I've done a test build of the rust \nbootstrap and a few packages with that and everything worked, so series\n\nTested-by: Marcus Hoffmann \n\nI did noticed that quite a few things during the bootstrap get built \ntwice. Once in the host-rustc-build step and then again in \nhost-rustc-install. Do you know why this is the case? This (sometimes?) \nhappens for normal rust packages as well, but during the many-hour long \nbootstrap it was especially noticeable here.\n\nOn 4/11/26 00:42, Nicolas Serafini via buildroot wrote:\n> Apologies for the resend, my previous submission bounced as I was\n> not subscribed to the mailing list with this email address.\n> \n> Rust remained at version 1.88.0 because, starting from version\n> 1.89.0, the bootstrap process was redesigned, and attempting to\n> bootstrap host-rust from source resulted in the following errors:\n> \n> error[E0463]: can't find crate for `std`\n> error[E0463]: can't find crate for `core`\n> \n> Several attempts to bump Rust were submitted but none were merged:\n> - Bernd Kuhls, bump to 1.92.0 (Dec 2025)\n> https://patchwork.ozlabs.org/project/buildroot/patch/20251218222527.3861751-1-bernd@kuhls.net/\n> - Simon Richter, bump to 1.93.1 (Feb 2026)\n> https://patchwork.ozlabs.org/project/buildroot/patch/20260226073135.64960-1-simon@sinic.eu/\n> \n> This series bump Rust to 1.94.1 and fixes the bootstrap issue:\n> [1/4] Bump Rust from 1.88.0 to 1.94.1\n> [2/4] Fix the bootstrap build for Rust >= 1.89.0: set\n> local-rebuild = true in config.toml and replace the broken\n> relative symlinks in host-rust-bin with hardlink copies.\n> [3/4] Bump the cargo vendor suffix from -cargo4 to -cargo5 and\n> update SHA256 hashes for all 34 affected packages, as the\n> vendored content changed following the Rust bump.\n> [4/4] Add riscv64gc-unknown-linux-musl target support, rebased\n> from Mariusz Bialonczyk's earlier patch (Oct 2025) and\n> also part of the patch series for the bump to 1.92.0:\n> https://patchwork.ozlabs.org/project/buildroot/patch/20251028045833.2792350-1-manio@skyboo.net/\n> https://patchwork.ozlabs.org/project/buildroot/patch/20251218222527.3861751-3-bernd@kuhls.net/\n> \n> Tested with:\n> utils/docker-run support/testing/run-tests \\\n> -k -d dl -o output_folder tests.package.test_rust\n> \n> Nicolas Serafini (4):\n> package/rust: bump version to 1.94.1\n> package/rust{,-bin}: fix bootstrap build for Rust >= 1.89.0\n> package: update cargo suffix to -cargo5 and fix hashes\n> rust: add support for riscv64gc-unknown-linux-musl target\n> \n\nBest,\nMarcus","headers":{"Return-Path":"","X-Original-To":["incoming-buildroot@patchwork.ozlabs.org","buildroot@buildroot.org"],"Delivered-To":["patchwork-incoming-buildroot@legolas.ozlabs.org","buildroot@buildroot.org"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=buildroot.org header.i=@buildroot.org\n header.a=rsa-sha256 header.s=default header.b=jZaEfRUz;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=buildroot.org\n (client-ip=2605:bc80:3010::138;
