Hello everyone,
I've taken a look on the net and I can't find where I went wrong. I'm
trying to change a file which contains all the functions I use on my buttons
to a shared library. I've declared these functions in a personal header file
and then I created a linkdef.h header file.
For now I have something like this:
//*************************in essai1.cxx*************************************
#ifndef _CINT_
#include "TCanvas.h"
#include "essai1.h"
#endif
void clearscreen()
{
gROOT->GetListOfCanvases()->Delete();
}
//***********************in essai1.h*****************************************
void clearscreen();
Int_t numrun;
TCanvas *fcanvhodo1;
//********************in essai1LinkDef.h**********************************
#ifdef _CINT_
#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;
#pragma link C++ function clearscreen;
#pragma link C++ global numrun;
#pragma link C++ global fcanvhodo1;
#endif
but the instruction:
rootcint -f essai1Dict.cxx essai1.h essai1LinkDef.h gives:
Error: No symbol Int_tnumrun in current scope FILE:essai1.h LINE:5
if i change Int_t to int and if I reuse the same instruction I get :
Error: No symbol TCanvas in current scope FILE:essai1.h LINE:6
Error: No symbol fcanvhodo1 in current scope FILE:essai1.h LINE:6
Can anyone help,
Thanks, Primrose
