Installation and Deployment

HI, in this forum there are a lot of thread describing and solving your problem. "here":http://qt-project.org/forums/viewthread/34621/ "here":http://qt-project.org/forums/viewthread/30559/ "here":http://qt-project.org/forums/viewthread/29767/ Read these links and try yourself; if you don't reach the goal ask again providing as mush as details possible (input command, command output, environment, .....) Good Luck

[quote author="oneposter" date="1385653570"]It should be a easy environment for MAC OS, Windows and Linux.. with full Power + all Features, but still somehow small and i think static Linking will be the way...[/quote] Buy the commercial license and you are free to use static linking. Or make your app GPLed, then it's also allowed. Use static linking in LGPL and you are asking for a court case ;) LGPL only forces you about Qt libraries, it is not concerned with any other code/ library that you are using. Mixed static and dynamic linking is possible, almost every application uses that, actually.

Thanks for your answers :)

That makes a lot of Qt installed :-D You're welcome ! Since you're have now a working setup, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Hi, With Qt 5, the widgets have been moved to their own module. You need to add @QT += widgets@ to your pro file

Ok - I use this "link.":http://qtcenter.org/wiki/index.php?title=Building_static_Qt_on_Windows_with_MinGW Enter to: <QtSDK DIR>\Desktop\Qt\4.8.1\mingw\mkspecs\win32-g++ And change the line: QMAKE_LFLAGS = To: QMAKE_LFLAGS = -enable-auto-import -Wl That's all. Good Luck!

Download and install 32 bit libraries, or compile them yourself.

Hi, You have another problem first, you are mixing Qt 4.8.1 and Qt 5.1.1 which is a bad idea. So should rather build your program with Qt 5.1.1 which includes also QSerialPort so you won't need QextSerialPort

Hi, I have also comodo installed. My solution: Stop the comodo Run as administrator the installer Restart comodo This works for me. Greetings from Greece

There's a lot of fixing we've had to do. The install doesn't put in the shortcuts any more. We created our own for the Qt + Visual Studio environment set up before Visual Studio 2010 is run. Also found that the 1.2.2 plug-in added the debug Qt5Multimedia component to the Release mode so when run, our release mode could not find Qt5Cored.dll. Easy fix and probably a developer's copy-paste error in the plug-in. Anyway, don't want to bitch, but it went downhill a bit and trying to recover to where we were. About to post a bug we've found.

I'm happy to say all problems are resolved. Thanks once more

Let's rewind a bit. You are running Linux Mint which is a Ubuntu/Debian derivative -> Ok ? You have a program/library that uses Qt 4 and QtWebkit -> Ok ? You are using cmake to build that project -> Ok ? Then unless you need the latest Qt 4, you can use your distribution packages and install the development packages for Qt 4 e.g. @apt-get install libqtwebkit-dev@ Then you should be good to go

You have several options here. You can install the version provided by ubuntu: @ sudo apt-get install qt4-qmake @ The version depends on Ubuntu you are using, however. Or you can download the prebuild package from Qt Project "archive":http://download.qt-project.org/archive/qt/4.7/. Or you can download the source code and compile Qt yourself. I strongly suggest upgrading to newest Qt 4 version: it's fully source and binary compatible, and you get numerous bug fixes, performance improvements, new features etc. for free.
