- libc6-dev – C standard library.
- gcc – C compiler.
- g++ – C++ compiler.
- make – GNU make utility to maintain groups of programs.
- dpkg-dev – Debian package development tools.
Basically, build-essential package contains an informational list of packages which are considered essential for building Ubuntu packages including gcc compiler, make and other required tools. This package also depends on the packages on that list, to make it easy to have the build-essential packages installed. In this tutorial, you will learn about installing the GNU C compiler and GNU C++ compiler on a Ubuntu Linux.
Installing compilers using apt command
Open the terminal app and type the following apt command/apt-get command:
OR
Sample outputs:
$ sudo apt update
$ sudo apt upgrade
$ sudo apt install build-essential
OR
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install build-essential
Sample outputs:
Verify installation
Type the following commands:
$ whereis gcc make
$ gcc --version
$ make -v
Installing the dev man pages on a Ubuntu Linux
Type the following command:
To view library calls (functions within program libraries), enter:
You can write a small program to test GNU c/c++ compiler:
Append the following code:
$ sudo apt-get install manpages-dev man-db manpages-posix-dev
To view library calls (functions within program libraries), enter:
$ man 3 scanf
$ man 2 execve
$ man 2 fork
You can write a small program to test GNU c/c++ compiler:
$ vi test.cpp
Append the following code:
Save and close the program. You can compile it as follows:
OR
You should get an executable named test in the current directory:
Sample outputs:
$ make test
OR
$ g++ test.cpp -o test
You should get an executable named test in the current directory:
$ ls -l test
Sample outputs:
Just run it:
$ ./test
Installing the X11 development compilers
Type the following command:

Introduction
This guide explains how to install OR-Tools from source, with support for C++, on Linux. Unless you plan to modify the source code or use a third-party solver with OR-Tools, we recommend the binary installation.
Although these instructions might also work on other Linux variants, we have only tested them on machines meeting the following requirements:
- Ubuntu 19.10/18.04/16.04 64-bit (x86_64)
- Debian 10.2 (buster) 64-bit (x86_64)
- Centos 8 64-bit (x86_64)

Prerequisites
The following sections describe the prerequisites for installing OR-Tools from source.
C++ tools
To install C++ tools, open a terminal window and enter:
Centos 8
Debian 10
Ubuntu 19.10
Ubuntu 18.04
Ubuntu 16.04
Download the source code
There are two distinct branches of the OR-Tools source code onGitHub: stable and master.The stable branch has been thoroughly tested and should work flawlessly on allsupported platforms. The master branch is where the latest updates and improvementshave been applied; it's more current, but less stable.
Download the stable source code
You can get the stable source code for OR-Tools in either of the following ways:
- Clone the stable branch by entering
- Download the latest release in a compressed file, byclicking the Clone or download buttonin GitHub.
Download the master source code
Install Dev C++ Ubuntu
To retrieve the source code from the master branch, enter
Download previous releases
You can get the source code for previous releases in either of the following ways:
- Download a previous release from the GitHub release page.
- Assuming you have already created a local repository (by
git clone
), you can check out a specific release using a Git tag. For example, to work with the v7.5 release instead of the master branch, enter the following commands in your local repo:
Linux Dev Block
Build the source code
To build the source code:
- Open a terminal and navigate to the directory where you extracted the files. Then enter the following command:
- To use a third party solver, open
Makefile.local
in the mainor-tools
directory, and add the path to the directory where you installed the solver. For example, for SCIP you would add this: - Compile OR-Tools by entering
- You can check that everything is running correctly by entering
This runs a selection of examples for OR-Tools. If all the examples run successfully, you are ready to get started with OR-Tools.
Using a third-party solver
You can use OR-Tools with any of the following third-party solvers:
If you have already installed OR-Tools and want to configure it to use one of these solvers,do the following steps:
- Open a terminal and navigate to the
or-tools
directory. Then enter the following command: - Open
Makefile.local
and add the path to the directory where you installed the solver. For example, for SCIP you would add this: - Compile OR-Tools by entering
![Dev Dev](/uploads/1/2/6/1/126157510/958258142.jpg)
Install the SCIP Optimization Suite
To install the SCIP Optimization Suite on Linux,do the following steps:
- Download the SCIP archive and unpack it.
- Navigate to the top level of the unpacked archive and enter the following commands:
After the installation is complete, follow the instructions inUsing a third-party solver.
Cleaning the build files
If you need to re-install OR-Tools, the command:
will remove all compiled dependencies and
Makefile.local
. This can be useful for resetting to a clean state.Then re-enter the commands
Install Dev C++ Software
Installing OR-Tools on your operating system
Install Dev C++ Linux Terminal 3
You can install OR-Tools for C++ on your operating system by entering
