I like this idea.  Because history shows we cannot count on having
independant releases of libffi from upstream, I having a separate
package of libffi (or libffi-derived/rebranded/whatever) library makes
sense.

I am perfectly fine with the idea of starting making idependant releases
of libffi within Cygwin.  This sounds little crazy that somebody who
just wants to compile SableVM has to fetch whole gcc-java package (which
is not small and actually does not contain everything we need).  This is
IMNSHO very good reason to have such releases within Cygwin.

Besides having this library available in Cygwin, we would also make _the
same sources_ available for people for independent download.  This way
we would not need to point people "Go, fetch huge GCC sources, maybe
hack a bit the build system, and compile yourself libffi".  This
involves no additional work over what's required to maintain Cygwin
package.

Now I am seriously risking confusing everybody, so I'll try to explain
it clearly.  We're going to "merge" sablevm-classpath and sablevm into
one .tar.gz.  According to latest agreements and first tests (results
are in my sandbox) this "super-sablevm" tar.gz will actually contain
sablevm-x.y.z.tar.gz and sablevm-classpath-x.y.z.tar.gz plus a build
system with configure/Makefiles (from user POV it'd be just as natural
as the current system, with the difference that it'd require single
configure and single "make" invocation).  I see no reason why we could
not (at some later point) include "independant-libffi.tar.gz" into such
super-tarball of SableVM.  Note that this is much different from
including libffi code into sablevm itself.  (I hope I didn't confuse you
too much).

You know, this is like with Linux kernel.  The fact that something gets
merged in mainline does not necessarily mean it'll be always better
maintained.  There's many examples of things that got merged in Linux
and "died" and thing that have never been merged (because ex. they do
not "belong" to Linux kernel), but are well and alive.

On the organizational side, as I said before - we'll provide all the
necessary support, at least as good as SableVM itself has.

Great.  This might be something to start from.

*2*MB diff that puts libffi in SableVM? Ouch!



I took a quick look at the non-libffi part of your patche.  In general
our approach is to integrate all reasonable changes required
by ports, so that SableVM worked on them out-of-the-box.  (2MB patch
hardly qualifies as reasonable, at least at the first sight)

Would it be possible to separate the changes you really had to do to
SableVM (and SableVM Classpath - on which changes I haven't looked yet)
from the rest, so that we could see clearly what the changes were?

Such cleaned-up diffs would really be very helpful.  Given the amount
of great work you put in porting SableVM to Cygwin - why not have an
out-of-the box support for Cygwin in the official SableVM?  This is
somethings that surely "belongs" to SableVM proper.

Thanks for helping us so much,

Okay, but what /would/ be the right place? Since I don't think people

MinGW works greatly... And take GIMP as an example. You need sparate GTK 
package installed. Just like many new .NET apps needs .NET Framework 
installed - separately. Just to use _single_ application. Why does this 
differ from installing Cygwin? Execpt other is enforced and offered by 
Microsoft other by bunch of maniacs... (No offence =)

At the same time, however, we do not want Windows-based users to
feel forced into Cygwin's behaviours.  We want to distribute a
Windows application - GPL'd, with some Unix-style quirks, and
compatible to the other major OS'es out there, but Windows
nevertheless.
So maybe the MinGW project is more like what you're looking for, then.
Indeed; we're looking into it.

Be aware, though, that you won't get full POSIX functionality that Cygwin
provides -- only those parts that are directly supported by the MSVC
runtime.  In particular, you'll lose the ability to understand POSIX
(Cygwin) filenames.
There also exists GnuWin32 libraries that has very, very _minimal_ set 
of POSIX functions to make many libraries and applications to work.

Those who truly want a full Unix experience wouldn't use Windows in
the first place, and thus not Cygwin either.
This is not true at all (to put it mildly).  Those who want POSIX behavior
on Windows *will* (and *do*) use Cygwin.  But this particular point is
better ed.
Right, but I wouldn't define "POSIX behaviour" as "full Unix experience" ;-)

Hey, we're getting there -- see the efforts on porting Gnome to Cygwin...
Microsoft also offers "competitive" package, SFU that has, mainly libs 
for POSIX stuff. It doesn't contain all magnificent applications that 
Cygwin does, like X11 and SSH (which are great tools when used together.)

But yes, that's OT.

Yep.  A perfect topic for the cygwin-talk list... ;-)

printf output missing in multi-threaded program

[tfisher]

Hi, I am having the exact same problem as described below (I am
using cygwin on windows XP).  Corinna says (below) that it is fixed.
I have downloaded and installed several versions of cygwin including
the latest from "setup.exe" as well as recent individual snapshots
and the problem keeps occuring.  COuld you advise what release of
cygwin should be used.
Thanks alot.

