When I open Qtcreator I get the following error message (from a notification box): "The following plugins have errors and cannot be loaded" with the list of the plugins containing errors: CMakeProjectManager, Qnx, RemoteLinux and Valgrind.
When I click over the name of a plugin I obtain some details like that
Could not resolve dependency 'AnalyzerBase(3.1.1)'
Could not resolve dependency 'Core(3.1.1)'
Could not resolve dependency 'ProjectExplorer(3.1.1)'
Could not resolve dependency 'TextEditor(3.1.1)'
I use Linux (ubuntu 14.04) and I have no idea what to do.

Hello I have installed SFML in my M1 chip Bigsur using this tutorial https://www.youtube.com/watch?v=WOyp5n2FmZY and also fixed all the error related to M1 chip.But when I run my project I get this pop ups.
popups
dyld: Library not loaded: #rpath/../Frameworks/vorbisfile.framework/Versions/A/vorbisfile
Referenced from: /Library/Frameworks/sfml-audio.framework/Versions/2.5.1/sfml-audio
Reason: no suitable image found. Did find:
/Library/Frameworks/vorbisfile.framework/Versions/A/vorbisfile: code signature in (/Library/Frameworks/vorbisfile.framework/Versions/A/vorbisfile) not valid for use in process using Library Validation: library load disallowed by system policy
It even showed pop ups for every frameworks I went to settings and gave allow for each of them. But it kept on showing same popup how can I solve this problem in BigSur
I think you will find that the library in question has been quarantined by the operating system. I would suggest:
confirm the quarantine flag ls -l# /path/to/library-or-library_bundle
remove the quarantine flag sudo xattr -d com.apple.quarantine /path/to/library-or-library_bundle
You can also go to your system preferences, then Security & Privacy. On General you see the settings for Allow apps downloaded from:. If you have a message like the one you have mentioned above, it says here "your.framework" was blocked from use because it is not from an identified developer with a button Allow Anyway next to it. Click it.
I am developing a QT GUI for my application using QT Creator (4.11.0).
Recently, our IT updated my OS to Ubuntu 20.04 (from 18.04) - maybe the error is related to that.
I have not touched to project in some month but yesterday wanted to continue developing it.
However, within the IDE there are now thousands of errors highlighted at almost every line of my code. (with highlighted I mean that there is this red background and a red dot beside the line number)
On the very top, it says:
Warning: The code model could not parse an included file, which might lead to incorrect code completion and highlighting, for example.
cstddef:50:10: fatal error: 'stddef.h' file not found
...
The errors that are listed in the IDE are very wired like:
type `QMainWindow`is not a direct or virtual base of `MainWindow` (my class is called `MainWindow`)
I'm pretty sure it is not related to my code:
the code compiles and works fine - it is really just the IDE that is highlighting errors at every line of my code.
I have the same code on a Windows Computer and there no errors are listed in the IDE.
even if I start a brand new QT Widget project the errors appear within the template code provided by the QT Creator.
Since the GCC version changed with the update of the OS, I thought maybe I have to define a new KIT but this also did not help.
Is there anything I can do to fix the issue?
Do I have to reinstall the QT Creator?
I know, pictures are not very well-liked but here I think it might help to understand what I mean with "IDE is highlighting errors":
1. First
~/.profile :
CPATH="/usr/include/clang/10/include:$CPATH"
C_INCLUDE_PATH="/usr/include/clang/10/include:$C_INCLUDE_PATH"
CPLUS_INCLUDE_PATH="/usr/include/clang/10/include:$CPLUS_INCLUDE_PATH"
export CPATH
export C_INCLUDE_PATH
export CPLUS_INCLUDE_PATH
maybe /usr/include/clang/10/include see in you file system.
2. Second
Logout / login.
3. Third
Specifying Build Settings (Projects -> Build -> in every config build) in Build Environment section: [unset] CPATH, C_INCLUDE_PATH and CPLUS_INCLUDE_PATH
or [edit] replace this variable with the necessary values
I fixed this issue by sudo apt install clang-8.

