# Luabind linker errors in win32 application, but not console?.

Hello, I'm having trouble linking Luabind with a MSVC8 win32 project. I've tried everything I could think of, and nothing seems to solve the problem. I've tried both prebuilt Luabind binaries as well as building my own. Both the binaries I've build, and the project I'm building are using Multithreaded Debug DLL as the runtime library. Now the odd thing that I don't understand is that in just a normal console application my Luabind static library links just fine, and the sample program works as intended. However, when I try to link the Luabind binaries with my Win32 framework, using the exact same project settings, I get the following link errors.

If anyone has any suggestions as to what I could try they would be greatly appreciated. I'm so frustrated with this. Everytime I think I have a handle on things, problems like this always prove me wrong.

I've been browsing for lua a lot today and i think i read something about issues when linking lua against dynamic libraries today.
But don't take this to serious, it's been one of a million pieces of information i came over today .. so i might twist some facts.

The library you're linking against is linking against a different version of the runtime libraries than your application is. Build the library to link against the same runtime as your app, otherwise you have to change your app to link against the same runtime the lib is.

You missed the part where I said I was building the Luabind static library and my own project that I'm trying to use with Luabind using the exact same runtime library - Multithreaded Debug DLL.

Which library are you referring to? I have tried to help out on this (we are on the same project team at school) and have run up against the same results. When building the luabind library as a win32 static library, it builds correctly. Then we linked against that with our console test app and it works. Using the same project settings but with a win32 app this time and it gave the above errors.

We've tried changing the runtime library from /MT to /MTd, even tried the dll versions and all we got was a variation on the number of errors.

this is caused by different version of Run time libraries.
Check the user defined libraries you used, and make sure all of them is compiled using the same setting:

* select "Multi-threaded DLL (/MD)" for "Use MFC in a Shared DLL"
* select "Multi-threaded (/MT)" for "Use MFC in a Static Library"