That's what I get with a recent Cygwin snapshot:

Thread thr_wait: sleeping for 5 seconds.
Thread thr_fork: sleeping for 10 seconds.
Child process: I'm sleeping for 2 seconds.

Child process: terminating.
Thread thr_fork: 3 s of sleeping time passed
Thread thr_fork: 4 s of sleeping time passed
Thread thr_wait: try to wait for child process.
Thread thr_wait: child terminated.
Thread thr_fork: 5 s of sleeping time passed
Thread thr_fork: 6 s of sleeping time passed
Thread thr_fork: 7 s of sleeping time passed
Thread thr_fork: 8 s of sleeping time passed
Thread thr_fork: 9 s of sleeping time passed
Thread thr_fork: 10 s of sleeping time passed
Thread thr_fork: try to wait for my child.
Thread thr_fork: No child processes

Looks ok, doesn't it?

I should have added, "...in the context in question."  I though sure that
this was already tried, and whoever was doing it was unable to get a usable

even if I'm remembering correctly, I know not.

Re: Cygwin GMP 4.1.4-3 does not work correctly

[Gerrit P. Haase]

Hi Angelo,
in this case the bits precision is always a multiple of 30
(this is strange: one expect a multiple of a power of 2!)

4.1.3 and 4.1.4 were configured / compiled with the option:
  --enable-nails
Could you please compile your version with-nails and see if it is
'broken' in your version too then?
What is the option '--enable-nails' supposed to do?
Here is the docu: http://swox.com/gmp/manual/Low-level-Functions.html
[...]
At the mpn level, a nail build is neither source nor binary compatible 
with a non-nail build, strictly speaking. But programs acting on limbs 
only through the mpn functions are likely to work equally well with 
either build, and judicious use of the definitions below should make any 
program compatible with either build, at the source level.

For the higher level routines, meaning mpz etc, a nail build should be 
fully source and binary compatible with a non-nail build.

No, you don't.  You need

On the mailing lists devoted to such projects.  Or, you can ITP your
project for inclusion into Cygwin on the cygwin-apps list -- see
.

Be aware, though, that you won't get full POSIX functionality that Cygwin
provides -- only those parts that are directly supported by the MSVC
runtime.  In particular, you'll lose the ability to understand POSIX
(Cygwin) filenames.

Think Gtk for Windows programs (such as Gaim): they come with the proper

Cygwin is an emulation layer.  The Cygwin distribution contains a set of
packages that use this emulation layer.
 

Exactly - but where to discuss projects that use the emulation layer and

This is the right mailing list for discussing, say, problems building
something on Cygwin (if you think it's Cygwin's fault or some idiosyncracy
of Cygwin).

This is *not* the right list for discussing how to subvert the existing
Cygwin installations on users' machines by distributing your own copy of
cygwin1.dll (though this *has* been discussed in the past - search the
list archives).  If you're careful, you might even pull it off.

Cygwin is an emulation layer.  The Cygwin distribution contains a set of
packages that use this emulation layer.

That's one of the goals of Cygwin - to make porting Unix applications to
Windows easier.

This is not true at all (to put it mildly).  Those who want POSIX behavior

Top 10 Reasons Republicans Support Kerry

[[EMAIL PROTECTED]]

Republican Bill Shireman's Top 10 Reasons Republicans Support John Kerry

I'm a lifelong Republican, though I vote for the best candidate - or the
least objectionable one.  Four years ago, I hoped George Bush would be a
moderate, fiscally conservative leader, firm but thoughtful.  I have
been repeatedly disappointed.  My top 10 reasons for opposing George
Bush, and supporting John Kerry, are:

1. Stubborn is not Strong.   
2. You can't promote the Bill of Rights by violating it.  
3. You can't advance democracy by imposing it by force. 
4. Brave and Free, not fearful and insecure, are the qualities great
presidents inspire 
5. 30,000 deaths do not avenge the murder of 3,000 
6. Killing terrorists requires precise aim. 
7. You cannot protect 300 million rich by frightening 3 billion poor. 
8. In the military, Smart is as important as Strong 
9. Those who seek liberty through security lose both. Security is the
result, not the cause, of liberty. 
10. The "Last Resort" should be the last resort.

Some say Kerry and Bush are equally unacceptable.  That is a convenient
illusion.  Kerry has been an able, smart, capable, thoughtful
legislator.  He has demonstrated his heroism by placing his body in the
line of fire, to protect his men.  John Kerry will be a worthy resident
of the house Lincoln and Roosevelt once occupied.  

America is a great nation.  We need a fresh opportunity to demonstrate
that to the world.  I hope you will join me by committing your dollars
and sense to a cause to which many have devoted their lives.  

Join with me at:

A Republican I admire very much, former Congressman Pete McCloskey, says
it much better than I, at this site:  www.pacsatpost.com/mccloskey.

