Hi,
I am not sure whether it is revelant or not but in $ROOTSYS/test/Makefile we
use the flag '-bundle' to create the .so file.
You should try to build the Event example and load libEvent to see if it has
the same problem (it it has not the same problem ... then you know what to
do :) ).
Cheers,
Philippe

Subject: Re: [ROOT] Trouble with user libraries under Mac OSX (Darwin)
Hi Rene,
Thanks. Yes, the classes do have the ClassDef stuff:
-------------------------------
#foo.h:
#ifndef FOO
#define FOO
#ifndef ROOT_TObject
#include "TObject.h"
#endif
class Foo : public TObject
{
public:
Foo();
Foo(const Char_t * Name, const Char_t * Title);
virtual ~Foo();
ClassDef(Foo,0)
};
#endif
-----------------------------------------------
#foo.cxx:
#ifndef FOO
#include "foo.h"
#endif
#include <iostream.h>
ClassImp(Foo)
Foo::Foo()
{
//Default constructor.
}
Foo::Foo(const Char_t *name, const Char_t *title):TObject()
{
cout<<name<<endl;
}
Foo::~Foo()
{
}
