compile("memset_shim") produces libmemset_shim.a, not memset_shim.o, so the
previous cargo:rustc-link-arg pointed at a file that never exists. Switching to
get_compiler().to_command() compiles memset_s_shim.c directly to a .o file at
a known OUT_DIR path and passes it as a positional linker arg. A positional .o
is always included unconditionally, which also resolves the archive-extraction
ordering issue where -l flags only pull symbols that are already undefined at
that point in the link command.
- Use rustc-link-arg to directly link memset_shim.o object file
instead of -l flag, ensuring symbol is available regardless of
link order with libsodium_sys
- Add #[allow(dead_code)] to find_ollama_binary() which is only
used inside cfg(target_os = "macos") and cfg(target_os = "linux")
blocks, causing false positive warning when cross-compiling for Windows
- Add __MINGW32__ detection in memset_s_shim.c for proper EXPORT macro
- Add WIN32 and __WIN32__ defines when compiling the shim in build.rs
- The memset_explicit symbol is required by libsodium-sys-stable but not
available in MinGW runtime
- The shim is compiled as a static library and linked before libsodium
- Add __declspec(dllexport) to memset_explicit in memset_s_shim.c
- Explicitly link memset_shim library in build.rs for Windows MinGW target
- Fixes undefined reference to memset_explicit when building for x86_64-pc-windows-gnu
libsodium-sys requires memset_explicit which is not available in older
MinGW toolchains. Added a C shim that provides a fallback implementation
using volatile pointers to prevent compiler optimization.
Changes:
- Added memset_s_shim.c with fallback memset_explicit implementation
- Updated build.rs to compile shim for Windows GNU targets
- Added cc crate as build dependency
- Set CFLAGS in CI to target Windows 8+ (_WIN32_WINNT=0x0602)
- Set SODIUM_STATIC=yes to force static libsodium build
Fixes linking error: undefined reference to memset_explicit
