    QT installation problems
    Hello,

    I am trying to install QT SDK (Download Qt, the cross-platform application framework — Qt - A cross-platform application and UI framework).

    I've tried both downloading .dmg offline installation and online installation.

    The first message it throws me is

    "You need C++ compiler to be able to install QT SDK. Please install latest version Xcode first before invoking this installer". I do have xcode 4.2.1, so I click ok.

    I choose "/Developer/SDKs/qtSDK" as installation folder. Then Agree-> Install.

    Then at some point of installation i get this

    "Error during installation process (com.nokia.ndk.api.qtcomponents.simulator.gcc):
    Can't start process install_name_tool." with Ignore, Retry and Cancel options. I clicked several times retry, doesn't help.

    So, i cancel installation, as clicking ignore throws me many other errors.

    Then I tried to install QT using homebrew as follows:

    brew install qt

    wich threw me this warning messages:

    Warning: Xcode is not installed! Builds may fail!
    Warning: It appears you have MacPorts or Fink installed.
    Software installed with other package managers causes known problems for
    Homebrew. If a formula fails to build, uninstall MacPorts/Fink and try again.

    Now, why it doesn't recognize xcode?

    I've checked bug-tracker for qt, found similar problems other users have been having (not exactly the same), and hasn't been resolved yet.

    I would appreciate any help I can get,

    Thanks in advanced

    Yes, same issue... QT fails to install because it fails to recognize XCode? Does anyone have a solution for this? We need to get QT installed, currently at a stand still.

    Thanks!

    I would say that the QT developer Network site might have the awnsers to this one, I beleive they have a
    forum over there as well.

    Qt Developer Network

    Sorry I cant help you more, but I don't have QT installed myself.

    Good luck with it.

    Regards Mark

    Hey, so I posted this a while ago and couple weeks later after posting it i did manage to install the Qt. Unfortunately, I can not help you - I don't know what was different the time installed it successfully. The installation went smooth without any problems and i have no idea what i did different that time - didn't downgrade/upgrade anything. It was a totall voodoo for me.

    Try to do the online installation and, I assume you're installing 64-bit version, try to install 32-bit one. Also, I on successful installation, i didn't place it to the developers folder (e.g., it is recommended that you do, but i dunno - that's the only way i could make it to run).

    GCC is not found
    I had the same problem today. I just installed Xcode for Lion and have not used it. After getting the error, I opened a shell and typed "gcc" and got "command not found". Then I opened Xcode, accepted the terms of usage stuff and _downloaded_ and installed everything that was not installed by default. The first thing that went in was the "command line tools". I believe this is what gave me my gcc back and after that the Qt install worked and did not throw any warning.

    2 cents!
