如何使用Visual Studio在C中引用/包括外部源文件/库？

Question

Trying to create a C project that references this so that I could use it in my own application. Unfortunately I'm having a bit of trouble. I'm a C# programmer and in that language it is very simple. First you reference the library and then you use the using keyword.

However, considering I have never programmed in C before I'm having a bit of trouble with this simple task. I tried just copy and pasting all the source files in to my project directory where my main class was also stored but it still couldn't be found. I also tried including the compiled DLL but got the same error:

error C1083: Cannot open include file: 'mpir.h': No such file or directory

I'm reading the documentation for it and it says to only do this at the top of your source file:

#include <mpir.h>

Which is what I'm doing but it does not seem to be working.. Any suggestions?

Answer 1

If mpir.h is in the same directory as your source file, you need to use the include directive with quotations instead of brackets, like this:

#include "mpir.h"

Take a look at Wikipedia's description of including files .

Answer 2

I followed this tutorial to get it set up:
