Library conflict

The same way you do it for your application. You'll have to open the project settings for the library and choose the runtime library it should use. Then recompile the library before linking it with your application.

Okay, I went back and opened the "msvc8" solution in the angelscript folder. I checked the runtime library, it was set to "Multi-threaded Debug DLL". I made sure I was in debug mode. I compiled the library, then copied it into the VC\lib directory, overwriting the previous instance of "angelscriptd.lib". I then went into the project I'm having problems with that uses angelscript. I set it to "Multi-threaded Debug DLL", and the linker had this to say:

The situation changed. Now for the inverse. :)

Looks like you're linking with wxWidgets as a static library, or maybe you're linking with some other library as well.

Try changing the setting to Debug Single-threaded (non-DLL) for both AngelScript and your application.

AngelCode.com - game development and more - Reference DB - game developer references
AngelScript - free scripting library - BMFont - free bitmap font generator - Tower - free puzzle game

There is no "single-threaded" option. Do you mean "Multi-threaded Debug"?

My options are "Multi-threaded", "Multi-threaded Debug", "Multi-threaded DLL", and "Multi-threaded Debug DLL".
There isn't? Have Microsoft removed that option for MSVC 8.0?

Well, then I suppose you should use "Multi-threaded Debug".

LIBCMTD.lib must be coming from wxWidgets since you set both AngelScript and your application to use "Multi-threaded Debug DLL". Changing to the non-DLL version should work.

Ah! That did it! Thank you so much, WitchLord. I don't know what I'd do without you.
