Link error when using dot() in trust-ndarray

operating environment:
Windows 10 home 64bit trustc1.26.2 stable
host x86_64-pc-windows-msvc

extern crate ndarray;
usedarray::{arr2};

US>fnmain(){
    let a = arr2(&[[1., 2.], [3., 4.]]);
    println!("{:?}", a);
}

This one works fine with cargo run.

extern crate ndarray;
usedarray::{arr2};

US>fnmain(){
    let a = arr2(&[[1., 2.], [3., 4.]]);
    letb = arr2(&[[1., 2.], [5., 6.]]);
    let matrix = a.dot(&b);
    println!("{:?}", matrix);
}

Here you will see linking with `C:\Program Files(x86)\~~~\x64\link.exe`failed:exit code:1120 and link error.
I have included VC++ build tools.

I didn't know how to deal with it even when I looked it up.
If you know how to solve this problem, could you please let me know?

The toml file when a link error occurs is

 [dependencies]
ndarray="0.11.0"

It was

 [dependencies]
ndarray={version="0.11.0", feature=["blas"]}
blas-src={version="0.2.0", default-features=false, features=["openblas"]}
openblas-src={version="0.6.0", default-features=false, features=["cblas", "system"]}

Resolved by changing to .

The details of the link error are as follows.
Some of them are omitted because they are long.

error: linking with `C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\HostX64\x64\link.exe` failed: exit code: 1120
