Installation and Deployment

Yes it works. I have added the correct MingW\bin directory into the path.

Moving #include <QtOpenGL> first fixed this, I'm guessing an OpenGL or GLM header was included before <QtOpenGL>.

Have code compiling now, by changing: I had missed the decision to drop ICU, now removed from build Build Postgres driver AFTER main build, NOT WITH main build.

Thanks, do you have a link you can refer me to?

Hi, This could be a Qt Quick 2.0 + OpenGL issue. Please see http://lists.qt-project.org/pipermail/development/2013-November/014330.html -- follow the instructions and answer the author's questions when you submit a bug report to http://bugreports.qt-project.org/ This is a simple test: Does your PC support OpenGL 2.0? Does upgrading your graphics card drivers help? Have you developed apps using Qt Quick 2.0 before?

[quote author="kursukani" date="1387829578"]Only on debug-mode the images are show.[/quote]Can you please confirm that you have deployed the correct DLL? qjpegd.dll is for Debug mode qjpeg.dll is for Release mode [quote author="kursukani" date="1387829578"]Its the better solution to use the path to the images instead of .qrc-File?[/quote]They are both supposed to be equally valid solutions. However, you can give it a try and see if it makes a difference.

Then it seems that you didn't get everything installed

ok guys, a fresh install of Xcode 5.0.2 and Qt5.2 did the job! Thanks for your help :) Mario

Sorry, nothing haven't help me so I decided to choose SQLite. Thanks for answers.

Hmmm ... I haven't seen those. What platform are you specifying for qt. I am using macx-clang. What is the version of clang you have on your machine ('clang - v'). I am running 4.2. I didn't have 5.0.2 of XCode but I just updated it and tried kicking off my build again to see if I can hit the errors you are seeing.

I had the same issue with Mint14 (32bit). Using Software Manager and installing "libgl1-mesa-dev" fixed the issue. Examples are now building and running fine

Follow instruction on https://help.ubuntu.com/community/LiveCDCustomization Last year i have build a cd to start on a live cd and server build apache & many app as demo on mysql db... You take a ubuntu install all item you need and after.. burn a dvd from all..

and which one did you installed in your computers?

Hi and welcome to devnet, Are you sure you are deploying the right OpenCV dlls (32/64bits, mvxc/mingw, release build) ? Also, are you sure that you are deploying all needed dlls ? Hope it helps

Actually we need to build kdiff tool which requires qt4.4 libraries but not the whole development environment.

I solved the problem at last. It seems like the problem was ndk directory's long name: mingw32-make: *** No rule to make target '............\downloads\AndroidNdk\android-ndk-r9b-windows-x86\android-ndk-r9b\sources\cxx-stl\gnu-libstdc++\4.8\libs\armeabi-v7a\include\bits\c++config.h', needed by 'main.obj'. Stop. When I copied ndk directory to c:\android-ndk-r9b instead of c:\downloads\AndroidNdk\android-ndk-r9b-windows-x86\android-ndk-r9b ,and after setting the new path under Qt->Tools->Options->Android , it built the project without problems.

Hi and welcome to the Qt Dev Net! I'm sorry to hear that your first experiences were frustrating. Let's try to make things better. There's a little note underneath the long list of downloads that says,[quote]The Windows offline installers are by default ANGLE based. If you want to know more about the differences between ANGLE and OpenGL packages on Windows, please visit "Qt 5 on Windows ANGLE and OpenGL":http://qt-project.org/wiki/Qt-5-on-Windows-ANGLE-and-OpenGL.[/quote] In a nutshell: Qt 5 requires OpenGL 2.0 or higher. If your graphics card does not support OpenGL 2.0 or higher, then you'll need to use ANGLE-based packages instead (those without "OpenGL" in their name). ANGLE is a 3rd-party toolkit that converts OpenGL calls into DirectX calls so that Windows users without OpenGL 2.0 support can use Qt. So in your case, I believe your problem can be resolved by installing the non-OpenGL package instead. By the way, the Online installer is a package manager that lets you choose between the other packages on the Downloads page. Go to your Qt installation folder Launch MaintenanceTool.exe. Select "Package manager" Expand Qt -> Qt 5.2.0. You should see a long list, corresponding to http://qt-project.org/downloads Select "msvc2010 32-bit" and deselect all others

I was able to fix my issue by using vs2010 compiler, after downloading visual studio express 2010 first.
