unable to run delphes on a hep file

[anonymous]

Hi Jerome, Pavel and the Delphes team,

I generated an hep file with madgraph + pythia
(ttH, semi-leptonic channel)
I wanted to run Delphes on this file, but I got the following error:

####### Start conversion to TRoot format ########
StdHEP file format detected
This can take several minutes
./Delphes: symbol lookup error: ./Delphes: undefined symbol: _ZN10TDirectory16CurrentDirectoryEv

Do you have any idea of what could be the problem ?
I am using Delphes version 2.0.3

Many thanks,

Pierre

Hi Pierre,

Did you change your root or gcc version recently? If so, I would suggest to rebuild your delphes:

make clean
rm -rf tmp lib
make -j 8

Otherwise, could you give us more details about your OS, ROOT, gcc versions?
