DO NOT DO THIS ANYMORE. The following script installs a 32-bit version of Neko, instead of the 64-bit version that comes with the Haxe 3 install. Your Neko install should match your OS X install, which means unless you are running an OLD system, you want the 64-bit version. OpenFL does properly support 64-bit Neko, and expects this on 64-bit sys…

install.sh

#!/bin/sh


# Download Neko

curl -L http://nekovm.org/_media/neko-2.0.0-osx.tar.gz > neko-2.0.0-osx.tar.gz


# Extract and copy files to /usr/lib/neko

tar xvzf neko-2.0.0-osx.tar.gz
sudo mkdir -p /usr/lib/neko
sudo cp -r neko-2.0.0-osx/* /usr/lib/neko


# Add symlinks

sudo rm -rf /usr/bin/neko
sudo rm -rf /usr/bin/nekoc
sudo rm -rf /usr/bin/nekotools
sudo rm -rf /usr/lib/libneko.dylib

sudo ln -s /usr/lib/neko/neko /usr/bin/neko
sudo ln -s /usr/lib/neko/nekoc /usr/bin/nekoc
sudo ln -s /usr/lib/neko/nekotools /usr/bin/nekotools
sudo ln -s /usr/lib/neko/libneko.dylib /usr/lib/libneko.dylib


# Cleanup

rm -r neko-2.0.0-osx
rm neko-2.0.0-osx.tar.gz


# Rebuild haxelib

cd /usr/lib/haxe/std/tools/haxelib
sudo haxe haxelib.hxml
sudo cp ./haxelib /usr/lib/haxe/haxelib

Is this because I didn't do this?

~$ haxelib run openfl setup

Uncaught exception - load.c(237) : Failed to load library : nme.ndll (dlopen(nme.ndll, 1): image not found)

Why does it mention nme at all? Does openfl already come with nme?

Yes, it is. This bash script solves that issue.

I had this issue but I was able to copy the nme.ndll from /usr/lib/haxe/lib/openfl-tools/1,0,10/ndll/Mac and then place it in /usr/lib/haxe/lib/openfl-tools/1,0,10/ndll/Mac64/ this solved the issue for me after that I was able to complete the setup. @jgranick also mentions this on the openFL threads here http://www.openfl.org/developer/forums/installing-openfl/error-running-openfl-setup-max-osx-1084/ this worked for me.

OpenFL has full support for 64-bit Mac now, so you should not use this script any more. If you use the Haxe installer (which installs Haxe and Neko), you should be able to get up and running right away with OpenFL. We have support for 32-bit as well, but only expect it when you have a 32-bit system. If you have any problem running Neko, be sure you have the 64-bit version (for most systems)
