8cc VS rust

The compiler looks to be here: https://github.com/rui314/8cc

Implement a compiler for a subset of C. This doesn't need to be self-hosting, but bonus points if it is. Here's an example of what it can look like: https://github.com/rui314/8cc

While this is an impressive work, I feel that there are a lot of "tiny" C compilers out there; how is yours any different than SmallerC, TinyC, 8cc, chibicc and many others?

See https://github.com/rui314/8cc https://github.com/rswier/c4 for a demonstration of this.

The esp-template issue might be this one: https://github.com/esp-rs/rust/issues/158. Try with --release or updating to 1.68.0 with espup update. I'll take a look at the log as soon as I can, atm Im on the phone and is not that easy to scroll through :(

Sure. Espressif maintains a fork which adds support for their microcontrollers.

I am trying to make a vaccine passport validation for my country using the ESP32 for my micro controller. I have gotten the std rust library to compile using (esp-rs)[https://github.com/esp-rs/rust], but the actual validation library that I use needs openssl which refuses to compile.

Xtensa. They've got a fork of LLVM that supports it that they're working toward getting upstreamed. The community has a fork of rustc that uses it (and a quickstart crate) while we wait for it to get upstreamed.

It only works if you have an Xtensa compiler which takes hours to compile, here: Rust Xtensa (if you don't have it). The network driver is just a function that sets the name of the driver so the Esp32 does something other that blinking.
