Build errors in esp-idf-svc when adding ESP IDF components in a mixed C++ / Rust project. #263
Description
Hello, thansk for this project!
I have a mixed project C++ / Rust because I would like to use the FastLED library as a component. Everything compiled and worked very well when doing the tests with only FastLED.
However I wanted to extend the project and use MQTT and the ethernet port on my EPS board. But when adding the necessary components in the CMakeList file, I encounter errors when building the esp-idf-svc crate (no external crate esp_sntp_init, cannot find struct ip_addr_t, etc).
I am quite probably doing a silly error but I cannot find where. What I did :
- doing a idf.py fullclean,
- doing a idf.py set-target esp32
- running again idf.py menuconfig to enable the FreeRTOS backward compatibility I need for FastLED.
- cleaning any build cache.
- idf.py build -> the process stops when compiling the rust dependencies, at the esp-idf-svc crate.
I also tested creating a blank new project :
- cargo generate --vcs none --git https://github.com/esp-rs/esp-idf-template cmake
- modifying the components/rust-esp32_test/CMakeList.txt RUST_DEPS : set(RUST_DEPS "pthread" "driver" "vfs" "esp_eth" "esp_netif" "esp_event" "mqtt")
- idf.py set-target esp32
- idf.py build
I have the same errors. There are 77 errors all related to crates or structs or functions not found, I can post a list if needed.
My ESP IDF version is 5.2 (I tried also 5.1 without success).
Sorry if I missed something in the readme files.
