CentOS

There are errors when I install gcc 4.8.5 on my machine. Can you help me figure out the problem?

CPU: AMD 5950X (Ryzen 9)
Centos version: CentOS Linux release 8.3.2011
The default gcc version: gcc (GCC) 8.3.1 20191121 (Red Hat 8.3.1-5)

Below is what I did
$ dnf install -y gcc texinfo-tex flex zip libgcc.i686 glibc-devel.i686
It shows "Error: Unable to find a match: texinfo-tex"

Then, I dowloaded gcc 4.8.5 files
$ wget ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.5/gcc-4.8.5.tar.gz
$tar zxf gcc-4.8.5.tar.gz
$cd gcc-4.8.5
$./contrib/download_prerequisites

$mkdir gcc-build-4.8.5
$cd gcc-build-4.8.5
$../configure --prefix=/usr
$make
Then many "warning" information occur and the final lines are below

-----------------Error Message -----

Why do you try to do that?

If you want gcc 4.8.5 then use CentOS 7 where it is the default compiler. It doesn't exist on CentOS 8.

Thanks for you answer.
I bought AMD 5950X cpu and install CENTOS 7 was failed and install CENTOS 8 succeeded. But the software I would like to use seems to denpend on the version of gcc.
Do you know a way to install CENTOS 7 on AMD 5950X cpu?

I'm skeptic about such claims.

There are virtualization and containers, if one really has to.

You could run 7 in a VM on 8.
