compilation of Delphes_V_2.0.3

[christophe.delaere@…]

Hi,

I am unable to compile Delphes 2.0.3 on Fedora release 17 (Beefy Miracle) out of the box. Working in a clean directory, this is what I get:

$ ./configure
Makefile ready
To build Delphes type

make

$ make

Generating tmp/Utilities/ExRootAnalysis/src/BlockClassesDict.cc
Compiling tmp/Utilities/ExRootAnalysis/src/BlockClassesDict.cc

g++: error: tmp/Utilities/ExRootAnalysis/src/BlockClassesDict.: No such file or directory
make: * [tmp/Utilities/ExRootAnalysis/src/BlockClassesDict.] Error 1

I traced the origin of that error to the location of Makefile.arch on my system: ROOT is centrally installed by RPM and the proper path is /usr/share/root/Makefile.arch, which is not foreseen in the Makefile (even defining ROOTSYS to /usr/share/root).

Cheers,
Christophe.

Hi Chris,

Currently makefil.arch is searched in:

-include $(ROOTSYS)/etc/Makefile.arch 
-include $(ROOTSYS)/test/Makefile.arch 

Could you try adding :

-include $(ROOTSYS)/Makefile.arch

in the genmakefile (line 213 I think) While pointing rootsys to /usr/share/root as you did ? Each distribution has its own way of installing root, so we have to update this from time to time...

Thanks,

Jerome

i don't remember if this has been solved: could you confirm ?

Hi,
I'm sorry if I am intervening in the conversation..but I think about having a similar problem.
I am using Delphes-3.0.1 and root_v5.34.05. I got the following error on the terminal..

Generating tmp/classes/ClassesDict.cc
Error: cannot open file "TEveCaloData.h" classes/DelphesCaloData.h:5:
Error: class,struct,union or type TEveCaloDataVec not defined classes/DelphesCaloData.h:7:

Warning: Error occurred during dictionary source generation
!!!Removing tmp/classes/ClassesDict.cc tmp/classes/ClassesDict.h !!!
Error: rootcint: error loading headers...
make: * [tmp/classes/ClassesDict.cc] Errore 1

If you could help me I would be very grateful to you!

It looks like your ROOT installation does not include Graph3D package. If I remember well this package is automatically enabled when building ROOT. But it's possible that your system does not have all the dependencies (most probably OpenGL) for this package.

Could you, please provide some more details on how you installed ROOT and what OS you are using?

[drigo]

Thank You for Your reply.
I built ROOT following the "Location independent installation". am I wrong?

I report here the steps of installation.

Location independent installation

You want to install in a generic directory, depending solely on environment variables PATH and LD_LIBRARY_PATH.

Get the sources of the latest ROOT (see above)
Type the build commands:

cd root
./configure --help
./configure [<arch>] [set arch appropriately if no proper default]
(g)make [or, make -j n for n core machines]

After that I add these commands

export ROOTSYS=/home/....../root
export PATH=$ROOTSYS/bin:$PATH
export LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH

in the file ".bashrc".

---

anything wrong?
Thank You in advance.
Cheers

I forgot about saying you my OS.. It is

Distributor ID: Ubuntu
Description: Ubuntu 12.04.2 LTS
Release: 12.04

thanks.

Using "Location independent installation" is OK.

I'm also installing the following packages before building ROOT:

​http://cp3.irmp.ucl.ac.be/downloads/packages-ub1204.txt

The command to install them is

apt-get --no-install-recommends install `cat packages-ub1204.txt`

and the commands that I'm using to build ROOT are

version=5.34.05
export ROOTSYS=/opt/root/root-${version}

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

cd root
./configure linuxx8664gcc --enable-gdml --enable-ldap --enable-minuit2 --enable-mysql --enable-qt --enable-qtgsi --enable-roofit --enable-table --enable-unuran --enable-xrootd
make
make install

If your Ubuntu is 64-bit, you can try my ROOT binaries

​http://cp3.irmp.ucl.ac.be/downloads/root-5.34.05-ub1204_amd64_gcc46.tgz

Thank you for your help.
Now it works, or better..it seems to work. :)

Best,
F.

[Pavel Demin]

Great!

Which solution you tried prebuilt binaries or ROOT rebuild.

If you have other problems with Delphes, please don't hesitate to contact us.

Hi,

I tried to rebuild ROOT using your advice..It works! Thanks a lot once again!
