IDF v5.0 build errors from fresh template project in Windows 10 - could not find `http` in `embedded_svc`

[gak]

I set up a fresh project from esp-idf-template and am getting errors on the first attempt. I'm not sure what I'm doing wrong here.

I've tried reinstalling the esp rust toolchain (nuking the directory and reinstalling).

Windows 10

I've de-duplicated some of the errors:

[ivmarkov]

Can you please move this bug report to esp-idf-template? The bug is there. Basically, you need to explicitly depend on embedded-svc and put a patch of embedded-svc in the [patch-crates.io] section.

• Or wait until we release new versions of all esp-idf-* crates (should be this weekend)
• Or use ESP IDF v4.4

[ivmarkov]

If you re-generate your project, it should work fine now, incl. for ESP IDF >= 5.

Amazing! Thank you.
