gnatmake problem

gnatmake problem

[Dmitry A. Kazakov]

Did anybody experienced weird problems with linux gnatmake (gcc-gnat
version 4.4.3-4). The problem manifests itself when dealing with a cifs
volume (mounted share). gnatmake sees no files there. When I type

$ gnatmake x.adb

I get:

gnatmake: "x.adb" not found

$ gcc -c x.adb

works. The gnatmake from GNAT GPL 2009 sees files as well.

But you have gcc/gnat 4.3.x, that worked to me too. GNAT GPL 2009 is 4.3.x.

The bug seem to be introduced with gcc 4.4.x. I discovered it when I
upgraded Fedora to core 12.

Have you tried gnat-gcc-4.5.x? It does not take very long to build it.
I even built for Windows using MinGW.

I haven't. gcc-4.5 will appear first in Fedora 13.

Fedora team does this. Alas each time the gcc goes up to the next version,
something breaks in gnat. I doubt it were simple to fix by mere
recompilation. (I even tempted to install Debian on a VirtualBox and try
out gnat maintained by Ludovic...)

> I even built for Windows using MinGW.

GNAT GPL 2009 still works under Windows, but it ceased to do under Linux
when gcc-4.4.x arrived. There was something bad with many libraries, I had
no time to investigate.

You remind me that I moved from Red Hat 8 to Debian 3.0 "Woody" back
in 2001 precisely because I got frustrated at bugs and their dropping
support for Ada between 7.3 and 8. At the time, Samuel Tardieu was the
maintainer and I still thank him for his excellent work.

Since you do not provide any sources, I cannot even try to reproduce
your problem on Debian. I also do not see any bug report in upstream's
bugzilla database. Maybe you reported the problem to Fedora?

The worst thing of Fedora is these idiotic major core versions, which
cannot be upgraded to. You can upgrade the kernel, but cannot the
distribution. It is pathetic. I tried it each time and each time was forced
to reinstall it completely. Are all Linux distributions like that?

No. This is why I asked if somebody had similar problems. GNAT Pro 6.3.1
does not have these problems. (Normally I report to AdaCore. Most of the
problems were/are related to generics and, recently, to the interfaces.)

Luckily, no!

Debian's philosophy is "install once, upgrade many" and indeed, I only
install once per machine. I've had my current laptop since November
2006, when I installed Debian on it, and it have upgraded it
constantly ever since. I normally upgrade every week or so, tracking
the "testing" distribution. I have also successfully upgraded servers
from one stable release to the next several times.

Sounds promising. Upgrading to Fedora Core 13 dismays me. And Debian seems
to be the best maintained Ada Linux distribution.

That's good to hear. I am a Debian fan as well. I even have
it running on an old Dec Alpha machine, which I should boot
up again and update. ;-)

Unfortunately, you are out of luck; there is a regression in GCC 4.4 on
alpha which caused us to drop support for that architecture from all Ada
packages in Squeeze.  You'll have to stay with Debian 5.0 "Lenny", or
perhaps upgrade to it.

What is x86?  i386 and amd64 are quite different, so the generic "x86"
is not helpful.

You can report the problem to the Debian bug tracking system;
instructions at http://bugs.debian.org.  You can attach source files in
your email but it would help if you could isolate the trigger for the
bug in a small test case (as opposed to thousands of lines for the
complete closure of the file you were trying to compile).

If you look at eg http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42978
you'll see about 12 lines after the heading a table with a greyed header
row 'Attachment' and, in that case, the second row contains a link
'Create a New Attachment'.

i386, however when GNAT crashes compiling *.abs files it does that
independently on the platform.

Unfortunately it cannot be sufficiently reduced. I removed everything from
the package body, but it is still a lot of *.ads files. Presumably the
problem is with generics (the most frequent reason), but I cannot tell.

No, I think you have to create the PR first, then add the upload to it.

I wouldn't want anyone to think I'm a Bugzilla fan; in particular, the
search facilities rarely find anything for me.
