Symbol lookup error in ROOT

[tmishra2018]

Hello,

I am getting some symbol lookup error while running my code in my CMS FNAL account.
Error is below:

=============================================================================

Can anyone please suggest what the issue is.

Thanks in advance.

Can you explain a bit more what is your code (a minimal reproducer is enough) and how you run it. ?

[tmishra2018]

Hi,
I am running it as

root -b -q “FitKer.C+(0, 0, 30, 35, 60,120)”

The file is here :

FitKer.C

[Wile_E_Coyote]

Before executing your “FitKer.C” macro, you must make sure that ROOT loads the shared library which provides:

[...]$ c++filt _ZN11RooDCBShapeC1EPKcS1_R10RooAbsRealS3_S3_S3_S3_S3_S3_
RooDCBShape::RooDCBShape(char const*, char const*, RooAbsReal&, RooAbsReal&, RooAbsReal&, RooAbsReal&, RooAbsReal&, RooAbsReal&, RooAbsReal&)

For example, create a simple “rootlogon.C” file (in your current working directory):

{ // rootlogon.C
  gSystem->Load("/path/to/your/libWithRooDCBShape.so");
}

[tmishra2018]

I have
#include “…/…/…/include/RooDCBShape.h”

in the above code.

and the file exist at that location.
Is it not enough ?

In principle, you should talk to your CMS colleagues about how to properly use / run it.
