Installation on `x86_64-pc-windows-gnu`

[levimcgomes]

Looking at the releases page, I've found that x86_64-pc-windows-gnu binaries were available as far version 1.87, then suddenly stopped being distributed on later versions. I understand this probably isn't a very high demand target (although it is the only way to develop Rust software for ESPs on an MSYS2-based environment like the one I use) and maintaining it might not have been worth it. However, since espup tries to download the pre-built binaries from this repo's releases, I am unable to install the Xtensa toolchain for versions 1.88 or later - which are necessary for some of the ecosystem's crates' current versions.

Therefore, I'd like to know if there is a way to

• build the Rust binaries for x86_64-pc-windows-gnu locally; and
• have espup use those binaries instead of the pre-built ones (or just skip espup entirelly if that's possible, either way is fine for me).

Thanks in advance for any help.

Hello! Yes, x86_64-pc-windows-gnu support was dropped recently in rust-build, but you can build it locally following the instructions in https://github.com/esp-rs/rust?tab=readme-ov-file#building-from-source, and you can download GCC/LLVM, then you would need to udpate LIBCLANG_PATH and PATH environment variables, this way you won't require espup
