Cross Platform Client Server application
-
Hello,
My requirement is to develop a server-client application (not UDP based) that will be able to run on both windows and Mac. The applications won't have any Dialog visible and only there icons will be displayed in the tray near Clock. I have done this work in windows using VC++ 6 very easily, but now the requirement is to develop same applciation for MAC. I haven't used Mac before, and don't know where to start. Googling for cross-platform,i found about -QT- Qt. So I have few questions:
Source Code written in -QT- Qt on windows will be able to compile on MAC? and the output application will be able to run on MAC?
I have installed -QT- Qt Creator IDE, but the compiler is missing. When i download -QT- Qt SDK, it takes much more time to install from online. Any link for offline Installer?
For mac, how to start my application at startup as we do in windows?
I am new to -QT- Qt and MAC, so may be my questions seem too basic to you, but I really need help to do all this.

Take a look at the examples. There is a Future Cookie example that implements a simple client/server infrastructure, and it works on all supported platforms.
On your questions then:
Yes, as long as you use Qt API's and no native API's.
There is an offline installer yes. You can find it "here":http://labs.qt.nokia.com/2011/05/04/qt-sdk-1-1-released/ (and you are right that there needs to be a clearer download link for that too).
That is outside the scope of Qt (on both platforms). I bet Google can help you on that part.

Andre already answered question 1.
An addition to No 2:
You can get precompiled versions of the libraries to install in addition to Qt Creator. Look for the Mac section on the "qt download page":http://qt.nokia.com/downloads (go LGPL). After you're done make sure Qt Creator has catched up for the newly installed libs (Settings Cmd-,; choose Qt4 on the left) or add it manually. You need the path to qmake (I suppose it's in /usr/bin or somewhere below /Developer; I never installed the prebuilt binaries).Regarding No 3:
Depending on when the application should be started, you must create a startup item (started when the Mac boots) or a login item (launched when a user logs in). See "this blog post":http://mattdanger.net/2009/01/scripting-login-tasks-in-mac-os-x/ for an explanation of the latter. There is no builtin support from Qt's side on this, as it is more a matter of installers and the like.Additional comments:
Be sure to read and understand the deployment hints on the "general instructions":http://doc.qt.nokia.com/4.7/deployment.html as well as on the platform specific docs listed at the end of the linked page. -
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..

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

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.

(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?
