Updated to gcc 12.2, gdb 12, binutils 2.39, glibc 2.36. Upstream changed version scheme previously based on the release date (2021.07) to a version scheme based on gcc version (12.2.rel1). The runtime issue (Illegal instruction on some x86 host) [1] seems to be fixed since it can't be reproduced anymore on the same host. The x86_64 host variant prebuilt toolchain is built on RHEL7 (glibc 2.17) and is likely also be useable on OS versions like RHEL8, Ubuntu 18.04 or later. The AArch64 host variant prebuilt toolchain is built on Ubuntu 18.04 (glibc 2.27) is likely also be useable on OS versions like RHEL8, Ubuntu 18.04 or later. Use the sha256 hash that is now provided by upsteam. Tested with qemu_arm_vexpress_defconfig.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
