error: failed to resolve imports (I think I'm doing something wrong)

[brendanzab]

I'm currently working on my linear algebra library, but I'm having trouble compiling it.

Here's the error I'm getting when I run $ make all

rustc src/om3d.rc --lib --out-dir=lib
error: failed to resolve imports
src/quat.rs:5:7: 5:14 error: unresolved import
src/quat.rs:5 import mat::*;
                     ^~~~~~~
src/mat.rs:5:7: 5:15 error: unresolved import
src/mat.rs:5 import quat::*;
                    ^~~~~~~~
src/projection.rs:2:7: 2:14 error: unresolved import
src/projection.rs:2 import mat::*;
                           ^~~~~~~
error: aborting due to 4 previous errors

My directory is layed out like so:

om3d-rs/
    | Makefile
    | src/
    |    | mat.rs
    |    | om3d.rc
    |    | projection.rs
    |    | quat.rs
    |    | vec.rs
    | ...

makefile

all:
    rustc src/om3d.rc --lib --out-dir=lib

src/om3d.rc

#[link(name = "om3d",
       vers = "0.1",
       author = "Brendan Zabarauskas")];

#[comment = "Linear algebra library for Rust. Incomplete and probably buggy."];
#[crate_type = "lib"];

use std;

mod mat;
mod projection;
mod quat;
mod vec;

src/quat.rs

// ...
import mat::*;
import vec::*;
// ...

src/mat.rs

// ...
import quat::*;
import vec::*;
// ...

src/projection.rs

// ...
import mat::*;
// ...

Any idea what am I doing wrong?

Ok, the issue was that the glob imports were triggering a cyclic import (see Issue #3352).

I fixed it by changing the imports:

src/mat.rs

// ...
import quat::quat;
import vec::*;
// ...

src/quat.rs

// ...
import mat::{mat3, mat4};
import vec::*;
// ...

src/projection.rs

// ...
import mat::{mat3, mat4};
// ...
