[rust/clang] failed to build rust program that uses certain static lib (.a) file

[zhguyu]

Description

Trying to build rav1e using recommended rust flags RUSTFLAGS="-C target-cpu=x86-64-v3" cargo build --release, and the thinLTO issue rust-lang/rust#98302 was circumvented by specifying fat LTO in Cargo.toml. Build failed with the following console output:

   Compiling rav1e v0.6.0 (F:\rav1e)
error: linking with `x86_64-w64-mingw32-clang` failed: exit code: 1

The file in fault mentioned in the output libwinapi_runtimeobject.a is a text file that has the following content:

INPUT(
libwinapi_runtimeobject-api-ms-win-core-winrt-error-l1-1-0.a
libwinapi_runtimeobject-api-ms-win-core-winrt-string-l1-1-0.a

)

I double checked that the last time I built the same program (rav1e) in 19 July was successful. After the initial attempt I also tried to build the exact same version (and even an older one) of rav1e as the last successful build in July and it was also a failure, with the same console output. Both clang and rust were updated in the past months so I don't know whose fault that is.

Verification

• I have verified that my MSYS2 is up-to-date before submitting the report (see https://www.msys2.org/docs/updating/)

Windows Version

Microsoft Windows [Version 10.0.22621.674]

MINGW environments affected

• MINGW64
• MINGW32
• UCRT64
• CLANG64
• CLANG32
• CLANGARM64

Expected behavior

Successful build.

Actual behavior

Build failed claiming an static lib (.a) file has unknown file type.

Repro steps

1. Clean installation of MSYS2
2. Update and install necessary packages such as clang (mingw-w64-clang-x86_64-toolchain) and rust
3. Grab the rav1e codebase from https://github.com/xiph/rav1e
4. Edit Cargo.toml profile to have the following content:

[profile.release]
opt-level = 3
strip = true
debug = false
incremental = false
lto = true

5. Build with RUSTFLAGS="-C target-cpu=x86-64-v3" cargo build --release

Unfortunately it's upstream issue that we cannot workaround in any way retep998/winapi-rs#935
You can workaround it locally though by defining WINAPI_NO_BUNDLED_LIBRARIES=1.
