c++ - How to convert a dynamic dll to static lib?

Question

I write a program helloworld.exe; it depends on a.dll. I don't have the source code of the a.dll, which is a dynamic dll. How can i change it to static library, so I can link it into helloworld.exe?

Answer 1

Sorry, but there's no direct way to do so. A DLL is a fully linked executable format file, where a static library is a collection of separate object files collected together. With a little bit of work, you can convert a static library to a DLL, but doing the reverse is non-trivial (to put it mildly).
