ldd --version shows that I have Ubuntu GLIBC 2.27-3ubuntu1, and I need a version <= 2.24. Tried to use sudo apt-get install libc6==2.23-0ubuntu1 but it says this version cannot be found. I have searched on Ubuntu packages to find a version that suits my requirements but couldn't find anything.

Can anyone help to downgrade my libc6? I need my gcc to compile with GLIBC <= 2.24 for a plugin I'm making.

Why do you think an old version of glibc is required for building a GCC plugin? – Florian Weimer Feb 09 '19 at 18:07
@FlorianWeimer because of `version GLIBC_2.14 not found` error – Marvin Effing Feb 11 '19 at 10:18
But glibc 2.27 from Ubuntu has version GLIBC_2.14. Are you building on Ubuntu and deploying on something else (including an older version of Ubuntu)? – Florian Weimer Feb 11 '19 at 10:21
The latter. Client had a lower version of GLIBC so that I needed to downgrade. I ended up just using an ancient version of openSUSE to compile – Marvin Effing Feb 11 '19 at 10:25
