Rust for esp32 error: `-Csplit-debuginfo` is unstable on this platform

Postby libao_o@qq.com » Sun Aug 14, 2022 3:09 am

我按照安装教程在Ubuntu上安装了Rust for ESP32 环境,使用ESP32 模板建立了一个项目,但是在编译是出现以下错误;
我又尝试在win10上按教程安装了Rust for esp32环境,也出现了同样的错误。

I installed rust for esp32 environment on Ubuntu according to the installation tutorial and created a project using the esp32 template. However, the following errors occurred during compilation: failed to run custom build command for `esp-idf-sys v0.31.7`
I tried to install rust for esp32 environment on win10 according to the tutorial, and the same error occurred.

Hi there, do you know what is passing the `-Csplit-debuginfo` flag? As far as I know, we do not pass this command anywhere in the examples. I believe this flag is only stable on MacOS, not Windows or Linux, judging by this thread: https://github.com/rust-lang/rust/issues/34651. Is it possible your IDE is passing this flag?

Could you try generating a fresh project from the template repo https://github.com/esp-rs/esp-idf-template and see if you can build and flash that?
