From 9af432a5ded06593fd91f8a283d43354af690763 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 28 Jan 2026 01:28:03 +0000 Subject: [PATCH 01/41] Add Windows/MinGW support - Update Makefile with platform detection for Windows/MinGW/MSYS2 - Add HML_WINDOWS preprocessor macro - Configure Windows-specific libraries (-lws2_32, no -ldl) - Set up platform-specific LDFLAGS - Add Windows compatibility to runtime builtins - Windows socket abstraction (Winsock2 initialization, closesocket) - Directory iteration via FindFirstFile/FindNextFile - Dynamic library loading via LoadLibrary/GetProcAddress - Clock/time functions using Windows API - Compatibility macros for POSIX functions (access, getcwd, etc.) - Add Windows compatibility to interpreter builtins - Signal handling using signal() instead of sigaction() - Platform-specific includes and function mappings - realpath() implementation via GetFullPathNameA - Add Windows compatibility to compiler codegen - basename/dirname implementations for Windows - open_memstream fallback using tmpfile - Update test runner to skip Windows-incompatible tests - Signal tests, fork tests, Unix socket tests, termios tests - Platform detection for MSYS/MinGW/Cygwin - Add docs/WINDOWS_SUPPORT.md with build instructions and API docs https://claude.ai/code/session_01YL2nKyNmSwkQ7DicdGCrvn --- Makefile | 40 ++- docs/WINDOWS_SUPPORT.md | 184 ++++++++++++++ runtime/src/builtins_async.c | 4 +- runtime/src/builtins_ffi.c | 59 ++++- runtime/src/builtins_internal.h | 253 +++++++++++++++++-- runtime/src/builtins_socket.c | 57 ++++- src/backends/compiler/codegen_internal.h | 89 ++++++- src/backends/interpreter/builtins/internal.h | 196 +++++++++++++- src/backends/interpreter/builtins/signals.c | 21 ++ tests/run_tests.sh | 59 +++++ 10 files changed, 918 insertions(+), 44 deletions(-) create mode 100644 docs/WINDOWS_SUPPORT.md diff --git a/Makefile b/Makefile index 9adefeb3..003cb719 100644 --- a/Makefile +++ b/Makefile @@ -1,15 +1,26 @@ CC = gcc -# Use _DARWIN_C_SOURCE on macOS for BSD types, _POSIX_C_SOURCE on Linux +# Platform detection +UNAME := $(shell uname 2>/dev/null || echo Windows) + +# Use platform-specific flags ifeq ($(shell uname),Darwin) CFLAGS = -Wall -Wextra -std=c11 -O3 -g -D_DARWIN_C_SOURCE -Iinclude -Isrc -Isrc/frontend -Isrc/backends -Isrc/shared $(EXTRA_CFLAGS) + PLATFORM = macos +else ifeq ($(findstring MINGW,$(UNAME)),MINGW) + CFLAGS = -Wall -Wextra -std=c11 -O3 -g -DHML_WINDOWS -Iinclude -Isrc -Isrc/frontend -Isrc/backends -Isrc/shared $(EXTRA_CFLAGS) + PLATFORM = windows +else ifeq ($(findstring MSYS,$(UNAME)),MSYS) + CFLAGS = -Wall -Wextra -std=c11 -O3 -g -DHML_WINDOWS -Iinclude -Isrc -Isrc/frontend -Isrc/backends -Isrc/shared $(EXTRA_CFLAGS) + PLATFORM = windows else CFLAGS = -Wall -Wextra -std=c11 -O3 -g -D_POSIX_C_SOURCE=200809L -D_DEFAULT_SOURCE -Iinclude -Isrc -Isrc/frontend -Isrc/backends -Isrc/shared $(EXTRA_CFLAGS) + PLATFORM = linux endif SRC_DIR = src BUILD_DIR = build -# Detect libffi, OpenSSL, and libwebsockets (Homebrew on macOS puts them in non-standard locations) -ifeq ($(shell uname),Darwin) +# Detect libffi, OpenSSL, and libwebsockets (platform-specific detection) +ifeq ($(PLATFORM),macos) # On macOS, prefer Homebrew's libffi (system pkg-config points to SDK without headers) BREW_LIBFFI := $(shell brew --prefix libffi 2>/dev/null) ifneq ($(BREW_LIBFFI),) @@ -35,6 +46,23 @@ ifeq ($(shell uname),Darwin) else HAS_LIBWEBSOCKETS := 0 endif + # macOS base libraries + LDFLAGS_BASE = -lm -lpthread -lffi -ldl -lz -lcrypto + +else ifeq ($(PLATFORM),windows) + # On Windows/MinGW, use pkg-config if available + LIBFFI_CFLAGS := $(shell pkg-config --cflags libffi 2>/dev/null) + LIBFFI_LIBS := $(shell pkg-config --libs-only-L libffi 2>/dev/null) + ifneq ($(LIBFFI_CFLAGS),) + CFLAGS += $(LIBFFI_CFLAGS) + LDFLAGS_LIBFFI = $(LIBFFI_LIBS) + endif + LDFLAGS_OPENSSL = + LDFLAGS_LIBWEBSOCKETS = + HAS_LIBWEBSOCKETS := 0 + # Windows base libraries (no -ldl, add -lws2_32 for Winsock) + LDFLAGS_BASE = -lm -lpthread -lffi -lz -lcrypto -lws2_32 + else # On Linux, use pkg-config if available LIBFFI_CFLAGS := $(shell pkg-config --cflags libffi 2>/dev/null) @@ -48,10 +76,12 @@ else # Check if libwebsockets is available on Linux HAS_LIBWEBSOCKETS := $(shell pkg-config --exists libwebsockets 2>/dev/null && echo 1 || (test -f /usr/include/libwebsockets.h && echo 1 || echo 0)) + # Linux base libraries + LDFLAGS_BASE = -lm -lpthread -lffi -ldl -lz -lcrypto endif -# Base libraries (always required) -LDFLAGS = $(LDFLAGS_LIBFFI) $(LDFLAGS_OPENSSL) -lm -lpthread -lffi -ldl -lz -lcrypto $(EXTRA_LDFLAGS) +# Combine LDFLAGS +LDFLAGS = $(LDFLAGS_LIBFFI) $(LDFLAGS_OPENSSL) $(LDFLAGS_BASE) $(EXTRA_LDFLAGS) # Conditionally add libwebsockets ifeq ($(HAS_LIBWEBSOCKETS),1) diff --git a/docs/WINDOWS_SUPPORT.md b/docs/WINDOWS_SUPPORT.md new file mode 100644 index 00000000..46ba2289 --- /dev/null +++ b/docs/WINDOWS_SUPPORT.md @@ -0,0 +1,184 @@ +# Windows Support for Hemlock + +This document describes Windows support for the Hemlock programming language. + +## Overview + +Hemlock now includes experimental Windows support via MinGW-w64.
