Do not depend on unnecessary things

usamec commented 4 years ago

This crate depends on openssl-sys, which requires system installation of libssl-dev (or something similar). This is completely silly for crate providing math.

I agree, but we have no option to download the archive of MKL without SSL.

Is it possible to use system installed binaries somehow (e.g. curl)?

termoshtt commented 4 years ago

We have some options:

(a) Use curl-rs (Current)

Windows, macOS has default TLS library, so we do not need to install anything
Linux does not bundles TSL library, but they can be installed using package manager, e.g. apt install libssl-dev

(b) Use `curl` external as program

Recent Windows 10 includes curl compatible with Linux one
I do not know macOS
Linux does not bundles curl program, but we can easily install it apt install curl

(c) Use reqwest or other lightweight Rust HTTP+TLS crate ( #17 )

We needs tokio or other async runtime

If we focus on using non-x86 environment, it will be worth trying to omit openssl-sys dependency. However, Intel-MKL itself assumes x86 environment and openssl-sys is easy to use on these platforms.
