Apologies for not being clearer. Yes, the .lib I have is the type designed for dynamic linking with the dependencies being fulfilled by the .dll. I guess what I was really trying to ask was, is there a way to combine the library's .dll into the final mex file so that only one file needs to be distributed. So dpb's comment "I think should be able to extract them w/ the librarian and turn into a static lib???" sounds ideal. What is the librarian?
