Hello everyone,

i have recently built the packages (Root5.34, Pythia etc.) via https://alice-doc.github.io/alice-analysis-tutorial/building/build.html using alidock.
As i try to run a simple code using Pythia6 (here it is):
’ #include “cascadedecayer.hpp”
#include “TPythia6.h”
#include “TLorentzVector.h”
#include “TPythia6Calls.h”
#include “TPythia6Decayer.h”

void cascadedecayer(){

gSystem->Load("libEGPythia6.so");
gSystem->Load("libpythia6.so");

TPythia6 *p6 = TPythia6::Instance();

p6->Initialize("CMS", "p", "p", 13000.);
p6 -> GenerateEvent();

}
’

and it results in the following error:

/persist/sw/slc7_x86-64/ROOT/v5-34-30-alice10-1/bin/root.exe: symbol lookup error: /persist/sw/slc7_x86-64/AliRoot/v5-09-45a-1/lib/libpythia6.so: undefined symbol: pyr_

What could be a reason for this? Were the packages built incorrectly?

Thanks in advance!

@getriy, I will recommend you at the beginning to report issue to people who are maintaining alibuild/alidoc build.

Thank you,
Oksana.
