Open Dylan Downloads

Binary Releases


The 32 bit version of Open Dylan IDE does NOT work on 64 bit Windows prior to Windows 8. There is no workaround at this time, unfortunately. We hope to resolve this in an upcoming release.

However, the command line tools should work as the problem is with interaction between threads, GC and WoW64.

All of our source code is available under an open source license in the “dylan-lang” organization on GitHub.

Get Started!

If you’re new to Dylan, you’ll want to check out these handy resources:

Installation on Windows

For installation, double-click on the installer, and follow instructions. You need to have either the PellesC linker or the linker of VC++ 6.0, 7.0 or the current .NET platform SDK installed. PellesC is the best option.

Your environment variables must be set such that the external build system (linker, resource compiler, etc.) can be found. For example, for Pelles C you should set these environment variables in the System control panel (assuming installation in C:\Program Files\PellesC):

INCLUDE=C:\Program Files\PellesC\include;C:\Program Files\PellesC\include\win
LIB=C:\Program Files\PellesC\lib;C:\Program Files\PellesC\lib\win
PATH=C:\Program Files\PellesC\bin;...more...

You may instead start a Pelles C interactive shell and run C:\Program Files\Open Dylan\bin\win32-environment.exe, but this won’t help if you want to run Open Dylan via the Start menu.

Installation on Mac OS X, FreeBSD, Linux

The README file inside the tarball describes installation and basic usage. The easiest way is extracting the tarball in /opt. The Linux platform should have gcc installed, in order to allow linking. Note that these versions only have a command-line compiler and no IDE.

64 bit Linux requires that the Boehm GC is installed (For example, apt-get install libgc-dev on Ubuntu).

Installation from source

You can read more about installing Open Dylan from the source files in the README. This file contains the instructions on how to obtain the source code, the required dependencies and how to build it.
