Linker error in VS2010 project

Hi,

We are migrating from VC6.0 workspace to VS2010 solution. We have lot of our own dll's and lib's. we were able to build one of our template library. But when we try to use that library in another project we are getting below linker errors. Note that we are not seeing this when we built this with VC6.0 IDE

It looks like some of your modules were build using different CRT libraries or something described in this MSDN article
