Problem linking on Linux using CMake

Perdrix

I'm getting these errors from the link step when I try to build using CMake (Qt 6.8.0):

/usr/bin/ld: DeepSkyStacker/CMakeFiles/DeepSkyStacker.dir/DeepSkyStacker_autogen/4COPAEF2SH/qrc_DeepSkyStacker_translations.cpp.o (symbol from plugin): in function `qInitResources_DeepSkyStacker_translations()':
(.text+0x0): multiple definition of `qInitResources_DeepSkyStacker_translations()'; DeepSkyStacker/CMakeFiles/DeepSkyStacker.dir/__/.qt/rcc/qrc_DeepSkyStacker_translations.cpp.o (symbol from plugin):(.text+0x0): first defined here
/usr/bin/ld: DeepSkyStacker/CMakeFiles/DeepSkyStacker.dir/DeepSkyStacker_autogen/4COPAEF2SH/qrc_DeepSkyStacker_translations.cpp.o (symbol from plugin): in function `qInitResources_DeepSkyStacker_translations()':
(.text+0x0): multiple definition of `qCleanupResources_DeepSkyStacker_translations()'; DeepSkyStacker/CMakeFiles/DeepSkyStacker.dir/__/.qt/rcc/qrc_DeepSkyStacker_translations.cpp.o (symbol from plugin):(.text+0x0): first defined here

In my CMakeLists.txt I have:

qt_add_executable(DeepSkyStacker ${ALL_FILES})
qt_standard_project_setup(I18N_TRANSLATED_LANGUAGES ca cs de es fr it ja_JP nl pt_BR ro ru tr zh_CN zh_TW)
qt_add_translations(${PROJECT_NAME} PLURALS_TS_FILE en TS_FILE_DIR i18n)

During the build I see:

119/168] Automatic MOC and UIC for target DeepSkyStacker
[120/168] Automatic RCC for resources.qrc
[121/168] Automatic RCC for ../.qt/rcc/DeepSkyStacker_translations.qrc
[122/168] Building CXX object DeepSkyStacker/CMakeFiles/DeepSkyStacker.dir/__/.qt/rcc/qrc_DeepSkyStacker_translations.cpp.o

[167/168] Building CXX object DeepSkyStacker/CMakeFiles/DeepSkyStacker.dir/DeepSkyStacker_autogen/EWIEGA46WW/qrc_resources.cpp.o

So it looks like it is generating TWO qrc files for the translation files? !!!

I can post the full CMakeLists.txt file if needed but it's not small ...

Maybe you have some function definition in a header file or you're including the same translation unit multiple times in your build target's sources.

None of the above

Removing setting of CMAKE_AUTORCC fixed this
