The Linaro Binary Toolchain ============================

The Linaro GCC 5.3-2016.05 Release is now available.

Notice: All Linaro GCC 5 series toolchain users should migrate to the latest version of the Linaro GCC 5 toolchain in order to mitigate potential security exposure to CVE-2015-7547. See the NEWS section below for details.

Host Requirements ==================

Linaro officially supports the current and previous Ubuntu LTS releases (as of the time of this release). This does not mean that the toolchain will not work on other/older Linux distributions. See the following for the life-time of Ubuntu LTS releases.

https://wiki.ubuntu.com/Releases

The host system upon which the cross-compiler will run requires a minimum of glibc 2.14, because of API changes to glibc's memcpy API.
