Description Kyrre Ness Sjøbæk 2020-04-21 22:30:04 UTC

Description of problem:
GCC (and maybe also GLIBCXX?) was recently updated for Fedora 31, however the root packages were not rebuilt. This causes a problem when building dictionaries with CLING, causing the error message:

Warning in cling::IncrementalParser::CheckABICompatibility():
Possible C++ standard library mismatch, compiled with __GLIBCXX__ '20200317'
Extraction of runtime standard library version was: '20200408'

This in turn causes the dynamic loading of the ROOT dictionaries to fail.

Version-Release number of selected component (if applicable):
root-6.20.04-1.fc31.x86_64 (and sub-packages)

How reproducible:
Every time.

Steps to Reproduce:
1. Install ROOT with DNF
2. Try to build an application requiring ROOT dictionaries, e.g. BDsim:
http://www.pp.rhul.ac.uk/bdsim/manual/installation.html#python-utilities
3. Building of dicts fail.
4. Running of BDsim application fails with error
Error in <TCling::LoadPCM>: ROOT PCM /home/kyrsjo/code/bdsim/bdsim-install/bin/BDSOutputROOTEventBeamDict_rdict.pcm file does not exist

Actual results:
Build of applications depending on ROOT fails if they use ROOT-dictionaries.

Expected results:
Build is succssfull.

Additional info:
This is a known issue for the ROOT devs, see e.g. https://root-forum.cern.ch/t/warning-in-cling-incrementalparser-checkabicompatibility/19423

There should probably be some exact version number dependency in the package on the as-built libraries...

Also note that the "Component description" in bugzilla for "root" is "The basic required files for the root user's directory", which is the same as for "rootfiles".

Note: The issue during run (step 4 to reproduce) seems to be unrelated to this.

Comment 4 Mattias Ellert 2020-04-25 15:43:37 UTC

Do you get a hard error due to this? Or just a warning?
I can reproduce the warning, but I see no failures.
The HepMC3 package that build a ROOT module is regularly tested in the koschei continuous integration, and doesn't report a build failure, though the warning does appear in the build log.
Rebuilding to get rid of the warning meakes sense, though.

Comment 7 Kyrre Ness Sjøbæk 2020-04-27 11:10:44 UTC

Dear Mattias,
thanks for the update; I tested the version for Fedora 31 and I confirm that the compile warnings went away with this.

Regarding runtime errors, in the meantime I have chased them down a bit further and they were not the cause of my crashes OR caused by this issue. Sorry about barking up the wrong tree here and assigning this bug report a too high severity!

Best regards,
Kyrre Sjøbæk
