Did all you said, modded the openfl version to 1.3.0, then the following:

     - Running command: haxe bin/linux64/cpp/haxe/release.hxml -D HXCPP_M64

    make: *** [linux] Error 1

Edit: So it's not `make linux` it seems, `make flash` seems to do something... Let's try making the server or something...

Edit2: ./server:

    [...]
    Called from flash/Lib.hx line 191
    Called from /usr/lib/haxe/std/neko/Lib.hx line 30
    Uncaught exception - load.c(237) : Failed to load library : lime.ndll (lime.ndll: cannot open shared object file: No such file or directory)

Edit3: Found lime.ndll in some bin folder somewhere. Copied it over to where ./server is. Now it seems to try to bind to 54.244.244.60 (your server's IP) which of course doesn't work. Server.n is a binary format, that can't be the config file, hmm...

Edit4: Oh there are replies that HN doesn't show in edit mode. Okay. Gonna try this!
