Welcome to Lazarus

Lazarus is a Rapid Application Development Tool for Free Pascal.
It comes with the LCL - Lazarus component library, which contains platform
independent visual components like buttons, windows, checkbox, treeview and
many, many more. The LCL is platform independent, so you can write an
application once and then compile for various platforms without changing code.

Free Pascal is a fast Object Pascal compiler,
that runs on more than 20 platforms (Linux, Windows, BSD, OS/2, DOS, PowerPC,
and many more).

The LCL currently supports:
* Linux/FreeBSD (GTK2, Qt4, Qt5 and Qt6)
* all flavors of Windows (even WinCE)
* macOS (Cocoa, Carbon, GTK2, Qt4, Qt5, Qt6)

There is an experimental support for:
* GTK3
* Solaris

The LCL still contains code for GTK1, although this target is obsolete.

Compilation

You don't need ./configure, just do
make clean bigide (gmake clean bigide in BSD).

This will create the Lazarus executable with a lot of packages.
Start it and enjoy.

If the above gives an error, you can try to build a minimal IDE with
make clean all (gmake clean all in BSD).

Installation and Requirements

See Lazarus Wiki for details.

Usage

Start the IDE with:

cd your/lazarus/directory
./lazarus

Documentation

The official site is www.lazarus-ide.org.
Documents about specific topics can be found at
https://wiki.freepascal.org/Lazarus_Documentation.
Examples on how to use the LCL can be found in the examples directory.
Help, documents and files about Free Pascal are at www.freepascal.org.

Mailing list

There is a very active and helpful mailing list for Lazarus, where the
developers interact, share ideas, discuss problems, and of course answer
questions.
You can subscribe at
http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus.

How to help Lazarus

If you find bugs, don't hesitate to use issue tracker,
