[M3devel] strange errors...

Sat Jun 23 20:36:32 CEST 2007

Mika:
I've used CM3 (v4.1) on Windows for years with Trestle, FormsVBT,
NetObjects, etc..
Make sure to use the v2 of Network Objects.
I haven't moved up to the most recent version yet.  I tried some time
ago, but ran into some problems with Bundles not working correctly. 
Maybe this is fixed now.  I should try again.
Regards,
Randy Coleburn

Hello everyone,

I am in the process of trying to consolidate build systems for a
few software packages I am maintaining.  Currently, I am using an
old PM3 on FreeBSD4, an ancient PM3 (from Klagenfurt?) for Windows
(NT386GNU), and trying to get the latest CM3 from cvs up and compiling
things on PPC_DARWIN.  Ideally, I'd like to standardize everything
on the new PM3---mainly so that I can use pickles (and Network
Objects) across all three systems.  I'd also like to add Linux to
the mix.

It's natural for me to start with CM3 on Darwin, as there's no
alternative.  But I am getting some assertions failing.  Everything
in the CM3 distribution compiles fine, and I believe I have compiled
the libraries a few times (that is, including with themselves), and
updated the compiler, too (using boot-cm3-with-m3.sh).  I just cvs
updated tonight.

Here's what I'm running into:

/Users/mika/t/parserlib/ktok/PPC_DARWIN/tok ../src/CHP.t -o CHPTok.i3 

***
*** runtime error:
***    <*ASSERT*> failed.
***    file "../src/runtime/common/RTCollector.m3", line 2314
***

Abort

Also:

/Users/mika/t/parserlib/ktok/PPC_DARWIN/tok ../src/PRS.t -o PRSTok.i3 
Illegal instruction

As you can see, these things are coming from the caltech_parser.  I am
using
our local version, but I don't think it is very different from what is
in the
CM3 tree.

Examining the first error (the failed assertion) more closely, I see
the following:

(gdb) list
108         wr := FileWr.Open(Pathname.ReplaceExt(tp.out, "m3"));
109       EXCEPT OSError.E =>
110         Debug.Error("Cannot open tok implementation output file: "
&
111           Pathname.ReplaceExt(tp.out, "m3"));
112       END;
113       Wr.PutText(wr, subs.apply(Bundle.Get(Form, "tokform.m3")));
114       Wr.Close(wr);
115     END Main.

Any ideas what to look at?

I don't know if this is relevant:

P.S. Am I correct in assuming that I can get CM3 to build on Windows?
I could switch to CM3 on Unix any time, of course, but I've never
had luck with it on Windows, which is why I am using the ancient
Klagenfurt PM3, which comes on 40-odd "floppies" and a .EXE that
unpacks them into C: (and installation instructions only in German).
If CM3 doesn't work on Windows, I am essentially wasting my time,
as the current project I am working on absolutely requires that the
software run on Windows 2003 Server (yes, it sucks, but what can
you do?)  The very old PM3 at least kind of hobbles along on this
platform---actually, better than that; it does Trestle natively
under Windows (no X required), at least on SOME Windows machines.

P.P.S. Sorry for all the postscripts, but is it true that the
build system has been changed so that building with overrides (cm3 -x)
requires having the compiler sources available?  It didn't use to
be that way, but I can't get Network Objects to work with overrides
now unless I have the sources available...  It's a bit of a pain
because it means that every user has to have the compiler sources,
or else ship everything, or was that not the intention?
