Martin, what is the right way to completely[1] disable motif by
default on irix ? The copy/paste motif-related bug[2] is heavily
depending of the patching level of the system and I'm not able to find
out which patches are necessary. These are not XEmacs bugs per se, so
I don't think this iss fixable.
Of course it should still be possible to force motif in if one wants
to.
While we're at it, what would you think about warning messages for
some particular combinations of flags on some platforms at the end of
the configure ? Like for:
- linking motif in on irix
- not using union type on alpha[3]
- everything from PROBLEMS I'm not thinking about
OG.
[1] The equivalent --with-dialogs=athena and --with-xim=xlib
[2] segfault within a motif function/bad data abort()
[3] Inflooping in the garbage collector for some combinations of
compiler/system. I am able to reproduce it, but have lacked time to
track the real problem.

The things that COULD be motif are
--with-menubars
--with-scrollbars
--with-dialogs
--with-xim
Of those, the only ones that DEFAULT to being motif (where available)
are --with-xim and --with-dialogs.
So `--with-dialogs=athena --with-xim=no' is one combination that
should disable use of Motif. Let me know if this is not the case.
I understand many would like to never use motif. We may add an option
like that later, but don't we already have too many configure options?

There is lots of work of this kind we could do in configure in 21.1.
When we add these extra checks, it would be nice not to slow down
configure any more.

It is. I was afraid of tooltalk in particular. I'll try to include it
in a non-motif configure to see.
But I think you missed my point. I'd like to see motif NOT being
default on irix, even if available. While still having the possibility
to ask for it explicitely (i.e. no forced removal in s/* files).
Is that possible ?

That may or may not being interesting, but isn't what I'm looking for.
I'd just like to avoid by default a library that is often (but not always,
and no way that I know of to check at compile time) buggy.

My previous list was incomplete. CDE is built on top of Motif, so
--with-cde naturally requires motif.
Tooltalk is packaged as part of CDE, so the natural comination is CDE
+ tooltalk + Motif. It is interesting to try to build --with-tooltalk, but
without Motif. This might work, since libtt.so has no direct
dependency on libXm.so.

We currently have a check for lesstif. Should we also have a check
for Irix, and avoid using Motif there?
It's getting late in the 21.0 cycle, but.... Olivier, if you think
Motif should be disabled on Irix for 21.0, then you should make it so.
You will have to take responsibility for the patch to configure.in.

Yes, but only by default. If the user asks for it, he can force it in.

I, Olivier Galibert, XEmacs beta-tester on Irix 6.2, 6.4 and 6.5SE,
hereby take the responsability for any patch which target is to change
the default feature selection when configuring on Irix in order to
avoid Motif.

Now, I know that doing that will reduce the number of crashes. I'm
probably able to do the patch, but asked you because you know better
than me how to do it properly in order that it fits well in your
rewrite of the configure.in. Your choice ?

Currently, configure is not really set up for this sort of thing.
Motif is chosen by the features that need it.
We could default things as follows:
When we're deciding what kinds of dialogs to use, and the user hasn't
specified, then prefer athena to motif on irix.
When deciding whether to use CDE and Tooltalk, and the user hasn't
specified, then say NO on irix.
When deciding whether to use XIM/Motif, and the user hasn't
specified, then say xlib on irix. We already have a model
for changing the behavior of the --with-xim flag if lesstif is
detected.
This does not exactly make for clearer code.
Because of the evil effects on the maintainability of configure, I
recommend the idea just documenting it in PROBLEMS, or trying harder
to find a workaround.
Olivier, you're still welcome to try to make a patch using the hints provided.

Here we are. I really think this will avoid a bunch of bug reports[1]
since lots of people do not read PROBLEMS.
I tried to do that in a clean way. What do you think about it ?
OG.
[1] And crashes, incidentally :-)
