CMake set_source_files_properties error

[SGaist]

Hi,

Based on the arrowpad example, it looks like you are not setting everything properly.

[ekkescorner]

@Teg-Miles take a look at my posts about translations https://t1p.de/ekkeCMakeTranslation
you're missing set_source_files_properties...

[Teg Miles]

qt_add_translations() doesn't work as it described in Qt6 tutorial.
I changed it to:

qt_add_lrelease(TS_FILES
    i18n/Movar_cpp_en_US.ts
    i18n/Movar_cpp_ja_JP.ts
    i18n/Movar_cpp_uk_UA.ts
)

and the translations work fine now.

[ekkescorner]

what is your Qt version ?

[Teg Miles]

@ekkescorner 6.7.0

[ekkescorner]

for me it works perfect without in Qt 6.7
but I set the languages in qt_standard_project_setup, which is recommended with 6.7+
see also https://www.qt.io/blog/revisited-i18n-with-cmake

@ekkescorner It doesn't work either for me. And then I wrote en_US, uk_UA, ja_JP in I18N_TRANSLATED_LANGUAGES arguments it creates _en.ts files anyway. Is there some inbuilt settings for English language?

[ekkescorner]

I know the default SOURCE language is en
do you mean you get en_US AND en ?
this would be OK if your development-language (SOURCE) is en
then as default qt_add_translations will use en for development, also creates a special en for plurals only plus all TRANSLATED languages

in my apps where en is my SOURCE language I want to have all translated also in en, so I set NO_GENERATE_PLURALS_TS_FILE

[Teg Miles]

@ekkescorner I found in yours article solution for fixing en_US and en simultaneous ts files creation:

qt_standard_project_setup(
    I18N_SOURCE_LANGUAGE en_US
    I18N_TRANSLATED_LANGUAGES uk_UA ja_JP
)

Finally I created CMakeLists that works for me:

cmake_minimum_required(VERSION 3.5)

project(Movar_cpp VERSION 1.0.2 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

find_package(Qt6 REQUIRED COMPONENTS Widgets
    LinguistTools WebEngineWidgets TextToSpeech)
qt_standard_project_setup()

qt_add_lupdate(
    TS_FILES
    translations/Movar_cpp_en_US.ts
    translations/Movar_cpp_ja_JP.ts
    translations/Movar_cpp_uk_UA.ts

    SOURCES
    mainwindow.cpp
    dictionarysettings.cpp
    fileloader.cpp
    mainwindow.ui
    dictionarysettings.ui
)

qt_add_lrelease(
    TS_FILES
    translations/Movar_cpp_en_US.ts
    translations/Movar_cpp_ja_JP.ts
    translations/Movar_cpp_uk_UA.ts
)

qt_add_executable(Movar_cpp
    mainwindow.ui
    mainwindow.h
    mainwindow.cpp
    main.cpp
    dictionarysettings.h
    dictionarysettings.cpp
    dictionarysettings.ui
    fileloader.h
    fileloader.cpp
    app_resources.qrc
    adaptedcompleter.h
    adaptedcompleter.cpp
    adaptedstringlistmodel.h
    adaptedstringlistmodel.cpp
)

add_dependencies(${CMAKE_PROJECT_NAME} update_translations)

target_link_libraries(Movar_cpp PRIVATE
    Qt6::Widgets
    Qt6::WebEngineWidgets
    Qt6::TextToSpeech)

set_target_properties(Movar_cpp PROPERTIES
    WIN32_EXECUTABLE ON
)

install(TARGETS Movar_cpp
    BUNDLE  DESTINATION .
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}

)

I used qt_add_lupdate and qt_add_lrelease.
And there must be added function add_dependencies().
As I understand, it's old bug with lacking "update_translations" in beforementioned functions.
Without it ts files will be empty.

[ekkescorner]

curios. but good to hear that you found a working solution.
