The CI's mingw cross-compile (--target=x86_64-w64-mingw32) has been
failing for a while at lib/gdeflate/libdeflate/lib/utils.c, where
libdeflate's compiler_gcc.h defines _rotr* as macros before mingw's
<stdlib.h> can declare them as functions. The fix is in
Catcrafts/Crafter.Asset PR #1 (commit 021ced6); pin to that SHA so
the Windows artifact jobs unblock immediately rather than waiting on
master-tracking + a merge race. Once the upstream PR is merged and
master is confirmed to carry the fix, the pin can be removed.
Adds an optional commit arg to resolveDep so the existing
"track-master" call site for Crafter.Math is unchanged.
Refs Catcrafts/Crafter.Build#6.
Linux→mingw cross-compile now produces the same architectural shape as
build.cmd (DLL + import lib + launcher exe) instead of a single static
binary. The CI Windows artifact becomes a first-class drop-in: a user
on Windows can run crafter-build.exe against any project.cpp and have
it produce real Windows binaries — for either mingw or MSVC ABI.
What changed:
project.cpp: when target=mingw or target=msvc, crafter.build-lib is
built as LibraryDynamic instead of LibraryStatic so the link emits a
DLL + import lib (matching what build.cmd produces natively).
Crafter.Build-Clang.cpp Build():
- LibraryDynamic now branches per target — mingw emits <name>.dll +
lib<name>.dll.a via lld --out-implib; msvc emits <name>.dll +
<name>.lib via /IMPLIB; unix unchanged.
- expectedOutputFor returns .dll for Windows-target dynamic libs.
- Executable on Windows host now branches per target: mingw target
uses simple link (no -lc++/-nostdlib++/LIBCXX_DIR), msvc target keeps
the existing path. Both auto-copy LibraryDynamic dep DLLs + import
libs alongside the launcher exe (Windows resolves DLLs from the exe's
own directory at load time).
- Mingw-target Executables get -D CRAFTER_BUILD_DLL_IMPORT so
CRAFTER_API resolves to dllimport in their PCMs.
- mingw link adds -static-libstdc++ -static-libgcc -Wl,-Bstatic
-lpthread so produced .exe/.dll don't depend on a particular
libstdc++-6.dll / libwinpthread-1.dll being on the consumer's PATH
(avoids the Arch UCRT vs msys2 UCRT vs msys2 MSVCRT ABI rabbit hole).
Drops the old auto-copy of /usr/x86_64-w64-mingw32/bin/*.dll which
is now dead weight.
- -r flag resolves to an absolute path before std::system, otherwise
cmd.exe rejects "./bin/..." with "'.' is not recognized...".
Crafter.Build-Platform.cpp:
- Split the Windows-host block into shared shell helpers (#if MSVC ||
MINGW) plus separate #if MSVC and #if MINGW blocks for LoadProject /
EnsureCrafterBuildPcms / GetBaseCommand / BuildStdPcm.
- Mingw-host LoadProject compiles project.cpp with --target=mingw,
--sysroot=C:\msys64\ucrt64 (default; override with CRAFTER_MINGW_DIR),
-femulated-tls, -Wl,--export-all-symbols (mingw-lld doesn't accept
/EXPORT:NAME), and links against libcrafter-build.dll.a from the
launcher's directory.
- Mingw-host GetBaseCommand and BuildStdPcm dispatch on config.target
so a mingw-host crafter-build can also build msvc-target outputs
(uses LIBCXX_DIR + libc++ headers, same as native build.cmd) when
the user sets cfg.target = "x86_64-pc-windows-msvc".
README adds a Quick start (Windows) section covering both build paths
(native MSVC via build.cmd and the cross-compiled mingw artifact),
documenting the msys2 UCRT toolchain prerequisite.
Verified end-to-end on the winvm:
- mingw target: cross-compiled crafter-build.exe builds hello-world's
project.cpp, compiles main.cpp, links a hello.exe that runs without
any custom PATH (only Windows system DLLs needed).
- msvc target: same crafter-build.exe builds an MSVC-ABI hello.exe
linked against c++.dll (auto-copied from LIBCXX_DIR), runs cleanly.

