d여기에서 Upgrade gcc and g++ in Ubuntu – ubuntu gcc update 주제에 대한 세부정보를 참조하세요
A brief description of how to upgrade gcc and g++ from version 5.4.0 to version 6.2.0 in Ubuntu Linux. Please click the \”Show more\” (if the Update November 2019 is not displayed) text below for the updated commands for gcc-9 an g++-9.
November 2019:
After a question from Gery M:
To get gcc 9.x and g++ 9.x, just follow the steps described, replacing the version number with 9.
If you are starting from gcc 8.x or lower you may have to do a stepped upgrade. For example, to go from gcc-5 to gcc-6 (g++-5 to g++-6). Follow the steps outlined below and in the video, but replace the version number with the version immediately following the installed version:
(installed) gcc-5 g++-5 (upgrade to)
(installed) gcc-6 g++-6 (upgrade to)
(installed) gcc-7 g++-7 (upgrade to)
(installed) gcc-8 g++-8 (upgrade to)
gcc-9 g++-9
Keep a good eye on any error messages. If necessary, you will have to upgrade any seemingly unrelated files to a more current version. This will ensure your compiler upgrade works properly and you will, hopefully, not run into obscure and difficult, if not impossible, to fix errors in your application/library compilations.
Usual caveats apply
April 2019:
To get gcc-8 and g++-8, as before replace gcc-6 or gcc-7 with gcc-8 and g++-6 or g++-7 with g++8.
The command sequence will now be:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-8 g++-8
sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-8 20 –slave /usr/bin/g++ g++ /usr/bin/g++-8
Sept 2017
This works with upgrading gcc-6/g++-7 as well. If you are starting from a version of gcc that is lower than 6, it is probably better to to do incremental upgrades rather than a straight up upgrade.
Just replace the gcc-6 and g++-6 with gcc-7 and g++-7
Usual caveats apply.
List of Commands:
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-6 g++-6
sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-6 20 –slave /usr/bin/g++ g++ /usr/bin/g++-6
(corrected after comment from Belmokaddem Adil – thank you! 😀 )

Has something recently changed in the release philosophy of Ubuntu?
Install and make GNU GCC 10 default in Ubuntu 20.04 Focal
The best way to install and use GNU GCC 10 is to install first, build-essential package, which will pull in the GNU GCC 9.2, and then install the GNU GCC 10. In fact, it is possible to install only GNU GCC 10 packages, but build-essential brings with it many additional packages, which are mandatory for the configuration and compiling stages.
GNU GCC is included in the official Ubuntu Focal repository! It just needs to be installed and made to be the default compiler.
Install build-essential ensures all generic packages to be installed, which are involved in the building process of a software product.
There are three steps to install and use GNU GCC 10 under Ubuntu 20.04:
Install build-essential package. Install gcc-10 packages (g++, too). Make GNU GCC 10 default compiler – use update-alternatives to point the GNU GCC 10 as the default compiler
Four simple lines and the third is a little bit more complex:
apt update -y apt upgrade -y apt install -y build-essential apt install -y gcc-10 g++-10 cpp-10 update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-10 100 –slave /usr/bin/g++ g++ /usr/bin/g++-10 –slave /usr/bin/gcov gcov /usr/bin/gcov-10
Always update and upgrade before installing new software. Use sudo before each command, if installation is performed by a user other than root:
sudo apt update -y sudo apt upgrade -y sudo apt install -y build-essential sudo apt install -y gcc-10 g++-10 cpp-10 sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-10 100 –slave /usr/bin/g++ g++ /usr/bin/g++-10 –slave /usr/bin/gcov gcov /usr/bin/gcov-10
It is a good idea to install cmake package, in addition to the above, because cmake is not included in build-essential:
apt install -y cmake
The apt output of installing GNU GCC 10
Many additional packages like multiple perl modules, libraries and make are installed.

Step 2: Install GCC
Afterward, it is recommended to install the build-essential package that consists of packages of GCC and many other applications.
$ sudo apt install build-essential
Output
Step 3: Evaluate Installation
Now to verify the successful installation of GCC evaluate the C compiler version through the following command.
$ gcc –version
Output
Step 4: Create a C program
Once installed, verify if the compiler is working properly or not by creating a simple C program. For instance, below we have created a simple hello world C program in nano editor and saved the file as helloworld.c.
Save this file and convert this into an executable one.
$ gcc -o helloworld helloworld.c
This command will generate a binary file by the name “helloworld” in the same directory. Now you have to execute the program using the below-mentioned command.
$ . / helloworld
Output
The C program was executed successfully.
Voila! GCC has been successfully installed on Ubuntu 22.04.
Conclusion
For the purpose of installing GCC on Ubuntu 22.04, first update it by using the command $ sudo apt update then install the build-essential package that contains the GCC package through the command $ sudo apt install build-essential. Then use the $ gcc –version command to verify the successful installation of GCC. Lastly, make a simple C program and compile and execute this program using these commands; $ gcc -o filename filename.c, and $ ./filename.

