No lobbying required.  Nabble has a wiki-like system so anyone can change

When is next official cygwin net release?

Is there going to be an official cygwin net release soon?  The  
current one is 6 months old, and I could really use an official fix  
for <http://www.cygwin.com/ml/cygwin/2006-02/msg00334.html> in order  
to deploy a Cygwin install I am testing.

Also, it would be good if the above bug were listed in <http:// 
cygwin.com/faq/faq.known-problems.html>, and there was a FAQ on the  
Cygwin site with the current estimated release date of the next  
official release.

Thanks,

John

I chimed in earlier in this thread because I didn't want you to start
working on an implementation which I'd have to reject at some later point.

I just want to be clear here.  I really do want to be convinced that the
current implementation in cygwin can't be fixed before we scrap that and
implement something new.  The person who submitted the original change
thought that it should be possible to fix the problem but he never
followed through with a fix.

Customizing setup.exe (How to specify "default" packages)

I know this has been asked before but I have not yet found a real answer.

  ---> How does setup.exe "decide" which packages are to be installed by
default?  <---

I do not see anything in setup.ini that controls this.  It is also not
hard-coded in the setup program itself, as far as I can tell, nor does
there seem to be any other obvious external source (file) which provides
the necessary information.

I have seen the suggestion that any packages placed in "Base" will be
included in the default package list, but that seems like a bit of a kluge.

I have spent hours with google, and hours studying the setup.exe source
code without any success.

Does anyone have a answer to this?  Is it just so simple that "any six
year old" could see it, but I'm no longer six?

Thank you,
Harry Dellicker

But those of us who do not use nabble but do try to maintain up-to-date
instructions on the web sites that we manage are not particularly
interested in getting sucked into maintaining descriptions at two
separate sites.

There is a catch-22 here, I guess.  If Nabble really catches on, it
might be necessary to start blocking them just to cut down on people
sending email without understanding the rules.

Maybe you guys ought to read the existing source code before discussing
this.  There are already dozens of calls to InterlockedIncrement,
InterlockedDecrement, InterlockedExchange, and
InterlockedCompareExchange in the codebase, and if you look at winbase.h
you'll see that these have been #defined to be inline assembly versions
of the functions.

That is it.  Setup.exe will automatically select "Curr" for any package
in "Base" (and any of its dependant packages) that is not currently
installed.  I wouldn't say "the default package list" because there is
no list and because it's not just a default, i.e. if you uninstall
something in category "Base" then setup will try to install it again the
next time around.  It's more like "anything in this category is taken as
required and always will be selected for installation if not already
installed."

Simple.  Everything in the "Base" and "Misc" categories is installed by
default.  Any package that an installed package requires is installed by
default.  Shampoo, rinse, repeat.

> I do not see anything in setup.ini that controls this.

You didn't look hard enough.  It's everything with "category:.* Base" or
"category:.* Misc".

Ah, but it *is* hard-coded in setup.  In two places.  See
PickView::defaultTrust() and packagemeta::set_action().

Perhaps, but that's how it is.

Re:MEX interface + DAE solvers in Fortran + gnumex/cygwin/mingw

I receive the mailing list in digest form, so forgive the lack of threading on
this reply.  BTW, good to hear from a Rose-Hulman student (I am an alum).

I think your basic problem is that you don't need cygwin _and_ mingw installed.
 You need one or the other, but not both.  Since the web site you refer to
mentions that cygwin gcc doesn't always work with matlab, I would suggest you
forget cygwin and go with mingw (and msys) all the way.  Try that, and if it
doesn't work, at least your problem is simplified, and it may be easier to find
an answer.  And BTW, you can't post mingw issues here - this list is cygwin
only.

Wnen you have a minute, take a look at the cygwin octave package - it can do
most of what matlab does, and there is even some mex compatibility if you
install octave-forge.
