Emacs 22 (CVS) and ada-find-**-references

Emacs 22 (CVS) and ada-find-**-references

[Jérôme]

Hello

We are evaluating current CVS build of Emacs 22 (on Windows)

One of  our last problems deals with Ada programming mode :
When we use the function ada-find-**-references, the file-name is not
correctly identified
(And so, when using next-error function,it does not jump to the
corresponding line.)

Any idea where I should start to look ?
(I am not very familiar with compilation-mode.)


Here is what I saw in my after buffer

-*- mode: compilation; default-directory:
"c:/CVS-CO/HEAD/hera/interf/src/oci/" -*-
Compilation started at Tue May 30 16:00:38

gnat find -rf oci_test:oci_test.adb:17:11 oci_test.adb
-pc:/Work/HEAD/debug/g-oci_test.adp
.\oci_test.adb:17:11: (spec) Oci_Test
...

Compilation finished at Tue May 30 16:00:38

NB 1 : Of course, this is working fine in Emacs 21 (with same gcc
release, same .adp file)
NB 2 : When I compile, in case of warning/error, there is no .\ before
the file name

Hello

I found a workaround : I added a change-directory to build_dir before
to start gnat find. I will try to go deeper inside compilation-mode
later.
See diff file below.

As there were quite few answers, it would be interesting to know what
IDE is the one you prefer to work with gnat/gcc on Windows (GPS ?,
Emacs/ada-mode ?, ...)

Please feel free to give your opinion.

Since ada-xref.el defines ada-cd-command and ada-command-separator,
that's a reasonable fix.  But the usual way to affect compilation-start
and friends is to let-bind default-directory.

Why restrict the survey to Windows? I use Emacs/ada-mode as my preferred 
IDE in both Linux and Solaris. I hope Emacs 22 will come with an 
improved support for Ada. Sorry that my knowledge of Emacs Lisp is not 
enough to help.
