Oh dear: the problem also occurs on macOS 10.14 "Mojave", with a simple "Qt Widgets application" (as generated from scratch by Qt Creator, with a single QMainWindow and a translation file (as added by the "New project" wizard using Cmake): 19:42:58: Führe Schritte für Projekt MainWindow aus... 19:42:58: Starte: "/Users/tknoll/Qt/Tools/CMake/CMake.app/Contents/bin/cmake" --build . --target all [1/5 13.6/sec] Generating /Users/tknoll/resources/work/Qt/MainWindow/MainWindow_de_DE.ts FAILED: /Users/tknoll/resources/work/Qt/MainWindow/MainWindow_de_DE.ts CMakeFiles/MainWindow_de_DE.ts_lst_file cd /Users/tknoll/resources/work/Qt/build-MainWindow-Desktop_Qt_5_15_2_clang_64bit-Debug && /Users/tknoll/Qt/5.15.2/clang_64/bin/lupdate @/Users/tknoll/resources/work/Qt/build-MainWindow-Desktop_Qt_5_15_2_clang_64bit-Debug/CMakeFiles/MainWindow_de_DE.ts_lst_file -ts /Users/tknoll/resources/work/Qt/MainWindow/MainWindow_de_DE.ts lupdate error: List file '/Users/tknoll/resources/work/Qt/build-MainWindow-Desktop_Qt_5_15_2_clang_64bit-Debug/CMakeFiles/MainWindow_de_DE.ts_lst_file' is not readable. ninja: build stopped: subcommand failed. 19:42:58: Der Prozess "/Users/tknoll/Qt/Tools/CMake/CMake.app/Contents/bin/cmake" wurde mit dem Rückgabewert 1 beendet.

In fact - unlike as on Windows 10 - I can delete the entire build-MainWindow-Desktop_Qt_5_15_2_clang_64bit-Debug folder without problems. Of at this point there is no MainWindow_de_DE.ts_lst_file in that directory: $> ls -la total 64 drwxr-xr-x 11 tknoll staff 352 5 Jan 19:51 . drwxr-xr-x 11 tknoll staff 352 5 Jan 19:51 .. drwxr-xr-x 6 tknoll staff 192 5 Jan 19:51 3.19.0 -rw-r--r-- 1 tknoll staff 15382 5 Jan 19:51 CMakeOutput.log drwxr-xr-x 2 tknoll staff 64 5 Jan 19:51 CMakeTmp drwxr-xr-x 3 tknoll staff 96 5 Jan 19:51 MainWindow.dir drwxr-xr-x 5 tknoll staff 160 5 Jan 19:51 MainWindow_autogen.dir -rw-r--r-- 1 tknoll staff 589 5 Jan 19:51 TargetDirectories.txt -rw-r--r-- 1 tknoll staff 287 5 Jan 19:51 clean_additional.cmake -rw-r--r-- 1 tknoll staff 85 5 Jan 19:51 cmake.check_cache -rw-r--r-- 1 tknoll staff 2415 5 Jan 19:51 rules.ninja That explains the "not readable" (follow-up) error message then. Or in other words: the generated CMakeLists.txt (generated by Qt Creator 4.14.0) simply does not work, neither on Windows nor on macOS (at least not on Mojave". There is no other cmake in the PATH (I specifically uninstalled an older version with "brew uninstall cmake". In fact, there is no cmake at all in the PATH right now (I am exclusively building from within Qt Creator for the time being). Now at this point, if I do: * Clear CMake configuration * Run CMake and build again (with CTRL / CMD + B) then it works with the translation file: 20:00:54: Running steps for project MainWindow... 20:00:54: Starting: "/Users/tknoll/Qt/Tools/CMake/CMake.app/Contents/bin/cmake" --build . --target all [1/6 2.5/sec] Automatic MOC and UIC for target MainWindow [2/6 4.4/sec] Generating /Users/tknoll/resources/work/Qt/MainWindow/MainWindow_de_DE.ts Scanning directory '/Users/tknoll/resources/work/Qt/MainWindow'...

Undefined symbols for architecture x86_64: "std::terminate()", referenced from: ___clang_call_terminate in MainWindow.cpp.o (etc.) It turns out that an added target_link_options(MainWindow PRIVATE -lc++) links against the - apparently "forgotten" - C++ library and the application links and runs properly. I have also looked at the above issue by now, which seems to be a problem with CMake projects also deleting the *.ts files when doing a "clean project". So there might be some connection... All this leaves me think that the whole CMake integration is still a big construction site, at least as far as Qt 5.15.2 and latest Qt Creator is concerned (btw the reaons why I stayed with Qt 5.15 for now - and not Qt 6 - is because I wanted to keep "the numbers of unknowns low". The new "unknown" being CMake for me obviously). Does anyone have more luck with CMake, at least with Qt 6 perhaps? It seems I have to dig into the CMake documentation more closely than I intended to after all and apply all the *tricks with CMake and Qt* spread all over the Internet *sigh*... ;) Thanks, Oliver
