cargo-xwin drives the Windows MSVC cross-compile via clang-cl, under which CMake sets MSVC=1 — causing libopus 1.3.1's `if(NOT MSVC)` guards to skip the per-file `-msse4.1` / `-mssse3` COMPILE_FLAGS that its x86 SIMD source files need. Clang-cl (unlike real cl.exe) still honors Clang's target-feature system, so those files then fail to compile with "always_inline function '_mm_cvtepi16_epi32' requires target feature 'sse4.1'" errors across silk/NSQ_sse4_1.c, NSQ_del_dec_sse4_1.c, and VQ_WMat_EC_sse4_1.c. Earlier attempts to fix this downstream (cargo-xwin toolchain file, override.cmake CMAKE_C_COMPILE_OBJECT <FLAGS> replace, CFLAGS env vars) all failed because cargo-xwin rewrites override.cmake from scratch on every `cargo xwin build` invocation and cmake-rs's -DCMAKE_C_FLAGS= assembly happens before toolchain FORCE sets propagate. Fixing it upstream at the source: vendor audiopus_sys 0.2.2 into vendor/audiopus_sys, patch its bundled opus/CMakeLists.txt to introduce an MSVC_CL var (true only when CMAKE_C_COMPILER_ID == "MSVC", i.e. real cl.exe), and flip the eight `if(NOT MSVC)` SIMD guards to `if(NOT MSVC_CL)`. Clang-cl then gets the GCC-style per-file flags and the SSE4.1 sources build cleanly. Also flip the `if(MSVC)` global /arch block at line 445 to `if(MSVC_CL)` so only cl.exe applies /arch:AVX and clang-cl relies purely on per-file flags (no global/per-file mixing). Wire via [patch.crates-io] in the workspace root Cargo.toml; the patch is resolved relative to the workspace root as `vendor/audiopus_sys`. Upstream context: xiph/opus#256, xiph/opus PR #257 (both stale). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

|
|
* Updated `bindgen` to version `0.58`.
|
|
|
|
## [0.1.8]
|
|
|
|
This release adds build support for FreeBSD.
|
|
|
|
## [0.1.7]
|
|
|
|
Add missing `opus`-folder.
|
|
|
|
## [0.1.6]
|
|
|

This release removes the `bindgen`-dependency from the default features.
|
|
Additionally, the `bindgen`-feature has been added in order to generate a new binding.
|
|
|
|
## [0.1.4 and 0.1.5]
|
|
|
|
v0.1.4:
|
|
This release fixes a problem where `audiopus_sys` could not find the
|
|
Opus folder.
|
|
|
|
v0.1.5:
|
|
Convert Unix-relevant files' EOLs from CRLF to LF inside the opus-folder.
|
|
|
|
### **Fix**
|
|
* Bundle the Opus project again.
|
|
* Added missing `cfg` on `find_via_pkg_config`.
|
|
|
|
## [0.1.3]
|
|
|
|
Fixes build-issues related to `pkg-config`.
|
|
|
|
## [0.1.2]
|
|
|
|
This release adds the ability to bypass `pkg-config`.
|
|
|
|
### **Added:**
|
|
|
|
* Ignore `pkg-config` when `LIBOPUS_NO_PKG` or `OPUS_NO_PKG` is set.
|
|
* Print the dynamic/static build cause via `cargo:info`.
|
|
* Add missing repository-link in `Cargo.toml`.
|
|
|
|
## [0.1.1]
|
|
|
|
### **Added:**
|
|
|
|
* Copy Opus' source to `OUT_DIR` before building to avoid modifying and generating files outside of `OUT_DIR`.
|
|
|
|
### **Fixed:**
|
|
* Convert Unix-relevant files' EOLs from `CRLF` to `LF` inside the `opus`-folder.
|
|
* Resolve unused import warnings when building with Unix.
