Linking to another project [SOLVED]

[Christian Flutcher]

My directory structure is like the following

Solution Directory
--Project1
--Project2

From Project2, I have to use classes written in Project1. I have included the header files like the below in Project2

#include "../Project1/SomeHeader.h"

I can see the classes in intellisense but the problem occured with linker. It is saying about unresolved external symbols. I am looking for a method to link the file to Project1. Any thoughts? EDIT: I solved it by adding the project dependencies. Right click on the project -> Project dependencies -> Check the Project1, save and build. :) I'd like to hear from you guys that is this the right approach to solve the above described problem? Thanks

What kind of projects are Project1 and Project2 ? Is Project1 a library ? If yes, then your approach is the correct one (of course you need to add the library in the project settings of Project2).

Yes. Project1 is a library.

Did you mean the linker settings? If yes, I haven't done that but the build and linking was successful. Am I missing something?

That's a bit strange... Normally you should have added it in the project properties: "Linker" category" -> "Input" and you should add it in the "Additional Dependencies". EDIT: or another way to do it is to make use of a #pragma. That's what you did maybe ? In such case, you don't need to change the properties of project 2.
