extendr: doctest fails on Windows with "LINK : fatal error LNK1181: cannot open input file 'R.lib'" when proc_macro = true
(From https://github.com/extendr/extendr/pull/347#issuecomment-1030119516)
Here’s the minimal reproducible example. Note that, if I change proc_macro
to false
, no error happens.
Cargo.toml
[package]
name = "foo"
version = "0.1.0"
edition = "2021"
[lib]
proc_macro = true
[dependencies]
[dev-dependencies]
extendr-api = { path = "../extendr-api" }
src/lib.rs
/// ```
/// use extendr_api::prelude::*;
/// ```
fn foo() {}
command
cargo test --manifest-path foo/Cargo.toml --target=x86_64-pc-windows-gnu --doc -- --nocapture

I agree that we should keep extendr-macros lightweight. The only reason we have extendr-macros is that the system of the crate requires us to do so; it’s never intended to be used solely. So, if a test needs extendr-api, it should be moved to extendr-api.
