I don't think FPC would exist if that was the case.
and why is delphi not made in delphi?
Quote from: korba812 on February 19, 2017, 02:32:33 pmand why is delphi not made in delphi?Actually Delphi as an IDE is written in Delphi. But the Delphi object pascal compiler is - depending on the version - written in C and assembler or C++.
So, obviously, as a matter of choice, anyone can use any compiler and any IDE to build any new compiler or any new IDE.
