Linker errors on example program

[acgetchell]

Hello,

I'm using this crate and the example program fails due to linker issues.

Suggestions?

Sorry, I'm fairly new to Rust.

Hello! From the first look, a backend is missing. The choice of the backend is left up to the end user:

Does this resolve the issue?

After making the suggested changes:

acgetchell/rust-blas@44fa075

I still get a pretty long stack trace:

ld: warning: object file (../libopenblas_neoversen2p-r0.3.20.a(lapacke_make_complex_double.o)) was built for newer macOS version (11.0) than being linked (10.8)

Looks an issue for macOS with ARM64.

Similar comment exists on OpenBLAS repo
OpenMathLib/OpenBLAS#3032 (comment)

@termoshtt, but then it should have already been fixed in the latest version of OpenBLAS, or has it not yet been released?

I am working for OpenBLAS 0.3.21 blas-lapack-rs/openblas-src#92, it has been merged to master, but readying to publish.

Could you test the master branch using

[dependencies]
openblas-src = { git = "https://github.com/blas-lapack-rs/openblas-src" }

Thank you for taking care of this!

It failed on Linux and Windows also:

Thank you @termoshtt , the master branch fixed it for macOS and Linux:

There still seems to be a vcpkg-related build error on Windows:
