Main's rule of 6 October 2026 from the 0.3.14 repro (docs/evidence/reproduced/0.3.14.md): prost's protowire.rs embeds OUT_DIR, libmimalloc-sys embeds __DATE__/__TIME__, sccache hid both. lib.sh bs_repro_env exports SOURCE_DATE_EPOCH=<author time> TZ=UTC in front of every remote command (build-remote.sh, cross-remote.sh, workers-remote.sh); remote-run.sh exports BR_SDE too and logs it as source_date_epoch; proto-cuda/windows-node/cross-build.sh exports the same; the PC job carries node.commit_time in the manifest (push-build-inputs.sh) and exports it before every cargo build of a stage (jobbuild.rs, unit test asserts it; 4 of 4 pass on the box). Target dirs stay one fixed path per target. tools/build-remote.sh --self-test-repro [--full] from a fork worktree, run on the box: igneum-miner twice a minute apart without sccache (RUSTC_WRAPPER=/usr/bin/env, an empty value is unset to cargo) MATCH 91e130f5..., a per-run target path differs (OUT_DIR shown); --full: kaspad with libmimalloc-sys recompiled a minute later MATCH 70219bc2..., without the epoch differs (__DATE__ shown).

# Cross-compiles igneumd.exe and igneum-miner.exe for x86_64-pc-windows-gnu on the Mac (Homebrew mingw-w64 and llvm).
|
|
# Worked on 3 October 2026 (8 min 25 s with -j 6 at nice 19 on a loaded M5 Max); see WINDOWS-MINER.md, "Run your own node".
|
|
# What each variable is for:
|
|
# CC/CXX/AR_x86_64_pc_windows_gnu the cc crate builds rocksdb (C++), snappy, zstd, lz4, bzip2, zlib, secp256k1 and
|
|
# mimalloc with the mingw compilers
|
|
# LIBCLANG_PATH librocksdb-sys runs bindgen on rocksdb/c.h; Homebrew llvm's libclang
|
|
# BINDGEN_EXTRA_CLANG_ARGS_... bindgen's clang must parse the mingw headers for the Windows target, not the Mac's
|
|
# CARGO_TARGET_..._RUSTFLAGS -static: ld takes libstdc++.a, libgcc.a and libwinpthread.a instead of the import
|
|
# libraries, so the exe does not need libstdc++-6.dll, libgcc_s_seh-1.dll or
|
|
# libwinpthread-1.dll on the PC (the first build linked libstdc++-6.dll because
|
|
# -static-libstdc++ means nothing to the gcc driver rustc links with)
|
|
# Usage: windows-node/cross-build.sh [node worktree, default vendor/igneum-node-win] [cargo jobs, default 6]

# 5 October 2026 (0.3.7): -static-libstdc++ added as a try; -static alone left libstdc++-6.dll in the import table of
|
|
# every exe so far (0.3.5's and the PC's), which is why the payload must ship the DLLs of the toolchain that linked
|
|
# the exes (push-inputs.sh takes them from next to the exes first, then from this toolchain) and why push-inputs.sh
|
|
# refuses an exe that imports a symbol the shipped DLL does not export.
|
|
# 5 October 2026 (housekeeping, after 0.3.8): the fork's database/build.rs now links libstdc++ statically on this
|
|
# target (the toolchain's libstdc++.a offered as libstdc++.dll.a in a search dir), so a node built from a fork at or
|
|
# after that commit imports no mingw DLL and the pairing rule is moot for it; the gate and the DLL copy stay for any
|
|
# older fork. The PC-built exe (GCC 13) died at its first rocksdb call with the dynamic runtime; see the

|
# release-0.3.6 plan, section 10.
