[Trilinos-Users] linking debug on Windows

Matthew,
My guess is that there are some inconsistent compiler options between the library build and your client project. What is strange about this is that I think the function you are showing is actually an inline function and should not result in any object code that needs to be linked in. My guess is that the libraries were built in release mode so that no object code was created for the inline function and then your client project is being built in debug mode that is expecting the inline function to not be inlined and is expecting to find the object code for this function in the library. I am not sure how you would confirm this with the Windows IDE. On Linux/Unix, I would just dump out the exact compile, archive, and link command lines and use nm and grep to find the link symbols to see what is going on.
Can you show the exact compiler options used to build the Trilinos libraries and your exact compiler options that are being used in your client project? I don't know if you can export this type of info with an IDE but that is the info you need to track this down I suspect.
Cheers,
- Ross
