`GLIBCXX_3.4.22' not found

I encounter the following error when running a binary using ROOT:

/cvmfs/cms.cern.ch/slc6_amd64_gcc530/external/gcc/5.3.0/lib64/libstdc++.so.6: version `GLIBCXX_3.4.22' not found (required by /cvmfs/cms.cern.ch/slc7_amd64_gcc630/cms/cmssw/CMSSW_9_4_11/external/slc7_amd64_gcc630/bin/../../../../../../../slc7_amd64_gcc630/lcg/root/6.10.08-fmblme2/lib/libRIO.so)

see that GLIBCXX_3.4.22 is really missing:

strings /cvmfs/cms.cern.ch/slc6_amd64_gcc530/external/gcc/5.3.0/lib64/libstdc++.so.6 | grep GLIBCXX_3.4.2 

What is libRIO.so?
Why does it require libstdc++ that uses a different architecture?
How to fix?

Please read tips for efficient and successful posting and posting code

Where did you find the instructions to set up that version of ROOT? It’s SLC6 (which is really old), and it’s using a custom built compiler that first needs to set up. Can we maybe find a better binary for you? :slight_smile:

I am working at LXPLUS with CMSSW, where Root is already built in.

Then why would CMSSW set up a ROOT that’s not for CC7 (that’s what lxplus runs on) and with an old compiler? Are you using an old CMSSW? Anyway - your setup is incomplete, you need to set up the GCC that comes with it. Please check with your CMSSW friends!

I had set in a script a reference to an old CMSSW version (architecture slc6_amd64_gcc530). This is now fixed.
