QtCreator vs. Xcode

[basil_fawlty]

First of all:
I am a complete newbie in Qt. I have developed an OpenGL-Project, which should now contain a nice GUI. Thats why I am trying to learn Qt.

I have installed the Qt SDK. I have no problems at all to run the opengl-examples in QtCreator. Now I wanted to integrate Qt in Xcode. I have tried the same example. I have integrated all headers. In the code are no errors, but I get these messages, when push "Build and Run".

Now my questions:

Is it possible that I get this message, because I am not using qmake.

I have tried use qmake and pasted into the terminal the following line: qmake -spec macx-xcode project.pro

but i only get the message qmake: command not found

Is it adviseable to use QtCreator instead of Xcode? Is it possible to compile every opengl code with qt?

I never had used xCode but it seems that it is a lib path problem.
Try to indicate to xCode the path to the Qt libraries

[goetz]

You will have to add at least QtCore and QtGui (and maybe some more) to the list of used frameworks in XCode.

Regarding your qmake problem: You will have to call it by its full path. I don't know where it is located in the SDK. I'd try

@
mdfind -name qmake | grep bin
@

on the command line.

Thanks for your answers: Somehow this qmake isnt working. My qmake file can be found here: /Developer/QtSDK/Simulator/Qt/gcc/bin/qmake

Then I have typed in: /Developer/QtSDK/Simulator/Qt/gcc/bin/qmake -project -o /Developer/QtSDK/Examples/4.7/opengl/untitled

Nothing happens!

My biggest question right now is how to create this .pro-file. Because its not working with me.

Thanks in Advance

[goetz]

The argument to "-o" is the .pro file you want to create. It's unlikely that the path you provided is what you want :)

So, go to a terminal and type:

@
cd /path/to/your/source
/Developer/QtSDK/Simulator/Qt/gcc/bin/qmake -spec macx-xcode project.pro
open project.xcodeproj
@

Regarding your 3rd question: yes that's possible and easy. Both XCode and Qt Creator just call gcc behind the scenes.

Thank you it worked....
