MacOS giving Undefined symbols for architecture x86_64

[danielkwinsor]

When using set_http_request_header on a MacOS, I get linker errors

  = note: Undefined symbols for architecture x86_64:

                proxy_wasm::hostcalls::set_map_value::hc96c1a7a99f6f34a in libproxy_wasm-e355260dbc0dec8a.rlib(proxy_wasm-e355260dbc0dec8a.proxy_wasm.9pm5zsy4-cgu.1.rcgu.o)

          clang: error: linker command failed with exit code 1 (use -v to see invocation)

Here's a testbed I was using to play around with

use proxy_wasm::traits::*;
use proxy_wasm::types::*;

struct MyFilter {
}

pub trait MyTrait {
    fn set_http_request_header(&self, name: &str, value: Option<&str>) {
    }
    fn on_http_request_headers(&mut self, _: usize) -> Action {
        Action::Continue
    }
}

impl MyFilter {
    fn add_token_to_headers(&mut self, token: Option<&str>) {
        proxy_wasm::traits::HttpContext::set_http_request_header(self, "header_name", Some("token"));
        //try proxy_wasm::traits::HttpContext:: or MyTrait::
    }
}

impl MyTrait for MyFilter {
    fn on_http_request_headers(&mut self, _: usize) -> Action {
        self.add_token_to_headers(Some("token"));
        //self.set_http_request_header("header_name", Some("token"));
        Action::Continue
    }
}

impl Context for MyFilter { }

impl HttpContext for MyFilter {
    fn on_http_request_headers(&mut self, _: usize) -> Action {
        self.add_token_to_headers(Some("token"));
        //self.set_http_request_header("header_name", Some("token"));
        Action::Continue
    }
}

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_linkage() {
        let mut filter = MyFilter {
        };
        
        //filter.add_token_to_headers(Some("token"));
        proxy_wasm::traits::HttpContext::on_http_request_headers(&mut filter, usize::from_str_radix("A", 16).ok().unwrap());
        //try proxy_wasm::traits::HttpContext:: or MyTrait::
    }
}

Have you find a solution for this?

You need to be building for wasm32-wasip1 (or wasm32-unknown-unknown) target, i.e.

cargo build --target wasm32-wasip1 --release

(as described in README in all of the examples)
