You've now just created a Linux version of the Windows product without any additional coding.Īt this point in the development we are using Win32, gtk+, Carbon and QT as our API widget set. So you copy the code over to your Linux development machine, compile, and link against the gtk+ interface unit. First you decide what widget set you want to use. Let's say you are creating a product on Windows using the standard Windows widgets. If it isn't available, well you can write it.įor example. If you want to use GTK+, great! If you want it to be Gnome compliant, great! As long as the interface code for the widget set you want to use is available you can link to it. Once you write your code you just link it against the API widget set of your choice. Lazarus is being developed to be totally and completely API independent. Yeah, but what about the GUI? What widget set are you using? Since the exact same compiler is available on all of the above platforms it means you don't need to do any recoding to produce identical products for different platforms. Unlike Java which strives to be a write once run anywhere, Lazarus and Free Pascal strives for write once compile anywhere. Lazarus is the part of the missing puzzle that will allow you to develop Delphi like programs in all of the above platforms. Free Pascal is designed to be able to understand and compile Delphi syntax, which is of course OOP. Free Pascal is a GPL'ed compiler that runs on Linux, Win32, OS/2, 68K and more. Lazarus is the class libraries for Free Pascal that emulate Delphi.
