Lazarus (64-bit)

Lazarus is a cross-platform IDE for Free Pascal that works with Delphi. It comes with LCL, which works with Delphi's VCL in a way. It works on Linux, Win32, OS/2, 68K, and other systems thanks to the GPL. Free Pascal is made to be able to read and build Delphi syntax, which is object-oriented. 

Lazarus 64-bit is the last piece of the puzzle that lets you make programs that work like Delphi on all of these systems. Lazarus and Free Pascal want to be write-once, run-anywhere languages, while Java wants to be write-once, run-anywhere languages. Since all of these platforms have the same compiler, you don't have to change any of the code to make the same goods work on different platforms.

The app is being made so that it doesn't need any APIs at all. You only need to link your code to the API widget set you want after you've written it. It's great that you want to use GTK+! If you want it to work with Gnome, that's great! You can link to the widget set you want to use as long as the interface code for it is known. Well, you can write it if it's not there. 
The launcher, which has all the files it needs 

• Drag-and-drop form creator that makes it easy to make strong layouts 
• Keeping GUI forms and code in sync automatically 
• Code editor with syntax coloring and code completion that is very powerful 
• Find the Pascal source code. 
• Tools for refactoring build system and tools that work together. The IDE Open Source lets you run, test, and fix your projects. You can add to or change code and parts that are already there to fit your needs. 
• The package system lets you add third-party add-ons for more features or to make the IDE longer. 
• Several database systems to choose from to meet your needs 
• Making reports and charts 
• There are several networking tools to choose from. 
• It works with UTF8 and i18n. You should translate your work. 
• There are many more built-in programs and you can download it 

As an example. Let's say you are using the normal Windows widgets to make a product on Windows. You want to make a Linux version now. You pick out a widget set first. Let us say you want to use gtk+. To do this, you copy the code to your Linux development machine, build it, and then link it to the gtk+ units. That's it. You have now made a Linux version of the Windows offering without having to write any more code. 

As long as the code is written in standard Delphi Pascal and uses standard Delphi parts, the answer is yes. If it needs a certain database, OCX, or DCU, then the answer is no. Because these things are only for Windows, they will only work on Windows. But if all you want to do with Free Pascal and the app is make a Windows product, then the answer is yes. It's not possible yet because this hasn't been added to the LCL, but it will be soon. 

The FCL (Free Pascal Component Libraries) and the LCL (which will finally be part of the FCL) are both licensed under an LGPL that has been changed. For the most part, this means you can use these tools in your own software that you protect. If you want to sell your app, you don't have to give away or share your code. If you make changes to the FCL or LCL, though, you must share those changes with everyone, just like you did with the translator. 

Features and KeyPoints 

Cross-Platform 
It works on a lot of different systems, like Windows, macOS, Linux, and more. No matter what Raspberry Pi! These systems can also run the programs you make. You can have the same fun on your favorite OS. See Installing app for directions on how to install the app on a certain OS. 

Strong and quick 
The tool is a good IDE for working on big projects. Its compiler FPC is always being improved to make it work better. As an example of the size of a project that the IDE can handle and how well the app that it makes runs, The tool is used to make the IDE itself. 

Form Builder with Drag and Drop 
It has a graphical form creator with lines that show how to line up components next to each other. A lot of parts for almost any software you can think of are already prepared to be used. With Package Files (LPKs), you can add more parts to the IDE. 

Cross-platform 
The app form creator uses LCL, which stands for "Lazarus Component Library." This library was made to work on multiple platforms. It will look and feel like it was made for each platform if you build your project for more than one. The idea doesn't need any changes. 

Modern language that is object-oriented 
Its language is Free Pascal, which is a type of Object Pascal. It is being improved all the time to add new features that are common in current programming languages. 

Easy to add on to 
Libraries and Packages (LPKs) are made and kept up to date by hundreds of writers. You can find almost any kind of library you might need.
