M1 toolchain setup

[adrien3d]

On my M1 Mac, since I was unable to compile my project, having the following error:

error: failed to run custom build command for esp-idf-sys v0.35.0

Using activated esp-idf v5.2.2 environment at '/Users/adrien/Dev/esp/esp-idf'
CMake Error at /Users/adrien/Dev/esp/esp-idf/tools/cmake/tool_version_check.cmake:36 (message):

Tool doesn't match supported version from list ['esp-13.2.0_20230928']:
/Users/adrien/.rustup/toolchains/esp/riscv32-esp-elf/esp-12.2.0_20230208/riscv32-esp-elf/bin/riscv32-esp-elf-gcc

I then launched an espup install and then an espup update

Now I have this error:

error: "/Users/adrien/.rustup/toolchains/nightly-x86_64-apple-darwin/lib/rustlib/src/rust/Cargo.lock" does not exist, unable to build with the standard library, try:
rustup component add rust-src --toolchain nightly-x86_64-apple-darwin

I launched the recommended command, but I still have the same error (with and without launching the export-esp.sh script that have the following content:

export PATH="/Users/adrien/.rustup/toolchains/esp/xtensa-esp-elf/esp-13.2.0_20230928/xtensa-esp-elf/bin:$PATH"
export LIBCLANG_PATH="/Users/adrien/.rustup/toolchains/esp/xtensa-esp32-elf-clang/esp-17.0.1_20240419/esp-clang/lib"

Hi! What chip are you targeting? espup can install the environment for RISC-V targets, but is not needed. I would recommend doing the following:

• Install the RISC-V toolchain: either via espup or rustup. See https://docs.esp-rs.org/book/installation/riscv.html
• Do not use an activated environment at start, let esp-idf-sys download the correct esp-idf that your project is configured to use.
  • Not sure what project are you trying to build, but you might have the wrong esp-idf version activated.

Not sure if you already did, but I recommend reading https://docs.esp-rs.org/book/installation/index.html

[adrien3d]

I am targeting a C6.
I've tried what you recommended, but I still have the same error.
My project is open-source: https://github.com/adrien3d/iss/blob/feat/ntp%26config/Cargo.toml
But basically, all latest commits on each branch (master, feat/ntp & feat/ntp&config) are not compiling on both my Mac and an Ubuntu computer, giving always the same error.

May be the issue is in the rust-toolchain.toml that is a nightly one, and not a nightly fixed at a specific day?

[SergioGasquez]

Just tried with my M1, and I was able to successfully build your project master branch. I assume you have already nightly channel installed, either by espup or by rustup toolchain install nightly --component rust-src

May be the issue is in the rust-toolchain.toml that is a nightly one, and not a nightly fixed at a specific day?

That should not be the issue. By the way, you could also use stable now.

Can you share the error? Please, make sure that you don't have any ESP-IDF activated.

[adrien3d]

Yep, same as above.
When I build using nightly, I have:

error: "/home/achapelet/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/Cargo.lock" does not exist, unable to build with the standard library, try:
rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu

When I build using stable, I have:

Compiling autocfg v1.3.0
error[E0463]: can't find crate for core

= note: the riscv32imac-esp-espidf target may not be installed
= help: consider downloading the target with rustup target add riscv32imac-esp-espidf

For more information about this error, try rustc --explain E0463.
error: could not compile nb (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...

and then:

rustup target add riscv32imac-esp-espidf
error: toolchain 'stable-x86_64-unknown-linux-gnu' does not support target 'riscv32imac-esp-espidf'
note: you can see a list of supported targets with rustc --print=target-list
note: if you are adding support for a new target to rustc itself, see https://rustc-dev-guide.rust-lang.org/building/new-target.html

[SergioGasquez]

But if you run rustup component add rust-src --toolchain nightly-x86_64-unknown-linux-gnu you get any errors?

[adrien3d]

No, just info: component 'rust-src' is up to date, same on my mac :(

[SergioGasquez]

Did you installed Rust using any package manager? I would recommend uninstalling your Rust and installing it again with:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup toolchain install nightly --component rust-src

[adrien3d]

It was already installed with rustup but I reinstalled it as you asked. Now when doing a build I have:

   Compiling esp-idf-sys v0.35.0
The following warnings were emitted during compilation:

[SergioGasquez]

Seems like you are using an activated ESP-IDF environment custom esp-idf repository detected via $IDF_PATH, please unset IDF_PATH and let esp-idf-sys download it

[adrien3d]

Now fixed with what you asked, thank you very much for your reactive support.
