Thanks Andre and Volker..

Volker Regarding No 2: on the page of download link, are you referring to "Qt libraries 4.7.3 for Mac" on the right side of the page (i.e. Qt Framework only) or the full SDK on the left?

Kashif

The framework only. That's sufficient, as you happen to have Creator already.

kashifiqb

Thanks Volker,

And for windows also, I will have to download the framework only if i have the Creator already?

Kashif

goetz

Yep. But watch out for the right version (MSVS 2008 or MinGW!)

kashifiqb

Thanks Volker,

Earlier today, i downloaded the Qt SDK for windows, and tried to install it.. it got installed 75% and then some strange errors started coming on like:

9
.
.
.
.8.
.
.
..
7
.
.
.
.
.
and so on..

It installed examples, Creator etc, but was not going further on installation. I opened creator and tried to run an example, but it said it can't find the QMake... This thing annoyed me for most of the time and i couldn't get any result out of it.. Can you elaborate this? I just want to get started with the Qt, and a lot of problems are coming forth..

I think the countdown of numbers is supposed to be there, it's not an error. At least when I'm installing, it countdowns and when reached 0, the installation is ready and working. Installation only needs patience, that might take a while to finish.

kashifiqb

Thanks matrixx..

But the issue is that the countdown repeat some more than 4 times, and was continuing again.. is it the right behavior?

Kashif

Ok, I'm not sure about that. I've seen the numbers only once when installing some older SDK. And to be honest, when installing latest SDK 1.1 I didn't follow the installation process at all, just left it to finish by itself when cooking meanwhile.

kashifiqb

Did you do it for windows? I can't get it running at any cost.. For Mac, will I have to download the build and Interface Tools (206 MB) or the libs only (422 MB) binary package from here: http://qt.nokia.com/downloads/qt-for-open-source-cpp-development-on-mac-os-x

Mine was for 64-bit windows, don't know anything about Macs :)

kashifiqb

Ok, i have installed the mac framework libraries and installed Qt Creator as well.. Now when i try to build the localfortuneserver example, it says "Could not find the Make command to build the project"..

Can anybody help me with that?

Kashif

goetz

Did you install XCode?

kashifiqb

Well i am using Mac in VMWare for the first time and don't know.. Can you guide on how to check if it is installed or not? and how to install it?

Kashif

goetz

Then it's probably not installed. Go and download it from Apple's "XCode page":http://developer.apple.com/xcode/

Go with XCode 3 - the link is at the bottom of the right column. You will need to setup an Apple ID. More info on Qt's "Developing Qt Applications for Mac OS X":http://doc.qt.nokia.com/4.7/developing-on-mac.html. I don't know if XCode 4 is yet supported, but I suppose not.

BTW: It's not allowed to run Mac OS X Desktop version in a virtual machine.

kashifiqb

Volker, it is my first time when I am using Mac..and I dont have Mac with me, thats y i am using VM ware.. Can you tell me why are referring xCode 3? any specific reason? I am reading the article QT programming for Mac..

(1) On windows, i downloaded the framework and tried to install and it said that it cant find mingw.. and directed me towards SDLK installation. I installed the SDK, now i can build QT examples, and the .exe is generated in the respective folder. But when I double click this exe to run, it says "The applicaiton has failed to start because mingwm10.dll was not found. Re-installing the application may fix this problem".. Any help?

(2) Also, after (1) is fixed, if i take this exe to some other system, where QT framework or SDK is not installed, will it work or not?

goetz

Regarding 2: You must deliver all the needed libs, including MinGW DLLs. Please refer to the deployment pages linked earlier in this thread.

kashifiqb

This is somewhat surprising me.. On windows, when i develop applications using Visual C++ (no Qt involved), I simple build the whole project as using in a static library, and as a result, I just deploy the single Exe of my applicaiton; no dll, no lib attached.. I wonder how it is not possible in Qt?

Kahsif

Static linking is not always the best solution. In fact, it is not supported for Qt Webkit module, so this might not work correctly in that case. And you might have problems with Qt plugins too.

Also, you have to keep in mind the licensing issues (please search the forums, it was discussed recently). The base line is that static linking against Qt most probably forces you to release the source code of your app under GPL (but I'm not a lawyer!).

On the mac, one can put all the libraries into the application bundle and that's it. The bundle appears like a single file to the user, there's hardly any installer needed (and in fact Mac users do not like them).

kashifiqb

Volker thank you so much for such an informative reply.. Just one more favour.. how do i know which libraries will be needed?

One more thing: if i bundle the libraries into the application bundle, will the application work if Qt is not installed on Mac?
