How to Install devtoolset 8 in RHEL 8 image - rhel8

Please help me to install dev toolset-8 in rhel 8 image.
i have pulled the base image as below . I want to install devtoolset-8. is there any other way please let me know.
sudo docker pull

According to that article, you can check if you have access to Red Hat Software Collections (RHSCL) by running the following command by the root user:
$ su -
# subscription-manager repos --list | egrep rhscl
If you have, enable necessary software repo and then install devtoolset:
# subscription-manager repos --enable rhel-7-server-optional-rpms
# yum install devtoolset-8

The other answer seems to be for RHEL 7.
On the RedHat site
Chrisian Labisch answered this with:
RHEL 8 doesn't work with Software Collections, RHEL 8 uses modules instead.
sudo dnf module list
In RHEL 8 you find the developer tools in the CodeReady Builder repository. :)
sudo subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
But even that seems to be unneeded because the system compiler version for RHEL is already GCC 8, so you would normally only need devtoolset-9 or up for it, if I understood the purpose correctly.
Additionally this blog post outlines the differences between the old SCL toolsets and the new AppStreams concept.

devtoolset is called gcc-toolset in RHEL8.
The following commands worked for me:
microdnf install -y gcc-toolset-12
scl enable gcc-toolset-12 bash
gcc --version
# gcc (GCC) 12.1.1 20220628 (Red Hat 12.1.1-3)


Trying to install epel-release on Fedora 30 -- no match for argument: epel-release

I'm on Fedora 30. I am trying to install "epel-release".
I am following this guide: -- I am unable to successfully run the command:
$ sudo yum install -y epel-release yum-utils
I get as a result:
No match for argument: epel-release
So, I tried the following commands from this article:
$ cd /tmp
$ wget
$ yum install ./epel-release-latest-*.noarch.rpm
No such luck - this is the output:
Problem: problem with installed package fedora-release-workstation-30-1.noarch
- package epel-release-7-11.noarch conflicts with fedora-release provided by fedora-release-workstation-30-1.noarch
- package epel-release-7-11.noarch conflicts with fedora-release provided by fedora-release-workstation-30-4.noarch
- conflicting requests
I have also tried:
$ sudo dnf install epel-relase
which that didn't work either, here's the results:
No match for argument: epel-release
Error: Unable to find a match
I have come across several different articles basically saying to either use the first command listed or variations of the second command I've tried - all unsuccessful. side note: Is this because Fedora 30 was just "recently" released?
My end goal is to deploy a Ruby on Rails web app internally using Nginx. For that, I am following this guide:
Any direction for how to install epel-release would be great as I can't move forward until passenger is installed.
Note that EPEL is not suitable for use in Fedora! Fedora is not Enterprise Linux. EPEL provides "a high quality set of additional packages for Enterprise Linux, including, but not limited to, Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux (SL), Oracle Linux (OL)". Put simply, Enterprise Linux is a term that refers to Red Hat Enterprise Linux or one of its clones. And Fedora is not a Red Hat clone.
That is why you cannot install the "epel-release" package in Fedora. It simply does not exist. Don't try to use EPEL on Fedora.
As noted before, the Fedora repositories provide most (if not all) of the EPEL packages. Additional software for Fedora is available in the RPMFusion repositories. In their own words, RPMFusion is "an extension of Fedora" that "provides software that the Fedora Project or Red Hat doesn't want to ship." RPMFusion can not be used on Enterprise Linux. You could see RPMFusion as the "EPEL alternative" for Fedora, but be aware that the software collections provided by RPMFusion and EPEL are entirely unrelated and uncomparable.
EPEL is managed from within the Fedora project, and thus part of Red Hat. RPMFusion is an independent organization. You can consider their repositories reliable, but always be cautious when you install software from external sources.
Finally - on a sidenote - on recent Fedora versions, 'dnf' has replaced 'yum'.
Okay, so turns out that this can be simplified to just:
$ sudo dnf install passenger
Crazy that they have an entire tutorial for how to install passenger when it can just be simplified to this one line.
you'll need to install the EPEL (Extra Packages for Enterprise Linux) repository.
The EPEL project is run by the Fedora team.
When you install third-party repositories on Red Hat and CentOS systems.
Install in centos:
sudo yum install yum-plugin-priorities epel-release
When the installation completes, navigate to the /etc/yum.repos.d directory,
and open the CentOS-Base.repo file in your favorite text editor.
After the last line of the base, updates, and extras sections, add the line: priority=1.
After the last line of the centosplus section, add the line:
Save the file and close the editor.
Now, Open the epel.repo file for editing.
After the last line of the epel section,add the line:
After the last line of each remaining section, add the line:
Update the system and then create a list of the installed and available packages by running:
sudo yum upgrade
sudo yum list > yum_list.txt
For RHEL - dnf install
Try with the above command to install epel-release in RHEL 8

