In this tutorial we learn how to install libcgal12 on Debian 9. libcgal12 is C++ library for computational geometry

Introduction

In this tutorial we learn how to install libcgal12 on Debian 9.

What is libcgal12

libcgal12 is:

CGAL (Computational Geometry Algorithms Library) makes the most important of the solutions and methods developed in computational geometry available to users in industry and academia in a C++ library. The goal is to provide easy access to useful, reliable geometric algorithms.

The CGAL library contains:

  • the Kernel with geometric primitives such as points, vectors, lines, predicates for testing things such as relative positions of points, and operations such as intersections and distance calculation.
  • the Basic Library which is a collection of standard data structures and geometric algorithms, such as convex hull in 2D/3D, (Delaunay) triangulation in 2D/3D, planar map, polyhedron, smallest enclosing circle, and multidimensional query structures.
  • the Support Library which offers interfaces to other packages, e.g., for visualisation, and I/O, and other support facilities.

This package contains the main library libCGAL.so as well as two support libraries libCGAL_Core.so (from the CORE project) and libCGAL_ImageIO.so (image I/O). The library libCGAL_Qt5.so used for visualization in demos can be found in the package libcgal-qt5-12.

There are three methods to install libcgal12 on Debian 9. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.

sudo apt-get update

After updating apt database, We can install libcgal12 using apt-get by running the following command:

sudo apt-get -y install libcgal12

Install libcgal12 Using apt

Update apt database with apt using the following command.

sudo apt update

After updating apt database, We can install libcgal12 using apt by running the following command:

sudo apt -y install libcgal12

Install libcgal12 Using aptitude

If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Debian. Update apt database with aptitude using the following command.

sudo aptitude update

After updating apt database, We can install libcgal12 using aptitude by running the following command:

sudo aptitude -y install libcgal12
