Thread: expected unqualified-id before "using" ??

Ok, I'm completly confused by this error.
Here is my main.cpp:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string>
#include <windows.h>
#include <vector>
#include <iostream>
#include <SDL/SDL.h>
#include "map.h"
using std::vector;
SDL_Surface *screen = NULL;

vector<SDL_Surface*> images;

void init_imgs(vector<SDL_Surface*> &i)
{
     SDL_Surface *temp;
     temp = SDL_LoadBMP("img/grass.bmp");
     i.push_back(temp);
     temp = SDL_LoadBMP("img/water.bmp");
     i.push_back(temp);
     SDL_FreeSurface(temp);
}

int main (int argc, char *argv[])
{
    char *msg;
    int done;

    if (SDL_Init (SDL_INIT_VIDEO) < 0)
    {
        sprintf (msg, "Couldn't initialize SDL: %s\n", SDL_GetError ());
        MessageBox (0, msg, "Error", MB_ICONHAND); 
        free (msg);
        exit (1);
    }
    atexit (SDL_Quit);

    /*NOTE: Need a 32x24 array for tiles!*/
    screen = SDL_SetVideoMode (1024, 768, 16, SDL_SWSURFACE | SDL_DOUBLEBUF);
    if (screen == NULL)
    {
        sprintf (msg, "Couldn't set 640x480x16 video mode: %s\n",
          SDL_GetError ());
        MessageBox (0, msg, "Error", MB_ICONHAND); 
        free (msg);
        exit (2);
    }
    SDL_WM_SetCaption ("War of Magic", NULL);
    init_imgs(images);
    Map *abc = new Map("level.txt", images, screen);
    
    done = 0;
    while (!done)
    {
        SDL_Event event;

        /* Check for events */
        while (SDL_PollEvent (&event))
        {
            switch (event.type)
            {
            case SDL_KEYDOWN:
                break;
            case SDL_QUIT:
                done = 1;
                break;
            default:
                break;
            }
        }
    }

    return 0;
}

Now then, I keep getting the error

Code:

expected unqualified-id before "using"
expected "," or ";" before "using"

on the line:

Code:

using std::vector;

I've searched google, google groups, and this board but couldn't find anything that seemed relevent to this problem. Can anybody here help?

Assuming map.h is something you've written, look for missing ; close to the end of it.

> sprintf (msg, "Couldn't initialize SDL: %s\n", SDL_GetError ());
> free (msg);
You didn't even malloc your message, so you should be doing neither of these things.
char msg[1000];
is far simpler, especially if you use snprintf() as well.

Though why not use a std::string to store such things?

I didn't right that part, it's part of the SDL DevPack.

Anyways thanks for the suggestion, I'll go look at map.h. Thanks!
