Problem compiling a program under mac os X

Hello all,

  in these weeks I'm migrating also to mac os system. I am new to use root under mac os (I have up to this time used root on linux and unix solaris machines).

I have installed root 4.00/06 with fink commander on powerbook with mac os 10.3 (I have installed Developer tools too and more...).

I have the following problems:
1) When I run root at terminal prompt I have :

      nbkloe:~ francesco$ root
      Wait...  launching X11.....
      .... done
     Warning in <TEnvRec::ChangeValue>: duplicate entry 

<Library.TMCParticle=libEGPythia6.so libEG.so libGraf.so> for level 0; ignored

is this a problem?
How can I remove it?

2) Now I woul'd like to run my programs (that I use under Linux and SunOS) also under my new computer (with mac os X), but when I do this after compilation (compilation NO PROBLEM) I have:

nbkloe:~/LLHOOD_nuovometodo/val-06 francesco$ Darwin/Likelihood.exe Fatal in <TFile::TFile>: ROOT system not initialized aborting
Abort trap

There is anyone that can help me ?

  my program are (only a portion how example):

1. Likelihood.cpp:

#include <iostream.h>
#include "TROOT.h"
#include "TObject.h"

void llhood(Double_t ALFA);

int main(int argc, char* argv[])
{

   double ALFA[] = {0.};
   for(Int_t i=0; i<1; i++){

       llhood(ALFA[i]);
   }
   return 0;
}
2) likelihood.cc:

#define res_class_cxx
#include "res_class.h"
#include <iostream.h>
#include "TH1.h"
#include "TFile.h"
#include "TChain.h"

// GLOBAL VARIABLES THAT I MUST USE IN THE FUNCTION IN likelihood.cc TFile *f2 = new TFile("PROVA.root");
TH1D *gen = new TH1D("gen" ,"gen" ,30,0,1); ....
void fcnllhood(...)
{
.......
}

void llhood(Double_t ALFA)
{

   cout<<"SONO IN llhood\n"<<endl;

    gen ->Sumw2();
  ....
   TChain *t = new
TChain("~/LLHOOD_nuovometodo/val06/bunch_4_minuit.root/res");

   t->Add("~/LLHOOD_nuovometodo/val06/bunch_4_minuit.root/res"); ....

   res_class *resc = new res_class(t);

   Int_t nentries = Int_t(t->GetEntries());    Int_t nbytes = 0, nb = 0;

   cout<<nentries<<endl;

   for (Int_t jentry=0; jentry<nentries; jentry++) {

     Int_t ientry = resc->LoadTree(jentry);
     nb = resc->GetEntry(jentry);
     nbytes += nb;
     cout<<"entries = "<<jentry<<endl;
     ....
     gen->Fill(resc->daliz_gen);

   }
   ....
   gen -> Reset();
}

and this is the makefile that I have modifies to use on mac os:

SISTEMA_OPERATIVO = $(shell uname -s)

ROOTCFLAGS    = $(shell /sw/bin/root-config --cflags)
ROOTLIBS      = $(shell /sw/bin/root-config --libs)
ROOTGLIBS     = $(shell /sw/bin/root-config --glibs)

ifeq ($(SISTEMA_OPERATIVO),Linux)
CXX = g++
CXXFLAGS = -g $(ROOTCFLAGS)
DEPEND = $(CXX) -MM
DEL = rm -rf

LD = g++
LDFLAGS = -O3 $(ROOTLIBS) -lMinuit
endif

ifeq ($(SISTEMA_OPERATIVO),SunOS)
...
endif

####THIS IS THE PORTION I HAVE ADD

ifeq ($(SISTEMA_OPERATIVO),Darwin)
CXX = g++
CXXFLAGS = -g -O -pipe -Wall -W -Woverloaded-virtual $(ROOTCFLAGS) DEPEND = $(CXX) -MM
DEL = rm -rf

LD = g++
LDFLAGS = -O4 -O -Xlinker -bind_at_load -flat_namespace $(ROOTLIBS) -lMinuit
endif

SOURCES           := $(wildcard *.cc)
OBJECTS           := $(SISTEMA_OPERATIVO)/$(SOURCES:.cc=.o)
EXESRC            := $(wildcard *.cpp)
EXECUTABLES       := $(SISTEMA_OPERATIVO)/$(EXESRC:.cpp=.exe)

all: $(EXECUTABLES)

$(SISTEMA_OPERATIVO)/%.exe : %.cpp $(OBJECTS); ${LD} $(CXXFLAGS) $< $(OBJECTS) $(LDFLAGS) -o $@

$(SISTEMA_OPERATIVO)/%.o : %.cc; $(CXX) $(CXXFLAGS) -c $< -o $@

$(SISTEMA_OPERATIVO)/%.d : %.cc; $(DEPEND) $(CXXFLAGS) $< > $@

$(SISTEMA_OPERATIVO)/%.d : %.cpp; $(DEPEND) $(CXXFLAGS) $< > $@; sed s/.o:/.exe:/g $@ >tmp.sed; mv tmp.sed $@

clean: ; $(DEL) $(SISTEMA_OPERATIVO)/*.d; $(DEL) $(SISTEMA_OPERATIVO)/*.o; $(DEL) $(SISTEMA_OPERATIVO)/*.exe

include $(SISTEMA_OPERATIVO)/$(SOURCES:.cc=.d) include $(SISTEMA_OPERATIVO)/$(EXESRC:.cpp=.d)

NOTE: the same program run perfectly under Linux RH9.0 with root 4.00/04.

Thanks in advance,
Best regards.
