Adding support for rust 1.78 to OpenSTLinux

[HSant.1]

Hello,
I'm a newbie using Yocto so my question maybe doesn't make a lot of sense.
I'm trying to add rust 1.78 to an existing image (STM32MP1 OpenSTLinux).

1. I cloned the repo in the layers directory (git clone https://github.com/meta-rust/meta-rust.git) .
2. I sourced my environment script (DISTRO=openstlinux-weston MACHINE=stm32mp15-disco IMAGE=st-image-weston source layers/meta-st/scripts/envsetup.sh)
3. I modified the file "layers/openembedded-core/meta/conf/distro/include/tcmode-default.inc" in order to change RUSTVERSION ?= "1.68%" to RUSTVERSION ?= "1.78%"
4. I run bitbake-layers add-layer meta-rust
5. I run bitbake-layers show-layers (my new layer is there : (rust-layer /home/hanoi/devel/STM32MP1/distribution-package/layers/meta-rust))
6. I compile the image (bitbake st-image-weston)
7. I can see the source files for rust-native-1.78.0-r0, cargo-native-1.78.0-r0 and rust-llvm-native-1.78.0-r0 are being fetched and unpacked

Now the problems:
compiling rust-native-1.78.0-r0

8. I "fixed" that editing /home/hanoi/devel/STM32MP1/distribution-package/build-openstlinuxweston-stm32mp15-disco/tmp-glibc/work/x86_64-linux/rust-native/1.78.0-r0/cargo_home/config

9. Start compiling again (bitbake st-image-weston)

10. after compiling some more packages I got this error compiling cargo-native and I don't know how to fix that

Can you help me compiling the image, or give a hint about it, or maybe there's another way completely different  ?
Thanks a lot !

Hello, Did you look at this article = https://wiki.st.com/stm32mpu/wiki/How_to_develop_a_Rust_Application

Recently ST added Rust SDK addons for x86 linux platform, could it help you to rapidly dev your own application ?
