How to Download and Install GCC 7 on Various Operating Systems

The GNU Compiler Collection (GCC) version 7 is a powerful tool for compiling source code and is used widely across different platforms. In this guide, we'll provide detailed steps on how to download and install GCC 7 on Linux, Windows, and macOS. Whether you're a developer working on a project or a user looking to compile your own software, read on to find out how to get started.

Installing GCC 7 on Linux

Linux distributions offer several methods to install GCC 7, including through package managers and building from source. Follow the steps outlined below to install GCC 7 on your Linux system.

Using Package Manager

Ubuntu/Debian

Installing GCC 7 on Ubuntu or Debian can be done using the apt-get package manager.

n bash sudo apt-get install gcc-7 g -7

Fedora

For Fedora users, dnf is the preferred package manager.

n bash sudo dnf install gcc-7 g -7

CentOS/RHEL

CentOS and RHEL users may need to enable Software Collections (SCL) to install the latest versions of GCC.

n bash sudo yum install centos-release-scl sudo yum install devtoolset-7-gcc devtoolset-7-g

Building from Source

If you need a specific version or prefer to build GCC 7 from source code, follow these steps:

Download the source code from the GNU FTP server. Extract the tarball: n bash tar -xvf gcc-7.5.0.tar.gz Install dependencies: n bash sudo apt-get install build-essential sudo apt-get build-dep gcc Configure and build: n bash cd gcc-7.5.0 ./configure --enable-languagescc --disable-multilib make -j$(nproc) sudo make install

After installation, verify that GCC 7 is correctly installed by running:

n bash gcc-7 --version

This command should display the GCC 7 version you just installed.

Installing GCC 7 on Windows

There are two primary methods to install GCC 7 on Windows: using MinGW-w64 and using Cygwin.

Using MinGW-w64

Download the MinGW-w64 installer from MinGW-w64. Choose the appropriate architecture (x86 or x86_64) and select GCC 7 in the options.

Using Cygwin

Install Cygwin from Cygwin website. During installation, search for and select GCC 7 in the package selection step.

If you prefer to build GCC 7 from source, you can follow similar steps as on Linux, but on a Windows machine.

Installing GCC 7 on macOS

If you have Homebrew installed, you can easily install GCC 7 by tapping the Homebrew versions repository and installing it.

n bash brew tap homebrew/versions brew install gcc7

For those who prefer to build from source, you can download the source code from the GNU FTP server and follow the build instructions.

At any point if you have GCC 5 installed and wish to use it to compile and install GCC 7 from source, it's possible but more complex, requiring handling of dependencies. Search for a binary of GCC 7 that matches your operating system can be a simpler solution.
