The root issue is in the nalgebra
crate and it's something that was fixed between nalgebra 0.16.0
and nalgebra 0.16.1
.
EDIT: nalgebra 0.16.1
removed use serde;
imports, almost certainly as a response to this regression.
The ipfs-api
crate does not use nlagebra
at all. All of these build logs seem to have something wrong with serde
involved; for example, ipfs-api
gets a lot of errors associated with its use of #[serde(rename_all = "PascalCase")]
, along the lines of:
Sep 21 17:09:54.166 INFO kablam! error: cannot determine resolution for the attribute macro `serde`
Sep 21 17:09:54.166 INFO kablam! --> /cargo-home/registry/src/github.com-1ecc6299db9ec823/nalgebra-0.15.3/src/linalg/symmetric_tridiagonal.rs:16:5

Sep 21 17:09:54.166 INFO kablam! |
Sep 21 17:09:54.166 INFO kablam! = note: import resolution is stuck, try simplifying macro imports
All the other build logs appear to have "undefined type or module" along with the error import resolution is stuck, try simplifying macro imports
. Removing the serde
annotations from ipfs-api
lets it build successfully, though the protocol it speaks is then incorrect.
Yes, ipfs-api
is a separate case (probably with the same underlying issue in rustc) and it's already tracked separately in https://github.com/rust-lang/rust/issues/54386, the other regressed crates use nalgebra
.
Aha, thanks!
Minimized:
#![allow(unused)]
#[macro_use]
extern crate serde_derive;
use self::one::*;
use self::two::*;
mod serde {}
mod one {
use serde;
#[derive(Serialize)]
#[serde]
struct One;
}
mod two {
use serde;
#[derive(Serialize)]
#[serde]
struct Two;
}
fn main() {}
Fixed in https://github.com/rust-lang/rust/pull/54518 All the crates listed in https://github.com/rust-lang/rust/issues/54471#issue-362858527 build successfully now.
