[Caml-list] How to avoid duplicate type declarations in C files with camlidl?

[Caml-list] How to avoid duplicate type declarations in C files with camlidl?

[nick.name]

Hi all, I am stuck with camlidl: I want to declare a struct wich does not go 
in the produced .h file, because I (obviously) want to use the system header 
files. I don't seem to understand how to do so: here's my attempt


quote(h,"#include <sys/types.h>");
quote(h,"#include <dirent.h>");
quote(h,"#include <unistd.h>");

typedef [abstract] void DIR;

struct dirent 
{
  long int d_ino;
  [string] char d_name[256];
};

[unique] DIR * opendir([in,string] char *name);
[unique] struct dirent * readdir([in,ref] DIR *dir);


Written this way, the generated C and the header are wrong, because they 
contain a declaration for "DIR" , wich already exists, however I realize that 
dir is done with a macro. But the generated C source also contains a 
declaration for dirent, and according to the same example in the manual, it 
should not! Can someone show me how to compile and run this simple example? I 
have also tried the tests distributed with camlidl but I get so much 
compilation errors and in such different ways :) that I gave up.

Thanks in advance

Vincenzo
