I've searched for tutorials but couldn't find any good ones, so I decided to ask here, how do I set up SDL in Visual C++ 2010 express?

LazyFoo's SDL tutorials: http://lazyfoo.net/SDL_tutorials/index.php

The explanations are very clear and easy to follow. Start with Lesson 1 and you are good to go. If you do not understand any of the steps, just post again to ask.

So I tried lesson 1, all compiles fine.
But when I run the program it's just a black screen without any picture on it, what have I done wrong?

make sure the file hello.bmp exists and is located at the right path.

Its there and in the right path, but It still doesn't work. :c

have you written the code or did you just copy it? It is easy to miss a line. The full source can be downloaded at the bottom of the page. If that source don't work you have probably not set up SDL properly.

I guess I'll go over the setting up part once more.

When I think about it, a blank window sounds more like an error in the code than SDL being not properly set up.
Try add the following code after hello = SDL_LoadBMP( "hello.bmp" ); :
if (!hello)
{
printf("SDL_LoadBMP failed: %s\n", SDL_GetError());
}

SDL_LoadBMP failed: Couldn't open hello.bmp

That's what I got in stdout.

So the problem is that it could not open hello.bmp, most likely because it didn't found it. I don't know what visual c++ use for current directory when running your program. Maybe the file should be located at he project root. If you replace the filename ("hello.bmp") with the full path to the file ("C:\\...\hello.bmp") it should work.

I clicked the properties on hello.bmp, and it said;
Item Type: Does not participate in build

### #13Wooh  Members

I think that just means that visual c++ will not try to compile that file.

### #14xzbobzx  Members

Tried all other options, doesn't do anything... :c

BMP files are binary data, binary data and other data files are never compiled they are just that data.

Make sure that your runtime directory is setup properly in the solution file, by default when launching the exe from the IDE it doesn't start in the same directory as to which it builds, it starts in the solution directory.

1. Right click your project and open properties on it.
2. Go to the debugging item in the tree view
3. Set the working directory to the one where the bmp is located

Worked on titles: CMR:DiRT2, DiRT 3, DiRT: Showdown, GRID 2, theHunter, theHunter: Primal, Mad Max

Also didn't work... :|

If you haven't already, change the path back to just "hello.bmp" (that is, don't use the full path).

Then, check and see what the working directory is set to, as NightCreature83 described. I'm not looking at Visual Studio right now, but the path might be expressed in terms of a macro; if you're not sure how to interpret the path, you could post it here.

Or, you could just try putting the file in a few different directories until you find one that works. A good place to start would probably be the project directory itself (the directory where your source code and so on is).

By default, when you run your program from within the IDE, the working directory is set to "$(ProjectDir)", which is the directory containing the project file and source files. However, if you were to run your program from outside the IDE, then the working directory is the directory of the executable. You can change the working directory of a program by going to the project properties (alt+f7), and changing the "Working Directory" field under "Debugging->General". zlib: eJzVVLsSAiEQ6/1qCwoK i7PxA/2S2zMOZljYB1TO ZG7OhUtiduH9egZQCJH9 KcJyo4Wq9t0/RXkKmjx+ cgU4FIMWHhKCU+o/Nx2R LEPgQWLtnfcErbiEl0u4 0UrMghhZewgYcptoEF42 YMj+Z1kg+bVvqxhyo17h nUf+h4b2W4bR4XO01TJ7 qFNzA7jjbxyL71Avh6Tv odnFk4hnxxAf4w6496Kd OgH7/RxC ### #19xzbobzx Members Posted 03 May 2011 - 10:52 AM I also get this sometimes: LINK : [external drive]\SDL_Tutorial\Debug\SDL_Tutorial.exe not found or not built by the last incremental link; performing full link [external drive] being, of course, my external drive. :| ### #20xzbobzx Members Posted 03 May 2011 - 10:58 AM By default, when you run your program from within the IDE, the working directory is set to "$(ProjectDir)", which is the directory containing the project file and source files.

Ah, ok, so it should work if I placed the 'hello.bmp' in the folder containing the .exe?

Edit: it worked.
