I have been using Xcode to develop an application in Objective C++. All of a sudden I cannot run the latest version using Cmd-R.
Here are the symptoms:
The app builds OK. But then, as Xcode tries to run it, a dialog box appears saying "Type the name and password of a user in the 'Developer Tools' group to allow Developer Tools Access to make changes." There is a flippy triangle labelled "Details;" flipping it discloses this:
Right: system.privilege.taskport.debug
Application: taskgated
Well, I am not in the Developer Tools Group; alas, I don't work for Apple. All I can do is Cancel the dialog.
Up comes another dialog box. This one says "Type the name and password of a user in the 'Developer Tools' group to allow gdb-i386-apple-darwin to make changes. This time the flippy triangle discloses
Right: system.privilege.taskport.debug
Application: gdb-i386-apple-darwin
I cancel this dialog too.
Now I get an alert box informing me that my application quit unexpectedly. Actually this covers an alert box saying "Error starting application <name of app>. Unable to find Mach task port for process-id nnnnn: (os/kern) failure (0x5)."
-------------
The problem seems to be in the connection between Xcode and the app. If I go to the application that Xcode has just built, in ~/Library/Xcode/<stuff>, I can launch it from the Finder.
Hardware: Mac Book Pro, model 5.3
OS: Max Os X 10.6.8
Xcode 4.0.1
Thanks in advance to anyone who can tell me what's going on here, or how to fix it.
