Arch does package qtcreator-devel. See https://archlinux.org/packages/extra/x86_64/qtcreator-devel/

I looked these but, I could not understand anything. I need some example

@jsulm said in Add external library Cmake Windows:

Do you also have the *.lib files for these libs there? You can't link *.dll files, for linking you need *.lib.

Yes I have all files

Instead of closing the console window you could compile without the /CONSOLE flag and then use AttachConsole in the case of the non-gui application.

We are actually using a two-application solution which is a little different than a launcher script. This solution is taken from Microsoft itself. Visual Studio comes as a devenv.exe and a devenv.com. The .exe is the GUI application and the .com is the command line application. On the command line (when using the application name without the file ending) it will start the .com application. In our own application we added command line parameters to have each call the other one (using QProcess) to switch between GUI/non-GUI.

It was in typing the original question that I thought "what does QtCreator do"? - and got the command line from there

I use cmake on VS 2022, but I'm not an expert. It feels very beta-ish. When something does not work, I try one of the two:

Restart VS2022 Make a cmake build into the same build folder using Qt Creator. That updates CMakeCache.txt, and suddenly VS2022 knows what to do.

Unfortunately, I don't have a deeper understanding of what's going on here...

@jsulm thanks!

I just added

target_include_directories(<appName> PUBLIC src)

what works well.

@KK2022 You should also add header files. Building will work without I think, but QtCreator will not find the header files I guess and complain.

@Futuray-Programming That's what WebEngine is made for.

@PerssonBrown said in CMake can NOT find Vulkan when building:

Here are my questions:

What is Vulkan?

It is a library for displaying graphics, much like OpenGL, DirectX or Metal.

Do all Widget Applications need Vulkan?

No, you can safely ignore this warning. When Vulkan is not present, Qt will use other libraries to draw stuff.

How to fix this missing warning?

On Windows I'm not sure if you can fix it, but you can ignore it.

@lucast

Thanks, indeed it aligns better with the new design.
I will try to use loadFromModule API from now on
According to this will improve compilation time when changing qml files, that is something I was looking for.

You could use CMakePresets.json file to specify a CMake Preset Kit.

Qt Creator would then use the information from the CMakePresets.json file and create a kit for you.

Something like:

{ "version": 4 }, "configurePresets": [ { "name": "arm-gnu-toolchain", "displayName": "Arm GNU GCC 13.2", "generator": "Ninja", "toolchainFile" : "C:/arm-gnu-toolchain-13.2/toolchain.cmake", "cacheVariables": { "CMAKE_C_COMPILER": "arm-none-eabi-gcc.exe", "CMAKE_CXX_COMPILER": "arm-none-eabi-g++.exe" } } ] }

See https://doc.qt.io/qtcreator/creator-build-settings-cmake-presets.html and various Qt Creator CMake blog entries for more details.

hey that is really helpful but
i want to ask can some one guide me building Quazip and Zlib by Qt creator in build Cmake
i don't want to download separate Cmake and perform all these commands in it
i tried to do this and i guess i was partially succesfull

i got this Msg in my application output while running Zlib
zlib version 1.3.1 = 0x1310, compile flags = 0x65
uncompress(): hello, hello!
gzread(): hello, hello!
gzgets() after gzseek: hello!
inflate(): hello, hello!
large_inflate(): OK
after inflateSync(): hello, hello!
inflate with dictionary: hello, hello!

and i found these files in my build folder = libzlib.dll
libzlib.dll.a
and other files
but when i tried to build Quazip it did not gone as planed i got so many errors
so can someone pls give its answer too i really appreciate that.

@kkoehne said in CMake +Qt6 +lupdate:
cool - sounds to become easier and more flexible in 6.7. will test with beta2

And the NATIVE_TS_FILE option only will actually appear in Qt 6.7: https://doc-snapshots.qt.io/qt6-dev/qtlinguist-cmake-qt-add-translations.html

I'm developing always in english, where in most cases german is used by customers. Because I'm writing code in 'developer-english' it may happen, that customer requests to change a translation. for these cases and to handle plural forms I always also add an en ts file, so I'm using
.ts / _de.ts / _en.ts / _fr.ts ...
this is working well because translations not found in _en.ts will come from .ts
seems that in this case I don't have to set the NATIVE_TS_FILE, because _en.ts not only contains plural forms ?

if setting QT_I18N_LANGUAGES will this work if my (from Qt 5.15 ported) .ts files are in project_dir/translations ?

BTW: the lrelease command is executed automatically if building in QtCreator ?
In 5.15 my workflow was: lupdate, Linguist, lrelease
Now in 6.7 I can do lupdate automatically with add_dependencies(...lupdate) or execute manually with CMD-K cm ...lupdate and lrelease is always done automagically ?

I just realized that Qt6 is not tested against tvOS specifically and is built against iOS. The latter has wider selection of available frameworks.

I guess I'll need to manually Qt for tvOS.
