Thread: The application 'HelloWorld' cannot be opened

  1. #1
    Default The application 'HelloWorld' cannot be opened
    Okay, I am a bit dumbstruck here.
    I have firmware 2.0.2 and it's jailbroken.
    I installed gcc and the necessary tools as per:
    Developing for the iphone using the open toolchain and SDK 2.0 headers - antirez weblog
    (had to add make and ldid to get it to work but apart from that, pretty okay)

    After the app gets installed however I can't open the executable.
    It's there:
    iPhone:/Applications/ root# ls -l
    total 32
    -rw-r--r-- 1 root admin 108 Sep 20 02:38 Default.png
    -rwxr-xr-x 1 root admin 14192 Sep 20 02:39 HelloWorld*
    -rw-r--r-- 1 root admin 812 Sep 20 02:38 Info.plist
    -rw-r--r-- 1 root admin 9 Sep 20 02:38 PkgInfo
    -rw-r--r-- 1 root admin 2399 Sep 20 02:38 icon.png

    ..and the permissions seem right....I think?
    I have no apps installed from the AppStore...which I see often mentioned when people have probs with 'cannot be opened'.

    Oh yes, the application has been signed with ldid -S.

    Anyone with any clues? would sure be appreciated.


    Oh yeah...I should add, this means that the icon is there but when I tap it I get a popup telling me 'The application 'HelloWorld' can not be opened'.

    I'm still clueless (

    Thats weird, I did ldid -s on it...isn't that the app to sign it?

    (tried -s as well as -Sseemed to make no difference)

    Anyhow, thanks, I'll look into it again (

    Well, I'm at a loss, I definitely signed it (ldid -S HelloWorld). No asserts or nothing so seems okay....but no go.

    Darn....I really hope to not have to save up for a Mac.

    "The application can not be opened" usually is a signing problem.

    Just in case have you checked "" directory permissions?

    Well, despite that being a good suggestion - I checked and the attributes seem right, and to make sure I chmodded em to no avail.
    Tried respringing, but get 'not rebuilding cache because pre 2.1'.

    I'm at a loss (

  6. #6 was fixed the moment I installed an app from the appstore. Don't ask why but that seems to add that special something I assume.

    Unfortunately this was after about 5 reinstalls and cygwin reinstalls and whatnot....byt yay! works (o:

    He didn't install his own software. He just downloaded a random app from the App Store. I've had to do this to fox the same issue. It's a mystery as to why this works.