Install GCC (build-essential) on Ubuntu 20.04 LTS
GCC, better known as The GNU Compiler Collection, is a set of compilers, development tools, and front ends such as C, C++, Objective-C, Fortran, Ada, Go, and D. GCC is open-source and is widely used as it was the original compiler for GNU and currently is in use to compile the Linux Kernel along with many other projects.
In the following tutorial, you will learn how to install GCC on Ubuntu 20.04 LTS Focal Fossa desktop or server.
Prerequisites
Recommended OS: Ubuntu 20.04.
Ubuntu 20.04. User account: A user account with sudo or root access.
The tutorial will utilize the terminal interface, which can be found in the show applications menu.
Example:
Update Operating System
Update your Ubuntu operating system to make sure all existing packages are up to date:
sudo apt update && sudo apt upgrade -y
The tutorial will be using the sudo command and assuming you have sudo status.
To verify sudo status on your account:
sudo whoami
Example output showing sudo status:
[joshua@ubuntu ~]$ sudo whoami rootTo set up an existing or new sudo account, visit our tutorial on How to Add a User to Sudoers on Ubuntu.
Use the following command with the root password to log in to use the root account.
su
Option 1 – Install GCC with APT – Ubuntu Repository
The first recommended option to install GCC is to install the build-essential package containing GCC and many other application packages such as make.
To begin the installation, use the following command.
sudo apt install build-essential
Example output:
Type Y, then press the ENTER KEY to proceed.
Once installed, verify the installation and check the version using the following command.
gcc –version
Example output:
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0
Option 2 – Install Latest GCC with APT – Toolchain PPA
The second option is to install the Toolchain PPA, which contains the latest versions of GCC.
To import the PPA, use the following command.
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y
For users that have installed the build-essential package, you can run an update and upgrade.
sudo apt update && sudo apt upgrade
For users who need to install for the first time, run the same command as option 1.
sudo apt install build-essential
Install & Configure Multiple Versions
For developers and specific users, you may require multiple versions installed of GCC.
First, install the versions you require, or install four versions of GCC along with G++.
Example:
sudo apt install gcc-8 g++-8 gcc-9 g++-9 gcc-10 g++-10 gcc-11 g++-11
Once installed, you can use the update-alternatives command to configure the priority of each version. The default version used on your system will be the highest priority.
Below is an example of setting all 4 with a priority split, with GCC-11 being the highest set at priority 100.
sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-11 100 –slave /usr/bin/g++ g++ /usr/bin/g++-11 –slave /usr/bin/gcov gcov /usr/bin/gcov-11 sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-10 80 –slave /usr/bin/g++ g++ /usr/bin/g++-10 –slave /usr/bin/gcov gcov /usr/bin/gcov-10 sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-9 60 –slave /usr/bin/g++ g++ /usr/bin/g++-9 –slave /usr/bin/gcov gcov /usr/bin/gcov-9 sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-8 40 –slave /usr/bin/g++ g++ /usr/bin/g++-8 –slave /usr/bin/gcov gcov /usr/bin/gcov-8
Confirm GCC-11 is now the default version of your system.
gcc –version
Example output:
gcc (Ubuntu 11.1.0-1ubuntu1~20.04) 11.1.0
The default GCC version set on your system can be re-configured. Use the following command first to list the priority.
sudo update-alternatives –config gcc
Example output:
As above, you need to enter the number of the version corresponding to the list you would like to switch to.
For example, switching from GCC-11 to GCC-10, just type 2 and press the ENTER KEY.
Confirm the version switch has occurred successfully using the –version command.
gcc –version
Example output:
gcc (Ubuntu 10.3.0-1ubuntu1~20.04) 10.3.0
Compile a Hello World Example
Test compiling with GCC, create the famous “Hello World” in a C program using any text editor, the tutorial will use nano.
nano hello.c
Next, add the following.
#include
int main() { printf(“Hello, World from Linuxcapable.com!”); return 0; } Save the file, CTRL+O, then exit CTRL+X.
Compile the Hello World test using the following command.
gcc hello.c -o hello
Next, run the hello compiled program.
./hello
Example output:
Hello, World from Linuxcapable.com!
A handy package to install is the manual pages (man page). This will help you with using GNU by providing documentation on your system.
Use the following command to install the manpages-dev package. By default, this should be installed on most Ubuntu systems.
sudo apt-get install manpages-dev
Once installed, use the following command to bring up the options.
man -h
In the tutorial, you have learned how to install GCC, along with a PPA option for newer GCC alternatives and how to switch between versions on Ubuntu 20.04 LTS Focal Fossa.
