Bootlin toolchains 2022.08 released

Bootlin toolchains 2022.08The toolchains.bootlin.com service provides freely available pre-compiled cross-compilation toolchains for a wide range of CPU architectures and configurations.

We have just published version 2022.08 of these toolchains, which are now built using Buildroot 2022.08. Thanks to this the toolchains now use the following components:

  • The bleeding-edge toolchains are based on gcc 12, binutils 2.39, gdb 12, kernel headers 5.4, glibc 2.35 or musl 1.2.3 or uclibc-ng 1.0.42.
  • The stable toolchains are based on gcc 11, binutils 2.38, gdb 11, kernel headers 4.9, glibc 2.35 or musl 1.2.3 or uclibc-ng 1.0.42.

Even though glibc 2.36 has been recently released, it still caused too many issues to be integrated in this toolchain release. glibc 2.36 will be part of a future update of these toolchains.

We also have a few new toolchains that appeared:

  • Toolchains for the OpenRISC CPU architecture, based on the glibc C library. We already had toolchains for OpenRISC, but not using glibc.
  • We now have both stable and bleeding-edge toolchains for the x86-64-v2, x86-64-v3 and x86-64-v4 architecture variants. We used to have only bleeding-edge toolchains for these variants as only the latest gcc had support for them.

The only toolchain that was not updated as part of this release is the m68k Coldfire toolchain, as we currently have a regression on elf2flt. This will hopefully be adressed in the future.

If you have feedback or encounter any issue in using these toolchains, the project issue tracker is where you should go.
