Undefined symbol and STL dictionary generation in proof-lite

ROOT
1

Dea experts,

I compiled my TSelector analysis module into a shared libruary. I wrote a steering macro to submit a proof-lite job. Here is my steering macro:

void runProofLite{
 TProof* p=TProof::Open("");
 p->Load("libMyAna.so");
 TChain* ch=new TChain("mytree");
  ch->Add("qstar.root");
  ch->SetProof();

  gROOT->Time();
  excitedQAna* ana=new excitedQAna();
  ch->Process(ana);
}

However, I encountered two error messages:

After several try & errors, I could resolved the issues by

  1. Explictely loading the libPhysics.so in my steering macro

void runProofLite{ ... p->Load("/cvmfs/atlas.cern.ch/repo/ATLASLocalRootBase/x86_64/root/5.34.19-x86_64-slc6-gcc4.7/lib/libPhysics.so"); ... }
2. Add following lines to the source codes and rebuild the libMyAna.so

void MyAna::SlaveBegin(Tree*){ ... gInterpreter->GenerateDictionary("vector<vector<int> >", "vector"); ... }
My solutions looks quite ad hoc.
Could you recommend alternative ways by changing some configurations, or some flags in the Makefile?

Look forward to your comments and suggestions.

Hi,

to eliminate the explicit load of the library (or the explicit hidden behind the dictionary generation :wink: ) you could link libPhysics.so to your library directly.

Cheers,
