Buildroot commit97e2f63bdfin 2026.02-rc1 bumped bpftrace from 0.23.3 to 0.24.2. This release includes upstream commitd4f5838227which was added to version 0.24.0 and makes use of btf_enum64 that was added to the linux kernel in version 6.0:6089fb325ccausing build errors when the toolchain contains kernel headers between versions 5.12 and 5.19 because the libbpf package does not update their headers so we need to raise the BR2_TOOLCHAIN_HEADERS_AT_LEAST_ version number again. The build error can be reproduced with this defconfig BR2_aarch64=y BR2_KERNEL_HEADERS_VERSION=y BR2_DEFAULT_KERNEL_VERSION="5.11.22" BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_5_11=y BR2_TOOLCHAIN_BUILDROOT_CXX=y BR2_PER_PACKAGE_DIRECTORIES=y BR2_PACKAGE_BPFTRACE=y on the 2026.02.x branch as of0be927b89a.

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 https://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.
