I have a bunch of static .lib files including mysqlclient.lib, v8_base.lib and mysqlpp.lib that I link into my project, these were all built using Visual Studio 2008, they are built using the /MT runtime library option.

I’ve just tried upgrading to VS2012 and the code compiles fine but when the project get linked I get the following errors (over 500 errors in total):

Do the runtime symbols defined by VS2012’s standard libraries differ from those suplied with VS2008?

    The issue you are seeing is due to differences in the STL and other libraries that come as part of C++. You can try the following linker switch:

    /NODEFAULTLIB[:library]

    when building it on the VS2008 side, if you cannot do that, though, you’re out of luck. Basically what you’d have to do is to get rid of the standard libraries and thus delegate the task of resolving them to the linker that is later using the resulting static .lib.

    I should add that you also need to make sure that you only use features that the recipient libraries know about.
