This is a go-gettable version of the LZ4 library for use in Go code that needs to link against the LZ4 library but wants to integrate with go get and go build. The LZ4 source is currently pinned to the r128 release.

To use in your project you need to import the package and set appropriate cgo flag directives:

import _ "github.com/cockroachdb/c-lz4"

// #cgo CPPFLAGS: -I <relative-path>/c-lz4/internal/lib
// #cgo darwin LDFLAGS: -Wl,-undefined -Wl,dynamic_lookup
// #cgo !darwin LDFLAGS: -Wl,-unresolved-symbols=ignore-all
import "C"
