After having enough in searching and reading peoples questions that had the same problem as i have and trying allot of solutions that doesn't seems to help, I'm posting my question.
I want to run my project- qt application, it ran well when i built it on qt4.8.1 32bit and 5.1.1 64bit. now i want to run it on qt5.3.0 32 bit. i installed qt open source with the following configuration:
qt 5.3.0 msvc2010_opengl 32bit.
Since my projects is using qt solutions- qt single application and qt service, i downloaded the packeges, built it in the new environment and placed them in qt/qt5.3.0/5.3/bin and qt/qt5.3.0/5.3/lib.
(I mention this last detail because a simpler qt project that doesn't use these dlls- service and single application runs well in my environment).
Well, when I run my application from qt it doesn't run. When i run the exe file from the release folder i get the following error:
This application failed to start because it could not find or load the qt platform plugin "windows". reinstalling the application may fix this problem.
I tried all creative ideas:
note: I see that automatically the build arainged the release folder with the folowing struck:
plugin folder with all plugins in it.
platform folder with the hole list of platforms: qwindows.dll, qminimal.dll...
and also put straightly the dlls: qwindows.dll, qwindowsd.dll
libEGL.dll
libEGLd.dll
qt.conf with the data:
[Paths]
Plugins=C:...\build-____-Desktop_Qt_5_3_0_MSVC2010_OpenGL_32bit-Release\release\plugins
I used the dependency walker that told me that the IEShims.dll is missind, so I brought it to the release folder from: C:\Program Files (x86)\Internet Explorer.
Now the dependency walker tells me:
Warning: At least one module has an unresolved import due to a
missing export function in a delay-load dependent module.
I see that the Qt5core.dll->link checksum member in the dependency is marked with red, and also I see it takes it from:
C:\Qt\Qt5.3.0\Tools\QtCreator\bin
so I bring to the release folder the Qt5Core.dll from:
C:\Qt\Qt5.3.0\5.3\msvc2010_opengl\bin. then I get the following message:
the procedure entry point
?bytearrayToDouble#QLocalePrivate##SANPBDPA_N1#Z could not be located
in the dynamic link library
c:/Qt/Qt5.3.0/Tools/QtCreator/bin/Qt5Gui.dll
so maybe its wrong to do so.
what else can i do???

I am using Visual Studio + Qt addon with Qt 5.15.2 x64 and set Run deployment tool to Yes. It seems like this deployment tool is poorly designed and broken. Never understand why Qt cannot make own runtime distibution for Windows like Microsoft did. After deployment when I am trying to open my release exe it just not open. Nothing happens. Yes, I can put it into qt bin folder that weights few gigabytes and it works, but it looks like deploy tool missed some libraries. How to deploy on windows without problems?
(Do not advice me to copy entire Qt bin and remove files one by one and find minimal combination of libraries, I want to make qt deploy automatically)
My errors on app launch:
qrc:/qml/main.qml:3:1: module "QtGraphicalEffects" is not installed

I found 3rd party Qt deploy toolkit for Windows. It just works fine out of box. I think the only way to solve problems with windeployqt is do not use it and switch to something else.
https://github.com/QuasarApp/CQtDeployer
I usually run windeployqt manually, if it help you:
path\to\windeployqt.exe --release --compiler-runtime path\to\release\build
for example
C:\Qt\5.15.2\msvc2019_64\bin\windeployqt.exe --release --compiler-runtime .\release
Update: if you use QML frontend in your app, as you described in question update, then also specify --qmldir argiment, so that windeployqt could find dependencies not only in compiled .exe import table, but also in non-compiled QML text files. See approved solution https://stackoverflow.com/a/39717117/12691808.
I have a project with a dynamic library and an executable that links against it. I can successfully start it with Xcode, but when I try to run it from the command line, dyld complains about the library not being in the install path:
$ /Users/USER/Library/Developer/Xcode/DerivedData/PROJECT/Build/Products/Debug/EXECUTABLE
dyld: Library not loaded: /usr/local/lib/libMyLib.dylib
Referenced from: /Users/USER/Library/Developer/Xcode/DerivedData/PROJECT/Build/Products/Debug/EXECUTABLE
Reason: image not found
Trace/BPT trap: 5
The problem is quite clear: the library isn't in its advertised install path. However, I don't really want to deploy it there, and besides, Xcode still manages to start my program.
How can I run my program without installing the library in /usr/local/lib?
If you're relying on a dylib, then it needs to be installed in the appropriate location.
Using a framework might help, as you can package it in your application, using #executable_path...
But then, of course, you won't be able to share it across different applications.
So basically, you need to tell Xcode to install your dynamic library.
This can be done in your build settings, in the Deployment section.
Mainly, Deployment location, Installation directory, Skip install, etc...
Note that you can also do this for frameworks, installing them into /Library/Frameworks/
Hello fellow programmers!
I have written a video player using Qt. Everything works fine on my Mac, but when I use macdeployqt to deploy my application and I open the result, I am getting the following message:
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded
WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no objectName ) to Phonon::AudioOutput ( no objectName ).
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded
...
And of course it doesn't play audio (in my machine or in another). Maqcdeployqt does include the other parts of Qt and the 3 party libs wo problems. Its just the damm Phonon.
I feel that i'm making a dumb mistake but i just cant find it.
The otool log of my app shows:
#executable_path/../Frameworks/phonon.framework/Versions/4/phonon (compatibility version 4.4.0, current version 4.4.0)
As the only reference of phonon.
