[ROOT] The open-command in CINT. A linking problem?

Dear Rooters

Last week, I was really in trouble, because I wanted to open a non-ROOT
binary file in CINT and to fill NTuples with the data.

Finally Michele Weber an me could do it with compiling the ROOT script.
But I am still not able to use the open-command in CINT.

I can compile the following code with my GNU C++ Compiler on SUN SOLARIS
and execute the program also:

---

#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
#include <fcntl.h>

main ()

{  
  int read, error; 
 
  error=open("hello",read,0x100);
  printf("Error: %d\n",error);
}

---

I cannot execute the following ROOT script in CINT:
----
{
gROOT->Reset();


#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

int read, error;  

error=open("hello",read,0x100);
printf("Error: %d\n",error);

}
----

Why? Is it an including and/or linking problem? #include commands inside
{  } look terrrible strange. But #include commands outside {  } aren't
working either. Do I make an other mistake?


Thanks

Christian
