fakecgo

Documentation

Overview

Package fakecgo implements the Cgo runtime (runtime/cgo) entirely in Go. This allows code that calls into C to function properly when CGO_ENABLED=0.

Goals

fakecgo attempts to replicate the same naming structure as in the runtime. For example, functions that have the prefix "gcc_*" are named "go_*". This makes it easier to port other GOOSs and GOARCHs as well as to keep it in sync with runtime/cgo.

Support

Currently, fakecgo only supports macOS on amd64 & arm64. It also cannot be used with -buildmode=c-archive because that requires special initialization that fakecgo does not implement at the moment.

Usage

Using fakecgo is easy just import _ "github.com/ebitengine/purego" and then set the environment variable CGO_ENABLED=0. The recommended usage for fakecgo is to prefer using runtime/cgo if possible but if cross-compiling or fast build times are important fakecgo is available. Purego will pick which ever Cgo runtime is available and prefer the one that comes with Go (runtime/cgo).
