build: target aarch64 over armv7, add rudimentary support for Rust components in build system, update to macOS SDK 15.0 (from Xcode 16.0)

[kwvg]

Additional Information

• Depends on backport: merge bitcoin#30423, #27038, #31048, #31099, #31172, #31450, #31608, #31818, #29881, #32458, #32400, #32760, #33178, #33312, #33780, #33181, #34102, partial bitcoin#29023, #30454, #30509, #30510, #31105, #32922, #33489, #33445 (build backports: part 5) #6927

• To ensure our list of targets validated are matched with targets used for releases (see guix-start), we switch out arm-linux-gnueabihf with aarch64-linux-gnu, this is now reflected by changes to our GitHub CI configuration, build scripts, Guix CI action.

  • Additionally, since dash#7047, we can't assume our host is x86_64 and must update packages to explicitly mention the desired arch instead of relying on that assumption.

• On top of ntdll.dll, Rust's standard library has a hard dependency on api-ms-win-core-synch-l1-2-0.dll (sync primitives) after rust-lang/rust#124019, which has been added to the allowlist even though this dependency isn't specified in RUST_LIBS.

• The build system passes information about the host compiler, target macOS version and other parameters as Rust crates themselves may be FFI bindings to C/C++ codebases, this is specifically relevant for cross-compilation where host and target do not match. depends exposes whatever is needed but if attempting to build without depends, the following environment variables need to be defined.

  • OSX_MIN_VERSION (target version of macOS)
  • OSX_SDK (path to the macOS SDK)
  • NATIVE_AR (host archiver)
  • NATIVE_CC (host C compiler)
  • NATIVE_CXX (host C++ compiler)
  • RUST_NATIVE (host Rust target, if cannot be deduced by build system)

• For integrating the crates into our C++ codebase, we use the cxx crate with the version defined in native_cxxbridge.mk

  • As mentioned in dash#6927, we need to update the macOS SDK to ensure we have standards-conformant definitions to deal with dtolnay/cxx#1574.

  • This does result in us using a higher SDK version than used upstream, requiring us to update the source URLs to our own fallback servers as upstream is not expected to host this version of the consolidated SDK. This has no effect on the target version of macOS, which will continue to be macOS 14.

• The version of Rust defined in native_rust.mk and rust-toolchain.toml must match as the former is what we use in depends (and is the same version used in the Guix environment, we don't rely on Guix to supply us a Rust build environment) and the latter is used to ensure that builds outside depends use a matching Rust version.

  • The version should also be synced with rust_stdlib.mk, which defines the standard libraries used. All hosts (native_rust) will have a target (rust_stdlib) but not all targets will have a host. Version management is done using contrib/devtools/update-rust-hashes.py and contrib/devtools/update-native-cxxbridge.py.

    • To avoid glibc-related issues in Guix builds due to conflicting versions, incompatible symbols or the mixing of code generated with different glibc targets, we have opted to use the musl variant of the standard library for Linux builds. Non-depends builds will need to configure their Rust environment accordingly.

    • To allow PowerPC target builds, we had to move from Rust 1.82 (the minimum version demanded by cxx) to 1.85.1

  • This also means that the CI Docker image does not have a Rust compiler as it is supplied by depends. This is done due to the fact that we already need a depends-supplied compiler to have greater control over version and variant but also to avoid increasing the size of our already-large master image.

    Future work on the CI system could provide Rust compilers to aid in debugging and development (as development images are derived from CI images) but that is out of scope for this PR.

• The depends system introduces the following verbs

  • download-rust-src (downloads packages necessary for vendoring)

  • download-rust-std (downloads the standard library for all targets listed in rust_stdlib.mk, needed as Guix environments do not have access to the internet)

  • vendor-dep-crates (vendors dependencies by Rust packages in the depends system)

  • vendor-all-crates (vendors dependencies by Rust packages used in the codebase)

    • During development and when building without the depends system, you will need to use --enable-online-rust, failing which, you will need to define RUST_VENDORED_SOURCES (a value that is otherwise defined by the depends system).

    • Vendoring support was added as Guix environments have no access to the internet and to allow for caching crates for CI.

