Error while installing delphes

[Sayan]

Upon typing make the following error is being shown in the end:

tmp/examples/CaloGrid.o: In function `main':
CaloGrid.cpp:(.text.startup+0xd62): undefined reference to `TString::TString(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
CaloGrid.cpp:(.text.startup+0xdf3): undefined reference to `TString::TString(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: error: ld returned 1 exit status
Makefile:2320: recipe for target 'CaloGrid' failed
make: *** [CaloGrid] Error 1

p.s.: root is working

Hi,

Did you ever resolve this? I am having the same issue now and would love some advice...

Best,
Michael

Please provide more details about your setup: OS version, C++ compiler version, ROOT version, how ROOT was installed, Delphes version.

Hi there: I am using Root 5.34.36, Ubuntu 16.04.5, gcc 5.4.0, I downloaded root from the compiled binaries on the ROOT website, Delphes 3.4.1

[Pavel Demin]

Thanks for the information. I've just checked the ROOT 5.34.36 binaries at ​https://root.cern.ch/content/release-53436. I don't see any binaries for Ubuntu 16.04 and gcc 5.4. If you're using binaries for Ubuntu 14.04 and gcc 4.8, then they are incompatible with your OS and gcc and that's why you obtain the errors when building Delphes.

I'd suggest you to switch to ROOT 6.12.04. The binaries for Ubuntu 16.04 can be downloaded from ​https://root.cern.ch/content/release-61204.

Dear Pavel,

Thanks for the information. That was the realization I had after sending that message. I wound up going with root 6.08 after some issues with the latest version.

My overall goal is to get pythia and delphes running together and I saw this link: https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/Pythia8

where there is a bit of detail about how to unite the two. However, is there a certain directory in which these commands must be run?

Also, if you could point me to a tutorial (either video or not) of an overview of Delphes, I would sincerely appreciate it. I'm just getting my hands into it for the first time..

Thank you for your help! I'm very grateful.

All the best,
Michael

The Pythia installation commands can be run from any directory.

Other command should be run from the Delphes' source directory. The one that is created when you unpack Delphes-3.4.1.tar.gz.

Also, if you could point me to a tutorial (either video or not) of an overview of Delphes, I would sincerely appreciate it.

As far as I know, all the documentation is in the WorkBook section of the wiki pages and in the publication:
