I'm trying to get SDL to work.

[Trey]

We've been using SDL in my computer class for a while now, and I figured that I should try to start using it at home as well. I've already got Dev-C++ on my computer and it works fine, but I can't get my SDL programs to work. I made a code for pong at class, and it worked fine, but when I tried to get the same code to work on my computer at home (brought over on a flash drive) it won't run.
Here's part of the error message:

SDL/SDL.h: No such file or directory.
SDL/SDl_image.h: No such file or directory.

... and then it goes on to not recognize any of my SDL related code.
I don't know what I'm supposed to do, so if anyone has any ideas your comments would be much appreciated!

You need to install the SDL headers (and probably the SDL binaries too) in your MinGW installation before you can compile with it.

Here's everything you need to know to use SDL:
http://lazyfoo.net/SDL_tutorials/index.php

Here is the official documentation:
http://www.libsdl.org/

Follow Lazy Foo's Lesson One --> Windows --> Dev-C++ tutorial to get things set-up so that you can compile.

Hope this helps.

I know this question may sound stupid, but I need to ask: you did install the includes, libs, and DLLs, right?
http://www.libsdl.org/

After that, the includes need to be somewhere where the compiler can find them. For example, "<personal dir>\C++\include\SDL\".
You'd need to tell Dev-C++ that you want GCC to look for headers in "<personal dir>\C++\include\".

Then you need to link to the libs you need (in this case, SDL.lib and SDL_image.lib). These could be in "<personal dir>\C++\lib\". More often than not, linking to libs requires a project.

Finally, you need to place the DLLs somewhere where the OS will find them. This is: a) in the same directory as the program, or b) any of the directories in the PATH environment variable. PROTIP: duplicating the same library for each executable defeats the purpose of having a DLL, so it's easier to put it in c:\windows\system32\ or wherever the directory with that purpose happens to be named in the Windows version in question.

Thanks guys, I'm still trying to get use to SDL, and I wasn't able to get much when I went to the website, so I didn't have all that stuff. That lazyfoo site was very helpful, and I was able to follow most of the steps on setting up SDL, but step 3 says to move a subfolder called bin into the C++ bin folder. But there was no bin subfolder in the zip folder I downloaded on the website, and like I said, I wasn't able to get much from libsdl. I'm sorry if I didn't explain that well, but if you could tell me exactly what you did to get SDL working, maybe that would help.

btw
I was able to follow the rest of the steps, and the "SDL/SDL.h: No such file or directory." error message no longer occurs (but the second one still does).

Follow the same steps that you did for SDL, for SDL_image: http://www.libsdl.org/projects/SDL_image/

I got the same problem, or at least i got a problem with SDL image to. I'm learning how to use SDL by this tutorial: http://lazyfoo.net/SDL_tutorials/index.php. My compiler is dev-cpp.

I have downloaded SDL, and it works correctly. Now i have downloaded the SDL image libary, exactly as the tutorial describes. I have downloaded the files, copied the include files to the include map in dev-cpp. The .dll file is in both the bin map of dev-cpp as in the map where i have my project. I have one sourcefile (main.cpp) in my Win32 GUI project. As paramater i have:

-lmingw32 -lSDLmain -lSDL-ISDL_image

I have included SDL_image.h in my sourcefile.
This is the error i get:

cannot find -lSDL-ISDL_image

I have spend the last hour checking or everyting is at the right location etc., so that wont be the problem. Does anyone know what i'm doing wrong?
