On a fresh checkout, make -C depends PLATFORM_GUI=1 never invokes vendor-platform_cxx-crates, and the vendored archive is not one of platform_cxx's fetched sources. Silently skipping this block therefore leaves Cargo without .cargo/config.toml or the vendored registry, after which the package's cargo build --offline cannot resolve its dependencies. The CI workflow happens to generate or restore the archive separately, but the documented depends knob is unusable for ordinary fresh builds unless the archive is made a prerequisite or generated as part of the normal build graph.

When cross-building a Darwin target in the Guix environment, depends/hosts/darwin.mk deliberately prefixes the compiler with env -u C_INCLUDE_PATH -u CPLUS_INCLUDE_PATH; taking only firstword consequently sets Rust's linker to env, not to clang, so rustc invokes env with linker arguments and the Platform library cannot link. Even outside that environment this also discards the Darwin compiler's --target and sysroot arguments, so the Rust linker should use a wrapper that retains the complete configured compiler command.

Running the newly documented contrib/devtools/update-rust-hashes.py in this commit always exits here because the repository contains no rust-toolchain.toml; configure.ac also has no RUSTC_REQUIRED_VERSION assignment for the later update. As a result, maintainers cannot use the script to update either of the Rust depends pins it was added to maintain. Limit synchronization to files present in this change, or add the expected consumer files before making them mandatory.
Useful? React with 👍 / 👎.
WalkthroughThe change adds Platform GUI dependency packages, Rust compiler and standard-library downloads, Cargo vendoring, and offline Platform C++ builds. It adds configure-site integration and Guix ELF interpreter patching. CI now caches or transfers Rust vendor archives and runs dedicated Linux Platform GUI dependency, source-build, and test jobs. A utility updates Rust archive hashes and version pins. Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The PR adds an offline, pinned Rust/platform dependency build path. It is mergeable with explicit owner follow-up because the hash-update utility could leave pins inconsistent after a partial failure or hang on a stalled download, potentially disrupting future dependency builds.

Preliminary review — Codex only
The opt-in Platform build is not self-contained on a clean checkout because the required crate archive is outside the normal dependency graph, and Guix Darwin cross-builds select env rather than Clang as rustc's linker. The Rust hash updater is also unusable at this head because it unconditionally requires consumer-side files that are not present.

Fixed in e42c902. The archive is now a real file target — $(SOURCES_PATH)/<package>-vendored.tar.gz, with the vendor recipe as its rule — and a hard prerequisite of both the package's preprocess stamp and download-one, so neither a clean make -C depends PLATFORM_GUI=1 nor make download can reach the offline cargo build without it; vendor-<package>-crates remains as a phony alias. Extraction is now unconditional (the if test -f skip is gone), and because the stamp depends on the archive by mtime, creating the archive after a failed attempt re-triggers preprocessing instead of being ignored.
Verified locally from a fully clean tree (no work dir, no prefix, archive deleted): make auto-vendored during the dependency walk, then completed the locked offline cargo build and cached the package.

Fixed in e42c902 (machinery) and 97c428a (package patch). RUSTFLAGS now points rustc's linker at a rustc-linker.sh installed from the package's patches during preprocessing, which exec $CC "$@" — cargo's environment already carries the full configured compiler command line, including the Guix env -u C_INCLUDE_PATH -u CPLUS_INCLUDE_PATH prefix and the target/SDK arguments, so nothing is lost to firstword. Build scripts are unaffected: cargo applies RUSTFLAGS only to cross-target units when --target is passed.
(An earlier iteration generated the script from an inline echo; that ran into make treating #!/bin/sh's # as a comment inside the variable, so the wrapper ships as a patch file like cargo-config.toml, which also keeps it in the package's recipe hash.)

Fixed in e42c902. The script now synchronizes only the two depends package files (native_rust.mk hashes, rust_stdlib.mk hashes and version) and no longer requires or edits rust-toolchain.toml / configure.ac — those consumers don't exist at this revision. If a later PR introduces an in-tree Rust consumer, re-adding that synchronization can come with it.

