C++ lcov reached unexpected end of file

Question

I try to create a coverage report. I use

make clean all and make coverage .

I have Boost and lcov installed. But when I try make coverage it fails with the following error message:

Processing components/Project/CMakeFiles/ProjectMainController.dir/dataHandling/savingUnit/Trimmer.cpp.gcda
geninfo: ERROR: /home/user/ProjectFolder/Project/build/source/Project/components/Project/CMakeFiles/ProjectMainController.dir/dataHandling/savingUnit/Trimmer.cpp.gcno: reached unexpected end of file
make[3]: *** [CMakeFiles/coverage] Error 255
make[2]: *** [CMakeFiles/coverage.dir/all] Error 2
make[1]: *** [CMakeFiles/coverage.dir/rule] Error 2

The strange part is: I havent even written any tests for the Trimmer class and there isnt even a TrimmerTest file. Can you help me?
