[launchd-dev] SMJobSubmit( ) fails but no error is returned

[Karl Moskowski]

I've been trying to use SMJobSubmit( ) to have launchd run my LaunchAgent. The weird thing is, it works on my MacBook Pro at home, but on my iMac it fails - the return code is false, but the outError argument is NULL. Both machines are running up-to-date Snow Leopard and using Xcode 3.2.

Source for the app (a Sparkle utility to check all apps for updates) is at <http://bitbucket.org/kolpanic/coruscation/>. I'd appreciate any insight.

I create a NSDictionary corresponding to the plist, then submit the job with:
	CFErrorRef *error = NULL;
	if (!SMJobSubmit(kSMDomainUserLaunchd, (CFDictionaryRef)plist, NULL, error))
		NSLog(@"Error in SMJobSubmit: %@", (NSError *)error);
	if (error != NULL)
		CFRelease(error);

Below is an example of the plist saved to ~/Library/LaunchAgents/. If I open Terminal and manually use launchctl to load the plist, it works.
	<?xml version="1.0" encoding="UTF-8"?>
	<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
	<plist version="1.0">
	<dict>
		<key>Label</key>

		<string>/Users/karl/Projects/build/Debug/Coruscation.app/Contents/MacOS/CoruscationAgent.app/Contents/MacOS/CoruscationAgent</string>

			<integer>9</integer>
			<key>Minute</key>
			<integer>14</integer>
			<key>Weekday</key>
			<integer>5</integer>
		</dict>
	</dict>
	</plist>
