Since the bump to version 20260817.0, the AES-based hash for long strings is used whenever __SSE4_2__ and __AES__ are defined. It relies on _mm_cvtsi128_si64() and _mm_extract_epi64(), which are only available on x86_64, so the build fails on 32-bit x86 for CPUs that support SSE4.2 and AES: hash.cc:115:32: error: '_mm_cvtsi128_si64' was not declared in this scope Add a patch from a pending upstream pull request restricting this code path to x86_64.

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.
