MinGW "undefined reference" error (c++)
Author
While attempting to compile some source code in MinGW, I got these errors:

Yes, a mouthful.
1) I am able to compile regular console programs.
2) I am able to compile sdl programs.
3) This error occurred when I tried to compile one of my games.
4) The errors do differ from each other slightly.
5) Yes, I did do a lot of searching, but was not able to solve the problem
Here is the command line I used (Sorry if it is something very obvious that's causing this error, I haven't been using MinGW for long):
g++ -Lc:\Python26\libs -lmingw32 -lSDL -lSDLmain -lSDL_image -lSDL_ffmpeg main.cpp button.cpp cleanup.cpp EbClassUnit.cpp ECamera.cpp ECFGParse.cpp ECleanup.cpp EDraw.cpp EFPS.cpp ELoad_Image.cpp EPython.cpp EStartup.cpp sprites.cpp toolshed.cpp update.cpp -o ORR.exe
I don't know if this is the source of your problem, but I read somewhere that the extra SDL libraries need to be linked between SDLmain and SDL. So, in your linking, put SDLmain, all your other SDL libraries (SDL_image, etc.), and then SDL. See if things improve.

I'm afraid I still get the same exact errors.
Yes, I am sure I installed all the libraries properly.
Otherwise I would have tested that first.
Here is the new command_line: g++ -Lc:\Python26\libs -lmingw32 -lSDLmain -lSDL_image -lSDL_ffmpeg -lSDL main.cpp button.cpp cleanup.cpp EbClassUnit.cpp ECamera.cpp ECFGParse.cpp ECleanup.cpp EDraw.cpp EFPS.cpp ELoad_Image.cpp EPython.cpp EStartup.cpp sprites.cpp toolshed.cpp update.cpp -o ORR.exe
Oh, and thanks for the quick reply.

Oh, and thanks for the quick reply.
MinGW is very strict about the ordering of the libraries to link to. Not only they need to be in the right order, like TheBuzzSaw said, but they should be *after* the source code to link to, otherwise there are undefined reference errors, as you saw.
With that in mind, try to change the command line to:
g++ -Lc:\Python26\libs -lmingw32 main.cpp button.cpp cleanup.cpp EbClassUnit.cpp ECamera.cpp ECFGParse.cpp ECleanup.cpp EDraw.cpp EFPS.cpp ELoad_Image.cpp EPython.cpp EStartup.cpp sprites.cpp toolshed.cpp update.cpp -o ORR.exe -lSDLmain -lSDL_image -lSDL_ffmpeg -lSDL
With that in mind, try to change the command line to:
g++ -Lc:\Python26\libs -lmingw32 main.cpp button.cpp cleanup.cpp EbClassUnit.cpp ECamera.cpp ECFGParse.cpp ECleanup.cpp EDraw.cpp EFPS.cpp ELoad_Image.cpp EPython.cpp EStartup.cpp sprites.cpp toolshed.cpp update.cpp -o ORR.exe -lSDLmain -lSDL_image -lSDL_ffmpeg -lSDL

I do remember reading that MinGW is very picky on the ordering.
Anyway, I did try what you suggested.
It reduced the error output.
After going through the errors, the compiler doesn't seem to be including the source files correctly.
Does the order I type the source files into the command line matter?
Why do I ask?
Here are the new errors:

By the way, do any tags exist that have a similar effect to the [spoiler][/spoiler] tags?
Anyway, I did try what you suggested.
It reduced the error output.
After going through the errors, the compiler doesn't seem to be including the source files correctly.
Does the order I type the source files into the command line matter?

By the way, do any tags exist that have a similar effect to the [spoiler][/spoiler] tags?
In your first post, i read errors like this:

This looked like a problem in linking the SDL library. After all, if the compiler reads the SDL header properly, but the library isn't linked, that reference should be undefined. But this time, i see absolutely no relation to SDL with the errors:

There are still undefined references with the Python library. The only Pythong reference i see in your line is "-Lc:\Python26\libs". Is there anything else you should be doing?
Also, have you considered investing time in learning how to make makefiles? At first, they can feel complex, but problems like this can be reduced when you're not doing everything on one line.
"Does the order I type the source files into the command line matter?"
When MinGW goes into main.cpp, it'll look at all the headers main includes to get the definitions of all the functions. Linking, i believe, does not happen until every file has been compiled into an intermediate file format. Therefore, not, i don't think it should matter. Does changing the order of files change anything?

Wow, how did I not notice.
Somehow I forgot to compile EDeclarations.cpp