I read in the documentation of qt the following:
"The Mac deployment tool can be found in QTDIR/bin/macdeployqt. It is designed to automate the process of creating a deployable application bundle that contains the Qt libraries as private frameworks.
The mac deployment tool also deploys the Qt plugins, according to the following rules:
-Debug versions of the plugins are not deployed.
-The designer plugins are not deployed.
-The Image format plugins are always deployed.
-SQL driver plugins are deployed if the application uses the QtSql module.
-Script plugins are deployed if the application uses the QtScript module.
-The svg icon plugin is deployed if the application uses the QtSvg module.
-The accessibility plugin is always deployed. "
Maybe i have a debug version of phonon? I don't know, i have tried to deploy the debug and the release versions and none have worked.
Also i founded a related problem in this page:
http://www.justinfx.com/tag/phonon/
So i included a folder named 'PlugIns' in my bundle with the phonon_backened folder from my system inside of it after the deploy: it played audio on my machine (but it didn't play it on another) and my app crashed at the end so that cant be the way.
I'm using c++, Qt 4.8.5, the phonon from the SDK (i didn't install any version of phonon, i just installed Qt), and Mac OS X (10.6.8)
I would love to hear any idea or suggestion.
Thanks in advance.
I didn't find the source of the error, but I bypassed it by macdeploying the phonon example from the qt examples folder on another Mac (i.e. Lion). It included the folder 'Plugins' inside the bundle with all the phonon stuff, so I include now that folder into the bundles macdeployed in my Snow Leopard manually. It is ugly but it works from now.
If anyone knows the way to really fix the issue I will be happy to hear it.
I used py2app (neither pyinstaller nor cx_freeze worked) and it created the app distribution folder almost perfectly, except it did not copy the phonon backends. Running macdeplpyqt did not help.
The location of your plugins in your app structure is MyApp.app/Contents/PlugIns so I copied over the folder from Qt install (/Developer/Applications/Qt/plugins/phonon_backend/ ) into the PlugIns folder. That still gave the same error.
Digging in further I saw that MyApp.app/Contents/Resource/qt.conf file is expecting the plugins to be in the Resource/qt_plugins folder so I made a symbolic link from from PlugIns MyApp.app/Contents/PlugIns to MyApp.app/Contents/Resource/qt_plugins and everything works now.
im just starting out with FreeSwitch, i downloaded via git, and am trying to build in VS
all i need i believe are the dlls of mod_managed, as my goal is to manage FS via .net
but i get 248 errors, most look something like this:
Error 5 error C1083: Cannot open source file: '....\jpeg-8d\jaricom.c': No such file or directory D:\FreeSwitch\freeswitch\libs\win32\libjpeg\c1 libjpeg
btw, i searched windows and cannot find any such file anywhere on my pc.
I tried
cleaning the solution first, but it did not help
moving the file to a path without spaces
downloading with autocrlf=false
building on another machine
but none of these steps helped
anybody have any idea?
if i can just download the dlls i need, i wouldnt mind skipping this step altogether
environment
win 8 64bit
visual studio 2012
thanks a million
The libjpeg sources are not in the git sources but are normally downloaded during the build process. If you build the entire solution that should not be a problem since it has the project dependencies set: libjpeg.2012 depends on Download libjpg.2012, which means the latter gets built before the first. All Download libjpg.2012 is run a cscript which downloads libjpeg from http://www.ijg.org/files/jpegsrc.v8d.tar.gz (see inside the project file).
So if you do not have the sources, either you are building incorrectly (not in VS for instance, or with a broken solution file) or the download script is broken. In that case, you should inspect the output: I assume it shows errors when it can not download the libs.
I'm trying to deploy my simple Qt project like a hello world.
I build it successfully and can also execute it on Qt-Creator. However, I can't execute the binary directly in the release folder due to some shared library errors.
So I just copy some essential librarys to the release folder such as qtcore.dll and qtgui.dll, but I can't still execute it.
How can I deploy my simple Qt project? Is there an another step to deploy it?
You also need to deploy the MINGW runtime dll (mingwm10.dll). This file is located in your Qt\2009.5\mingw\bin directory.
Also pay attention to whether your application is compiled in debug mode or release mode. I just made the test with an hello world type application and Qt Creator. In the debug folders, I copied libgcc_s_dw2-1.dll, mingwm10.dll, QtCored4.dll and QtGuid4.dll and it works.
Pay attention to the d in dll names, which stands for debug: QtCore d 4.dll.
See Qt 4.6: Deploying an Application in Windows.
For Qt 5, check this page.
If you don't want to have dependencies with qt/mingw dlls you should compile qt statically as explain here: http://qt.nokia.com/doc/4.6/deployment-windows.html#static-linking.
You may also use static linking, just add this line into the .pro file:
QMAKE_LFLAGS += -static-libgcc
I found the solution here and successfully tested on WinXP with QT creator 2.2.0
Try running dependency walker on it (http://dependencywalker.com/) to see which dlls are missing?
Generally, you won't need to move those Qt libraries into your local folder since the Qt installation should've added those libraries into your path.
One possibility is that you built debug, and the Qt debug dlls are named differently
copy all the qt dlls to your windows directory directly "C:\Windows\" and there will be no qt dll error
100% working and simple
nb: do not create a qt dll folder in your windows directory post them as they are