I struggle with this for weeks now and hope someone finds this useful or knows an answer.
- I use QT 5.7 and QT 5.8 and the error occurs on both versions.
I have a QT Quick 2.0 application which I build as a dynamically linked .bundle application on a Mac using macdeployqt.
I call macdeployqt with the following parameters:
%{buildDir}/imageDatabase.app -qmldir=%{buildDir}/../UserInterface/ -always-overwrite -verbose=2
The working directory is $QTDIR/bin because macdeploy needs to be run from inside the QT-Installation directory as I learned here: https://forum.qt.io/topic/59030/solved-macdeployqt-problem/6
The following error occurs when I try to run the application:
Double-click: The app opens and the icon appears in the bar on the bottom but besides that nothing happens
Starting the app from Terminal:
Output
Machine:MacOS MyName$ ./tool
QQmlApplicationEngine failed to load component qrc:/main.qml:1 plugin cannot be
loaded for module "QtQuick": '/Users/thorstenbux/DAQRI/gitHub/artoolkit6/Source/Utilities/ImageDBSerialiser/build-ui/imageDatabase.app/Contents/PlugIns/quick/libqtquick2plugin.dylib'
is not a valid Mach-O binary (not a dynamic library)
Calling file on the library in question reveals the following
Machine:MacOS MyName$ file /Users/myname/client/gitHub/tool/SDK/Applications/tool.app/Contents/PlugIns/quick/libqtquickcontrolsplugin.dylib
/Users/myname/client/gitHub/tool/SDK/Applications/tool.app/Contents/PlugIns/quick/libqtquickcontrolsplugin.dylib: Mach-O 64-bit dSYM companion file x86_64
looks like it is loading the debug libraries.
macdeployqt error message is the following:
ERROR: Could not parse otool output: "/Users/myname/DAQRI/gitHub/tool/Source/Utilities/tool/build-tool-Desktop_Qt_5_8_0_clang_64bit-Release/tool.app/Contents/PlugIns/quick/libqtquick2plugin.dylib:\n"
Any ideas?
I finally found a solution in the QT forums. It looks like the macdeployqt has a severe bug: https://bugreports.qt.io/browse/QTBUG-57265
You need to call macdeployqt without the -always-overwrite option.
Many thanks to Andy Shaw who posted that here:

I am getting an error:
"Error occurred during initialization of VM
Unable to load native library: Can't find dependent libraries"
The error arises when I try to execute my exe file.
I have created exe file through pyinstaller on a django application. Application uses pylucine library. I think it may be the issue of error.
How to fix the error?
Since I can't be certain given you've provided very few details here is a shot in the dark to help solve your problem:
First, try removing the jvm.dll file that gets packaged with the pyinstaller -D youmodule.py command (for now work with the directory command rather than -F option). The reason why is here.
With that jvm.dll file gone, you should start seeing the actual error code - and with that the java class or dependency that isn't being loaded.
If it's a java class that isn't being properly loaded then you know instantly it must not be correcly represented in the classpath environment variable and you should do everything in your power to make sure it is:
e.g.: os.environ['CLASSPATH'] += 'the/path/to/the/jar'
Otherwise, consider bulking up your question with more details, especially if you can get a more meaningful error output.
I had the same error trying to run a .exe built with PyInstaller through wine.
My problem went away by adding C:\Program Files\Java\ [your jdk version here] \jre\bin\server to the PATH environment variable in wine - I suppose it might be the same in Windows.
It also reappeared if I tried to build with C:\Program Files\Java\ [your jdk version here] \jre\bin\server in my PATH, so I had to build without it and then append it before running it (I have no explanation as to why this happens).
I've installed Qt SDK 1.2.1, and when I'm building one of the example applications - Haptics Player, for Symbian S60, using Qt 4.7.3.
The example compiles successfully, but it fails on the Deploy step. This is the compiler output:
ERROR: Automatic patching failed at C:\QtSDK\Symbian\SDKs\Symbian1Qt473\bin\createpackage.pl line 357.
make[1]: *** [ok_sis] Error 2
C:\QtSDK\Symbian\SDKs\Symbian1Qt473\epoc32\tools\make.exe: *** [sis] Error 2
01:38:16: The process "C:\QtSDK\Symbian\SDKs\Symbian1Qt473\epoc32\tools\make.exe" exited with code 2.
Error while building project hapticsplayer (target: Symbian Device)
When executing build step 'Create SIS Package'
However, a newly created, empty project runs on my phone successfully, i.e. this error happens in the Example project that ships with Qt SDK, but not for a newly created project.
How do I fix this error?
Upon closer inspection of the compiler output, I noticed this:
Patching: Executable with capabilities incompatible with self-signing detected: "hapticsplayer_patched_caps.exe". (Incompatible capabilities: "ReadDeviceData", "WriteDeviceData".) Reducing capabilities is only supported for libraries.
Patching: Unable to patch the package for self-singing.
Use a proper developer certificate for signing this package.
Apparently, the capabilities WriteDeviceData and ReadDeviceData can't be used for self-signed packages, and require a proper developer's certificate (which is not free, and I don't have it).
Removing those lines from the .pro file fixed the problem, and Haptics Player now compiles:
symbian: {
TARGET.CAPABILITY = WriteDeviceData ReadDeviceData
}
It seems it does not really need those capabilities, I have no idea why they were added. Probably an oversight.
