I have a patched version of a library. I am trying to use that library in an another application, however, imports are not correctly resolved.
[package]
name = "ndarray-mkl-issue"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
ndarray = { version = "0.14" }
ndarray-linalg = { git = "https://github.com/trickster/ndarray-linalg", rev = "df3c062dc3a9415838973a511261758fd1ac6add", features = [
"intel-mkl-system",
] }
With main.rs as:
use ndarray::*;
use ndarray_linalg::*;
fn main() {
let a: Array2<f64> = array![
[-1.01, 0.86, -4.60, 3.31, -4.81],
[3.98, 0.53, -7.04, 5.29, 3.55],
[3.30, 8.26, -3.89, 8.20, -1.51],
[4.43, 4.96, -7.66, -7.33, 6.18],
[7.31, -6.43, -6.16, 2.47, 5.58],
];
let (eigs, vecs) = a.eig().unwrap();
}
I get this error, even though Eig is already exported by the dependency. The patched dependency passes all tests.

I understand the reproducibility is an issue here. We need to download intel-mkl for it to work. On a linux intel machine.
wget https://registrationcenter-download.intel.com/akdlm/irc_nas/18483/l_onemkl_p_2022.0.2.136_offline.sh
sudo ./l_onemkl_p_2022.0.2.136_offline.sh -a -s --eula accept
source /opt/intel/oneapi/setvars.sh intel64
The above script with download the latest mkl, and set the env paths and variables.
