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, Gtk3, Qt4, Qt5, Qt6)
- all flavors of Windows (even WinCE)
- macOS (Cocoa, Carbon, Gtk2, Qt4, Qt5, Qt6)
The LCL still contains code for Gtk1 (although this target is obsolete).
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).
See Lazarus Wiki for details.
Start the IDE with:
cd your/lazarus/directory
./lazarusThe 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.
There are very active and helpful forum and mailing list for Lazarus, where the developers interact, share ideas, discuss problems, and of course answer questions.
You can subscribe to mailing list at http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus.
Forum is available at https://forum.lazarus.freepascal.org/.
If you find bugs, don't hesitate to use issue tracker, or send an email to the list. Lazarus source code and issue tracker are located at GitLab.
