MetaCall Distributable MacOS

This repository contains shell scripts to generate MetaCall binaries for MacOS. The project automates the process of installing MetaCall as a Homebrew formula and creating a distributable package using the brew-pkg tool.

Prerequisites

Contents

Implementation

This brew formulae compiles MetaCall core for ARM64 and AMD64. The installation process has been optimized to install the dependencies in a dynamic way.

The final distributable is generated using a Homebrew extension brew-pkg. It generates a installable .pkg and a portable .tar.gz file. The fork includes some extra features which have been described below.

  1. Recursive library patching: The function recursively processes linked libraries.

  2. Dynamic linking: Uses @executable_path to create relative paths for dynamic linking.

  3. ELF file validation: Checks if the target binary is a valid ELF (Executable and Linkable Format) file.

  4. Library dependency analysis: Uses otool -L to identify linked libraries for the given binary.

  5. Path filtering: Filters library paths to only process those within the specified prefix path.

  6. Relative path calculation: Computes relative paths between the binary and its linked libraries.

  7. Library path updating: Uses install_name_tool to update library paths in the binary.

Usage

MetaCall supports ARM64 and AMD64 architectures at the moment. Clone the repository and build MetaCall using ./build.sh. The script will perform the following actions:

Generated files can be found in the release directory.

Customization

To enable/disable any loaders, modify the formulae and change the args passed to cmake.
