[Ada] Partial bootstrap success on Debian/x86

[Ada] Partial bootstrap success on Debian/x86

[Florian Weimer]

I'm glad to report that current CVS is close to building
out-of-the-box on Debian (x86 architecture, not-too-current sid),
using the Debian gnat package (which includes a driver called
"gnatgcc") and the C compiler of GCC 2.95.4 20010721 (Debian
prerelease).  The stage3 binaries seems to be able to compile
correctly most of my code, at least my test cases work. ;-)

Only the xnmake problem reported earlier and the debug information
comparison failures remain.

Lutz Donnerhacke mentioned another problem which didn't occur to me
because it also exists in the public GNAT releases (and I've got a
proper build environment for them):

The makefile tries to link with libaddr2line.a.  This library does not
exist on most systems, and it is not part of binutils (there's only a
addr2line command, which seems to do roughly the same).

I've never seen source code for this library, so I can't tell if it's
feasible to build it during the GCC build.

I'm on the way to provide a addr2line.c for the gcc tree. Should not take
longer than some weeks.

After reading most of the various threads relating to ada being added to
cvs head, I've tried various ways to bootstrap, nothing succeeds as of
now.

I use Debian unstable(updated daily) and use CC=gnatgcc in my build
scripts. I used gnatmake to make xtreeprs xsinfo xnmake xeinfo and place
them in /usr/local/bin. I try to bootstrap daily and have seen various
different errors every day.

Today's error:
gnatgcc -c  -DIN_GCC    -g -O2 -march=i686 -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic

Any pointers on your method of success?

Neither should be necessary with current CVS.  

Could you give the instructions in < 873d4pdist.fsf@deneb.enyo.de > a
try?  Especially on Debian, you shouldn't need to see any environment
variables or compile any helper applications.
