[PATCH/libgui] Fix cygwin build woes

[Keith Seitz]

Hi,

I've committed the attached patch which should fix any problems with
building libgui on cygwin. At least, it builds on *my* cygwin box.

NOTE: Not tested (and probably won't work) with mingw!

Please let me know (via this list) if there are any problems.

Keith

So where does cygwin stand now, Keith?  Is it time to decouple insight
from the gdb release, make it a standalone release, and make it rely on
X?  Is there a version of tk out there which works with on native
windows?

I don't really know where cygwin stands. Right now, the versions of Tcl,
Tk, Itcl, and Itk that are in sourceware are really hybrid monsters.
There is no active cygwin maintainer for Tcl. That means native binaries
only (which can be downloaded from ActiveState). Or someone could build
his own binaries, based on the work that's been done on sourceware.

Itcl and Itk were pretty trivial to do, but I'm sure Tcl and Tk would be
a bit tougher. But I don't see why it could not be done.

I have no opinion on moving Insight to X on cygwin. Insight's only
requirement is Tcl and Tk, and it doesn't care how it gets it. :-)

I'm only attempting to decouple insight from Tcl and friends. I've tried
ripping insight out of gdb, but it is a major, major pain: GDB abandoned
libgdb way too early to make this possible. So insight will stay where
it is.

My play, actually, is to abandon insight altogether, but I don't know
when. In light of that, this has been an effort to get rid of some of
insight's worst baggage. Licensing issues have made it possible so that
only a Red Hat employee can easily work on insight (or at least anything
non-trivial). So insight sits stagnant. I think it is simply time to
move on.

I am faced with three possible decisions:

1) Keep up with insight, fixing bugs, rewriting what I can here and
there, i.e., maintain the status quo.

2) Redesign/rewrite insight (probably move away from Tcl, too)

3) Abandon insight and devote time and energy to another project.

I know what I would like to do, but it's a huge undertaking, and I am
not entirely sure I am either up to the challenge or have the time to
wait for sufficient community momentum. Or worse, I commit a boatload of
time and there is never any momentum -- just this situation insight
faces today.

Yep.  Understood.  I'm sort of tired of fielding questions about them
actually.

I asked in the cygwin list and most people claim to be reluctantly ok
with an X requirement.  I was counselled not to make raw gdb rely on X
however (well duh).

Apparently a lot of people are using it.  I was surprised to hear that.

Since Red Hat was willing to release insight to the FSF would they also be
willing to just relinquish ownership entirely?  Would that make working on
it easier?

Cygwin needs an X maintainer.  :-)

I think if you committed the time people would notice and might even
pitch in.  Aren't there some companies still using insight?

Were you thinking about possibly using gdb/mi?

  Once I've got gcc4 and setup.exe under control, I'll volunteer some time
and attention toward helping with insight.

  I really quite like the look-and-feel of the current insight, and the
independence from X, and I'd be willing to take a look at the tk/tcl/etc
"hybrid monsters" with a view to modernising them (refresh relative to
upstream sources) and making them build and run good for both cygwin and
mingw on windows, if that turns out to be possible.

  Nooooooooooooo!  Don't thank me now or there goes all my incentive!  Wait
until I've got it underway at least!

Ok! Then I'll resort to begging:
Please, please, puh-leeaassee, if you could spare one teeny, tiny moment of your spare time?... :-D

  Nooooooooo!  That'll just bring reverse psychology into play and I'll feel
like I'm being nagged and start to get all resentful and defensive and not
want to do it!

  Probably your best strategy is to say nothing about it at all until I've
completely forgotten about the whole thing, then jump out from behind a bush
screaming incoherently while belabouring me about the head with a hippo.

  Although I can't be 100% sure that will work, I feel it has the best
chance of success!  :-D

I see that you've volunteered to help out with insight.  Can you tell me
when the next release will be?  I have some unspecified vague bugs that
may or may not be my fault and I was hoping that you will have
automatically fixed them when you make your new release.

Incidentally, I'd suggest rewriting insight in Ada.  I think you'll
definitely have fewer problems going forward that way.

HTH,
