Linuxbrew uses Ubuntu 16.04 LTS (Xenial Xerus) with glibc 2.23 and GCC 5.4.0 on CircleCI to build precompiled binary bottles. The minimum Linux kernel version required by glibc 2.23 is 2.6.32. The minimum GCC version required to build glibc is 4.7. We plan for the bottling architecture to follow the Ubuntu long term support releases.

Portable bottles

Formulae that are dependencies of glibc, namely binutils and patchelf, are built on the oldest supported distribution of Linux, currently CentOS 6 and Ubuntu 11.04 LTS (Lucid Lynx). See Build a portable bottle.
