I'm basically doing a hello world and linking to a commerical 3rd party library. I've included the header files, linked to their libraries, but I still get linker errors. Are there some possible problems here other than the obvious (e.g. I am 99% sure I'm linking to the correct library). Is there a way to confirm the static libraries I am linking to are 64bit? Is there a way to confirm that the library has the class (and methods) I am expecting it to have?
