Installation and Deployment

Hi and welcome to devnet, Did you add @QT += sql@ to your pro file ?

Both your assumptions are almost 100% wrong, so don't worry too much :) In any case, you can use Thiago's "qtchooser":https://qt.gitorious.org/qt/qtchooser.

solved the problem. i just reinstalled qt creator and now it works ...

Yes, thanks :) This is probably one of the reasons twinkle isn't in the brew repo :(

Also I could not installed qt4-dev-tools, is this tool compulsory require?? so please suggest any link of its. Dharmendra

[quote author="belab" date="1368892183"]yes you can[/quote] Thanks, I just didn't want to waste too much time trying it. Hope the setup isn't too tedious.

Hi qxoz Thanks very much for the reply... I really appreciate it

Thank you for your timely response this is helping me understand quite a bit.

You can compile 32 and 64 bits versions on a 64 bit machine? I'm running a 32 bit machine and I find myself having to compile the source to get it to run on VS2012, sadly.

thanks!, I will start with that... :)

Ahhh.... I never knew how that happened!, I thought it was an admin guy doing that :o I will update it now. Thanks

Hi again! i did resolve the problem by include platforms folder(C:\Qt\Qt5.0.2\5.0.2\mingw47_32\plugins\platforms) and it works!! and you could just copy qminimal.dll and qwindows.dll the others are for debug.

About the "\configure.exe not recognized" error: it is qtbase\configure.bat that is trying to call it. qtbase\configure.bat can build configure.exe before calling it. To trigger the build create an empty file qtbase.gitignore This tricks configure.bat and it builds configure.exe Hope this helps. I was getting the same problem with Qt-5.0.2

Now, YES! :-)

Dear All, i have d/loaded: Microsoft Visual Studio 2010 Version 10.0.30319.1 RTMRel Microsoft .NET Framework Version 4.5.50709 RTMRel Installed Version: VC Express Microsoft Visual C++ 2010 01013-532-2002287-70919 Microsoft Visual C++ 2010 when i go again to: tools>options>build and run>compilers the compiler is auto detected but when i click on it and try to click apply and click OK nothing happens to indicate it can use the compiler. when i run a QT example a message comes up: :-1: error: LNK1123: failure during conversion to COFF: file invalid or corrupt. so i am none he wiser, what else can i try. is there an open source compiler that you can recommend and where to go? cheers nubee

Be sure that qtbase is clean before running that. I had similar issues in the past due to that, I did not try with 5.1 but with the dev branch (where it works), and you can also apply https://codereview.qt-project.org/#change,53651,patchset=2 if you want.

I have solved the problem and I dont get any Errors now , but after build and run the example , An empty console terminal opens without any context . How can I understand my program works true or not? This is the picture of program after it runs : !http://up.download.ir/di-ME3W.png(problem_pic)!
