Linking libraries and TSelector

ROOT
1

Hello,
I have a small library of C functions. In the past I have always compiled my ROOT programs, linked the necessary libraries and looped over all events in the following manner:

…
TChain c(“tree”);
c.Add(“files”);
Int_t n_ent = c.GetEntries();
for(Int_t ii=0;ii<n_ent;ii++) {
c.GetEntry(ii);
… Process the event
}

I am now running root 5.22 and would like to use the new ProofLite, and hence need to develop a TSelector. This I have done. When I try to run my program I get the error

Error: tliDcaPoint() declared but not defined test_sel.C:728:

Where tliDcaPoint() is the function being called. I have both a static and shared library, libsmall.a and libsmall.so and have tried both
proof->Exec(“gSystem->AddLinkedLibs(”-L/home/stewartt/Work/charm_eff -lsmall")");
proof->Exec(“gSystem->Load(”/home/stewartt/Work/charm_eff/libsmall.so")");

without any success.

How do I link libraries such that when I call the c.Process(“test_sel.C”) such that the Tselector in test_sel.C can utilize functions in libsmall?

Thanks

Solved the problem by replacing
proof->Exec(“gSystem->Load(”/home/stewartt/Work/charm_eff/libsmall.so")");

with

proof->Exec(".L /home/stewartt/Work/charm_eff/libsmall.so");
