## Compiling on Windows with MSYS2 (32-bit) ## Compiling on Windows with MSYS2 (32-bit)
Follow these steps to build `BlockLua.dll` for 32-bit Windows using MSYS2's MinGW-w64 i686 toolchain. Follow these steps to build `BlockLua.dll` for 32-bit Windows using MSYS2's MinGW-w64 i686 toolchain.
### 1) Install MSYS2 ### 1) Install MSYS2

- Compiles the project with `-m32` and links against `lua5.1`. - Compiles the project with `-m32` and links against `lua5.1`.
- Produces `build\BlockLua.dll` and `build\BlockLua-Unsafe.dll`. - Produces `build\BlockLua.dll` and `build\BlockLua-Unsafe.dll`.
### 4) Optional: Verify 32-bit output ### 4) Optional: Verify 32-bit output
If you installed binutils, you can check the architecture: If you installed binutils, you can check the architecture:
```powershell ```powershell
objdump -f build\BlockLua.dll | Select-String i386 objdump -f build\BlockLua.dll | Select-String i386
``` ```
You should see `architecture: i386` in the output. You should see `architecture: i386` in the output.
### Notes ### Notes
- Ensure you installed the i686 (32-bit) variants of the packages; x86_64 packages won’t work for a 32-bit build. - Ensure you installed the i686 (32-bit) variants of the packages; x86_64 packages won’t work for a 32-bit build.
- If the linker cannot find `-llua5.1`, confirm `mingw-w64-i686-lua51` is installed and you are using the `mingw32` toolchain (not `x86_64`). - If the linker cannot find `-llua5.1`, confirm `mingw-w64-i686-lua51` is installed and you are using the `mingw32` toolchain (not `x86_64`).
