Error in <TUnixSystem::Load>: version mismatch

[liuda]

Hi,

I use Delphes 3.0.5 implemented in the MadGraph5 to simulate the detector effects, but when I try to read the root file output by Delphes 3.0.5, there is an error:

Error in <TUnixSystem::Load>: version mismatch, /Users/daliuda/Desktop/MadGraph5_v1_5_9/Delphes/libDelphes.so = 53405, ROOT = 53407

Is it really an error? Should I trust the results?

Thanks a lot.

With best wishes,

Da

Hi Da,

I'd say that you are using 2 different versions of ROOT:

• version 5.34.05 when you run MadGraph5
• version 5.34.07 when you run ROOT

I'd suggest to rebuild Delphes with your current ROOT version.

Regards,

Pavel
