SDL final help

[NUj6URfi]

I really can't get sdl to work. Can someone post how to load a jpeg? I am looking for code. No other tutorials give out the code.

You will have to be more specific on what you want to do. Do you want to read a jpeg into a stream? Display it on the screen? Load a jpeg from a website? Im sure if you googled "c++ load jpeg to stream" or "c++ display jpeg" you will find what you need.

Even though you asked specifically for no tutorials you need to check out lazy foo's tutorial, before you dismiss tutorials completely.
http://lazyfoo.net/SDL_tutorials/

Image loading is in the second part...

Dev-c++ can't find ISDLmain.

[NUj6URfi]

bump.

[kevinkjt2000]

Try using a proper main?
int main(int argc, char *argv[])

And try linking to the library?
(make sure these flags are present in the call to the linker)

-lmingw32 -lSDLmain -lSDL -mwindows

[NUj6URfi]

Error:

cannot find -lSDLmain
Everything else was good.

[NUj6URfi]

So I got it to work but the SDL window doesn't show up.

[kevinkjt2000]

Are you going to post your code? Right now there isn't really much help anyone can give you, with the small amount of information you have given.

EDIT: Be sure to check out lazy foo's tutorial if you are using Dev C++ http://lazyfoo.net/SDL_tutorials/lesson01/windows/devcpp/index.php

[NUj6URfi]

Has anyone else had the window not appearing glitch before?

[NUj6URfi]

Okay so the window appears, and now on a different piece of code, my file says sdl.dll stray \144 in program.
And it goes on and on with errors like that. Anyone know how to fix the dll?

[NUj6URfi]

Bump.

[NUj6URfi]

Fine here is my code and the errors. I fixed the issues above and now have new ones.

//Basic libraries
#include <iostream>
#include <string>
#include "SDL.h"

using namespace std;
int i;

int main(int argc, char* args[]) {
     cout << "Welcome to my movie.";
     i = 1;
     if (i == 1) {
     SDL_Surface* frame1 = NULL;
    SDL_Surface* screen = NULL;
    if((SDL_Init(SDL_INIT_EVERYTHING)==-1)) { 
    cout << "Error initiating movie."; }
    screen = SDL_SetVideoMode( 640, 480, 64, SDL_HWSURFACE );
    frame1 = SDL_LoadBMP( "C:\\Users\\User\\Desktop\\Frames\\Frame1.bmp" );
     SDL_BlitSurface( frame1, NULL, screen, NULL );
    SDL_Flip( screen );
    SDL_Delay(2000);
    SDL_FreeSurface( frame1 );
    SDL_Quit();
    return 0;
}
}

I get the errors:

`Uint32' was not declared in this scope
warning: `SDL_InitSubSystem' initialized and declared `extern'
error: `Uint32' was not declared in this scope

[NUj6URfi]

bump.

[kevinkjt2000]

Try #include "SDL/SDL.h"

Notice the slight difference used in including SDL. This example is taken straight from lazy foo's tutorial on setting up Dev C++!!!! Please read it and follow the instructions vary carefully and you will have FAR less problems. http://lazyfoo.net/SDL_tutorials/lesson01/windows/devcpp/index.php

On each of lazy foo's lessons there is a link down at the bottom to download the source code.

[NUj6URfi]

I set dev-c++ up a different way to make it easier. I got SDl included and not by saying SDL/SDl.h. I got the error Library not found when I typed in that. The include isn't the problems, the header or code is.

[kevinkjt2000]

Whatever different way you used to make it "easier" is still causing trouble for you. I would highly recommend following the tutorial. One of the benefits of SDL is it is cross platform, so there should be no difference from system to system. As long as each system has the correct SDL libraries installed, the same code should be able to execute. So if your code has an include line that is not matching something tells me you skipped something during the setup of SDL.

[NUj6URfi]

I tried that and got the errors and I am working with someone else on this project so I moved it to my dropbox. Again, I tried the tutorial and got the same errors. I am not using the .dll because I followed the instructions and it said that there was a ton of stray stuff in the dll which stopped dev-c++ from compiling.

[kevinkjt2000]

Alright just for your sake I am going to take a system that has never had Dev-C++ and install SDL and get a window going. I will let you know how it goes.

EDIT: By following directions exactly I was easily able to get a picture on the screen using Dev-C++ for the first time on a machine that had never had it before. (The only reason it took almost an hour is because I am also at work answering phones and talking to customers.)

[NUj6URfi]

What version of dev-c++? I tried redownloading it. Can you try using my code?
