run any PyROOT script, or can you use the
root interpreter normally with that ROOT installation?
ooof - you are right!
just running / executing “root”
oh no … running the following i also encounter an issue:

root: /lib64/libstdc++.so.6: version `CXXABI_1.3.8’ not found (required by root)
Mmmh it looks like your ROOT installation is broken.
My best guess is that a system update upgraded the compiler or similar, and ROOT needs a rebuild against the new toolchain.
