如何在同一个项目中引用另一个VC ++项目？ [英] How do I reference one VC++ project from another in the same project?

问题描述

我是Visual Studio的新用户。需要您的帮助。

I am new to Visual Studio. Need your help with the following.

Visual Studio 2005，VC ++

1解决方案有2个项目。

调用解决方案作为'解决方案'

项目1被命名为p1，项目2被称为'p2'

我需要导出函数和类从'p1'所以我可以通过导入在'p2'使用它们？

如果我只是包括头文件，然后使用函数，直接调用它们呢？

Visual Studio 2005, VC++
1 solution has 2 projects.
Lets call the solution as 'solution'
Project 1 is named 'p1' and project 2 is called 'p2'
Do I need to export functions and classes from 'p1' so that I can use them by importing in 'p2'?
What if I simply include the header files and then use the functions by calling them straight away?

感谢，

Thanks, viren

推荐答案

正确地（一段时间没有使用C ++），有两种不同类型的C ++库 - 一个静态库（.lib文件）和一个动态库（一个.dll文件）。

If I remember correctly (haven't used C++ for a while), there were two different kinds of C++ libraries - a static library (a .lib file) and a dynamic library (a .dll file).

在静态库的情况下，你必须配置p2，使其链接到p1.lib（在项目属性中）;将p1添加到p2的依赖项，以便始终首先构建;然后根据需要包括p1的.h文件。

In the case of a static library you had to configure p2 so that it links to p1.lib (in project properties); add p1 to dependancies of p2, so that it is always built first; and then include the .h files from p1 as necessary.

.dll文件有点棘手 - .h文件必须有 __declspec（dllimport）和 __ declspec（dllexport）我想。还有一些魔法。不确定真的。

The .dll file was a bit more tricky - the .h files had to have __declspec(dllimport) and __declspec(dllexport) I think. And there was some more magic. Not sure really. But these are the keywords that might get you up and running.

请注意，这是一个MS特定的关键字，不适用于其他编译器。

Note that this is a MS specific keyword and will not work on other compilers.
