LIPO

This lipo is designed to be compatible with macOS lipo, which is a utility for creating Universal Binary as known as Fat Binary.

This can be useful in the following scenarios:

  • When using a CI/CD platform (such as GitLab) that does not provide access to macOS or macOS lipo.
  • When using GitHub Actions and looking for a cost-effective solution that doesn't involve using macOS.

INSTALL

Download a latest release from GitHub

For example for Linux on amd64,

$ curl -L -o /tmp/lipo https://github.com/konoui/lipo/releases/latest/download/lipo_Linux_amd64
$ chmod +x /tmp/lipo
$ sudo mv /tmp/lipo /usr/local/bin

Install with go install

$ go install github.com/konoui/lipo@latest

USAGE

$ lipo -output <output-binary> -create <arm64-binary> <amd64-binary>

For example,

$ CGO_ENABLED=0 GOOS=darwin GOARCH=amd64 go build -o amd64 example/main.go
$ CGO_ENABLED=0 GOOS=darwin GOARCH=arm64 go build -o arm64 example/main.go
$ lipo -output hello-world -create arm64 amd64

$ ./hello-world
Hello World

$ file hello-world
hello-world: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64]
hello-world (for architecture x86_64): Mach-O 64-bit executable x86_64
hello-world (for architecture arm64): Mach-O 64-bit executable arm64

Supported Options

-archs, -create, -extract, -extract_family, -output, -remove, -replace, -segalign, -thin, -verify_arch, -arch, -info, -detailed_info, -hideARM64, -fat64
