ADA.CALENDAR.TIME_OF problem with cygwin gcc-ada

ADA.CALENDAR.TIME_OF problem with cygwin gcc-ada

[Roger Blum]

Hi everybody,

I 'd like to use the function TIME_OF in the package ADA.CALENDAR to convert
a date/time (string format from database "DD.MM.YYYY HH:MI:SS") to a TIME
type in order to calculate intervals between dates etc.
Although I call the TIME_OF function with correct input, it raises a
CONSTRAINT ERROR (I'm using gcc-ada from cygwin).

Anybody any idea what the problem is and how I can solve it?

Thanks.

Roger

The problem is that the Ada compiler that comes with Cygwin is seriously
flawed. The solution is to download and use the latest GNAT public release
(version 3.15p). I could not re-create the problem with this compiler.

It is a shame that the first Ada compiler distributed with Cygwin was not
better.

Hi Frank,

Thanks for your reply.

I 've used GNAT 3.15p before. I was urged to change to cygwin Ada because I
have to link my project with some c++ libraries, which isn't supported by
GNAT 3.15p (means I haven't found a way to do it).

I suppose I have to write my own calendar package to do the date
calculations.

What time_of function is this? I can't see any that takes a string
as a parameter...

The only one I know of is this one:

   function Time_Of
     (Year    : Year_Number;
      Month   : Month_Number;
      Day     : Day_Number;
      Seconds : Day_Duration := 0.0)
      return    Time;

It's of course the function mentioned by you. Before calling it I split and
convert the string accordingly.

This is one that I reported! 9536 on 2003-02-01 against 3.4
experimental, but present in 3.3. Fixed 2003-10-21.

Mingw has a GCC 3.4.0 candidate release with an Ada compiler and with
a C++ compiler. Maybe this works better than the cygwin versions.

Thanks for this hint. I'll try this one.
