fstream/iostream headers

[saai]

I am trying to write some file handling routines for my program, using C++ on slackware 7.0.

I have several function prototypes in my own header file that return an fstream object. My problem is, when I include fstream(.h) or iostream(.h) in the same header file, followed by 'using namespace std;', I get the following error:

In file included from /usr/include/g++-2/iostream.h:31,
from /usr/include/g++-2/fstream.h:30,
from filesystem.h:7, (my file)
from menu.h:12, (my file)
from main.cc:10: (my file)
/usr/include/g++-2/streambuf.h:210: arguments given to macro 'clear'
In file included from /usr/include/g++-2/fstream.h:30,
from filesystem.h:7, (my file)
from menu.h:12, (my file)
from main.cc:10, (my file)
/usr/include/g++-2/iostream.h:186: arguments given to macro 'clear'
/usr/include/g++-2/iostream.h:189: arguments given to macro 'clear'

The file be compiled is main.cc. Does anyone know why this is happening?

Thanks,

How about posting the code in main.cc (specifically line 10, but all of it would be nice if it's not too long)?

Sorry, I should have posted the code in my first post. But anyway, here is part of main.cc, which contains only the main() function, which initalizes ncurses then calls a function declared in menu.h.

#include <stdlib.h>
#include "graphics.h"
#include "input.h"
#include "menu.h" // <<< line 10
#include "log.h"

menu.h contains menu systems and related code, like the main menu of my program. This is menu.h:

#include <stdlib.h>
#include <unistd.h>
#include "graphics.h"
#include "input.h"
#include "filesystem.h" // <<< line 12
#include "monsters.h"

And, in filesystem.h:

#include <fstream.h> // <<< line 7
using namespace std;
#include "log.h"

Every part I listed above is the beginning of each file, they don't start at line 1 because I have commenting above them. Currently no code in filesystem.h is being used by the rest of the program.

int clear(void) from ncurses.h probably conflicts with void clear(iostate) from ios. I'm not sure though.

Try one of the following and see if it helps:
1) don't include the entire std namespace, use just what you need.
2) make a header, eg. ncurses++.h, containing the line

namespace ncurses { #include <ncurses.h> }

In your program, don't use namespace ncurses, but specify the functions explicitely, eg. ncurses::some_function

Hope this helps
