XCode is not building my application because of some random thing.

Question

I have no idea what this error is about, the deadline for that application is tomorrow. I have no idea what is it about but it is refusing to compile. It is a giant project with over 150 source files and with about 20 3rd party dependencies.

Internal error occurred while creating dependency graph: -[PBXTargetBuildContext ]: unrecognized selector sent to instance

I would really appreciate any help. This is freaking me out as it worked perfectly fine. XCode has activated its "break in the last second mode". It is a hidden feature designed to drive developers mad.

XCode uses advanced heuristic algorithm to determine how important that project is. If it is important the following code executes:

- (void) goNuts
{
    [popups displayAllPossiblePopups];
    [build failWithError:[error someRandomIrrelevantError]];
}

And yes, I have rebooted my Mac. I am running XCode 3.2.2 but I don't think that matters as I haven't updated anything else because I always cancel those irritating update pop-ups. I wish there would be an "i don't give a crap" mode which would disable all pop-up windows.

Here is a picture I drew to symbolize my frustration

Edit:

@Koning Baard : Thanks you've saved my life. I was literally ripping my own hair out because of that. The person who changed that and then committed the change better have an explanation for it.

that picture is a joke by the way

My Works very nice but when I change my TARGETED_DEVICE_FAMILY from iphone to ipad I got this erros: Internal error occurred while creating dependency graph: -[PBXTargetBuildContext ]: unrecognized selector sent to instance 0x200f16140

Any one know why ? I cannot buld a iPad App ? Thanks

Try changing TARGETED_DEVICE_FAMILY to iPhone, if it is iPad. Maybe that will work.

Also, try building it from the command line:

$ xcodebuild -project MyAwesomeProjectThatMakesXcodeSuckAndMakesMeVeryFrustrated.xcodeproj -alltargets

(does SO's syntax highlighter really see MyAwesomeProjectThatMakesXcodeSuckAndMakesMeVeryFrustrated as a symbol?????!??!?!//?/?)

---

If that also sucks, try creating a brand new Xcode project, import all resources, files and source code and recreate all targets, etc...
