GCC 10.1.0 on Ubuntu 16.04 & 18.04 & 20.04:

sudo apt-get update -y && 
sudo apt-get upgrade -y && 
sudo apt-get dist-upgrade -y && 
sudo apt-get install build-essential software-properties-common -y && 
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y && 
sudo apt-get update -y && 
sudo apt-get install gcc-10 g++-10 -y && 
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 60 --slave /usr/bin/g++ g++ /usr/bin/g++-10 && 
sudo update-alternatives --config gcc

select gcc-10

To ivanmara555's comment using the ppa repository...

As of today May 25th 2020 on Ubuntu 20.04 your list of commands does not install the latest 10.1.0. Instead, it installs the older "10.0.1 20200416 (experimental) (Ubuntu 10-20200416-0ubuntu1)" -- because the older version is the only one there at that PPA site for release "Focal". The other package "10.1.0-2ubuntu1~18.04" is for "Bionic" not "Focal".

On 20.04, run the following commands today (May 25th, 2020) and it shows that none of the packages are 10.1:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt list -a gcc-10

If you can't find a PPA with "10.1.0", you'll have to build it from source. As a side note, the daily build of the next Ubuntu 20.10 does install 10.1.0.

Yes, gcc-10 is not available on xenial, even in the toolchain repo (see the filter dropdown):

Thank you very much!

gcc-9[-multilib] and g++-9[-multilib] are also available for Ubuntu 12.04 LTS!

I extended the steps above, as they complain with g++ can't be slave of gcc + some additions and beautifications:

#!/bin/bash

GCC_GXX_VERSION=9
gcc_alternatives=(gcc cc)
gxx_alternatives=(g++ c++ cpp)
all_alternatives=("${gcc_alternatives[@]}" "${gxx_alternatives[@]}")

remove_alternatives() {
    alternatives=("$@")
    for alt in "${alternatives[@]}"; do
        sudo update-alternatives --remove-all $alt || continue
    done
}

install_and_set_alternatives() {
    path=$1
    shift
    alternatives=("$@")
    for alt in "${alternatives[@]}"; do
        sudo update-alternatives --install /usr/bin/$alt $alt $path 100
        sudo update-alternatives --set $alt $path
    done
}

print_green() {
    args=$@
    echo -e "\033[0;32m$args\033[0m"
}

check_versions() {
    alternatives=("$@")
    for alt in "${alternatives[@]}"; do
        print_green "$alt\t->\t`$alt --version | head -n 1`"
    done
}

Hi All,
I am trying to install GCC12 on ubuntu 20.04.6 LTS (Focal Fossa) os but not able to find GCC12. tried to use the above command but with gcc-12.
can anybody provide any suggestions?

I actually just tried this and it appears that gcc12 and 13 are only available as a package on Ubuntu 22.04 and later. If you want it on earlier versions you'll have to build it from source. 😭

sinugowde · 2023-05-16T11:01:48Z

Thanks @jasonbeach for your inputs..

Pomax · 2024-10-25T00:10:40Z

this still doesn't explain how to install gcc/g++10 on ubuntu 16.04.7, which some folks are still not by choice forced to work with.

alexandreelise · 2024-10-25T00:28:55Z

@Pomax. Your account seems to behave like a bot. Since I unsure. I'll ignore your comments from now on. If you are not a bot. The real answer to what you want is trial and error until you succeed. Struggles is part of the journey. Instant answer on a plate will not help you learn. Have a delightful day (bot)?

jasonbeach · 2024-10-25T00:37:22Z

Heh...apparently the bot doesn't get the sadistic humor of still being forced to work on an O.S. that stopped being supported 3yrs ago.

Regardless, it appears there is no prebuilt package for gcc10 on 16.04 which means if you want it you'll have to build it from source. Clang is surprisingly easy to build from source but I have no idea about GCC.

Pomax · 2024-10-25T03:44:03Z

@alexandreelise weird thing to say based on two comments on related gist from someone with multiple 1500+ star repos, but okay? I found this gist while looking for info on how to install the latest GCC on Ubuntu 16, so past version 9, which is what the other gist I commented on was for. Of course, I had been hoping someone had posted a copy-paste solution for gcc 10 already, but that was unfortunately not the case. I might add a comment with instructions if I can make some of the stackoverflow posts I managed to find work.

As for @jasonbeach's sadism remark, that's unfortunately far too real: I'm forced to work on a project that's still stuck on Ubuntu 16.04.7 (and not even kernel 4.15, but 4.4). I wish it wasn't, reality is not always so kind. There are way too many projects still stuck on 8 year old code bases running on even older infrastructure. I'm just trying to find anything that will let me get these projects migrated off of these dead versions of ubuntu.

	These commands are based on a askubuntu answer http://askubuntu.com/a/581497
	To install gcc-6 (gcc-6.1.1), I had to do more stuff as shown below.
	USE THOSE COMMANDS AT YOUR OWN RISK. I SHALL NOT BE RESPONSIBLE FOR ANYTHING.
	ABSOLUTELY NO WARRANTY.

	If you are still reading let's carry on with the code.

	sudo apt-get update && \
	sudo apt-get install build-essential software-properties-common -y && \
	sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y && \
	sudo apt-get update && \
	sudo apt-get install gcc-snapshot -y && \
	sudo apt-get update && \
	sudo apt-get install gcc-6 g++-6 -y && \
	sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-6 60 --slave /usr/bin/g++ g++ /usr/bin/g++-6 && \
	sudo apt-get install gcc-4.8 g++-4.8 -y && \
	sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.8;

	When completed, you must change to the gcc you want to work with by default. Type in your terminal:
	sudo update-alternatives --config gcc

	To verify if it worked. Just type in your terminal
	gcc -v

	If everything went fine you should see gcc 6.1.1 by the time I am writing this gist

	Happy coding!

	See my blog post at https://www.application2000.com
