Ada on PDA - success!

Ada on PDA - success!

[Wojtek Narczynski]

Hello,

I managed to build GNAT cross compiler for Sharp Zaurus PDA -
http://www.zaurus.com. It was relatively easy, as Zaurus runs Linux.

GCC 3.3 did not work for arm, because there is something undefined for
arm architecture regarding exceptions and libgnat did'n want to link.

The GNAT version from libre.act-europe.fr worked. I had to fix a few
glibc header parameter names, but it was pretty easy.

For complete happiness I'd need to interface GNAT5/GCC 3.2.3 code to
C++ compiled with 2.95.x (Qtopia on Zaurus is compiled with it). Does
anybody know wether it's possible, and how to do this?

Regards,
Wojtek Narczynski


P.S. Here is a'screenshot', it's not a fake :-)

# uname -mr 
2.4.18-rmk7-pxa3-embedix armv5l

# ./hello 
Hello cruel world.

There are two Zaurus PDAs. The SL5600, which uses the IntelR 400MHz XScaleT
processor and the SL5500, which uses the StrongARM SA-1110, 206MHz. Which
does your version of GNAT work with? Can you cross-compile from a PC running
Windows XP?

No offence, but that's the easy part. Try porting the runtime. Cross
compiling for another Linux platform is easy.

Luke.

No problem!

When you do it second time ;-) Seriously, in this case getting to know
which sources to use was the most time consuming part. Maybe posting
this information here will save somebody this time in the future.

There is no need to port runtime for Zaurus, because it is supposed to
run Linux. Yeah, currently it aborts with 'Tasking not supported', but
I think it's the problem of bad choice of files for libgnat.  I'll try
to fix the Makefile later this week.

I don't think I'm going to try to port the runtime any soon though...

With SL5600, but it should work on the slower one as well. Do you have
the hardware to give it a try?

Dunno, haven't tried. If you can build native, cross should not be any
harder.

So I did, then diners example is now working over pthread tasking on
Sharp Zaurus PDA.

Are the ACVC tests freely avaliable? I cannot find them anywhere. And
if not, are there some other tests I could run?

The ACVC test suite is now called ACATS.  It is available at
www.ada-auth.org.

ACVC has been superseted by ACATS.

See the web page:
http://www.adaic.com/compilers/testing.html

Here's a link to the tests themselves:

SAL (http://www.toadmail.com/~ada_wizard/) comes with a complete set
of tests. They have found bugs in most of the pre-releases of GNAT,
including the latest; if you are using GNAT from gcc 3.3, you'll find
the same bugs :).

I used GCC 3.2.3 and GNAT 5.01w (from libre CVS). It worked:

# ./test_all_harness 
   Total Tests Run:  22

   Successful Tests: 22

   Failed Tests: 0

   Unexpected Errors: 0

Thanks & regards,

That's good. However, not all of the SAL tests are in
test_all_harness; that's an AUnit test harness, and only the most
recent tests are in it. Run SAL/Build/Gnat_Debug/Makefile for the
complete list of tests; most generate an output file which is then
diff'ed against a known good output file.

GNAT 5.01w from CVS should in fact have all the bug fixes.

My cross compiler passed 2302 (+ 12 tentatively) of 2371 I managed to
compile for it. I have no idea what it means though :-)