• As the Guix environment does not use normal paths, we have to do the inverse of the patch that is usually done to binaries generated in Guix environments (replacing the loader with standard paths instead of store-specific paths) to ensure our native binaries will run and additionally locate the GCC runtime (libgcc_s.so.1) and move it to a location reachable to the native binaries and patch that patch too.

  This is done using contrib/guix/libexec/fix-elf-interpreter.sh and is meant only for the Guix environment as it assumes that it will always run on a Linux host.

How Has This Been Tested?

Running dashd or dash-qt should have this entry in their debug log (see below) demonstrating a call to the stub crate during init.

225-227: ⚠️ Potential issue | 🟡 Minor

Documentation does not match actual HOSTS defaults in guix-build.

The README lists outdated defaults. The actual HOSTS in guix-build (line 84-86) includes riscv64-linux-gnu and excludes the disabled powerpc64le-linux-gnu, but the documented defaults omit the former and include the latter. Additionally, arm-linux-gnueabihf remains in both the actual defaults and documentation.

113-116: NATIVE_AR always overrides a user-set value, unlike NATIVE_CC/NATIVE_CXX.

NATIVE_CC and NATIVE_CXX are guarded with -a -z "${NATIVE_CC}" so a user-provided value is preserved. NATIVE_AR follows the existing (non-native) AR pattern of always overriding. This is internally consistent within each pair, but the asymmetry across the three native tool variables may surprise callers who pre-set NATIVE_AR.

In @.gitignore:
- Around line 179-200: Remove the unanchored, overly-broad entries: delete the
bare "debug" entry, replace the bare "target" with a rooted "/target" (or
explicitly ignore "/target/debug" if you only mean build artifacts), and replace
the bare "gen" with a rooted form like "/gen" or "/gen/" so the ignores only
apply to top-level build/generated dirs; update the .gitignore entries
referencing "debug", "target", and "gen" accordingly.

In `@contrib/guix/README.md`:
- Line 252: The README line references Xcode 16.0 (build `16A242d`) but claims a
macOS SDK 15.2; update that example to reference the correct Xcode build that
contains macOS SDK 15.2 by replacing the string containing
`Xcode-16.0-16A242d-extracted-SDK-with-libcxx-headers` (the
`$HOME/Downloads/...` path) with the Xcode 16.2 build identifier and SDK name
(e.g., `Xcode-16.2-16C5032a-extracted-SDK-with-libcxx-headers` and `macosx15.2`)
so the documented SDK identifier matches the claimed SDK version.

In `@contrib/macdeploy/README.md`:
- Line 18: The README currently references Xcode_16.xip but incorrectly states
SDK 15.2; either update the PR title/description to indicate SDK 15.0/Xcode 16.0
(build 16A242d) or switch the referenced artifact to Xcode 16.2 (build 16C5032a)
to truly target SDK 15.2; if switching to Xcode 16.2, update the tarball name
and the sha256 values accordingly (the generated tarball name and its sha256
must match the Xcode 16.2 release), and verify that the sha256 hashes shown (the
entries near lines referencing the hash values) were produced from a clean
extraction of the exact Xcode release you choose.

binary name "x86-64-linux-gnu-gcc"; update the linker value to the correct
cross-compiler executable "x86_64-linux-gnu-gcc" (replace the hyphen between x86
and 64 with an underscore) so the linker resolves correctly.

