Error: Symbol myTree is not defined in current scope sphericalLEFS60.cc:14

Hello all,

I'm trying to analyse some data I created in GEANT4 using ROOT and I'm using the ROOT book Trees chapter Example 4: A Tree with an Event Class.

The problem is that it doesn't work as expected. I get the error:
Error: Symbol myTree is not defined in current scope sphericalLEFS60.cc:14: Error: Failed to evaluate myTree->SetCacheSize(100000000)

Whats bugging me here is that: myTree->Print(); works as expected and shows all my tree structure, but other operations in myTree simply don't work (that is, it's not just myTree->SetCacheSize(100000000); that gives my problems it's also many other things, like: TBranch* bEvent = myTree
->GetBranch("EventBranch");) I really don't know what to do, since I cannot
see any problem with the code and it's exactly as the example on the book.

{ // init macro

gROOT->Reset();

 if(!TClassTable::GetDict("hiscaleSimEventTree")) {

gSystem->Load("../libs/libhiscaleSimEventTree.so");

}

 // read the tree file generated in GEANT4

TFile* treeFile = new TFile("sphericalLEFS60.root");

treeFile->ls();

TTree *myTree = (TTree*)treeFile->Get("hiscaleSim");

myTree->Print();

myTree->SetCacheSize(100000000); // or many other stuuf like: TBranch* bEvent = myTree->GetBranch("EventBranch");
