Hi, i am using a small XML library with my game (i gave up on using my friend's code, if you read my other post). I compiled it into a .lib and linked it with my project. But i get link errors: That is a snippet of the link errors, there are more but they are all the same. I tweaked the XML code before i compiled it into the .lib but that shouldn't matter because i made sure i included the modified .h and .lib file in my game project. So i don't see why i am getting these link errors, is it maybe some conflicting settings in Visual Studio? (btw, i am using WinXP, MSVC, and SDL). I tried reading the MSVC help on link error LNK2001 but i don't know where to start, i don't know what could be causing the error. If anyone has the slightest idea on what i have done wrong, or if you would like to see my full code, i would be very grateful. thanks [Edited by - XTAL256 on July 5, 2008 6:21:52 PM]

somewhat unrelated but i added /NODEFAULTLIB:LIBCMT.lib to resolve LNK4098 but it didn't solve my problem. I would post my code but it's a bit messy since i am changing all my code to use the new XML library so i will only post it if anyone would like to see it.

What version of visual studio? I haven't seen that error since VC6...

Honestly, i have no idea why i get errors like that. I don't know what LIBCMT.lib is, probably some sort of C runtime library. I also need to exclude MSVCRT.lib from linking and i don't know why i have to do that either. But that's not really a worry to me, i just include/exclude whatever libraries are needed for the project.

The linker errors you're getting means that the compiler/linker doesn't know where to find the implementation of XMLNode::getAttribute(). Make sure that the library has that function in it, the .lib is linked into the project in your project settings, and the .lib is compiled with the same version of visual studio as your exe.

Yeah, i know all that. That's what i was talking about in my first post. I said "I compiled it into a .lib", so i know that the VS version is the same as my project. "i made sure i included the modified .h and .lib file in my game", so yeah, i did all that. But other than that i don't know what else is wrong.

@hoLogramm: ah, that's another thing i don't know about [embarrass]. I have my game project set as "debug" and use "Multi-threaded Debug DLL (/MDd)". I compiled the XML lib as "release" (since the author says it's a lot faster in release mode) and "Multi-threaded (/MT)". That was already set in the VS project that came with the library code i downloaded. It also has "Function-Level Linking" set (i don't know what that is either). I set the XML project to "Multi-threaded DLL" but it still didn't work. Can i use non-debug runtime with the XML library and use it with my project in "debug" mode?

The problem i see is that you compiled with multi-threaded and multi-threaded dll. Change both to multi-threaded (debug or release) and that should fix your problem.

Is there any reason why i must change them to multi-threaded and not multi-threaded dll? Because after i last posted, i changed the XML lib to match my project's settings (multi-threaded debug DLL) but i still got the link errors. I will try changing both to multi-threaded.

Ok, i changed my game project and the XML lib to multi-threaded (debug and release respectively) and it still doesn't work. I will post the project settings in case there is anther reason why i might be getting this error:
