How can I get glibc 2.35 on Ubuntu 20.04?

Question

I'd like to update to a 2022 version of glibc, at least 2.35. This seems to be available on Ubuntu 22.04, but how can I get it on 20.04?

Answer 1

You can use following commands to bring in newer version of glibc in ubuntu 20.04, but note that as it is a system package, upgrading it may impact your system.

apt-get install gawk bison gcc make wget tar -y
wget -c https://ftp.gnu.org/gnu/glibc/glibc-2.35.tar.gz
tar -zxvf glibc-2.35.tar.gz && cd glibc-2.35
mkdir glibc-build && cd glibc-build
../configure --prefix=/opt/glibc
make
make install
