Hey,

I'm trying to get the example examples/wifi_embassy_dhcp.rs running in my own app. Unfortunately I struggle with the linking step. Maybe I miss something there. My setup:

My src/main.rs is exactly the wifi_embassy_dhcp.rs
Cargo.toml

[package]
name = "esp-modbus"
version = "0.1.0"
edition = "2021"

[dependencies]

esp-backtrace = { version = "0.14.2", features = ["esp32", "exception-handler", "panic-handler", "println"] }
esp-println = { version = "0.12.0", features = ["esp32", "log"] }
esp-wifi ={ version = "0.10.1", features = ["esp32", "async", "embassy-net", "wifi-default", "wifi", "utils"] }
static_cell = { version = "2.1.0", features = ["nightly"] }

esp-hal-embassy = { version =  "0.4.0", features = ["esp32"] }
embassy-executor = { version = "0.6.0", features = ["task-arena-size-12288"] }
embassy-net = { version = "0.4.0", features = [ "tcp", "udp", "dhcpv4", "medium-ethernet"] }
embassy-time = { version = "0.3.2", features = ["generic-queue-8"] }
embedded-io-async = "0.6.1"

Rust Version rustc 1.82.0-nightly (ffd10cecc 2024-10-25) (1.82.0.1)

All this compiles but fails in the linking step with the following error:

error: could not compile `esp-modbus` (bin "esp-modbus") due to 1 previous error

Note: Log is from Windows but it fails with the same Error on Ubuntu (via WSL).

If I checkout the esp-hal repo and build the examples/wifi_embassy_dhcp.rs inside the repo it works fine on both, Windows & Ubuntu (WSL)
