note: zig translate-c can't translate complicated macros well enough.

For tests, try use:

https://github.com/kassane/zig-esp-idf-sample

  • custom panic handler (w/ esp_system_abort)
  • custom logging (w/ esp_writer_log)
  • custom Zig (C wrapper) allocators (multi_heap & heap_caps)
  • freertos tasks
  • led-strip & gpio

to fix: add -fno-compiler-rt flag.

Recently, making zig a static library instead of an executable, I tested zig-extensa with esp-idf without any problems.

Regarding an executable, I haven't solved the floating point (fp) problem during casting yet. But based on another user's hint (using esp-rs), I could try to build a standalone executable by replacing compiler-rt by libgcc + crt*.o for the esp32-s3 target.

I'll add mini documentation about zig on Xtensa:
