Dear Delhphes Team,

I am facing following problem while compilation of Delphes therough Madgraph Interface (MG5 v2.2.3). I have root 6.04 on my system:

Compiling classes/DelphesTF2.cc
classes/DelphesTF2.cc: In member function ‘Int_t DelphesTF2::DefinedVariable(TString&, Int_t&)’:
classes/DelphesTF2.cc:32:12: error: ‘kVariable’ was not declared in this scope
action = kVariable;

make: * [tmp/classes/DelphesTF2.o] Error 1

Please give some solution.
Thanks.
Cheers,
Siddharth

There are already two tickets about the same problem: #431 and #632.

However, I can't reproduce this problem.

I tried on Linux and MacOSX with pre-built ROOT binaries and building ROOT from sources.

If you could describe the exact steps (starting from the OS and compiler versions) to reproduce this problem, then I could try to reproduce them myself.

Regards,

Pavel

Thanks for the information about your system.

I've just tested Delphes 3.2.0 with ROOT 6.02.05 and ROOT 6.04.00.

With ROOT 6.02.05 everything works.

With ROOT 6.04.00 I can reproduce the problem.

Here are the commands that I used:

cd /work/root/
wget http://root.cern.ch/download/root_v6.04.00.Linux-ubuntu14-x86_64-gcc4.8.tar.gz
tar -zxf root_v6.04.00.Linux-ubuntu14-x86_64-gcc4.8.tar.gz
mv root root_6.04.00
export ROOTSYS=/work/root/root_6.04.00
export PATH=$ROOTSYS/bin:$PATH
export PYTHONPATH=$ROOTSYS/lib:$PYTHONPATH
export LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH

cd /work/delphes/
wget http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.2.0.tar.gz
cd Delphes-3.2.0
make

Looking at the ROOT 6.04 release notes

https://root.cern.ch/root/html604/notes/release-notes.html#tformula

I've found that a new version of the TFormula class was introduced and this version is not backward compatible with the old TFormula class.

As a workaround, I can propose to use Delphes 3.2.0 with ROOT 6.02.
