Hello Everyone,
I want to run either a Squeak or Pharo VM as a "service" in Mac OS X.
That means a few things:
* headless operation
* automatically loads when the OS boots
* safely quits when the OS shuts down
* preferably controlled by launchd (launchctl)
I'm sorry if some of us are seeing "double" as I started posting
first on the Pier list. There was some discussion there that has led
me to start experimenting with VMMaker to try and solve my problem
but while I'm doing that, I thought I'd post here. This really
shouldn't be so hard. I see so many screencasts for Seaside done on a
Mac and the one-click installers work so well on a Mac. Surely
someone has tackled this issue before.
The one-click installers work pretty good. They even launch headless
if you start them from the command line with the "-headless" option
but only from a terminal window. You can't start them headless from
launchd because it seems they are Carbon apps which require some
minimal communication with the window server during startup. Sounds
like a contradicted myself but it's true. If you have a login
session, fire up terminal, then run headless that works. If you try
to use launchd you get an error like this:
-headless: kCGErrorRangeCheck : Window Server communications from
outside of session allowed for root and console user only
So, I'm about to try the Pier one-click installer and use VMMaker to
produce a "unix-only" source tree that I compile that does not rely
on Carbon to see what will happen.
Any help appreciated :-)
Thanks in advance,
-- Aaron
