I've to say... why is so hard to deploy Qt5 in OS X?
After a lot of pain... and discovering this script: https://gist.github.com/lasconic/5965542 and this custom macdeployqt: https://github.com/MaximAlien/macdeployqt I was able to deploy in OSX... but audio is not working.
I've a simple SoundEffect element:
SoundEffect {
id: ring
loops: 1
source: "alarm03.wav"
}
it works fine running in debug/release mode from Qt Creator... but as soon as I run macdeployqt I start to get this error: using null output device, none available
and no sound is played.
Then I found that it could be the audio plugin missing... so I copied the plugins/audio folder to my app package.
Then I start to get an error in startup and the sound starts to play but it runs for about half second... and stops with another error.
The error in startup: http://pastebin.com/TFBgswfb
The error when try to play the sound: http://pastebin.com/KjQ3JCXJ
The error in startup I found that was because it was loading libraries from the app package and from my Qt installation (why??) so I renamed my installation folder to test... the error in startup disappeared... but the first error playing the sound returned.
So I'm out of ideas about what's happening... the only thing I know is that Qt needs a easier deployment system.
Versions: Qt 5.2 - Clang64 - Qt Creator 3.1
PS: My .pro file contains:
QT += sql multimedia

So I just migrated a working application from Qt 6.1.2 to Qt 6.4.2. Pressed play in QtCreator and everthing ran, particularly the connection to a remote server which is done via HTTPS. I use QSslSocket::supportsSsl() to check that everything is ok with SSL and if it's not I close the application. So the fact the application opens means that everything is where it is.
I do however get this in the QtCreator console:
qt.tlsbackend.ossl: Failed to load libssl/libcrypto.
However it does work fine. I have tested.
Once I have this working I run windeployqt by doing
PATH/TO/windeployqt --qmldir PATH/TO/qmldir PATH/TO/myapp.exe
It runs and no errors. But now the application won't run neither from QtCreator (pressing play) nor from double clicking the executable. QtCreator console now throws THIS error:
qt.network.ssl: No functional TLS backend
I made sure that the libcrypto and libssl libraries (the same one in the OpenSSL directory installed by Qt Maintainer and in the bin directory of QtCreator) are in the executable's directory.
But I have no Idea why it is not working anymore. This exact same process worked on Qt 6.1.2 with no issues.
Any ideas?
EDIT: UPDATE: So I've been fooling around. And I found the following interesting tidbit. If I delete the QtCore6.dll from the executable directory where I ran the windeployqt, then I can launch the application from QtCreator again. I don't know if this helps anyone help me, but I'm putting it here just in case.
I wrote a program in Qt:
Qt Creator 3.5.1 (opensource)
based on Qt 5.5.1 (MSVC 2013, 32 bit)
Windows 8.1 64-bit
My program is running fine in Qt creator.But I want to execute it in other computers on all Windows without installing Qt. I copied all required .dll files next to the .exe file (Release build) with windeployqt.exe.
When I start the.exe, nothing happens.
No GUI showing up, no error that a .dll is missing. But I see my application in 'ProcessExplorer'.
This happen for even very simple program.
Here's a screenshot of my Dependency Walker screen for simple application:
I had exactly the same problem and as you, I had no error message or any output whatsoever. I solved the issue when I added the QML path to my deployment.
On this page, windeployqt, you will see the commmand:
windeployqt --qmldir < path-to-app-qml-files> < path-to-app-binary>
Here the command with the qml flag.
C:\Qt\5.10.1\mingw53_32\bin\windeployqt.exe --qmldir C:\My_project C:\My_project\build-My_project_MinGW_32bit-Debug
It seems you are using QML.
did you have a look at stdout / stderr? I have had that problem when my QML file was not loadable / path was incorrect.
Also settings environment variable QML_IMPORT_TRACE=1 helped me to spot these kind of problems.
I have application created with QT5 and Visual Studio 2013. I also use QT WebEngine in my application.
My application works fine in windows 7 (32 bit) . For some reason i need to run it in windows xp sp3 (32 bit).
When i run it, I get the following error:
The procedure entry point strnlen could not be located in the dynamic link library msvcrt.dll
I press OK several time and it goes away and my QMainWindow will pop out, But its totally BLACK and i see the following errors in debugger.
class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): Could not initialize EGL display: error 0x3001
class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): When using ANGLE, check if d3dcompiler_4x.dll is available
The d3dcompiler_47.dll is in application directory too.
Whats wrong here?
UPDATE 1
I placed 3dcompiler_46.dll in executable's directory and this is what happened.
I still get The procedure entry point strnlen could not be located in the dynamic link library msvcrt.dll error but after i press Ok, I get the following error as well.
