The smoke-test caught the aarch64 binary linking a /nix/store libiconv.dylib
— non-portable (won't exist on a user's Mac). The Apple SDK already provides
a system libiconv stub, so removing pkgs.libiconv makes the linker resolve
-liconv to /usr/lib instead. The smoke-test now fails if any /nix/store dylib
is linked.
Add the two *-apple-darwin targets to rust-toolchain.toml and apple-sdk +
libiconv to the flake devShell (darwin only) so the nix toolchain links
AppKit; make cargo-zigbuild/zig Linux-only (macOS builds natively). Repoint
the throwaway macOS workflow to actually build both darwin targets through
the flake on the Tart runner — the first real check of the macOS leg, which
can't be verified locally. Delete once release-macos lands.
Replace the single-target musl cc with cargo-zigbuild + zig in the flake
devShell — one universal cross cc/linker (incl. rusqlite's bundled SQLite
C) for all four non-macOS D1 targets, added to rust-toolchain.toml:
x86_64/aarch64-unknown-linux-musl (static, D2)
x86_64-pc-windows-gnu, aarch64-pc-windows-gnullvm (standalone .exe)
Windows links -lsynchronization (std WaitOnAddress), which rust-overlay's
toolchain and zig's mingw don't ship; the symbols are forwarded by
kernel32, so an empty stub libsynchronization.a (ci/winstub/, wired via
.cargo/config.toml for the windows targets only) satisfies the linker.
Verified: all four build; linux static; windows valid PE32+.
rust-toolchain.toml gains the x86_64-unknown-linux-musl target; the
flake devShell gains a musl cc (pkgsCross.musl64) + CC/linker env so a
`cargo build --target …-musl` compiles rusqlite's bundled SQLite C and
links fully static (D2: single static binary, no runtime deps). Cargo
release profile strips symbols (13MB -> 10MB). Verified locally: the
musl binary is static-pie, statically linked, stripped, runs standalone.
Root flake with two outputs: devShells.default (pinned 1.95.0
toolchain via rust-toolchain.toml + rust-overlay, plus cargo-sweep)
and packages.default (rustPlatform.buildRustPackage from the committed
Cargo.lock; doCheck=false). flake.lock pins nixpkgs nixos-26.05 /
rust-overlay / flake-utils. .envrc (use flake) for direnv parity.
Single source of toolchain for dev and the upcoming CI, so they can't
drift. Verified through the flake: nix build yields a working binary,
clippy clean, 2424 tests pass / 0 fail / 1 intentional ignored doctest.
First step toward requirements.md TT5 + D1/D2/D3.
