QT SDK installation fail on mac OS X

[dfcmrf]

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

the same problem for me with Qt SDK 1.2.1. I've previously installed Xcode 4.3

but the same message : "You need a C++ compiler to be able install the Qt SDK. Please install the latest Xcode first before invoking this installer!"

any idea to solve this issue ?

thanks in advance

Issue is solved !!

here is the anwer :
XCode 4.3 is not installed with command line tool by default.
and Qt SDK installer needs this Xcde commande line tool to install Qt libraries and Qt Creator on your Mac.
Thus after having installed XCode 4.3, just install command line tool (via the preference menu of Xcode).

Then you can install Qt creator with out any error message...
enjoy...