Re: Cygwin GMP 4.1.4-3 does not work correctly

[Angelo Graziosi (D. Zanello)]

Hi,

with the package gmp-4.1.4-1 I have the same problems that were present
with 4.1.3 and that WERE NOT present with 4.1.2!

I have downloaded the source gmp-4.1.4.tar.bz2 from
http://www.swox.com/gmp/
and have built it and uninstalled the Cygwin GMP package.
With this source, all works fine (as Cygwin package 4.1.2)!

The simple LiDIA-GMP application is:

//  LiDIA_picalc.cpp

#include 
#include 
#include 

#ifdef LIDIA_NAMESPACE
using namespace LiDIA;
#endif

using namespace std;

int main()
{
   int nDigits = 10;

   cout << endl
<< "Number of digits: ";
   cin >> nDigits;

   bigfloat::set_precision(nDigits);

   bigfloat x = Pi();

   cout << setprecision(nDigits) << endl
<< "PI = " << x << endl;

   return 0;
}

// 

With Cygwin packages it is built with

g++ -O3 -Wall -I/usr/local/include LiDIA_picalc.cpp \
-s -L/usr/local/lib -lLiDIA -lgmp -o LiDIA_picalc

(/usr/local is the directory where I have installed my builds
of LiDIA-2.1.2 and gmp-4.1.4 from http://www.swox.com/gmp/)



RESULTS with Cygwin packages 4.1.3, 4.1.4

Number of digits: 20

PI = 0.48602824728463545305e-4

Having paperwork on file with a custodian for a project has the benefit
of making sure the status of a project is not questioned now or in the
future. And that the copyrights can be enforced by that entity. We do
this also for GNU Classpath for example to make sure that every
contributer can, may and has actively consented to distribute his
contribution as free software. And that we have a record of who did what
and with the knowledge and assistance of any employers that might have
claim on what was produced by their employees. Cases like SCO-IBM
(unfortunately) make clear why that is a good thing to have.

That is bad. Lets try to get the missing patches merged in. There is a
mailinglist [EMAIL PROTECTED] to discuss this if there is
actual code that could be merged in.

This position seems not to have been enforced, as new ports and bug
fixes have been going in.  Usually Jim Wilson asks about the status of
the libffi stuff after the patch is already committed.

About the Windows port - were some patches missed?  I don't recall

Here is a script that I use over ssh.  It has not been exhaustively tested but
seems to work for the light duty I have put it through so far.  

Every now and then setup.exe seems to hang.  Since I'm logged in over ssh, I
can't tell if maybe setup.exe has put up a dialog and is waiting for user input.
 My normal response is to make sure the desired application has been installed,
and then give setup.exe a "generous" amount of time to finish up.  If it still
hasn't returned, I kill it.

The other caveat is that when you run this script, in addition to installing the
requested packages, it upgrades all of your packages to their latest versions. 
This may or may not be good for you.

And if you have a .sh file type handler to, say, be handled by cygwin/bin/sh,
then it squashes that, too.

Or if it is required to have a more recent mpfr version for this then we
could remove mpfr from the GMP package and build mpfr seperately.

Yes, but it's not Cygwin that's causing this behavior, it's your terminal
settings.

Yes.  'stty erase ^H'.  "man stty" for more info.

To put this on-topic, use the java wrapper scripts I posted a while ago
(they are also in the cygwin-apps CVS, under wrappers/java).  They contain
a "jar" wrapper script (which needs to be edited, hence it's not a package
yet) that understands Cygwin paths, etc.  So, basically, you'll need to
run

/usr/bin/find . -type f -a ! -name \*.pch -a ! -path \*CVS\* | /usr/local/bin/jar cvf@ 
../archive.jar

> Since we are not allowed to discuss jar here, is there a Cygwin utility that

Or just use the 'zip' utility from the 'zip' package (D'Oh!).

Again, /usr/bin/find . -type f -a ! -name \*.pch -a ! -path \*CVS\* -print0 | xargs 
-r0 tar cjvf ../archive.tar.bz2

'-print' is the default action.  You were missing the '-type f'

Ain't no such animal as 'gnuzip' -- did you mean 'gzip'?  'bzip' is a
patent-ridden ancestor to 'bzip2', and is rarely used these days (if at
all).  See, for example, the 'bzip' article at
 (the sixth match in a
Google search for 'bzip', BTW).

Quoting MSDN ():

A process can be associated with only one console, so the AllocConsole
function fails if the calling process already has a console. A process
can use the FreeConsole function to detach itself from its current
console, then it can call AllocConsole to create a new console or
AttachConsole to attach to another console.

So, basically, if there's another console, that console will be used.