Two CI fixes from run #276 (got all the way through tests + mingw cross-
compile + packaging, only failed on artifact upload):
march: workflow now sets CRAFTER_BUILD_MARCH=x86-64-v2 / MTUNE=generic;
project.cpp reads both and applies them to the lib + exe Configurations
so the self-rebuild and mingw cross-compile honor the same baseline.
v3 is unusable on the runner — Intel N5105 (Tremont) has no AVX2, so
a v3 bootstrap binary wouldn't even start. v2 (SSE4.2) runs on the SBC
and on every x86_64 CPU since ~2011.
upload-artifact: pinned to v3. v4+ uses a GHES-only API that Forgejo
Actions doesn't implement; the v3 action stays on the older API that
Forgejo supports.

WASI / wasm32 target support
- Auto-detect /usr/share/wasi-sysroot on Linux when target starts_with("wasm32")
- Skip -march/-mtune for wasm (clang rejects them)
- Apply -fno-exceptions -fno-c++-static-destructors -mllvm -wasm-enable-sjlj
-D_WASI_EMULATED_SIGNAL to wasm builds (compile + std PCM, kept in sync)
- .wasm output extension in expectedOutputFor and link command
- EnableWasiBrowserRuntime(cfg): opt-in helper that drops index.html +
runtime.js next to the .wasm; runtime.js reads window.CRAFTER_WASM_URL
set in the templated index.html so a single shim handles any output name
-r run flag in the CLI: build then exec the artifact (host targets only;
rejects libraries; auto .exe/.wasm extension handling)
CI pipeline (.forgejo/workflows/ci.yaml)
- Triggers: PR/push to master + manual dispatch
- Single arch-latest container job: install deps, bootstrap, self-rebuild,
run tests, cross-compile mingw, package both archives, upload artifacts
- Rolling 'latest' release published only on push/dispatch to master
mingw cross-compile from Linux now works end-to-end:
- ExternalDependency cache key includes target so per-target glslang builds
don't collide; CMAKE_BUILD_TYPE=Release pinned (otherwise glslang appends
'd' to lib names and breaks linking); cross-compile cmake flags
(CMAKE_SYSTEM_NAME=Windows, CMAKE_*_COMPILER_TARGET=...)
- project.cpp accepts --target=<triple>; Linux-only -Wl,--export-dynamic
and -ldl are gated; mingw glslang skips the standalone exe (its libgcc_eh
link pulls pthread which mingw doesn't link by default)
- mingw compile uses -femulated-tls so std::__once_callable etc reference
the same emutls symbols libstdc++ provides
- mingw link auto-adds -lstdc++exp -lpthread
GetCrafterBuildHome() exposed from the Platform module; LoadProject (Linux
+ Windows) now both use it instead of duplicating the resolution.
Examples reorg: hello-world, library, with-module, wasi, tests — each with
its own README. Tests reorg: per-test directory with inner/ fixture, no
shared tests/fixtures/ tree. New Wasi test verifies .wasm magic bytes.

- subprocess-isolated test runner (replaces V1 dlopen-RunTest);
Pass/Fail/Crash/Timeout/Skipped outcomes via :Test partition
- TestRunner abstraction with command templates: Local, Ssh,
SshWin (cmd.exe-shell), QemuUser, FromEnv; probe-based skip
when runner unreachable
- transitive PCM-path propagation in Build(); resolveImport
walks deps recursively; depResults cache keyed by PcmDir()
so per-target builds don't collide
- cfg.sysroot threaded through BuildStdPcm + base compile/link
command (enables aarch64 cross via Arch Linux ARM rootfs)
- lib + exe split: project.cpp defines crafterBuildLib
(LibraryStatic) + crafterBuildExe (Executable depending on
it); build.sh produces lib/libcrafter-build.a alongside
bin/crafter-build for downstream static-link consumers
- Windows DLL+launcher: CRAFTER_API macro, /EXPORT flag for
project.dll's CrafterBuildProject; Crafter::Run as the real
entry point with main.cpp as a thin wrapper
- 18 tests: HelloWorld/WithModule/Defines/CrossProjectModule/
Diamond × (Linux + sshwin:winvm), plus Incremental,
BuildError, Libraries, RunnerClassification, QemuUser,
SshRunner, WindowsViaSsh, CrossArchAarch64
- single ./bin/crafter-build test runs everything; Windows
variants skip gracefully if winvm SSH alias unreachable
