LibSys (Library Management System Software)

LibSys, LibSys Installer, LibSys Updater © 2026 – Habil Eren Türker

About the Project

LibSys is an open-source library management system written in C++ that handles book borrow operations, user management, and catalog operations.

⚠️ Attention: This project is still under test. You may encounter bugs and crashes. I, Habil Eren Türker, created this open-source project for educational purposes. My main goal during the development of this project was creating a software which my school (Çemberlitaş Anatolian High School) can use in its library. You need .dll files to run these programs. You can find them in LibSysPackage.zip in releases.

Features

• Book management (add, remove, update)
• User management (add member, remove member, update member info)
• Borrow and return operations
• Basic search and filtering functionality
• Modular and extensible architecture
• User-friendly GUI
• RFID support

Technology & Structure

• Programming Language: C++
• Build system: CMake + Makefile
• License: GNU GPL v3.0 (License)

Installation

If you are using Windows, you must install mingw-w64/MSYS2 and tools G++, CMake and Makefile. Also you must install Qt Framework (Version at least 6.10.0).

You can find more information here: (Qt) (MSYS2) (mingw-w64)

Also you must change all CMakeLists.txt files'

set(CMAKE_PREFIX_PATH "C:/Qt/6.10.2/mingw_64")

part with the path you have Qt installed.

Follow the steps below to run the project on your machine:

git clone https://github.com/herenturker/LibSys.git  
cd LibSys  
mkdir project && cd project  
make build # Create CMake build files. If you want to build files a seperate, run make <program_name>. Example: make LibSys
./LibSys   # or the generated executable name

Usage

See (Usage) When you run LibSys, program would create databases directory with databases/users.db and databases/library.db and a log.log in program directory.

Do not delete these files.

Contributing

Contributions are welcome! Please follow these steps:

• Fork the repository and create your branch.
• Commit and push your changes.
• Open a pull request.
• Ensure your code is tested and readable.

Testing

Manual testing scenarios:

• Add a new book → should appear in the database
• Add a new member → should be able to borrow books
• Lend a book → member and book status updated
• Return a book → lending status reset
