Toolchain Releases

v1.4.2

This release reverts the switch from 4.14 headers to 4.4 headers in v1.4.0. This re-enables libgpiod (cdev), bluez5, iwd, and ply (eBPF) which required headers after 4.4.

  • Fixes

    • ARMv7 toolchain now defaults to "generic-arm-v7a" rather than "cortex-a9". This fixes a potential issue of generating invalid ARM instructions, but it appears that this did not affect ARM Cortex-A7 and A8 platforms supported by Nerves.

  • Tool versions

    • GCC 10.2
    • Linux 4.14 headers
    • glibc 2.33
    • binutils 2.36.1

v1.4.1

This release adds host support for native Mac M1 toolchains.

Hardware float has been enabled on the armv6 toolchain to further consistency with https://toolchains.bootlin.com configurations.

  • Updated dependencies
    • nerves_toolchain_ctng v1.8.2

v1.4.0

This release updates gcc from version 9.2.0 to 10.2.0 and includes various updates to the C runtime. See https://gcc.gnu.org/ for the many changes in the gcc 10.x releases.

All toolchains have been renamed to set the vendor to nerves. ARM32 toolchains were renamed for consistency with https://toolchains.bootlin.com naming.

nerves_toolchain_aarch64_unknown_linux_gnu        -> nerves_toolchain_aarch64_nerves_linux_gnu
nerves_toolchain_armv5tejl_unknown_linux_musleabi -> nerves_toolchain_armv5_nerves_linux_musleabi
nerves_toolchain_armv6_rpi_linux_gnueabi          -> nerves_toolchain_armv6_nerves_linux_gnueabi
nerves_toolchain_arm_unknown_linux_gnueabihf      -> nerves_toolchain_armv7_nerves_linux_gnueabihf
nerves_toolchain_i586_unknown_linux_gnu           -> nerves_toolchain_i586_nerves_linux_gnu
nerves_toolchain_mipsel_unknown_linux_musl        -> nerves_toolchain_mipsel_nerves_linux_musl
nerves_toolchain_x86_64_unknown_linux_gnu         -> nerves_toolchain_x86_64_nerves_linux_gnu
nerves_toolchain_x86_64_unknown_linux_musl        -> nerves_toolchain_x86_64_nerves_linux_musl

Linux headers were downgraded from 4.14.160 to 4.4.214 to support using toolchains with systems using older versions of Linux.
