Okay, experimenting with Code::Blocks IDE. I'm just trying to run a basic program. I've fixed all the errors but one, which isn't in my program. It's something to do with the compiler.
The error message I'm getting is

E:/Apps/CodeBlocks/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../crt2.o:crt1.c:(.text+0x167): undefined reference to `___cpu_features_init'
collect2: ld returned 1 exit status
Process terminated with status 1 (0 minutes, 1 seconds)
1 errors, 0 warnings

What does this mean and how do I fix it?

You probably have auto-detected wrong version of GCC in your environment. This can happen if you have Dev-C++ installed. Check "Settings->Compiler and debugger...->Search directories" and "Settings->Compiler and debugger...->Toolchain executables"

if that doesn't solve it; then uninstall dev-c++ and code::blocks
and then re-install code::blocks.

(edit)
what it means is that you are not linking your code with a required library that implements whatever function its balking at.

copy crt1.o/crt2.o from dev-cpp\lib to mingw\lib (or codeblocks\lib ?? if you used "codeblocks+minGW installer")

So sayeth Google.

Well, I'm running Dev-C++ and Code::Blocks off my thumb drive. How does that work for reinstalling?

Okay. So, after much trial and error, I've got rid of that error. But I'm thinking that making images work in Code::Blocks is a little different. I'm using the same game engine/sprite files that I did in the last project, but the game engine is being stubborn and not drawing anything. Is there any special thing I need to do to add pictures to a project in Code::Blocks?

Check the project files for what? And what exactly is a working directory?

I feel like such a noob.

I think I found it, but the graphics still aren't rendering. I can't see your picture to make sure, though.
I went to Project->Properties->Build Targets and changed the "Execution Working Directory" box to the appropriate folder. The image files are in the folder "img" and here's the function call:

SDL_LoadBMP("img/background.bmp")

Is this right?

I'm going to keep messing around with the Sprite class code just in case I screwed something up. Updates in a minute.

School blocks your site and everything from it. That's why I haven't posted on NOGDUS - my proxy doesn't work any more.

Anyway, still not working, so I think I must have screwed something up. Still digging...

Any site that has downloadable content, games, or is even mildly interesting they block. They also have a set few keywords that they look for in site descriptions - I think some part of NOGDUS' signature must have set off the block, because as far as I know I'm the only person that uses it.
The block isn't infallible, though - that's why I can access sites like RPGDX and KingdomRPG from the computer lab. Any site that's been Google Cached, you can access the cache version. And aside from the basic blocks - MySpace, YouTube, etc. - they only block sites that people access from the library and they deem "inappropriate" (i.e. anything you access while they're nearby). But since I never get on RPGDX or my other sites from the library, they don't know that they exist and therefore don't block them.
And yes, the blocking system is screwed up. They have blocked, so far,

- a search engine (SiteFindService)
- several research-critical sites such as Yahoo! News
- THEIR OWN WEB SITE
