Fatal error on lxplus9 with nightlies 2024-09-21

• OS version: Red Hat Enterprise Linux 9.4 (Plow)
• Compiler version: gcc (Spack GCC) 14.2.0

Dear All,

I am experiencing fatal errors using /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh -r 2024-09-21 on lxplus9. Reproducer:

git clone git@github.com:lopezzot/DREndcapTube.git
cd DREndcapTube/
source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh
mkdir build; cd build
cmake -DCMAKE_INSTALL_PREFIX=../install/ ..
make install
cd ../install/
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD/lib64
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD/lib
cd ..
ddsim --steeringFile scripts/steer_e-_10GeV_regexSDAction.py

This dumps

Error in <TInterpreter::AutoParse>: Error parsing payload code for class dd4hep::tools::Evaluator with content:

plus a lot of things like

Error in <TClass::LoadClassInfo>: no interpreter information for class dd4hep::tools::Evaluator is available even though it has a TClass initialization routine.
input_line_45:2:18: error: incomplete type 'dd4hep::tools::Evaluator' named in nested name specifier
 &dd4hep::tools::Evaluator::OK;

The same steps but with source /cvmfs/sw-nightlies.hsf.org/key4hep/setup.sh -r 2024-09-20 work fine instead.

Any help would be great. Thank you.

There seems to be a general issue with the last nightly build. See also discussions in #650 an #649

There is something specifically wrong about lxplus, I don't see any of the problems in the build node and CI also seems to pass in other Key4hep repositories. The issue (I think it's the same for all the affected packages) can be reproduced with:

python -c 'import edm4hep; edm4hep.MCParticle()'

Ok: I think I found it, looking at the stack traces, it's loading some ROOT libraries from /usr/lib64...

A workaround:

export LD_LIBRARY_PATH=/cvmfs/sw-nightlies.hsf.org/key4hep/releases/2024-09-21/x86_64-almalinux9-gcc14.2.0-opt/root/6.32.04-vms5ij/lib:$LD_LIBRARY_PATH

A workaround:

export LD_LIBRARY_PATH=/cvmfs/sw-nightlies.hsf.org/key4hep/releases/2024-09-21/x86_64-almalinux9-gcc14.2.0-opt/root/6.32.04-vms5ij/lib:$LD_LIBRARY_PATH

Indeed this works. Will it be reverted in new nightlies or should I export root this way from now on?

I think we can close this issue. Thank you.

It should be fixed today; at least I can not reproduce the issue anymore on lxplus.
