Fail to Compile the Master Branch of FCCAnalyses on LXPLUS8

[amanmdesai]

Hello,

This is to report the failure in compiling the 'master' branch of FCCAnalyses.

Computer: CERN LXPLUS

Steps to Reproduce the Error:

git clone https://github.com/HEP-FCC/FCCAnalyses.git
cd FCCAnalyses
source setup.sh
mkdir build install
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=../install
make install
cd ..

Error

It stops somewhere here:

[  8%] Built target FastJet
Consolidate compiler generated dependencies of target ONNXRuntime
[ 15%] Built target ONNXRuntime
[ 17%] Generating G__FCCAnalyses.cxx, libFCCAnalyses_rdict.pcm, libFCCAnalyses.rootmap

Could you please help me with this?

Hello @amanmdesai,

I'm able to compile the FCCAnalyses the way you describe.

Are you sure you are running in the clean environment? Have you used fccanalyses pin command? What shell do you use?

Hi @kjvbrt

I tried now with LXPLUS7 and it works well with no error. However when I tried to compile the FCCAnalyses with LXPLUS8 I face the above error (I retried now, the same error exists).

Is FCCAnalyses compatible to work with LXPLUS8?

Thanks Aman

Hello @amanmdesai,

the FCCAnalyses is tied to Key4hep stack, which does not support LXPLUS8 at the moment. If you are curious enough you can try to compile the stack on your local machine: https://key4hep.github.io/key4hep-doc/spack-build-instructions-for-librarians/spack-setup.html#configuring-spack

I see. Thanks for your help.

Thanks for the link. Sure, I will check the link and try to compile the stack on my machine.

Thanks Aman

Hi @amanmdesai , I would not recommend compiling the full stack on lxplus. You can use singularity on lxplus8 just to compile fccanalyses with the following recipe:

# in FCCanalysis repo
singularity exec -B$PWD:/repo -B /cvmfs docker://ghcr.io/aidasoft/centos7:latest bash
cd /repo; mkdir build; cd build
cmake .. # -D...
make -j 8 install
# exit container with Ctrl+D
source setup.sh

You can then run the installed FCCAnalysis without needing singularity.

Pulling the image the first time will take a while (up to half an hour) but then it should be reasonably fast.

Thanks for the suggestions @vvolkl
