sndfile-sys's Introduction

sndfile-sys

Rust FFI bindings to libsndfile.

Notes

MSVC toolchain

Starting from version v0.1.2 sndfile-sys can use Vcpkg package manager to search for native libsndfile library (thanks to Vcpkg crate):

Install Vcpkg
install static libsndfile library (x86|x64): vcpkg install libsndfile:x64-windows-static
Add Vcpkg path (e.g. d:\vcpkg) to VCPKG_ROOT environment variable
Add -Ctarget-feature=+crt-static to RUSTFLAGS environment variable

This search method affects MSVC toolchain only. You can disable it completely with environment varible VCPKGRS_DISABLE set to 1.

Use can link to dynamic libsndfile (not recommended for MSVC toolchain):

Install dynamic libsndfile library with command: vcpkg install libsndfile:x64-windows
Delete RUSTFLAGS environment variable
Set VCPKGRS_DYNAMIC environment variable to 1

Starting from version v0.2.2 sndfile-sys can use PkgConfig to search for native libsndfile library (thanks to pkg-config-rs crate):

pkg-config changes needed on ARM Macs

Homebrew on ARM Macs now uses /opt/homebrew/ instead of /usr/local as its default installation path. This causes builds with sndfile to fail as libsndfile can't be found outside of /usr/local.

The change to using pkg-config to search for libraries in e46f1a9 allows the library to be found as expected under /opt/homebrew, but I notice that it hasn't been published yet. Any chance of getting a release with this change?

Thanks for the handy library 🙏
