Laboratory work XV

Данная лабораторная работа посвещена изучению инструментов статического и динамического анализа кода

$ open http://cppcheck.sourceforge.net

Tasks

  • 1. Ознакомиться со ссылками учебного материала
  • 2. Используя cpplint провести анализ проекта на C++
  • 3. Используя Cppcheck провести анализ проекта на C++
  • 4. Используя OCLint провести анализ проекта на C++
  • 5. Используя Valgrind провести анализ проекта на C++
  • 6. Составить отчет и отправить ссылку личным сообщением в Slack

Tutorial

Копируем репозиторий в директорию lab15

$ git clone https://github.com/${GITHUB_USERNAME}/Labs lab15
$ cd lab15
$ git checkout lab13
$ cmake -H. -B_build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=_install -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
$ cmake --build _build
$ cmake --build _build --target install

Устанавливаем cpplint

$ sudo apt-get install python-pip
$ pip install cpplint

Производим анализ проекта используя cpplint

$ cpplint source/demo.cpp
/sources/demo.cpp:0:  No copyright message found.  You should have a line: "Copyright [year] <Copyright Owner>"  [legal/copyright] [5]
/sources/demo.cpp:2:  Found C++ system header after other header. Should be: demo.h, c system, c++ system, other.  [build/include_order] [4]
/sources/demo.cpp:5:  Static/global string variables are not permitted.  [runtime/string] [4]
/sources/demo.cpp:6:  Static/global string variables are not permitted.  [runtime/string] [4]
Done processing lab15/sources/demo.cpp
Total errors found: 4

Устанавливаем Cppcheck

$ sudo apt-get install cppcheck

Производим анализ проекта используя Cppcheck

$ cppcheck --enable=all --inconclusive --check-config --std=c++11 sources/demo.cpp
Checking sources/demo.cpp ...
[sources/demo.cpp:1]: (information) Include file: <print.hpp> not found. Please note: Cppcheck does not need standard library headers to get proper results.
[sources/demo.cpp:2]: (information) Include file: <cstdlib> not found. Please note: Cppcheck does not need standard library headers to get proper results.

Устанавливаем OCLint

$ wget https://github.com/oclint/oclint/releases/download/v0.13.1/oclint-0.13.1-x86_64-linux-4.4.0-112-generic.tar.gz
$ tar -xzvf oclint-0.13.1-x86_64-linux-4.4.0-112-generic.tar.gz 
$ rm -rf oclint-0.13.1-x86_64-linux-4.4.0-112-generic.tar.gz
$ export OCLINT_HOME=`pwd`/oclint-0.13.1/bin/oclint/oclint-0.13.1
$ export PATH=$OCLINT_HOME/bin:$PATH

Производим анализ проекта используя OCLint

$ oclint -p=_build sources/demo.cpp
