The Linaro Binary Toolchain

The Linaro GCC 4.9-2017.01 Release is now available.

Notice: All Linaro GCC 4.9 series toolchain users should migrate to the latest version of the Linaro GCC 4.9 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.

NEWS for GCC 4.9 (as of Linaro GCC 4.9-2017.01)

  • The soft-float targeted toolchains have switched to -mfloat-abi=soft from -mfloat-abi=softfp.

This makes arm-linux-gnueabi and armeb-linux-gnueabi toolchains use “soft” FP ABI instead of “softfp”.

Historically, TCWG’s toolchains provided both “soft” and “softfp” multilibs, but when switching from crosstool-ng to cbuildv2/abe (which support a single multilib) “softfp” multilib was choosen. Using “-mfloat-abi=soft” is a better choice for a gnueabi toolchain, since it doesn’t require cores to have a floating-point unit.

This change should not break compatibility for toolchain users since the ABI will stay the same. The compiler and glibc libraries will not refernce FP instructions.

  • Host binaries for x86_64 linux hosts now have symbols and debug information stripped in order to reduce the size of the toolchain binary archives. This reduces the archive size from 830M to 480M for aarch64-linux-gnu target with the gcc-4.9-branch.
  • Removed .la files from binary installation as these files break autotools builds.

  • The mingw toolchains are now archived using the rsync -L option in order to avoid problems with Windows extractors and symbolic links.

  • Copy the libwinpthread DLL into the bin directories so it gets into the tmp directory before tar is run.

  • Applied fix for CVE-2015-7547 – A stack-based buffer overflow in glibc’s getaddrinfo() was corrected in glibc 2.23 and backported into Linaro eglibc 2.19 (linaro_eglibc-2_19).
