Event display error

[J Dutta]

Hi,

I am using root version 5.34/34 and Delphes 3.3.2. I run into the following error while running "make display" for the event display.

Generating tmp/display/DisplayDict.cc

Please let me know how I can resolve this error.

The following error messages show that your ROOT installation doesn't have the required EVE files:

cannot open file "TEveCaloData.h"
cannot open file "TEveElement.h"
cannot open file "TEveTrack.h"

Hi,

I have installed default ROOT software and installed it globally. How do I install these files since they do not seem to have been in my root package?

Thanks & Regards,

Juhi

If I'm not mistaken, the EVE part is built automatically when the required OpenGL libraries are present on the system.

Here are the commands that I use to install ROOT:

yum install subversion file make gcc-c++ gcc binutils libX11-devel libXpm-devel libXft-devel libXext-devel gcc-gfortran openssl-devel pcre-devel mesa-libGL-devel glew-devel ftgl-devel mysql-devel fftw-devel cfitsio-devel graphviz-devel openldap-devel python-devel libxml2-devel gsl-static xrootd-devel qt-devel

version=5.34.34
export ROOTSYS=/nopt/root/root-${version}-sl6_amd64_gcc44

wget http://root.cern.ch/download/root_v${version}.source.tar.gz
tar zxf root_v${version}.source.tar.gz

cd root
./configure linuxx8664gcc --enable-gdml --enable-minuit2 --enable-qt --enable-qtgsi --enable-roofit --enable-table --enable-unuran
make -j 8
make install

Hi,

I reinstalled root with the above commands. It works correctly now. Thank you very much for the help.
