qt5_create_translation does not update .ts

Sauntor

When using cmake to build qt5 project on openSUSE tumbleweed(qt 5.15.11), the cmake command qt5_create_translation and qt5_add_translation does nothing, they do not update .ts and do not genrate .qm .
What's wrong?

Christian Ehrlicher

How do you use them? Please show your CMakeLists.txt.
And do you really use Qt5?

@Christian-Ehrlicher
CMakeLists.txt https://paste.opensuse.org/pastes/3b20e7f51bbd
main.cpp https://paste.opensuse.org/pastes/f3f943334115
The demo project has this two files only. I open this project with qtcreator and configure it with Qt5 Kits

And if you add message("lupdate = ${Qt5_LUPDATE_EXECUTABLE}") to CMakeLists.txt, it will show something like Qt5:lupdate, that's may be the real cause

No, that's correct.

qt_create_translation(QM_FILES ${CMAKE_SOURCE_DIR} ${TS_FILES})

You don't do anything with the qm files so nothing will happen. You have to add them to a target.

But I would not use deprecated functions but qt_add_translations()

Sauntor

@Christian-Ehrlicher Qt5's cmake modules does not provide the qt_add_translations() command, it's added in Qt6.

qt5_create_translation() does not generate a cmake target, so, how to add it to my executable target?

PS:
If you run lupdate CMakeLists.txt, it will output something like lupdate warning: no TS files specified. Only diagnostics will be produced. . Is it the problem? Or we can say that qt5_create_translation() depends on the qmake project file(.pro)?

The same way you added the ts files in your add_executable call.

Don't know why you don't use the new macros since you use Qt6 in your provided example though.

Sauntor

@Christian-Ehrlicher it already in:

add_executable(tsdemo
  main.cpp
  ${TS_FILES}
  images.qrc
)

I'm try compile my project with qt5 only, so the new macros are not avaliable.
