LoadLibraryExW failes on libclang.dll

[FssAy]

When trying to run cargo build on Windows 10 after performing every step from the book I am getting an error:

Unable to find libclang: "the `libclang` shared library at C:\\Users\\Dmitrij\\.rustup\\toolchains\\esp\\xtensa-esp32-elf-clang\\esp-clang\\bin\\libclang.dll could not be opened: LoadLibraryExW failed"

The path to the file is correct, the file exists and is not corrupted.

Here is the full log:

I have all dependencies installed and using the unmodified generated template with correct options on the correct board (ESP32-S3).

Does anyone have any ideas? I am stuck.

Hi!

Have you checked that C:\\Users\\Dmitrij\\.rustup\\toolchains\\esp\\xtensa-esp32-elf-clang\\esp-clang\\bin\\libclang.dll exists?? It should be there if the espup command succeeded, but just to verify.

Yes, it exists:

The path to the file is correct, the file exists and is not corrupted.

I traced back the issue to the bindgen crate. Especially the ensure_libclang_is_loaded function in lib.rs. It fails on

clang_sys::load().expect("Unable to find libclang");

But when I run this function manually in a dummy project it loads without any issues, so it's not a problem with my configuration or setup I guess. At this point I have no clue what is going on.

[FssAy]

Fixed by downgrading to a lower espup version.