- Around line 1753-1760: The fallback to $(sw_vers -productVersion) for
RUST_MACOS_DEPLOYMENT_TARGET can fail during cross-compilation; update the block
that sets RUST_MACOS_DEPLOYMENT_TARGET so it only calls sw_vers when
OSX_MIN_VERSION is unset AND the build is actually running on macOS and sw_vers
exists (similar guard used around RUST_OSX_SDK). In practice, replace the
unconditional fallback with a conditional that checks the host is darwin and
that command -v sw_vers >/dev/null succeeds before invoking sw_vers, otherwise
leave RUST_MACOS_DEPLOYMENT_TARGET empty (or unchanged).
- Around line 1743-1751: The current case block appends -ldl for all non-mingw
hosts (the RUST_LIBS assignment inside the case $host block), which wrongly
applies to macOS/FreeBSD; change the pattern matching so -ldl is only added for
Linux hosts (e.g., replace the *) branch that sets RUST_LIBS="$RUST_LIBS -ldl"
with an explicit pattern like *linux* or *linux*|*gnu*), and add a separate
default/no-op branch for other OSes (macOS/FreeBSD) so they do not receive -ldl.
- Around line 130-143: RS_REQUIRE_PROG currently leaves shell expansions
unquoted and uses a double-quoted AC_MSG_ERROR; update the macro so the test
uses quoted expansions (e.g. test "x${$1}" = "x${2_notfound}" or equivalent
quoted forms) to handle paths with spaces, and change the error call to use m4
square-bracket quoting for AC_MSG_ERROR (AC_MSG_ERROR([Required program $2 was
not found])) so the message is properly quoted by autoconf; keep the same
symbols RS_REQUIRE_PROG, AC_PATH_PROG and AC_MSG_ERROR when making the change.

In `@contrib/devtools/update-native-cxxbridge.py`:
- Around line 56-57: The call to tar.extractall(tmp_path) is vulnerable to path
traversal; update the extraction in the tarfile.open block to use a safe filter
(e.g., pass filter="data" when calling tar.extractall) or otherwise validate
members' paths before extraction so extracted files cannot escape tmp_path;
locate the tarfile.open(...) as well as tar.extractall(tmp_path) and change the
extraction to use the filter="data" argument (or implement an explicit member
path-sanitization routine) referencing tarfile.extractall, tarfile.open,
tarball_path and tmp_path.

In `@contrib/guix/symbol-check.py`:
- Around line 151-159: The PE_ALLOWED_LIBRARIES set has continuation-line
indentation that triggers Flake8 E122; fix the indentation of the items inside
PE_ALLOWED_LIBRARIES so continuation lines are either aligned under the opening
brace or use a consistent hanging indent (e.g., indent the subsequent lines to
match the first element or use 4 spaces), ensuring each string literal like
'ADVAPI32.dll', 'api-ms-win-core-synch-l1-2-0.dll', etc. is properly aligned and
the closing brace lines up correctly with the opening brace.
- Around line 244-247: The function check_MACHO_sdk currently compares
binary.build_version.sdk to [15, 0, 0] but the PR updates the SDK to 15.2;

"download-stamps/.stamp_fetched-rust_stdlib-$(rust_stdlib_version)-$(rust_stdlib_sha256_hash_$(1)).hash"
target) when the verification succeeds; on verification failure, fail the rule
and do not create the stamp.
- Around line 329-339: The tar extraction in the int_cargo_preprocess_ext macro
uses $(build_TAR) -P -xf $(SOURCES_PATH)/$($(1)_vendored_file_name) which can
preserve ownership when run as root; update the command inside
int_cargo_preprocess_ext to include --no-same-owner (matching other extractions)
so it becomes $(build_TAR) --no-same-owner -P -xf ... to avoid
permission/ownership problems when extracting vendored crates.

In `@rust/Makefile.chirp.include`:
- Around line 46-52: The Makefile recipe for target LIBRUST_CHIRP_H has mixed
leading whitespace in the else branch (the $(CXXBRIDGE) invocation): remove the
leading spaces and ensure the recipe line begins with a single tab character so
all recipe lines under the if/else use a proper leading tab; verify similar
recipe lines (the cp and the $(CXXBRIDGE) lines) start with tabs and not spaces
to avoid Makefile parsing issues (references: LIBRUST_CHIRP_H,
LIBRUST_CHIRP_GEN_SRCDIR, CXXBRIDGE).

Nitpick comments:
In `@contrib/devtools/update-native-cxxbridge.py`:
- Around line 69-72: The subprocess.run call that invokes cargo (the call
assigning to result using subprocess.run([...], cwd=cxx_dir)) does not capture
stderr, so failures lack diagnostic output; modify this call to capture output
(e.g., add capture_output=True or stdout=subprocess.PIPE,
stderr=subprocess.PIPE) and on non-zero return (result.returncode != 0) log or
raise including result.stderr (and optionally result.stdout) so failing cargo
check emits the command output for debugging.

