objtool built by the kernel requires libelf ldd output/build/linux-6.1.24/tools/objtool/objtool linux-vdso.so.1 libelf.so.1 => output/host/lib/libelf.so.1 While updating the kernel [1] we forgot to select BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF to provide Buildroot's host-libelf. Using host-libelf avoid linking with libelf installed on the host or failing to build objtool if libelf is not installed.

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.
