Я интегрирую анализ cppcheck с CMake, указав следующую командную строку:
cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_CPPCHECK="cppcheck;--enable=all;--suppress=missingIncludeSystem;--inline-suppr;--std=c++17;--error-exitcode=1"
и работает хорошо.
После обновления Ubuntu с помощью cppcheck версии 2.13.0 я начал видеть это дополнительное сообщение/предупреждение :
...
[89/108] Building CXX object include/boost/multi/adaptors/fftw/test/CMakeFiles/combinations.cpp.x.dir/combinations.cpp.o
Checking /home/user/boost-multi/include/boost/multi/adaptors/fftw/test/combinations.cpp ...
nofile:0:0: information: Active checkers: 4/592 (use --checkers-report= to see details) [checkersReport]
...
Для каждой цели!
Что означает сообщение «Активные шашки: 4/592»? Почему 4?
В справке написано:
$ cppcheck --help
...
--checkers-report=
Write a report of all the active checkers to the given file.
...
Но это не помогает мне понять.
Когда я добавляю параметр --checkers-report=cppcheck.report, Я получаю следующий файл
$ cat ./.build.g++.plus/cppcheck.report
