[Rubycocoa-talk] show alert before app starts?

[Axel M. R. <rub...@ro...>]

Hi,
I want to show an alert to the user that the RubyCocoa program needs 
at least Leopard to run. However, since RubyCocoa could not be 
installed on a 10.4 system, the dialog needs to be put up in Obj-C. I 
know how to do that, but not in the main.m file: the application is 
not inited yet.

I know this is not a RC question, but related IMHO: everyone who 
wants to put out rubycocoa programs either needs to
a) bundle the rubycocoa and ruby libraries and/or
b) check the OS version and put up a dialog for the user

else your application silently fails on older OSes, like LimeChat.

Bundling the ruby libraries proved too much work for me, so now i 
'simply' want to inform the user that the app needs a newer OS.
I use NSAlert alertWithMessageText in the main app, before the 
RBApplicationMain is called. The alert is never shown.
I tried initialising the NSApp environment by calling
  [NSApplication sharedApplication] to no avail.

Probably because the NSApp environment is not yet ready, but how do I 
otherwise inform the user in a Maclike way that she needs to upgrade?

tail -f /var/log/system.log is not what I call userfriendly ;-)
