compiler errors in GNAT 304a (win95)

compiler errors in GNAT 304a (win95)

[James Conley]

I was writing a simple program that used text.io and overrode put() to
put an array of integers.  I have yet to have it work right, but I got
a strange sieris of errors from gnatmake - it tells me that system.ads
and ada.ads has been modified and that I have to recompile everything
that depends on them (text.io,etc about 30+ sources..).  I haven't
modified anything that I know of except my little program that is in a
seperate directory alltogether!  This seems awful strange, is this
common? mabye I accidently changed the date on one of these files
while moving them to a different directory or something. - how would I
recompile all these files?? Do i just go to that directory and issue a
gnatmake for each file it complains about? please let me know if
anyone has any idea why it would do this and how to fix it please.
Thanks!

Funny you should have that problem, I had the same on all of my adainclude 
files this morning when I tried to compile my lab. Don't know why it happened 
but I just deleted gnat304a and reinstalled it, it works fine now.

Hey - this is a good point; nobody has ever raised this issue with us.
The conversion was added to help people move code from Un*x to DOS.
I do _not_ think the file is automatically updated (i.e. stored).
It certainly shouldn;t be, until you close the window, in which case
AdaCAPS should ask for confirmation before rewriting the file.

If AdaCAPS is _really_ modifying a file and changing a timestamp
without your permission, that's a bug that needs to be corrected.
Please try this and let me know. I will try it too when I have
my PC handy.

It is true that changing the timestamp on an interface file from
the runtime is a bad idea. OTOH, I'm not aware of any bodies that
are not provided. It's best not to touch (in any sense of the word.:-))
anything in the runtime.

I had a similar problem with the DOS version and Adacaps.  If
you try to bring any of the *ads files into Adacaps to just see
what facilities the library packages offer, Adacaps will ask you
if you want to change the file format from LF for ene-of-line to
CR-LF.   If you say yes, it automatically updates them for you,
and you are out of business.  This changes the date-time stamp on
the file, which means it has to be recompiled, but the *.adb source
files aren't all available, so you must re-install GNAT to
recover.

I had the same thing happen.  I re-installed GNAT and it seemed to work
ok.

Thanks for everyone's reply, seems like I'm not the only one.
I had to reinstall GNAT, but then it happened again and the second
time I went to ~adaincludes subdirectory and ran gnatmake -a on the
files that it said had been 'touched' (only have to do this on a few
files since so many of them depend on others) and moved all the .obj
and .ali files to the ~lib subdir replacing the non-touched versions.
and everything seems to still be working.  I have had to do this twice
now.
