Re: The illusion of "portability"

Chris F.A. Johnson a écrit :
Note that there is objectively speaking not a single useful
program in C that can be ported to all machines that run the
language.


That's strange. I have programs that I first wrote 20 years ago on
the Amiga, that I have compiled and run successfully, without any
changes, on MS-DOS, SunOS 4, FreeBSD, NetBSD, BSDi, and GNU/Linux.

I expect they would compile and execute successfully on any
standard C implementation.


The Amiga system is not an embedded system, and it is many ways very
similar to other command line environments.

I am not telling you that portable programs do not exists or that
it is not worthwhile trying to attain some degree of independence
from the underlying system. I am telling you that (as everything)
portability has some associated COST!
