- Apply #undef bind patch to both llvmjit_inline.cpp and llvmjit_wrap.cpp - Place the patch right after postgres.h include to catch the bind macro early - This should resolve the std::bind vs pgwin32_bind macro conflict 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Add C++ standard library linking: -lstdc++ -lgcc_s -lwinpthread - Patch both src/Makefile.shlib and LLVM JIT Makefile for Windows - Add missing PostgreSQL symbol exports to postgres.def file - Target all the undefined reference errors we saw in linking - If this doesn't work, at least we'll get better error messages\! 🎲 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Make SHLIB_LINK pattern more precise to avoid false matches - Only target actual SHLIB_LINK variable assignments - Add safety check for LLVM Makefile before patching - Previous pattern was too greedy and corrupted library names 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
AGGRESSIVE MULTI-ANGLE ATTACK on Windows LLVM linking: 1. Patch main Makefile.shlib with C++ libs 2. Patch LLVM Makefile + add LIBS and CPPFLAGS 3. Patch configure script for global Windows C++ flags 4. Force C++ linker (g++) instead of gcc for LLVM 5. Add C++ libs to main postgres backend Makefile 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
MULTI-STRATEGY SYMBOL EXPORT APPROACH: 1. Find and patch any existing .def files 2. Create postgres.def with EXPORTS section if missing 3. Force --export-all-symbols for main postgres executable 4. Add explicit export flags with import library generation 5. Patch postgres Makefile to use .def file Target all missing PostgreSQL symbols for LLVM JIT DLL linking. We're at the final hurdle - C++ linking is solved\! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Replace --def= with direct .def file reference for MinGW linker - MinGW ld doesn't recognize --def= option, needs direct file path - We're at the finish line - export flags are working\! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
MAJOR CLEANUP - The civilized approach: - Use Meson build system for all full variants instead of autotools - Meson has native LLVM support and cross-compilation capabilities - Add Windows MinGW64 cross-compilation file for proper toolchain setup - Install Meson, Ninja, and pkg-config in MSYS2 environment - Keep autotools for lite variants (simpler, proven to work) - Remove all sed-based patches and linking hacks Meson configuration: - -Dllvm=enabled for proper LLVM JIT support - Proper MinGW cross-compilation with toolchain file - Native dependency detection instead of manual patching This should solve Windows LLVM compilation issues properly\! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

- Change path from ../windows-mingw64.txt to ../../windows-mingw64.txt - Account for being in build/postgresql-17.5/ directory - Cross-file is in project root, need to go up two levels 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Use full /mingw64/bin/ paths for all toolchain binaries - Fix deprecated pkgconfig -> pkg-config - Ensure Meson can find x86_64-w64-mingw32-ar and other tools - Should resolve "Unknown linker" and "file not found" errors 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Remove --cross-file parameter, let Meson auto-detect MSYS2 environment - MSYS2 bash shell should provide native MinGW toolchain access - Simplified cross-file for future reference if needed - May work better as native build within MSYS2 environment 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…ixes - Meson is working perfectly\! Just need to fix the bind macro conflict - Add targeted sed patches only for the specific C++ compilation issues - Fix bind macro in llvmjit_wrap.cpp and llvmjit_inline.cpp - Fix rindex usage in llvmjit.c - Keep patches minimal since Meson handles the heavy lifting We're so close\! Meson eliminated all the linking complexity. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Added Windows-specific header replacement to handle POSIX sys/mman.h not being available on Windows.