The procedure entry point _except_handler4_common could not be located in the dynamic link library msvcrt.dll
The QMainWindow is still BLACK and the errors about ANGLE is the same.
UPDATE 2
I build QT for Windows XP with following configuration
configure -release -opensource -opengl desktop -target xp -platform win32-msvc2013 -angle -icu -nomake examples -prefix C:\QT-Compile
I replaced QT dependency and ran my application, I got the following errors:
The application has failed to start because icuin56.dll was not found
The application has failed to start because icuuc56.dll was not found
I tried to find them in QT directory (C:\QT-Compile) and i couldn't but i had them on main machine that run in Windows Seven, I placed them next to executable and application run successfully and previous errors are gone, However, The QMainWindow is still BLACK and i have the following errors in my debugger in run time.
QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
bool __thiscall QOpenGLTextureBlitter::create(void) Could not link shader program:
Whats wrong now ?
UPDATE 3
This is how i configured QT.
configure -release -opensource -opengl dynamic -target xp -platform win32-msvc2013 -icu -nomake examples -prefix C:\QT-Compile
I used windeployqt.exe and placed required DLLs and ... next to executable.
Ran application in windows xp and i keep getting following errors then application crash.

The first error about msvcrt.dll is about not including visual studio runtime dlls with your binary file. It seems that on win XP machine these libs are different then the ones your app is linked against
The next two errors are about failing to start up ANGLE probably due to mismatch of MS VS runtimes that you have encountered previously.
Basically, just put msvcr110.dll and msvcp110.dll in your folder (or provide means to install MS VS Redistributable for 2013 Studio)
Here is detailed deployment doc from digia - http://doc.qt.io/qt-5/windows-deployment.html
Also i would advice you to use qt's tool windeployqt.exe as a part of deploy process.
Usage is simple - windeployqt.exe path/to/your/binary/file.exe
It will copy almost everything you app needs to run your app everywhere without bothering you to include some plugins and dlls etc (though it will not copy mentioned above MSVS runtime dlls)
Also if you are interested a post about using different opengl for qt5 built dynamically loading of graphical drivers ( tries to use default opengl -> is fails tries to use ANGLE -> if fails, tries to use opengl software (libmesa) ) - http://doc.qt.io/qt-5/windows-requirements.html#dynamically-loading-graphics-drivers
It's a bit more complicated then in Qt4, but when you finally handle it properly, it will be more fail safe even on machines with no graphical drivers or no direct X support or launched through VPN
UPDATE
It seems that both desktop opengl and ANGLE fails for you (which would mean, that you have OpenGL implementation version less then 3.0 (default on win xp has 2.0) for desktop opengl to fail and you don't have DirectX 11 or DirectX 9 correct drivers installed (for ANGLE to fail).
This would mean that this is either virtual machine or window without any drivers. To fix this issue, please include opengl32sw.dll (libmesa) to you executable file as well. This is another fallback in case both desktop and ANGLE failed.
You can take in from the folder where your QtCreator installed in folder /tools. Or download it here - http://download.qt.io/development_releases/prebuilt/llvmpipe/windows/
depending on your arch.
Also, try to put d3dcompiler_46.dll from your win xp next to your executable. This might fix runtime error and will allow to launch ANGLE - https://bugreports.qt.io/plugins/servlet/mobile#issue/QTBUG-44985
Update 2:
Let's get it line by line.
You've got The procedure entry point strnlen could not be located in the dynamic link library msvcrt.dll warning because of either you have win XP with not SP3 but SP2 (microsoft dropped support for win XP SP2 for MSVS 2013) - more details here where there is the same issue. Or there is the same bug here that would basically advice to use opengl software.
Now, the errors you see in log:
class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): Could not initialize EGL display: error 0x3001 - this is failure of OpenGL desktop, since you don't have Open GL 2.0 -> proper graphical driver.
class QWindowsEGLStaticContext *__cdecl QWindowsEGLStaticContext::create(class QFlags<enum QWindowsOpenGLTester::Renderer>): When using ANGLE, check if d3dcompiler_4x.dll is available - ANGLE is failed. Because either - qt uses mvcrt.dll for MSVS 2013 that does not support your Win XP SP2 anymore or you don't have d3dcompiler. Perhaps it will work with Qt 5.4 built with MSVS 2008 or MSVS 2012.
Failed to load opengl32sw.dll (The specified module could not be found.)
class QOpenGLStaticContext *__cdecl QOpenGLStaticContext::create(bool): Failed to load and resolve WGL/OpenGL functions - These errors relates to missing opengl32sw.dll file. Which i've already provided link for you to download and put to executable.