native_rust installs the pinned prebuilt Rust toolchain as a native package and rust_stdlib provides the precompiled standard library for every supported cross target; contrib/devtools/update-rust-hashes.py maintains both pins together. funcs.mk gains a cargo environment wired to the depends cross toolchain and a per-package crate-vendoring template: any package that declares a vendored archive name and a cargo manifest gets its vendored-crate archive modeled as a real make target, created by cargo vendor when absent and required by the package's preprocess stamp and by make download, so a clean build can never reach the offline cargo build without vendored sources. Preprocessing extracts the archive and generates a rustc linker wrapper that preserves the full configured compiler command (target and sysroot flags, and any env prefix), since -C linker= takes a single executable.
…I knob
PLATFORM_GUI=1 adds mbedtls, native_protobuf, tenderdash_sources and platform_cxx to the package set. platform_cxx builds libdash_platform_cxx.a and its installed headers from a pinned dashpay/platform commit (packages/rs-platform-cxx), offline via the per-package vendored crates. config.site.in exports enable_platform_gui and PLATFORM_CXX_{CFLAGS,LIBS} discovery for the configure flag that arrives with the first C++ consumer.
…lane The new lane builds depends with PLATFORM_GUI=1 (producing and hash-verifying the Platform CXX archive offline from vendored crates), then builds dash-qt against that prefix and runs the unit tests. The cache-sources producer generates and caches the platform-cxx vendored-crates archive, handing it to same-run consumers as an artifact on cache miss. The --enable-platform-gui configure flag is added to this lane's BITCOIN_CONFIG by the Platform client library PR; until then the lane proves the depends knob and prefix link-compatibility. build.yml runs PR validation from the base branch (pull_request_target), so the lane first runs on push CI for this branch and takes effect for PRs after merge.

When PLATFORM_GUI=1 is built inside the project's Guix environment, ls resolves under /gnu/store, so this branch exits unless patchelf is available; however, the package list in contrib/guix/manifest.scm does not include patchelf. Consequently, the new native_rust package cannot reach its staging step in a Guix build. Add patchelf to the Guix manifest or avoid making it mandatory there.

If one of these downloads is interrupted, or an existing archive is corrupt, the destination file remains in place; every subsequent make PLATFORM_GUI=1 download takes the -f branch, fails the checksum, and never invokes the downloader again. Use the existing temporary-download-and-rename pattern (or delete a file after a checksum mismatch) so the depends source cache can recover without manual cleanup.

Preliminary review — Codex only
The three prior findings are fixed at the exact head: vendoring is now part of the build graph, the Rust linker wrapper preserves the complete compiler command, and the hash updater only references present consumers. Two new blockers remain in the Guix path because the manifest provides neither the mandatory patchelf executable nor the libz runtime required by the pinned Rust compiler; the all-target Rust stdlib downloader also cannot recover from a partial or corrupt cached archive.

DashPay (the Platform GUI: usernames, contacts, contact payments) needs GroveDB proof verification, DPP document handling and state-transition construction from Dash Platform's own Rust implementation. Per the architecture decision on the composite branch, that Rust code lives in the Platform repository (dashpay/platform#4416,
packages/rs-platform-cxx) and Dash Core consumes it as a prebuilt static library — no Rust code is vendored into this repository.This PR is the build foundation for that: it teaches depends to produce
libdash_platform_cxx.aand its headers from a pinned dashpay/platform commit, fully offline and hash-verified.What was done?
native_rust/rust_stdlib: pinned prebuilt Rust toolchain as a native package plus the precompiled standard library for every supported cross target;contrib/devtools/update-rust-hashes.pymaintains both pins together.funcs.mk: any package declaring a vendored archive name and cargo manifest gets avendor-<package>-cratestarget; builds then runcargo build --locked --offlineagainst the extracted archive.PLATFORM_GUI=1knob: addsmbedtls,native_protobuf,tenderdash_sourcesandplatform_cxxto the package set.platform_cxxbuilds the Platform CXX bindings from the pinned commit and installslib/libdash_platform_cxx.a+include/dash/platform/.config.site.inexportsenable_platform_guiandPLATFORM_CXX_{CFLAGS,LIBS}for the configure flag that arrives with the client library PR.linux64_platform_guilane builds depends with the knob on (generating/caching the vendored-crates archive in the cache-sources producer) and builds dash-qt against the enriched prefix. Notebuild.ymlvalidates PRs with the base branch's workflow (pull_request_target), so the lane runs on this branch's push CI now and takes effect for PRs once merged: see the push CI run.Default path is untouched: with the knob off, the depends package set is byte-identical to develop (
make -C depends print-packages).Pin caveat:
platform_cxxcurrently pins dashpay/platform#4416's head (df4fdb68559e). That PR is stacked on dashpay/platform#4388/#4389; once it merges tov4.2-devthe pin + hash here will be refreshed to the merged commit before this PR merges (or as an immediate follow-up if we choose to merge sooner).How Has This Been Tested?
