You are ready to rock and roll! How to Add an External C++ Library to Your Project Using the Visual Studio IDEThis document is for compiling projects using C. You can use this code to test that everything is setup properly. your source code file…could also be main.cpp) and add the preprocessor directives at the top of the source file. Dynamic Libraries are – XYZ.dll for Windows, Unix/Linux/Mac – libXYZ.so.Static Libraries are – XYZ.lib for Windows, UNIX/Linux/Max – libXYZ.a.The path above needs to be the location where the linker can find the libraries (usually suffixed with. Step 8: Click Linker and add the Libraries Search Path the folder that contains the folder named ‘Eigen’…C:\XYZ\eigen-eigen-21301928\ Step 7: Click the Compiler tab and add the Include Paths:Į.g. Step 6: Right click on project name and click on Settings Step 3: Unzip the zip file to your computer. Step 2: Download the zip file that contains all the code. Step 1: Go to the website of the library.įor example, for the linear algebra library, Eigen, you go to this page: Eigen Main Page How to Add an External C++ Library to Your Project Using the CodeLite IDE Add the path for the actual code (i.e.Note that this process will be different if you are using another IDE for C++, but the two basic steps are the same for all IDEs: Without further ado, here is the step-by-step process for adding an external C++ library to your project using the CodeLite IDE and Visual Studio IDE. I found the library named “ Eigen.” I added the library to my project in the CodeLite IDE, and I was ready to go. Instead of writing the code from scratch, I searched the web for a linear algebra library in C++ that contained functionality for multiplying matrices. You can think of libraries as a plugin or add-on that gives you more functionality.įor example, I wanted to write a program that is able to multiply two matrices together. They prevent you from having to reinvent the wheel when you need to implement some desired functionality. Libraries in C++ are collections of code that someone else wrote.
