Hi,

I’m trying to compile root on fedora32. The compilation fails at the TreePlayer target. Here is the output if I restart the compilation with the target TreePlayer (All the previous compilation states wen fine):

Any idea on how to fix this issue ?

ROOT Version: 6.20.04
Platform: Fedora 32
Compiler: Gcc10


@EmmanuelP we still didn’t build ROOT with gcc 10, so thanks for the report! It is something we should to start to look at…Can I ask you please to open a Jira ticket please?

@vvassilev do you have an idea what can be wrong here (I could try maybe to reproduce it)?

Oksana.

Done: https://sft.its.cern.ch/jira/browse/ROOT-10701

I hope the issue is correctly created, I was confused by the JIRA interface, and created it linked to another unrelated issue. I have deleted the link.

Thanks a lot, everything is fine! We are already looking into problem!

@EmmanuelP Temporary solution: cmake with -Dimt=OFF

Thanks @musinsky, works fine now. I’m disabling imt for now in my build until this issue is fixed.

Could you also try applying the proposed patch in the JIRA issue:
