glue's Introduction

Glue

C++ dependency management is hard, is it possible to make it easy?

Rationale

There's no easy way to manage dependencies in the C++ projects.

Existing solutions rely on customizations/patches applied to 3rd party code and/or some kind of central repository to pull pre-built binaries from.

The problem is that it is extreemely hard and time consuming to patch/pre-build each ever created C++ library.

Inspiration

There are some successful tools which provide OS-specific way to manage 'packages':

Philosophy

Build system should produce binaries from source code. Dependency manager should take care about dependencies. KISS FTW.

Key features

it should be able to pull source code from remote location
it should be able to drive build process for Makefile, GNU Autotools, CMake, Boost.Build, Meson, Scons -based projects
it should be able to install multiple versions of the same library
it should be able to provide dependencies integration for CMake, Meson, Boost.Build build systems
it should be able to deal with the dependencies of dependencies
it should work on Windows, Linux, OS X in a uniform way

dependencies.yml

boost:
  git: [email protected]:boostorg/boost.git
  tag: boost-1.62.0
  build:
    unix:
      - bootstrap.sh --prefix=<%= Glue.install_dir %>
    win:
      - bootstrap
  install:
    unix:
      - ./b2 install
    win:
      - b2

gstreamer:
  file: https://gstreamer.freedesktop.org/src/gstreamer/gstreamer-1.10.1.tar.xz
  build:
    all:
      - ./configure --prefix=<%= Glue.install_dir %>
      - make
  install:
    all:
      - make install
  dependencies:
    - glib

glib:
  # ...

Usage

glue install to install dependencies specified in dependencies.yml
glue generate [cmake|boost|meson] to generate integration files for build system
glue vendor to copy binary dependencies to ./vendor for packaging
