target `xtensa-esp8266-none-elf` does not support [bin] crate types

[zinahe]

Hi,

First of all, thanks for your hard work.

It seems the xtensa-esp8266-none-elf target somehow differs from the ESP32 in that I'm not able to build a bin with it; where as that build succeeds for xtensa-esp32-none-elf.

I am getting this error:

error: cannot produce bin for 'hello v0.1.0 (/path/to/project)' as the target 'xtensa-esp8266-none-elf' does not support these crate types

All the information I was able to find from the internet so far says there is a missing

"executables": true

somewhere in the source. Yes, I know I could just build a lib and link it with an empty app_main() in C. But I'm trying to do away with that if I can. I'm also using this as an opportunity to learn.

Grateful for any assistance,

Regards,

Zinahe A

Hi,

I dug some more and there is indeed a missing executables: true, in librustc_target/spec/xtensa_esp8266_none_elf.rs.

I'm not sure if simply adding it will fix my issue, but I'll give that a try and revert.

Just to report back. That fixed it for me. Hope someone finds this helpful.
