RedHat 9 / GCC 3.2.2 - Florist 3.15p compile error

RedHat 9 / GCC 3.2.2 - Florist 3.15p compile error

[Kurt]

I looked for an FAQ, but no luck.

When I build Florist 3.14p or 3.15p with gcc 3.2.2, I get a range error:

gcc -c -O2 -gnatpg deps.adb
posix-signals.ads:121:33: warning: static value out of range of type 
"Signal" defined at line 57
posix-signals.ads:121:33: warning: "CONSTRAINT_ERROR" will be raised at 
run time
gnatmake: "deps.adb" compilation error
make: *** [deps] Error 4

I'm a little rusty at Ada, but looking at the code:

 From 'posix-c.ads':

    SIGRTMAX : constant := 64;
    SIGRTMIN : constant := 34;
    NSIGS : constant := 63;

 From 'posix-signals.ads':

    type Signal is
      new System.Interrupt_Management.Interrupt_ID'Base
      range 0 .. POSIX.C.NSIGS;
    for Signal'Size use POSIX.C.int'Size;
  subtype Realtime_Signal is Signal range
      POSIX.C.SIGRTMIN .. POSIX.C.SIGRTMAX;

I changed:

  subtype Realtime_Signal is Signal range
      POSIX.C.SIGRTMIN .. POSIX.C.SIGRTMAX;

to:

  subtype Realtime_Signal is Signal range
      POSIX.C.SIGRTMIN .. POSIX.C.NSIGS;

And, it compiled.  Any ideas on this?

GNAT in GCC 3.2.2 is a very old prealpha of GNAT 5.0. I suggest you either install GNAT 3.15p
(which is stable) or GNAT 5.02 from ACT's CVS (which is not yet stable, but much more stable
than GCC 3.X).
