Unable to install Ruby 3.1.4 via rbenv on AlmaLinux/CentOS 7

Question

I am trying to install Ruby 3.14 on an AlmaLinux distrubtion via rbenv. Seems the build and the compiler are not compatible.

Has anybody seen this issue before and possibly found a solution?

It is strictly speaking not an issue with 3.1.4 fails same way on 3.2.2.

Many thanks in advance for you time taken:) Eugen

Command

rbenv install 3.1.4

Solved through this question, many thanks!

• Why do I get error compiling Ruby 3.2 on CentOS 7?

With root permissions

yum install centos-release-scl-rh
yum install devtoolset-7-gcc-c++

As rbenv user

CC=/opt/rh/devtoolset-7/root/usr/bin/gcc rbenv install 3.1.4 -v
