Gnat Error: intrinsic operator can only apply to numeric types

Gnat Error: intrinsic operator can only apply to numeric types

[Marin David Condic]

In using Gnat 3.15p on Windows with GPS v1.4.0, I encountered a problem 
when trying to use the package System. I get a compiler error message 
that reads "intrinsic operator can only apply to numeric types" in 
reference to the following code in System:

   function "<"  (Left, Right : Address) return Boolean;
    function "<=" (Left, Right : Address) return Boolean;
    function ">"  (Left, Right : Address) return Boolean;
    function ">=" (Left, Right : Address) return Boolean;
    function "="  (Left, Right : Address) return Boolean;

    pragma Import (Intrinsic, "<");
    pragma Import (Intrinsic, "<=");
    pragma Import (Intrinsic, ">");
    pragma Import (Intrinsic, ">=");
    pragma Import (Intrinsic, "=");

Commenting out the pragmas get you past this, but then, of course, 
everything in the Gnat side that depended on System is officially out of 
date. This seems unacceptable as a fix.

Has anyone else encountered this? Is there a fix or workaround?

It would also be unacceptable because after commenting out these pragmas,
you would have to provide bodies for these operators.

I've used 3.14p and 3.3.1, and I have never seen this. It is also more than
a little surprising, for the GNAT version of system has had these
declarations for years.

I think this is a 'feature' of GNAT/GPS. I can't remember the
option off hand (I'll dig it out tomorrow at work - but I think it
had to do with "Mixed_Case"?)

Re: Gnat Error: intrinsic operator can only apply to numeric types

[Marin David Condic]

That could be it. I think I may have specified "Mixed Case" when 
starting the new project I was diddling with. I'll go turn that off & 
try again, but that really sounds like a bizarre sort of reason why a 
package wouldn't compile.

So much for the belief that Ada is going to eliminate bugs in large 
systems. :-)

Thanks for the help.

I have tried to use Mixes_Case for al while. Personally I am all in favour
of File_Name := Package_Name.

However in GNAT the special naming features are not fully tested (almost no
one uses them) and indeed bug ridden.

Use Mixes_Case and the compiler recompiles the base packages - which does
not work without "-gnata". Don't waste your time - even with  "-gnata"
System is a special case.

You could name every package with GPS - but eventually the system will run
out of internal storrage.

With Regards

Re: Gnat Error: intrinsic operator can only apply to numeric types

[Marin David Condic]

I guess I don't like it when programming environments (or any software) 
tries to "help" me. If I want to use mixed case filenames, I resent the 
program automagically "correcting" me and turning them into lower case. 
So I wanted to disable that. Unfortunately, I got bitch-slapped for my 
efforts. :-)

It still seems like a really high level of coupling to change something 
that relates to how filenames are handled and have it start causing 
compile errors on system packages. Your explanation starts shedding some 
light on it, but it still seems like a flawed design that should be 
rectified.

Rest asured, I've already given up on trying to customize the naming and 
formatting that GPS does. I guess I can have it in any color I want as 
long as its black. ;-)

No probs - check your .gps file for "for Casing use "MixedCase";" and
comment it out and try your build again. Please let us know if this
fixes it for you.

Does anyone know if ACT know about this one?

Re: Gnat Error: intrinsic operator can only apply to numeric types

[Marin David Condic]

Since it was a brandy-new project & relatively small, I just zapped the 
file and rebuilt the project allowing GPS to decide for me how I wanted 
things to appear. Prior experience with trying to change any of the 
pretty-printer options has proven that you either do it the GPS way or 
you use a different editor, so I guess I can get over the lower casing 
of my filenames. (That could cause problems if I had to share these 
files with a Unix system, but right now its just on two different PC 
platforms & two different compilers. But that would only start me 
whining about conditional compilation and other similar things again, so 
I'll stick to whining about what kind of SOBs would put out GPS with 
such obvious broken features in the project files... ;-)

I don't know if ACT knows about this one, but I've seen discussion here 
about broken pretty-printer capabilities and so I think they know they 
have (had?) problems with their project files on the PC side of things.

If you're running on Windows, GNAT doesn't seem to care what case file
names appear in anyway, so you can just go right ahead and mix the
case as you please. Since most of my serious development is Unix-based
I feel no desire to fight GNAT on this one, lower case is good (though
I have to say my GPR file names tend to mixed case, strange psychology
no doubt). It is Very Annoying to find that somebody has used mixed
case file names so that the project won't build on Unix ..

I have to say that GPS's editing environment seems very immature
compared to the latest (supported) emacs ada-mode. But we have
programmers who would rather fire up Notepad than drop their file into
GPS (does it do drag-and-drop?), let alone GLIDE!

Other bits of GPS aren't so bad (sorry, ACT, lots of folk on the team
do like GPS, I must be hidebound or something).

Re: Gnat Error: intrinsic operator can only apply to numeric types

My experience is that GPS will recognize the case-independent names on 
Windows just fine. But when you save something that had mixed case 
originally, it then zaps it to lower case - presumably "in order to 
serve you better..." :-) I find programs that want to change what *I* 
wanted into what they *think* I want to be extremely annoying.

That's probably because that's what you asked it to do though you may
not have realised it at the time! When you create a new project there is
a "name scene" options page and the default is 'lower case' (with options
for 'UPPERCASE' and 'MixedCase'). 100% of the time I have used
GPS I have never changed this option. In fact I doubt I've ever considered
using it.

I still don't understand what the problem is with it trying to recompile
system (its filename is in lower case anyway).

Re: Gnat Error: intrinsic operator can only apply to numeric types

[Marin David Condic]

No, I asked it to let me set my file names with any case I wanted. (Like 
turning off the stupid paperclip) When I did, the program ceased to work 
in even a moderately acceptable manner. (Like if turning off the stupid 
paperclip caused you to be unable to actually save any files you had 
edited.) So I didn't really ask it to do that. An "option" you can only 
set one way isn't really much of an "option" is it? ;-)

Its a very bizarre kind of bug though. You'd think that file name 
character case choices shouldn't have any connection to determining out 
of date-ness of compiler supplied libraries, much less force the program 
to try to compile them in some mode that it can't get through 
successfully. (If specific compiler options are required, would it be 
better for those options to be specified as some equivalent pragma 
inside the file?)

Ah, then you are using a version I've never seen before... but it has the
same bug...

Re: Gnat Error: intrinsic operator can only apply to numeric types

I thought that is what "Mixed Case" was all about. Am I misunderstanding?

I think maybe I am :-) I perhaps took your phrase "any casing I wanted" too
literally.

Perhaps the other thing to try, is to add "System" to the "exceptions" on
the file name convension page?

Move on. This was likely a feature that a specific customer asked for 
and it probably worked for them in a way that suited them.

Ask for version 2.0 if you want to get the latest.

Re: Gnat Error: intrinsic operator can only apply to numeric types

[Marin David Condic]

I wasn't. I was compiling something that with-ed System and GPS provided 
the subject line error message and presented me with the package System 
to edit if I so desired. Playing around with it hosed up the rest of 
things, so I just re-installed Gnat and things got back to normal - but 
the package System still shows up as having a bug in it.
