Pico Dst error

[Rutik]

Hi Experts,
I have some dst files and when I run PicoDstAnalyzer.C, it gives me the error:

IncrementalExecutor::executeFunction: symbol '_ZN15StPicoDstReader13ReadPicoEventEx' unresolved while linking [cling interface function]!
You are probably missing the definition of StPicoDstReader::ReadPicoEvent(long long).

Please help.
Thanks!

Hi @Rutik!

It seems you have not loaded the shared library that contains the StPicoDstReader. One way to solve it is to load the right shared library with gSystem->Load at the beginning of your script, as explained at the bottom of this manual page:

ROOT macros and shared libraries

However, StPicoDstReader is not part of ROOT but of the software of the STAR collaboration. I’d ask them how to setup the environment to tun the PicoDstAnalyzer.C correctly.

Cheers,
Jonas
