ipp-sys

What is this crate?

This crate provides wrappers of the Intel Integrated Performance Primitives (Intel IPP) library made with rust-bindgen.

Version support

Use the 2017, 2018, or 2019 cargo feature to use IPP 2017, 2018, or 2019 respectively.

Download IPP

Get IPP from https://software.intel.com/en-us/intel-ipp

Usage

Compile IPP statically into your app by setting environment variable IPP_STATIC=1.

You must set the IPPROOT environment variable at compilation time. This is used by the build.rs files to find your IPP installation. Typically, this is set using a tool provided by Intel with IPP and run as follows.

On Linux:

source /opt/intel/compilers_and_libraries_2019/linux/ipp/bin/ippvars.sh -arch intel64 -platform linux

On Mac:

source /opt/intel/compilers_and_libraries_2019/mac/bin/compilervars.sh -arch intel64 -platform mac

On Windows:

"C:\Program Files (x86)\IntelSWTools\compilers_and_libraries_2019\windows\ipp\bin\ippvars.bat" intel64

In Cargo.toml, include ipp-sys as a dependency with a feature to select the IPP version used:

[dependencies]
ipp-sys = { version = "0.4", features=["2019"] }

Now, you can use ipp_sys in your crate. You might like to check that you compiled the correct version by doing something like:

// Get the version from IPP at runtime.
let linked_version_major = unsafe{ (*ipp_sys::ippGetLibVersion()).major };
let linked_version_minor = unsafe{ (*ipp_sys::ippGetLibVersion()).minor };

// Compare the runtime major version with the compile-time major version.
assert_eq!( linked_version_major as i32, ipp_sys::IPP_VERSION_MAJOR as i32);
// And compare the minor version, too.
assert_eq!( linked_version_minor as i32, ipp_sys::IPP_VERSION_MINOR as i32);
