I just opened up the example project you sent me. In project properties -> Linker -> Input -> Additional dependencies, the files listed should be .lib, not .dll. This is the case even when you build dlls.
When Plplot is built, it creates a series of libs, who's job is simply to load the equivalent dll and pass function calls to that dll. These are commonly referred to as import libraries. They avoid having to call LoadLibrary() and GetProcAddress() in your code to grab the functions from the dll at runtime. I guess, basically, the import libraries contain the calls to LoadLibrary() and GetProcAddress(). There is a StackOverflow question about them at https://stackoverflow.com/questions/3573475/how-does-the-import-library-work-details Try swapping all your filenames from .dll to .lib and see where we gat to there. This may explain the corruption error - VS was loading the files expecting them to be libs, but they weren't.
