Introduction to CGAL and Conan.io

CGAL (Computational Geometry Algorithms Library) is a popular open-source library that provides efficient and reliable geometric algorithms. Conan.io, on the other hand, is a package manager for C++ that simplifies the installation and management of dependencies. In this article, we will demonstrate the seamless integration of CGAL with Conan.io, ensuring a hassle-free installation experience.

Prerequisites

Before proceeding with the installation, make sure you have the following prerequisites in place:

  • Conan.io installed on your system (if not, follow the installation instructions on the Conan.io website)
  • A C++ compiler compatible with CGAL (e.g., GCC, Clang, or Visual Studio)

Installing CGAL using Conan.io

To install CGAL using Conan.io, follow these straightforward steps:

  1. Open a terminal or command prompt and navigate to your project directory.

  2. Run the following command to create a new Conan.io project:

    conan new my_cgal_project

  3. Add the CGAL requirement to your project’s conanfile.txt file:

    [requires]\ncgal/5.0.2

  4. Install CGAL using Conan.io:

    conan install .

  5. Verify the installation by checking the CGAL version:

    conan search cgal

Using CGAL in Your Project

Now that CGAL is successfully installed using Conan.io, you can start using it in your C++ project:

Include the necessary CGAL header files in your project:

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>

Use CGAL algorithms in your code, such as:

typedef Kernel::Point_2 Point_2;
Kernel kernel;
Point_2 p = Point_2(1, 2);

Conclusion

In this article, we have demonstrated the seamless integration of CGAL with Conan.io, providing a hassle-free installation experience. By following these simple steps, you can now effortlessly utilize CGAL’s powerful geometric algorithms in your C++ projects, leveraging the convenience of Conan.io’s package management.

Frequently Asked Question

Get ready to conquer the world of geometric algorithms with CGAL! But first, let’s get it installed using conan.io. Here are the answers to your burning questions:

What is conan.io and why do I need it to install CGAL?

Conan.io is a package manager for C/C++ libraries and binaries. It helps you to easily install, manage, and integrate CGAL into your project. Think of it as a superhero sidekick that saves you from the evils of manual installation and dependency hell!
