Problem with different dll types

[M squared]

Currently I have a program that uses libsndfile only. I want to also use sfml with this program, but when I try to use objects from the audio library I get an error that I believe is basically telling me i'm using two different types of dlls.

1>sfml-audio-s.lib(SoundRecorder.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in main.obj
1>sfml-audio-s.lib(AudioDevice.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in main.obj
1>sfml-audio-s.lib(Listener.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in main.obj
1>sfml-system-s.lib(Thread.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in main.obj
1>sfml-system-s.lib(Sleep.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in main.obj
1>sfml-system-s.lib(Platform.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in main.obj
1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library
1>C:\Users\Menart\Documents\Visual Studio 2010\Projects\Science Fair 2012\Debug\Science Fair 2012.exe : fatal error LNK1319: 6 mismatches detected

The problem is I have no idea what I'm supposed to do about it. I only get this error when using the extlib dll openal32.dll. Is there another version I'm supposed to be using or am I screwing something else up?

You're mixing debug and release mode.
You're in debug mode, you can not use the release libraries.

Errrr.... this is all a little foreign to me. So do I need to find a different dll, change a mode setting, or just not use it?

Well then it seems you're lacking some important knowledge on how to use your development tools. This post might give you a bit an insight on how compiler & linker work.

If you've set Visual Studio to debug mode, then you have to link all the SFML modules, that use the -d suffix, like sfml-graphics-s-d.lib.
If you're in release mode, you'll have to link the ones without a suffix (except the -s for static).

Thanks, that post was very informative. I'm in debug mode, but I don't see any other version of the openal32.dll file... Also, when I use this file and the libsndfile-1.dll in another program which is also in debug mode, it works fine.

While using SFML, you won't need to link against OpenAL32 nor libsndfile, they get linked to the sfml-audio. Just make sure to link to sfml-audio-d and you should be fine.

yes but when I did that I got an error saying "openal32.dll not found". I didn't link the dll, i put it in the debug folder. Is that part of my problem? Also, I'm using parts in libsndfile in a way that is independent of sfml. So I'd added the libsndfile dll to my program by itself earlier, and also am using the header file. I don't know if this would affect anything but I thought I should mention it.

Update: I tried creating an new project and copying all my code and such into it and relinking it and that seems to be working. This leads me to wonder if I did something weird to the original project.
