Mini C++ debugger for Linux with basic debugging operations:

• Stepping (step in, step out, step over)
• Reading & writing variables
• Setting function/source line/memory breakpoints
• Stack unwinding
• Reading functions/lines/registers

After cloning the repository, run cmake:

cmake -DCMAKE_CXX_COMPILER="$(which clang++)" -DCMAKE_C_COMPILER="$(which clang)" -S <source_folder> -B <build_folder>

You need to compile your code in clang with the following flags to remove different optimizations: -g, -O0, -fno-omit-frame-pointer. For details, see this.

Then, simply run debugger like this:

/path/to/mdb_executable your_executable

See handleCommand function in debugger.cc for details.
