Qt 6

@Persivan said in QMYSQL driver not found after release:

Any ideas?

Yes, use search function in this forum - this is asked so often.
Most probably the MySQL driver lib is missing.

Using Qt 5.15.0 MSVC2019 64bit solved the problem, so as I was using seqAn2 libs, that couldn't worked with Qt6 and also because of some windows libs....

Based on a Youtube comment this is the solution:
1- Right click on the project name and select properties.
2- Configuration properties -> General.
3- Change the "C++ Language standard" to "ISO C++17 standard".

Just a note for anyone running into this issue who happens to not need translations, the error can be bypassed by running windeployqt with the --no-translations option.

the correct answer is posted above, but a question remains: is this the most efficient method?

OK I just checked the directories and files output by the code:

QDirIterator it(":", QDirIterator::Subdirectories); while (it.hasNext()) { qDebug() << it.next(); }

and the file is stored as absolute path.

I changed the related CMake code to

qt6_add_resources(TP_ui "image" PREFIX "/image" BASE "${PROJECT_SOURCE_DIR}/image" FILES ${TP_IMAGE_FILES} )

and solved the problem.

Hi,

I think your are going to need QVideoSink.

However, I don't know how to get from your custom surface to it.

The API is being reviewed so you should check the interest mailing list and bring your porting question there.

Qt Creator does not run make install, you should probably do that manually. Hard to say exactly, looks like it's partially installed (normally it would have failed much sooner - when running qmake or cmake).

Hi,

Legitimate assumption, the new API is currently under review if memory serves well.

You should also edit charts.pro, examples.pro and the 2 CMakeLists.txt to include your project.
All other contribution guidelines still apply

Hi,

As a workaround you can either uncomment the parameter name or just remove it.

Thanks everyone who tried to help me. The thing is I didn't need dev branch content. It was enought for me to be updated with 6.2. After switching to it, everything has successfully built.
I guess, the problem was that there're some code on dev branch which doesn't pass tests.

@SGaist Done. Thanks for you help!

Thanks so much!
I have downloaded your example and started exploring how it works. I made it work by starting from a "CMakeLists.txt" created by Qt Creator. It seems to work. But I need to learn cmake, so I thank you for your example. After 30 years of programming with qmake, it takes some time to learn new things.

Create a *.so or a *.dll file Qt5 else() # add_executable(myProgram # Changed to add_library(myLib SHARED ${PROJECT_SOURCES} ) Qt6 if(${QT_VERSION_MAJOR} GREATER_EQUAL 6) # qt_add_executable(myProgram # Changed to add_library(myLib SHARED MANUAL_FINALIZATION ${PROJECT_SOURCES} Use the library file (Only tested with Qt6 and Windows) target_link_libraries (myTestProgram PRIVATE $ {PROJECT_SOURCE_DIR} /lib/myLib.dll) Or include the library file in a project that uses qmake win32:CONFIG(release, debug|release): LIBS += -L../lib/ -ldownloadunpack # Release else:win32:CONFIG(debug, debug|release): LIBS += -L../lib/ -ldownloadunpackd # Debug unix:LIBS += -ldownloadunpack

thanks a lot

@surajj4837 Hey, can you please provide your solution to this issue? Thank you ...

@polto-molto do you plan to cross-compile or just build in the device?
