Instructions for building dylan on macOS 10.13

Introduction

This is a bit tricky because

1. opendylan-2013.2 (the latest binary for macOS) can't compile a 64-bit dylan
2. Neither can the 2014.1 source release
3. The Boehm garbage collector (a required dependency) is no longer available from homebrew as a universal binary

So you need to build a 32-bit version of the current git source using 2013.2 and then use that to build the 64-bit dylan. 64-bit capability is needed because Apple are soon to deprecate 32-bit binaries.

These instructions assume your downloads go into ~/Downloads and your working files are under ~/Projects/

Requirements

• opendylan-2013.2-x86-darwin.tar.bz2 binary from opendylan.org
• Boehm garbage collector from http://www.hboehm.info/gc/gc_source/
  • gc-7.6.4.tar.gz
  • libatomic_ops-7.6.2.tar.gz
• Latest opendylan from github
• Apple build tools (C compiler etc)
• automake & autoconf (via homebrew)

Boehm Garbage Collector

• Unpack the gc
• Unpack libatomic_ops inside it
• Rename it
• Configure, make and install

    cd ~/Projects
    tar xf ~/Downloads/gc-7.6.4
    cd gc-7.6.4
    tar  xf ~/Downloads/libatomic_ops-7.6.2/tar.gz
    mv libatomic_ops-7.6.2 libatomic_ops
    ./configure --prefix=/opt/local CFLAGS="-arch i386 -arch x86_64"
    make
    sudo make install

Dylan 32-bit

• Install 2013.2
• git clone and dependencies
• Build current git version 32-bit

    cd /opt/local
    sudo tar xf ~/Downloads/opendylan-2013.2-x86-darwin.tar.bz2
    cd ~/Projects
    export PATH=$PATH:/opt/local/opendylan-2013.2/bin
    git clone https://github.com/dylan-lang/opendylan.git
    cd opendylan
    ./autogen.sh
    git submodule update --init
    ./configure --build=i386-apple-darwin17.2.0 --with-gc=/opt/local --prefix=/opt/local
    make
    sudo make install

Then you can set your path to include /opt/local/opendylan/bin (in bash_profile or whatever), and go on to work with 64-bit Dylan.

    make distclean
    ./autogen.sh
    ./configure
    make
