cargo test fails - linker issues

[yycdevelops]

Seeing:

note: rust-lld: error: undefined symbol: ngx_palloc
rust-lld: error: undefined symbol: ngx_pool_cleanup_add
rust-lld: error: undefined symbol: ngx_array_push

when running cargo test. cargo build works fine. This is happening for me even on the curl.rs example. Using vendored

Am I missing something or is this an issue?

Thank you for this report. This is a known issue and there is PR #204 with suggested fix. There were some offline suggestions for this PR and I'm planning to make necessary corrections.

@ensh63 what's the status of your work? Right now, I can't even get this to compile at all with even just cargo build on macOS at least, and I'm wondering if that's related:

ld: symbol(s) not found for architecture arm64

that is with

nginx-src = "1.28.4"
ngx = { git = "https://github.com/nginx/ngx-rust.git", features = ["vendored"] }

(excuse me if this is completely unrelated, I can file a new bug)

That is a different issue. On macOS you have to add linker flags via build.rs:

ngx-rust/build.rs

Lines 62 to 67 in 3b07964

	// Generate required compiler flags
	if cfg!(target_os = "macos") {
	// https://stackoverflow.com/questions/28124221/error-linking-with-cc-failed-exit-code-1
	println!("cargo::rustc-link-arg=-undefined");
	println!("cargo::rustc-link-arg=dynamic_lookup");
	}

Whoops, I'm so sorry, I missed that. I'll mark my comments as off-topic. Thanks for the hint!

Is there a workaround until this PR is merged for this issue?
