I have been trying to get this demo to work with different ESP_IDF_VERSIONs ('master', 'release/v4.4', 'release/v4.3.2') and different configurations in 'config.toml' but run into various issues as reported in earlier request. Would appreciate to get a step by step instruction on what to do so that the demo runs (for xtensa-esp32-espidf or xtensa-esp32s3-espidf). Something like:

rm -rf ~/.rustup/toolchains/esp
rm -rf ~/.espressif/
curl -LO https://github.com/esp-rs/rust-build/releases/download/v1.65.0.1/install-rust-toolchain.sh
chmod a+x install-rust-toolchain.sh
install-rust-toolchain.sh -s release/v4.4
unset CC
unset CXX
export LIBCLANG_PATH="~/.espressif/tools/xtensa-esp32-elf-clang/esp-15.0.0-20221014-x86_64-apple-darwin/esp-clang/lib/"
export IDF_TOOLS_PATH="~/.espressif"
. ./export-esp.sh
export IDF_PATH="~/.espressif/frameworks/esp-idf-release-v4.4"
cargo build

Are you following the build instructions? I specifically am at a loss why you are doing the following:

export IDF_TOOLS_PATH="~/.espressif"

And then also this:

export IDF_PATH="~/.espressif/frameworks/esp-idf-release-v4.4"

Also, what . ./export-esp.sh does is the same that you do here:

export LIBCLANG_PATH="~/.espressif/tools/xtensa-esp32-elf-clang/esp-15.0.0-20221014-x86_64-apple-darwin/esp-clang/lib/"
export IDF_TOOLS_PATH="~/.espressif"

so not sure why you are doing it twice, but I think at least this does not hurt.

Now, I'm on Linux, and I take it that the install-rust-toolchain.sh script might spit out something different for Mac OS, but if it did not spit out a request for you to define (IDF_TOOLS_PATH and IDF_PATH) please do not define them, or else I'm debugging your custom setup rather than vanilla rust-esp32-std-demo build. :)

For reference, on Linux install-rust-toolchain.sh asks me to put in my ~/.bashrc only these two variables, and this is what I do:

export LIBCLANG_PATH=...
export PATH=...

I opened a new CMD window to eliminate all issues with variables and it now compiles:

install-rust-toolchain.sh -s release/v4.4
. ./export-esp.sh
rustup default esp
unset CC
unset CXX
export RUST_ESP32_STD_DEMO_WIFI_SSID=[xxx]
export RUST_ESP32_STD_DEMO_WIFI_PASS=[xxx]
cargo build

Thanks again for your help.
