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.

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.

  • Baremetal sysroot names now contain ‘newlib’ rather than ‘glibc’.
  • Manifests now contain relative paths rather than absolute paths.
  • Now generating proper manifest files.
  • Fixed pi requeue support in glibc 2.21 while allowing the existing 2.21 minimum kernel default setting. This was checked into the linaro/2.21/master branch.
