[Windows]: Cannot open linker script file linkall.x due to umlauts in project path #124

Closed oleid closed 10 months ago

oleid commented 10 months ago

Dear all,

I'm trying to build a hello world project derived from this template on Windows 10 in a MSVC environment. It was set up the following way:

  1. Install rustup-msvc via scoop
  2. Install microsoft command line compiler (like the scoop package suggested)
  3. Install nightly rust via rustup
  4. Install espup and cargo-generate via cargo
  5. Run espup install according to documentation

After that I generated the project for esp32 via this git repo

cargo build compiles everything but linking fails with:

EDIT: It would appear that there is a linkall.x in cargo's crate registry below esp32-hal-0.16.0/ld/. But that folder is not among the linker search directories.

Any idea what might be wrong here or any pointers how to debug this?

Thanks a lot, Olaf

I would recommend trying to install Rust from the official website, as using package managers sometimes gives some troubles. If you are targeting an esp32, which is Xtensa based, you don't need nightly toolchain. See https://esp-rs.github.io/book/installation/riscv-and-xtensa.html

Okay, I tried that. I

Ah, I got it! Once I realized that the linker script got copied by esp32-hal's build script to the target out folder, I noticed that folder containing the rust project included an umlaut! Apparently gcc somehow doesn't like a path containing umlauts on windows (doh!).

It might be possible that this is an windows powershell encoding issue like here: https://www.reddit.com/r/rust/comments/we4y3p/why_utf8_characters_get_broken_when_piped_in/

I think I'm going back to Linux ;)

So should we document somewhere?

Oh! Glad you found the issue, thanks for sharing the solution, just updated the title so any users that looks for the error can check the solution! Thanks again for the feedback!
