Linker error when building for ESP32-S2

[ryanc-me]

hello! i'm getting a linker error when building for the ESP32-S2 variant.

the error is very similar to #24, except it's complaining about undefined reference to '__sync_lock_test_and_set_4'

full error:

error: linking with `ldproxy` failed: exit status: 1

error: could not compile `rust-esp32-std-demo` due to previous error

and, in case this is helpful:

• this is all installed in an Ubuntu 20.04 podman container
• installed esp-idf via https://docs.espressif.com/projects/esp-idf/en/latest/esp32/
• installed esp-rs/rust via https://github.com/esp-rs/rust-build
• trying to build the vanilla version of this project - no changes

for what it's worth, i'm getting the same error when using cargo build on the espressif/idf-rust-examples docker image also (which, again, is using Ubuntu 20.04 as a base). maybe some library is missing in the minimal Ubuntu docker base?

thanks!

As strange as it sounds, it is a dupe of #45, which I'm about to fix soon (certain patches that have to be applied to ESP-IDF 3.4.1 are actually not applied; one of these is support for S2 atomics that brings this function that you see the linker complaining about).

[ryanc-me]

thanks Ivan! I did see your work & PRs over at ESP-IDF.

for what it's worth, the esp-idf-template does work, if you choose to install ESP-IDF master branch. I guess your fixes are included in master. I couldn't get rust-esp32-std-demo working though, even if I uncommented ESP_IDF_VERSION = { value = "master" } in the Cargo config.

isw there another way I can force embuild to install ESP-IDF from master?

thanks Ivan! I did see your work & PRs over at ESP-IDF.

for what it's worth, the esp-idf-template does work, if you choose to install ESP-IDF master branch.

But even then you have to build with cargo build --features native. See below.

I guess your fixes are included in master.

No. The fixes are related to how you build the thing. If you use the default pio builder (as in cargo build --features pio or cargo build), then you are affected because the PlatformIO builder is used, and that one cannot apply the patches which are necessary for V4.3.1 (the only branch supported by PlatformIO).

I couldn't get rust-esp32-std-demo working though, even if I uncommented ESP_IDF_VERSION = { value = "master" } in the Cargo config.

Read this. ESP_IDF_VERSION is only honored by the non-default native builder (cargo build --features native).

isw there another way I can force embuild to install ESP-IDF from master?

See above. Branches other than v4.3.1 are only supported by the native builder.

[ryanc-me]

Right, that makes sense! I've done a bit more reading and am more up to speed now. Sorry to bother you with simple questions.

For what it's worth though, esp-idf-template was working without the --features native flag. Maybe it was an envvar or cached crate. But anyway, this project is compiling nicely using the native builder and ESP-IDF master branch. Thanks!
