Qt 6 adding qt_add_translations() to CMake creates empty .ts files.

[Vede34]

I've been attempting to add support for localization to a project. From the documentation I understand the following CMake should create the template for my .ts filled with the text variables I marked with qsTr("example"). However, it only seems to create an empty .ts file.

How could I approach fixing this problem?

The following is a recreation in a test project with simpler files.
main.qml

import QtQuick

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
}

CMakeLists.txt

cmake_minimum_required(VERSION 3.16)

project(translatetest VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 6.2 COMPONENTS Quick LinguistTools REQUIRED)

qt_add_executable(apptranslatetest
    main.cpp
)

qt_add_qml_module(apptranslatetest
    URI translatetest
    VERSION 1.0
    QML_FILES main.qml 
)

qt_add_translations(apptranslatetest
    TS_FILES
        translatetest_fi_FI.ts
)

set_target_properties(apptranslatetest PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

target_link_libraries(apptranslatetest
    PRIVATE Qt6::Quick)

install(TARGETS apptranslatetest
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR})

After building and running:
translatetest_fi_FI.ts

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS>
<TS version="2.1" language="fi_FI"></TS>

Hi

I was having the same issue.

Seems like in Qtcreator and CMAKE, the target "all" does not include update_translations target.

Just go to project check it and it will be generated

@ikerssm Thank you I would never have come to a solution If I hadn't read this. Such a dumb bug.

Nice to see that problem is still there using QtCreator 17.0!!!

Thanks for the solution, it helped me saving extra time (already spent 5 hours with AIs involved as well)

Best solution, independent from changing the targets manually, is to add:
add_dependencies(${PROJECT_NAME} update_translations)
