They produced Kylix not that long ago - I had an original box set once upon a time. I have no idea why that didn't take off, but it was an excellent environment really.
To clarify: dependency on wine means that the IDE was essentially windows application (stripped-down delphi) running on top of wine . Wine was not required for deployment of applications.
Kylix was doomed from day one; I saw an official presentation (IIRC by Marco Cantù himself) ages ago and was shocked by its slugginess. At that time I was playing with Delphi2 at home and using Delphi 4 at work, and both of them literally run circles around Kylix.
Today Delphi on Linux to me is called Lazarus. Some nasty bugs plaguing it are long gone since like 3 years and is very stable at the moment. You can even install it on a ARM based board (Orange PI PC here) which means it doesn't simply cross compile the code but the IDE itself runs on ARM architecture!
