Are you remembering that "gnatbl" in 1.83 does not create a .EXE file, but
rather a COFF executable.  If you create your executable with:

     gnatbl test1 -o test1

Then you can execute it with:

     go32 test1

or convert it to a DOS executable with:

     coff2exe test1

I've heard that "gnatbl" in GNAT 2.00 generates DOS executables directly.

By the way, send all problems with GNAT to gnat-report@cs.nyu.edu.  Your

This has not been explained very well in NYU's documentation; I think
they are changing the docs. It is inherent in the djgpp system that
GNAT rides on top of. Read the djgpp.faq file that is (I think)
included in the djgpp zipfile.

which produces test1.exe.

True. Doug Rupp has very considerately included the coff2exe step in
this version of gnatbl. A round of applause for Doug!

It does.  I just downloaded it from nyu and installed it over my 1.83 
installation and then compiled the hello world example with no problem.  
It does build an .exe file right out of gnatbl.  One caution, make sure 
that when you run gnatbl that you use the -o option and name your file 
xxx.exe (DOS expects either a .exe or .com or .bat file when typed at the 
command line).

I have used version 1.83 in DOS since it has become available and
I now have at least a dozen students attacking v. 1.83 in a DOS
environment with great success.  I have a copy of the CDROM but
I have not used that copy.

TRUE:  I've been using 2.00 in DOS for about a week and, yes, it
creates DOS executable files (I found out the hard way, I have this
terrible habit of not reading readme files).

  From my experience, it seems that the coff2exe program does not
  generate a real MS-DOS executable.  It still needs to find
  the go32.exe program in order to run the file.  I found this out
  when I tried typing "hello" and my PATH did not have the directory
  containing go32, thereby causing it to complain about not finding
  go32.  So my question is the following: What does coff2exe do for
  you besides save you a little typing?  Am I missing something here?
  You couldn't take your "exe" file to another machine and run it.
  You would have to bring along some additional baggage.


  Thanks,
  Pete R.
Hello there

Re: GNAT problem: Hello World

[Pascal OBRY]

Well actualy you can create a real .exe program with go32 in it.

	coff2exe -s go32.exe <prog name>

This will create a program sufficient by itself.

Pascal.

GNAT problem: Hello World

[Jacob Sparre Andersen]

I've got a problem with GNAT-1.83-DOS (just downloaded from ftp.cdrom.com 
yesterday):

The Hello.adb example freezes the computer when I try 
to run it. It seems to compile and link fine.

Could somebody please help me (or point me to some help).

Regards,

I'm having exactly the same problem too !

I've even tried typing a short program myself, but this tells me that the
program is too big for memory.  This is impossible as it is only a few
lines long.  Anybody ?

some time ago I posted the remedy but this obviously did not arrive.
So, once again the remedy:

Maybe some of the problems can be removed for some
by looking at my compile-link-go - file I produced
yesterday evening after getting angry about myself
having forgotten to apply the @#*% "coff2exe" step:

begin of contents of command file clg.bat on MSDOS6.2 :
gcc -c %1.adb
gnatbl -o %1 %1.ali
coff2exe %1
%1
end   of contents of command file clg.bat on MSDOS6.2 

I am using this multistep with one parameter
(where tst is the unit name AND the filename(part) ):

   clg tst

When I have other packages to "with"
I compile them (first) separately with e.g.:
   gcc -c tstpak.ads
and
   gcc -c tstpak.adb
and then finally compile, link, go with
   clg tst

The good news: it works :-)
The bad news: It's nowhere documented (at least
              not inlined the cookbook recipes ;-)

Re: GNAT problem: Hello World

[Robert Dewar]

alwys send messages to gnat-report for help on GNAT. Proibably the error
her is the failure to run cofftoexe (see DJPP documentation). The requirement
for doing this is eliminated in versiuon 2.00 (where GNATBL does this
automatically).
