Linaro Toolchain

The latest Arm release of the pre-built GNU cross-toolchain for Cortex-A GCC 8.3-2019.03 is now available on the Arm Developer website.

Linaro provides monthly GCC source archive snapshots of the current Linaro GCC release branch, as well as quarterly releases of pre-built Linaro GNU cross-toolchain binary archives.

The following tables provide direct access to the most common Linux and bare-metal ABI variants of the Linaro binary cross-toolchain quarterly releases. Both x86_64 Linux and Mingw32 (MS Windows compatible) host binaries are provided:

Interested in other target ABIs such as big-endian or soft-float little-endian? All toolchain target ABI and host variants can be seen here. Note: Not all ABI and host variants are supported to the same degree. See the release-notes for more information.

Interested in Cortex-R and Cortex-M bare-metal targeted toolchains for Arm embedded processors? We’re working with Arm to also supply a new release every year (with quarterly updates). Releases are maintained for two years. Get these directly from the Arm website

Linaro code exists in many states and is found in many places. Working upstream means that the ultimate goal for most code is to be accepted and incorporated into something like the Linux kernel or GCC tool chain. The Patches website presents this work by team and by upstream project.

Before the code gets accepted upstream, Linaro maintains various development repositories and Linaro’s groups make regular releases of various builds including Android, the LAVA test framework, key toolchains and builds for specific member products.

This page provides links to many of the more popular downloads produced by Linaro’s engineering teams.

Linaro Member Builds

LMBs are full system builds of popular open-source products set up at the request of a Linaro Core/Club Member company.

Snapshots code shows Linaro work in progress. Often created on a daily basis, these are literally snapshots of work in progress that are used for testing and development. The code on this site may not work and should only be used by experienced engineers who know exactly what they are doing.

The Linaro Automated Validation Architecture (LAVA) is a test and continuous integration framework that Linaro uses to validate its releases. The source is open so that members and others can create their own instantiations and run proprietary tests within this standard framework. Click here for the latest downloads.

Security Downloads

Linaro security downloads are available from several of Linaro’s engineering groups. The most recent work includes collaboration on Meltdown/Spectre fixes backported in to the 4.4, 4.9 and 4.14 kernels.

LKFT is Linaro’s Linux Kernel Functional Test framework. The mission of LKFT is to perform functional regression testing on select Linux kernel branches in real time (as they’re updated) and report any regressions as quickly as possible. This is performed by executing a variety of functional-tests on a selection of user-space operating systems.


Linaro Confectionary Release (LCR) is a reference build of the Android Open Source Project (AOSP) for supported development boards that blends board support, latest kernels, AOSP and other Linaro technologies like OPTEE in one place. LCR is provided as is however we are interested in bug reports and will fix them on a best effort basis. Downloads can be found on both and
