Saving object of my own class in standalone program

ROOT
1

Hi,
Please look at the code below

//myclass.h

#include "TNamed.h"
class myclass: public TNamed
{
 public:
  int a;
  myclass();
  myclass(const char* name);
  ClassDef(myclass,1);
};
//myclass.cc

ClassImp(myclass);
myclass::myclass() {}
myclass::myclass(const char* name){SetName(name);}
//testclass.cc

#include "myclass.cc"
#include "TFile.h"
int main()
{
  static myclass* cuts=new myclass("somename");
   cuts->a=4;
   TFile f("test.root","recreate");
   cuts->Write();
}

And shell commands:

$> rootcint -f dict.cc -c myclass.h
$> g++ -Wall `root-config --libs --cflags` -o testclass testclass.cc dict.cc
$> ./testclass
$> root
root [0] #include "myclass.cc"
root [1] TFile f("test.root");
root [2] gDirectory->ls();
TFile**         test.root
 TFile*         test.root
  KEY: myclass        somename;1
root [3] myclass *m = (myclass*)gROOT->FindObject("somename");
Error in <TBuffer::CheckByteCount>: object of class TNamed read too few bytes: 18 instead of 32

What am i missing?

In the interactive version, instead of #include “myclass.h”, do

root > .L myclass.cc+ root > TFile f("test.root") root > somename.Dump(); //or any other construct