In `@depends/config.site.in`:
- Around line 177-186: RUST_VENDORED_SOURCES is being set unconditionally which
can pass a non-existent path into configure; change it to mirror the conditional
pattern used for CARGO, RUSTC, and CXXBRIDGE by only setting
RUST_VENDORED_SOURCES when "${depends_prefix}/vendored-sources" exists (test -d)
— use the same depends_prefix variable and add a conditional block that assigns
RUST_VENDORED_SOURCES only if the directory is present, leaving it unset
otherwise.
- Around line 113-116: The NATIVE_AR assignment always overrides a user-provided
value unlike NATIVE_CC/NATIVE_CXX; update the block that sets NATIVE_AR and
ac_cv_path_NATIVE_AR so it only assigns when `@NATIVE_AR`@ is non-empty and the
user hasn't already set NATIVE_AR (i.e., add the same test pattern used for
NATIVE_CC/NATIVE_CXX such as checking -n "@NATIVE_AR@" and -z "${NATIVE_AR}"
before setting NATIVE_AR and ac_cv_path_NATIVE_AR) to preserve pre-set NATIVE_AR
values.

In `@depends/patches/native_rust/fix-elf-interpreter.sh`:
- Around line 54-61: The script copies LIBGCC_REAL to $LIBDIR but doesn't ensure
$LIBDIR exists, causing cp to fail; update the block that uses LIBGCC_SRC,
LIBGCC_REAL and LIBDIR to create the destination directory first (e.g., run
mkdir -p "$LIBDIR" before cp) and handle errors (exit or warn) if mkdir or cp
fails so the subsequent cp "$LIBGCC_REAL" "$LIBDIR/libgcc_s.so.1" is robust.

⚠️ Potential issue | 🟡 Minor

Overly broad unanchored ignore patterns (debug, target, gen).

• debug (line 181): Cargo never creates a standalone top-level debug/ directory (debug artefacts live under target/debug/), so this entry is both redundant and risks silently hiding any debug/ directory that might appear elsewhere in the repo.
• target (line 182): Without a leading /, this matches every target/ directory in the entire tree (e.g. src/target/, contrib/target/, etc.). Standard Rust .gitignore templates use the rooted /target form.
• gen (line 200): Bare name with no leading / and no glob qualifier – would silently hide any file or directory named gen anywhere in the repository.

🔧 Suggested tightening

-debug
-target

In @.gitignore around lines 179 - 200, Remove the unanchored, overly-broad
entries: delete the bare "debug" entry, replace the bare "target" with a rooted
"/target" (or explicitly ignore "/target/debug" if you only mean build
artifacts), and replace the bare "gen" with a rooted form like "/gen" or "/gen/"
so the ignores only apply to top-level build/generated dirs; update the
.gitignore entries referencing "debug", "target", and "gen" accordingly.

⚠️ Potential issue | 🟡 Minor

Unconditional patchelf verification on $1 will error when no binaries are supplied.

After the shift at line 8, $1 is the first binary argument. If the script is invoked with only LIBDIR and no binary arguments, $1 is empty and both patchelf calls fail, leaving the script with a non-zero exit code. Guard the verification block:

🐛 Proposed fix

-echo "Verifying first binary:"
-patchelf --print-interpreter "$1"
-patchelf --print-rpath "$1"
+if [ -n "$1" ]; then
+    echo "Verifying first binary:"
+    patchelf --print-interpreter "$1"
+    patchelf --print-rpath "$1"

In `@depends/patches/native_rust/fix-elf-interpreter.sh` around lines 75 - 77, The
verification block unconditionally runs patchelf on "$1" after the initial
shift, which causes errors when no binaries were passed; modify the script so
the two commands (patchelf --print-interpreter "$1" and patchelf --print-rpath
"$1") are only executed when "$1" is non-empty (i.e., after shift check that at
least one binary argument exists), guarding the verification with a simple
conditional that skips the patchelf calls when there are no binary arguments.
