How to Build and Run

Prerequisites

1. C++ Compiler: A modern C++ compiler (like GCC, Clang, or MSVC) that supports C++17.
2. CMake: Version 3.10 or higher.
3. SQLite3 Development Library:
   • On Debian/Ubuntu: sudo apt-get install build-essential cmake libsqlite3-dev
   • On Fedora/CentOS: sudo dnf install cmake make gcc-c++ sqlite-devel
   • On macOS (with Homebrew): brew install cmake sqlite3

Build Steps

1. Place all the source files (.cpp, .h, CMakeLists.txt) in your project directory.

2. Open a terminal in your project directory and run the following commands:

   # Create a separate directory for build files
   mkdir build
   cd build
   
   # Configure the project with CMake
   cmake ..
   
   # Compile the source code
   make

Run the Application

After a successful build, an executable named library_backend (or library_backend.exe on Windows) will be created in the build directory. Run it from your main project directory:

# Go back to the main project directory from 'build'
cd ..

# Run the executable
./build/library_backend
