Best way to reboot a system...

Hello,
I'm writing a small Cocoa app which has a button to reboot the  
system. What is the best way to do this? I looked at the reboot C  
function but it requires super-user. I would like to do it cleanly  
like the finder.

Thanks,
- Charles

applicationDidFinishLaunching problems

Hello,
I'm having a problem with using "applicationDidFinishLaunching", BTW  
I'm still really new to COCOA. I have added this to my  
"MyController.m" file and it never seems to get called. I have looked  
at the docs but I'm unclear as too what I'm doing wrong.

- (void)applicationDidFinishLaunching:(NSNotification*)notification {

	NSLog( <at> "Hello World");

}

Any help would be great,

Thanks,
- Charles

Re: applicationDidFinishLaunching problems

You need to set the object/class as the delegate for the Application. 
Usually you do this in the main nib file.

NSPopupButton Question

Hello,
Since I'm new please forgive me for the simple question :-).

How do I quickly get the index number and the title value of the  
selected NSPopupButton ...

So here is what I've got and it works to populate the popup ...

[thePopUp removeAllItems];
[ thePopUp addItemsWithTitles:[NSArray arrayWithObjects: <at> "5 Minutes",  
 <at> "10 Minutes",  <at> "15 Minutes",  <at> "30 Minutes",  <at> "1 hour",  <at> "2 hours",  
 <at> "Never",  <at> "1 Minute", nil]];

I hope this make sense,
Thanks,
- Charles

Re: NSPopupButton Question

Never mind, I just figured it out ... :-P

[thePopUp titleOfSelectedItem];
[thePopUp indexOfSelectedItem];

libjpeg

Hi,

I am trying to create a shared library from the libjpeg source -  
www.ijg.org.  So in the source directory I do the following:

enable-shared

checking whether we are using GNU C... yes
checking how to run the C preprocessor... gcc -E
checking for function prototypes... yes
checking for stddef.h... yes
checking for stdlib.h... yes
checking for string.h... yes

I think it's complaining about --mode=compile, which it's trying to  
parse as the options:
-
m
o
d
e
...

Re: libjpeg

The following procedure worked for me:

	1. Install GNU libtool in /usr/local/bin (the default).
	2.  ./configure --enable-shared
	3.  ln -s /usr/local/bin/libtool ./libtool
	4.  make
	5.  sudo make install

Cheers,
Koryn