And app crashes because Qt was not able to run any of OpenGl modes at all. So basically all you can do is force app to use OpenGL software (i provided link for you how to do this numerous times, please read those guide.) or use qt 5.4 and try to run angle. OpenGL software may not run smoothly and have some problems with complex graphical interfaces but this is basically the only thing that is left.
We met the same problem in win 7, solved by install the graphics card driver
I have found another solution as a side option to switch from opengl to software rasterizer and remove these messages:
Could not initialize EGL display: error 0x3001
When using ANGLE, check if d3dcompiler_4x.dll is available
Because in mine case it was the VirtualBox environment which currently having problems with the OpenGL/DirectX (https://forums.virtualbox.org/viewtopic.php?t=82614&start=15#p408392) implementation, then i have tried to search for a solution and somehow workaround the render.
The QT itself have has an option to switch or disable several builtin options w/o need to rebuild anything. Such as is described here:
https://doc.qt.io/qt-5/windows-requirements.html#dynamically-loading-graphics-drivers
It is possible to provide a JSON-format configuration file specifying which OpenGL implementation to use depending on the graphics card and driver version. The location is given by the environment variable QT_OPENGL_BUGLIST. Relative paths are resolved using QLibraryInfo::SettingsPath or QStandardPaths::ConfigLocation. The file utilizes the format of the driver bug list used in The Chromium Projects. It consists of a list of entries each of which specifies a set of conditions and a list of feature keywords. Typically, device id and vendor id are used to match a specific graphics card. They can be found in the output of the qtdiag or dxdiag tool.
The qtdiag tool is stored basically near the qmake executable. You can additionally run it to diagnose the end system on other errors.
For the VirtualBox you can try this:
{
"entries": [
{
"id": 1,
"description": "Software OpenGL rasterizer (opengl32sw.dll)",
"os": {
"type": "win"
},
"vendor_id": "0x80EE",
"device_id": ["0xBEEF"],
"driver_version": {
"op": "<=",
"value": "5.1.38.22592"
},
"features": [
"disable_desktopgl", "disable_angle"
]
}
]
}
, Where:
disable_desktopgl, disable_angle - When no accelerated path is desired. This ensures that the only option Qt tries is the sofware rasterizer (opengl32sw.dll). Can be useful in virtual machines and applications that are deployed on a wide range of old systems.
the 5.1.38.22592 is a version of the VirtualBox.
This is might be not what you search for, but i didn't found it in time for myself.
I have installed Qt 5.0.1 - 32-bit Version on Ubuntu 12.04. All the programs crash at startup with the following messages :
The program has unexpectedly finished.
/home/manager/Qt5.0.1/5.0.1/gcc/examples/opengl/2dpainting-build-Desktop_Qt_5_0_1_GCC_32bit-Debug/2dpainting
exited with code 0
I tried:
Making the default Qml Application
Running a few example applications.
I switched between the debug and release modes as well, but all crashed with similar message. Surprisingly 'Animated Tiles example' works fine. Any suggestions ?
Edit:
In debug mode this is what i get:
Debugging starts
&"warning: GDB: Failed to set controlling terminal: Inappropriate ioctl for device\n"
RTTI symbol not found for class 'QGLWidget'
RTTI symbol not found for class 'QGLWidget'

I have same problem on Windows with Qt5. As i understood, in qt5 window subsystem moved into plugins and when application start, QApplication object can't find this libraries.
On windows I step-trace my app into Qt code, and find that plugins try to load from folder ./plugins/system where . is folder with our app binary. Also it was a problem with
dependence. Windows specific plugin dependence from libGLES.dll or libGLES2.dll. But GL libs must place in the same folder as app binary, not with plugins.
Correct file tree on Windows look like this
plugins
system
platform.dll
windows.dll
libGLES.dll
MyApp.exe
Try to look in this way.
Firstly check your graphics driver is installed.
Qt5 or higher version supports OpenGL 3.0 or higher, if your system is old one, i think you need to check the graphics card can support OPENGL verion as i mentioned above.
If above things are fine, then i think you need to install some opengl libraries that can be easily downloadable from Ubuntu.

I'm trying to write Qt3D application in windows. I'm getting an error when i trying to compile the program and run it. the error's message is : 'The procedure entry point ??4QImage##AEAAV0#$$QAV0##Z could not be found in the dynamic link library QtGui4.dll'.
my compiler is Microsoft Visual C++ 9.0 and Qt version is 4.8.1.
is there any solution for this?
Do you face the problem in both running from the IDE and standalone exe, and both in debug and release mode. IF some of these work, make sure proper QtGui4.dll is copied to the same path where your executable is getting generated.
