Cross-platform programming of delphi

For details about delphi's cross-platform programming-General Linux technology-Linux programming and kernel, refer to the following. Since I learned linux programming, my research on delphi has been gradually reduced for many reasons, but I still miss delphi-a program that is easy to learn, powerful, and easy to write graphical interfaces. when I started to get in touch with delphi, it was also interested in cross-platform compilation, later, when I started to ACCESS linux, I realized that delphi would use kylix to implement cross-platform programming, but it was too late and kylix was almost eliminated, it is not easy to download and install kylix.

Therefore, I really want to get the cross-platform programming method of delphi, or find a good pascal compiler (program that can compile delphi) in linux. who knows this method or this compiler.
