The closest supported equivalent to Kylix is the free Lazarus IDE package, designed to be code-compatible with Delphi.
The IDE makes it easy to select components and place them on a form, editing properties and event handlers with an "Object Inspector".
As such, VCL is tightly bound to Windows, and Kylix's CLX is built on top of Trolltech's Qt library.
CLX is not 100% compatible with VCL, and most Delphi programs require some effort to port to Kylix, even if they stick to the Borland libraries and avoid any direct OS calls.
[3] On March 24, 2000, Inprise/Borland Corporation hosted more than 200 third-party authors, consultants, trainers and tool and component vendors for the first in a series of worldwide events designed to prepare third party products and services for Kylix.
[citation needed] While both Delphi and Kylix run on 32-bit Intel processors, Linux uses different register conventions than Windows and, of course, the executable and library file formats are different; see DLL, EXE, ELF for details.
In 8 Feb 2016, Embarcadero Technologies, Inc. announced an updated roadmap that indicates Linux server support in upcoming RAD Studio 10.2 (code name "Godzilla") development track, aka the Fall release.
