程序需要用到nalgebra-lapack，而它又依賴openblas，每次運行需要編譯openblas-src，之后需要動態(tài)鏈接，實在太麻煩了。

靜態(tài)鏈接才是王道，可以快速丟到其他服務(wù)器上去計算。

cargo.toml內(nèi)容：

[dependencies]

nalgebra = "0.32.2"

approx = "0.5.1"

libc = "0.2.142"

[dependencies.nalgebra-lapack]

version = "0.24.0"?

default-features = false

features = [ "openblas" ]

[dependencies.openblas-src]

version = "0.10.8"

features = ["static","system","cache"]?

指定libopenblas.a的 -L參數(shù)的方法，試了好多辦法，包括config.toml，rustc -- -L /lib64，都不靈。每次都報錯：

could not find native static library `openblas`, perhaps an -L flag is missing?

最后還是這個命令靠譜：

RUSTFLAGS='-L /lib64' cargo build?

或者release版本的：

RUSTFLAGS='-L /lib64' cargo build --release
