GNU/Linux Ubuntu 20.04 Installing Lazarus IDE – QuickStart Guide
Hi! The Tutorial shows you Step-by-Step How to Install Lazarus IDE in Ubuntu 20.04 Focal LTS GNU/Linux Desktop.
And Lazarus IDE for Object-Pascal/Delphi is a Free Cross-Platform visual Integrated Development Environment (IDE) for Rapid Application Development (RAD) using the Free Pascal Compiler, which supports Dialects of Object Pascal, to varying Degrees.
Moreover, the Software Developers use Lazarus to Create Native-Code Console and Graphical User interface (GUI) Apps for the Desktop, and also for Mobile Devices, Web Apps, Web Services, Visual Components and Function Libraries (.so, .dll, etc., for use by other programs).
Here are some Key Features of Lazarus IDE:
- Cross-Platform Development: Lazarus allows developers to write code once and compile it for multiple platforms without significant modifications. This is facilitated by Free Pascal’s support for various operating systems and CPU architectures.
- Component-Based Development: Lazarus follows a component-based approach, where developers can design user interfaces and functionality by assembling pre-built visual and non-visual components. This accelerates the development process and promotes code reusability.
- Integrated Debugger: Lazarus includes an integrated debugger that enables developers to debug their applications efficiently. This debugger supports features such as breakpoints, watchlists, and call stacks, helping developers to identify and fix issues in their code.
- Extensive Component Library: Lazarus comes with a vast array of components for building graphical user interfaces (GUIs), database applications, networking applications, and more. These components provide ready-made solutions for common programming tasks, saving developers time and effort.
- Open Source: Lazarus is an open-source project released under the GNU General Public License (GPL). This means that developers have access to the full source code of the IDE and can modify it to suit their specific requirements.
- Active Community: Lazarus has a vibrant and supportive community of developers and users who contribute to its development, provide assistance on forums and mailing lists, and share knowledge and resources.
- Compatibility with Delphi: Lazarus aims for compatibility with Delphi, another popular IDE and programming language for Windows development. This compatibility allows developers with experience in Delphi to transition smoothly to Lazarus.
Finally, the guide includes detailed instruction on How to Getting-Started with Free Pascal Development on Lazarus for Ubuntu.
