Do you mean more back-compat fixes are necessary beyond that in the 
2009-09-20 snapshot?

  With this particular problem, everything built back before the first release
of the DLL that had malloc wrappers implemented will provoke problems now that
there's a new libstdc++ that works in concert with the wrapper system.

  Everything before the 0924 snapshot is vulnerable to this problem when using
the newer libstdc++ and running an older exe, or to be even more specific,
everything before r1.362 of dcrt0.cc.

  Fortunately we can fix this in the cygwin DLL (and the fix I'm going to put
in there will be more comprehensive anyway), so there isn't any need to
rebuild your whole world, but it'll take a little time to test the patch and
get a new release sorted out, so if there's anything you *especially* want to
use in the next 24-36hrs, you have fallback options of :

- rebuild it
- rollback your libstdc++ dll
- rollforward your cygwin1 dll (i.e. install the snapshot)

[1.7] Uploads: 2009-Oct-05

IMPORTANT:
cygwin-1.7.0-62 contains an important fix for all the fork() and 
dlopen() errors which have been plaguing Ports for months.  Please 
update to this version before reporting any bugs.

Highlights:

* GIMP 2.6.7 (built-in help browser re-enabled)
* KDE Education suite
* PHP 5.2.11 (added: php-mbstring)
* VLC 1.0.2

Please note that once again a number of packages have been moved from 
Ports into the distro, so be sure to update from there as well.

The list of new and uploaded packages is attached; for the complete list 
of packages currently available for 1.7, please check the FTP server: 
ftp://sourceware.org/pub/cygwinports/portslist-2.txt

Please also consider using a mirror (but make sure it's current first): 
    http://sourceware.org/mirrors.html

Enjoy!

Downloading Problems.

Hi.

I followed the instructions for dowlonading (all) packages once, a
number of months ago.  Everything worked fine.  Subsequently, I have
tried again, a number of times and separated by a number of months. 
Each time, I get through all of the windows until near the end, it looks
like it's about to download something, but then it gives me the final
window, saying "Installation Complete", without downloading a thing. 
the first time, I thought that maybe nothing in the packages had
changed, but this time I've been reading the list, and it's clear that
things have changed.

So, I'm not clear what is going on here.  The only thing that I see
happening that is not mentioned in the download instructions, is that
when the setup.ini is downloaded form the mirror, a window comes up
telling me that it is older than my present setup.ini,and it asks if I
want to continue.  I just answer "yes".

Is there anything that I'm missing?

Thanks -
DA.

Downloading Problems, part II.

I went back and tried yet again:

(1) Setup's "Partial" view under "Select Packages" shows that there is a
long list of things that are supposedly about to be downloaded, but I
click "Next' and ...

(2) the window becomes:

> Cygwin Setup

Progress
	This page displays the progress of the download or installation.

----------------------------------

	Parsing ini file "ftp://sourceware.org/pub/cygwinports/setup.bz ...
	setup.bz2 from ftp://sourceware.org/pub/cygwinports
	405504 28.0 kb/s
	Package: 
	Total:
	Disk:

(3) It sits there for a moment, and then without downloading a thing,
flips over to a new window:

> Cygwin Setup

Installation Complete
	Shows installation status in download-only mode.

Re: Downloading Problems, part II.

Make sure on the final run of the setup.exe, you have "Install from
local dir" checked.
Make sure you've run the sed cmd on the previous step as well.

Using the "Prev" view is always a good idea too.

  That sed command is going to need updating at some point, because newer
versions of setup.exe are going to stop using the /etc/setup/last-cache file
and start storing all the settings in a single /etc/setup/setup.rc:

  I think this behaviour must have gone live in the latest update of
setup-1.7.exe on cygwin.com.  Right now that would probably only make a
difference if you've changed your local package directory, or if it's a fresh
install that's never had an /etc/setup/last-cache file, but sooner or later
the instructions on the website will need changing.  FYI.

    cheers,

Re: Downloading Problems, part II - Thanks Will, but Downloading is the Problem, not Installing.

Will - thanks for the input, except - all I'm trying to do at this point
is get setup.exe to _download_ the new stuff.  After that, I'll run the
sed cmd and "install from local dir".  The problem I'm having is
downloading.

DA.

Re: Downloading Problems, part II. Dave - Thanks, but I'm not using 1.7, nor is it a new install.

Dave - you are probably making a useful point.  With regard to the issue
I'm having, though, I'm not using 1.7.  And, this was not a fresh
install; nor, have I changed my package dir.  I did the install a number
of months ago, and am trying to update it now.  There is a lot of new
stuff listed in setup, but when I try to download it, it makes as if to
do it, and then downloads nothing at all.

DA.

Maybe nothing. I might be that the packages are indeed already downloaded. To my
knowledge setup only checks for what is installed. And this might be another
version from another server so setup will offer to download the cygwinport
versions. Did you check the download directories? I'd suggest doing the sed
trick and seeing if "Install from local directory" will offer to upgrade some
packages.
