Cross Compiler for MacOS

Problem

• MacOS is worthy Release Target for a Software since many people use it.
• MacOS is required officially to develop for MacOS(also because of SDKs) and not everyone owns Mac Devices. Thus, Cross Compiling to MacOS is necessary.
• For cross-compiling to MacOS , you require Apple SDK and osxcross (wrapper to Clang).
• Compiling osxcross takes time. Also , Size of osxcross after compilation is >500MB thus making osxcross unfit to compile during CI/CD.

Introduction

• crossmac is Pre-Built osxcross (MacOS cross compiler) with SDK taken from phracker/MacOSX-SDKs.
• Github Actions is used to build crossmac.
• It is heavily compressed(from ~550MB to ~50MB) using zstd.
• It is ideal to use for CI/CD or if you don't want to compile osxcross.
• It's built on Void Linux and works properly on not-old Linux glibc Distributions.

Usage

• Download crossmac and extract it.

• Add lib/ folder of crossmac to LD_LIBRARY_PATH

  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:CROSSMAC/lib/

• Add bin/ folder of crossmac to PATH

  export PATH=$PATH:CROSSMAC/bin/

• Make sure that you have clang or gcc installed (clang is preferred).

• You can use o64-clang / o64-clang++ to target for Intel Mac Devices . You can use oa64-clang / oa64-clang++ to target for Apple Silicon Mac Devices (arm64 devices).

• Refer osxcross for More Information.
