Mismatch between Dephes and root version on OSX

[azzi]

Dear Delphes team,
I am trying to run analysis on a Delphes tree using Root.
Problem is that now I have this error message:

root [0] gSystem->Load("libDelphes");
Error in <TMacOSXSystem::Load>: version mismatch, /Users/patriziaazzi/MADGRAPH/MG5_aMC_v2_1_1/Delphes/./libDelphes.so = 53418, ROOT = 53423

I think this happens because I had to upgrade ROOT version (after the yosemite Upgrade). I thought that being the version higher it would be backward compatible. Is there a solution?
Thanks a lot,
Pat

Dear Patrizia,

I'd say that the easiest solution would be to delete and reinstall Delphes.

The following commands should do it:

cd MG5_aMC_v2_1_1

rm -rf Delphes

./bin/mg5

install Delphes

Regards,

Pavel
