Fully agreed! Adding a good POSIX.5 binding with man pages to the GNAT distribution should help a lot to make Ada an attractive system programming language for Unix systems. > 1) Anyone willing to do such a binding will first have > to spend money on buying a standard; Expensive paper-only standards are a real hazzle for non-commercial (academic) users.

And as a consequence, not much portable system programming for Unix in Ada seems to be going on at the moment and GNAT seems to be mostly used for teaching the language since C development environments still provide a much richer API at the moment and every Ada developer has to first come up with his private subet binding to the C libraries before he can start with the actual project.

Some customers have indeed been interested in a Posix interface, which is why we are working with Ted Baker's team at FSU to integrate Florist with the GNAT release. However, in our experience there are many users of GNAT under Unix who prefer to use pragma Import to get at whatever facilities they need, or who are using other bindings. The demand for a Posix interface is by no means as universal as Markus seems to think it is. Of course I understand the "if only Ada 95 provided XXX, then all the world would flock from C/C++ to Ada 95." I look on all such claims with what the US Secretary of Defence called an "Ohio attitude", namely I won't be convinced till I see some evidence that such a claim is true :-) Robert Dewar Ada Core Technologies ^ permalink raw reply [flat|nested] 4+ messages in thread

I must be culturally unsophisticated or something, but I thought that particular weltanschauung was a characteristic of the "show me" state. Which Ohio reference am I missing here? Also, if Ada 95 provided XXX, we'd be within our rights to spam the world with "ADULTS ONLY: Ada 95 does XXX!!!" :-) -- Brian ^ permalink raw reply [flat|nested] 4+ messages in thread
