cmake g++ address sanitizer

Certainly! Here's a step-by-step guide to using CMake with g++ and AddressSanitizer:

  1. Install Required Software: Ensure CMake and g++ are installed on your system. You might need to install AddressSanitizer separately depending on your setup.

  2. Create a CMakeLists.txt File: Create a CMakeLists.txt file in your project directory. This file contains instructions for building your project with CMake.

  3. Enable AddressSanitizer: Modify your CMakeLists.txt to enable AddressSanitizer. Add the following lines: cmake # Enable AddressSanitizer set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fsanitize=address -fno-omit-frame-pointer")

  4. Specify Debug Build Type: To ensure AddressSanitizer works correctly, specify the build type as Debug in your CMakeLists.txt: cmake set(CMAKE_BUILD_TYPE "Debug")

  5. Configure and Generate Build Files: Run CMake to generate build files. Open a terminal in your project directory and execute: bash cmake -S . -B build

  6. Build the Project: Navigate to the build directory and compile your project using g++: bash cmake --build build

  7. Run the AddressSanitizer: Execute your compiled program with AddressSanitizer enabled: bash ASAN_OPTIONS=detect_leaks=1 ./your_executable

Replace your_executable with the name of your compiled executable file.

  1. Analyze AddressSanitizer Output: AddressSanitizer will provide reports if it detects any memory errors during the program's execution. Review these reports to identify and fix issues in your code.

  2. Fix Errors and Rebuild: Make necessary code changes based on AddressSanitizer's reports, then rebuild your project using the same procedure.

  3. Repeat Analysis: Run the program again with AddressSanitizer to ensure that the reported issues have been resolved.

Remember, the steps might slightly differ based on your project structure or specific requirements. Adjust the settings accordingly for your use case.
