Linking regression with esp-idf based build and Rust 1.89

[tronical]

Code

Unfortunately, I don't have a small code snippet, but the following steps reproduce the link error below (on my machine on macOS, but also in our CI on Linux):

. ~/esp/esp-idf/export.sh
git clone https://github.com/slint-ui/slint
cd slint/demos/printerdemo_mcu/esp-idf/
idf.py build

This used to compile and link just fine. For example with espup install -v 1.88. But with espup install -v 1.89 as well as espup install -v 1.90 the following error happens at link time:

Perhaps I should add this clarification: what looks like an esp-idf project builds Rust code underneath and links the resulting .a file in the esp-idf project.

[MabezDev]

Looks to me like a conflict of using esp-println with esp-idf (see the warning about orphan sections in your post and https://github.com/esp-rs/esp-hal/blob/d4330d3126f69b8c22a94640450b6542c7e36c65/esp-println/src/lib.rs#L13-L29).

Try removing esp-println, you don't need it, this is a std project anyways, right?

[tronical]

Wow, I would've never discovered this. It's true, esp-println triggers this, and we don't strictly need esp-println, but we're using esp/backtrace and we're building the library with no_std (and -Zbuild-std=core,alloc). It's really helpful to get backtraces when something goes wrong (in a panic), but also logging output is very convenient.

Should I bring this to the esp-hal/esp-println repo? Or is it clear that this isn't going to be supported in the future?

[MabezDev]

You should be able to get this to work if you add a linker script (or modify an existing one) to include this section: https://github.com/esp-rs/esp-hal/blob/190e29967fe200e86315ae2890f6ba162e8767f8/esp-hal/ld/sections/metadata.x#L2-L5.

[MabezDev]

Closing as it's not a toolchain issue, but I think with the comments above you can get this working again :).

[tronical]

Thank you very much for your help. I agree, this doesn’t look like a toolchain issue.

[stevehayles]

For anyone struggling with the issue I can confirm the approach from the comments above has worked in my case.

I added a linker-fix.ld file with exactly these contents

SECTIONS {
  .espressif.metadata 0 (INFO) :
  {
    KEEP(*(.espressif.metadata));
  }
}

and then added the following (which could be simplified) to the end of my build.rs file

// locate the linker-fix.ld script
let script_dir = std::env::var("CARGO_MANIFEST_DIR").unwrap();
println!("cargo:rerun-if-changed=linker-fix.ld");

// Add the linker script to the linker's search path and specify it as a linker argument
println!("cargo:rustc-link-search={}", script_dir);
println!("cargo:rustc-link-arg=-Tlinker-fix.ld");