How to install GCC/G++ 8 on CentOS

I'm used to install packages on Debian/Ubuntu distributions, but now I need to install gcc and g++ version 8.*. There is only version 4.* in CentOS repositories. What's the correct way to install them manually?
CentOS 8 already comes with GCC 8.
On CentOS 7, you can install GCC 8 from Developer Toolset. First you need to enable the Software Collections repository:
yum install centos-release-scl
Then you can install GCC 8 and its C++ compiler:
yum install devtoolset-8-gcc devtoolset-8-gcc-c++
To switch to a shell which defaults gcc and g++ to this GCC version, use:
scl enable devtoolset-8 -- bash
You need to wrap all commands under the scl call, so that the process environment changes performed by this command affect all subshells. For example, you could use the scl command to invoke a shell script that performs the required actions.
Permanently adding DTS to your development environment
After installing the devtoolset:
yum install devtoolset-8-gcc devtoolset-8-gcc-c++
You can also use the following command, to make DTS the default:
source scl_source enable devtoolset-8
The benefit of this command is that it can be added to .bashrc, so that you don't have to run the scl command every time you login:
scl enable devtoolset-8 -- bash
CentOS 8, to install dev tools: sudo dnf groupinstall "Development Tools"

Install make 3.75 on ubuntu 15.10

I am new to ubuntu. I am looking for any help in installing GNU Make version 3.75 or other older version on ubuntu 15.10. I understand that the package for older version doesnot exist for ubuntu 15.10 and I am not able to get the instruction anywhere on how to get the packages.
Any help regarding this is appreciated.TIA
sudo apt-get build-dep make
tar xvf make-3.75.tar.gz
cd make-3.75
sudo make install prefix=/opt/make-3.75
# or sudo make install to install it into /usr/local
Why do you need this? As arved suggests: if your Makefiles are 20 years old and incompatible with current versions of make, and can't be fixed, you probably have bigger problems elsewhere. Whatever those Makefiles try to do may require some tweaking to work on Ubuntu 15.10.

Python 3.3 Install - Freeze - Linux 3.4 Amazon ec2

I am very new to server setup and have spun up an Amazon stock ec2 server with Linux 3.4 on it.
I am trying to get python 3.3 onto it. I have so far installed the following:
yum install gcc gcc-c++ autoconf automake
When I try and run:
./configure --prefix=/opt/python3.3
the output I get freezes on "checking whether gcc accepts -pthread... "
Can you please let me know where to start looking to solve this problem? I'm using a combination of a few tutorials, but primarily ? Unfortunately, this tutorial is for Ubuntu and my server is CentOs. I therefore, use yum instead of apt-get.
Thank you for your help or guidance.

Install gcc-c++ on CentOS without yum

Can I install gcc++ on CentOS 6.x without `yum install gcc-c++ ....' ?
Is there any .tar or .rpm package available for download?
Yum will install rpm from it's repository.
So I don't understand why you want to avoid yum, it will solve dependencies and install them as well.
However, here is official RPM repository mirror (one of many):
Here is list of all mirrors :
You will need at least 3 RPMs:
For compilation of C/C++ you will also need libstdc++, glibc, etc
When you run
yum install gcc
Everything is done
As you did not specified architecture I assume i386, but URL is very similar for x86_64:
If you want to install it as a local user (or as a superuser)
GNU GSRC provides an easy way to do so
After installation via bzr, simply do these:
./configure --prefix=~/local
make -C gnu/gcc
(or make -C gnu/gcc MAKE_ARGS_PARALLEL="-jN" to speed up for a N-core system)
make -C gnu/gcc install