Or, we could just call GetConsoleWindow() and check for a NULL returned

Could it possible to get a version of gmp compiled with --enable-mpfr
... or even better libmpfr 2.0.3 compiled and packaged seperately,
though it has a requirement to be built along with libgmp (The two
projects teams have split, gmp 4.x is distributed with the two year old
mpfr 2.0.1.  The next major release of gmp will not include mpfr at
all).

I have compiled and installed it on my own without difficulty.  

My main reason for requesting this is that GFortran 95, which will come
with upcoming GCC 4.0, requires libmpfr to build.  Furthermore, the
main GCC developers have been receptive to the proposal that all of GCC
4.1 be modified to use libmpfr for its internal math optimiziations
instead of its homegrown routines.

Not necessarily.  Have bash set the variable and 'exec' the shell -- and

Umm, as I said above, you can set the variable in the bash command, and
use 'exec -l' to spawn the shell.  As long as the startup scripts have to
recognize the variable anyway, they might as well do the 'cd'... :-)

  Ah, that'll be it.  Kinda OT now, but enough people read this list through
gmane to make it worth explaining: since you were replying to a new posting,
your reply went by both mail and nntp, with both a To: header and a
Newsgroups: header.  The mailed copy arrived at my inbox, and because it's
mail and outlook doesn't show full headers I didn't see the newsgroups
header.  Then when a copy did arrive (via gmane to the mailing list and then
on to me), it was dropped because I already had one matching that Msg-ID, so
I didn't see any copy with the list address in its headers.  Mystery solved.

[ANNOUNCEMENT] Updated: gmp-4.1.4-1

[Lapo Luchini]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

gmp-4.1.4-1 has been uploaded to the Cygwin net distribution.

Thanks go to Gerrit, who did *all* the work on this release.

Please notice gmp-4.1.3 had a serious miscomputation bug, upgrade to
gmp-4.1.4 is strongly suggested.

GMP is a free library for arbitrary precision arithmetic, operating on
signed integers, rational numbers, and floating point numbers. There is
no practical limit to the precision except the ones implied by the
available memory in the machine GMP runs on. GMP has a rich set of
functions, and the functions have a regular interface.

The primary source for information for gmp is:

  That's interesting to know: so there's only one part of RR that wants to
run in a unix world.   The term "nutc" refers to the "NuTCracker operating
environment" component, which it seems is a rebadged version of the MKS unix
environment[*], used by RR to support their tools.  This message:

Re: Ping: Cygwin libtool / assembler problem with -DPIC

[Gerrit P. Haase]

Yes, I know I'm annoying...

configure already checks for needed gcc options:

checking for gcc option to produce PIC...

So why don't go with it and use the option which is issued here from
configure?  What are all the tests good for if finally libtool overrides
it with its own flags?

Re: Ping: Cygwin libtool / assembler problem with -DPIC

Hi Charles,

yet another contra:

Don't mix things up.  `-f' is a command line switch for gcc/ld/whatever,
`-D' defines a macro and is not a command line switch to any tool.
You can think of it as counterpart of a `#define PIC 1' in any included
header and doesn't affect the behaviour of gcc/ld/whatever.

So IMO -D is completely in the user domain, just like CFLAGS, ASFLAGS
et al.  If libtool needs a flag internally to distinguish between shared
a non shared code compilation, then use another one, e.g. LT_DO_LO_NOW?

IMO the only relevant and also the only used flag on platforms where it
is needed is -fPIC?

Yes.  Well, what I'm really asking for is to make libtool better, i.e.
do s.th. about the fact that a defined PIC macro breaks assembler code
e.g. to disable the macro automatically when assembler code is to be
compiled with libtool.

problem with diff -I 'regexp'

[Le Dréau Philippe]

Hello :
My problem : I'd like to ignore the lines beginning with --
$ diff -I '^--' test1.txt test2.txt
1,3c1,3
< 1when
< --I want ?
< #ok nok
---
> 2when
> --I want
> #ok
5,6c5,6
< 2
< 3
---
> 4
> 5
8c8
< test 2
---
> test x

The lines are in the output, why ? I obtain the same thig with the following
similar commands :
$ diff -I '^#' test1.txt test2.txt
$ diff -I 'want' test1.txt test2.txt
Why the regular expression is ignore?

The input files :
test1.txt
1when
--I want ?
#ok nok
#end of comment
2
3
test 1
test 2

test2.txt
1when
--I want
#ok nok
#end of comment
2
3
test 1
test 2


A normal command produces :
$ diff test1.txt test2.txt
1,3c1,3
< 1when
< --I want ?
< #ok nok
---
> 2when
> --I want
> #ok
5,6c5,6
< 2
< 3
---
> 4
> 5
8c8
< test 2
---
> test x

An ignore option that runs (line 5 and 6 of the following disappear, that's
ok):
$ diff -I '^[[:digit:]]' test1.txt test2.txt
1,3c1,3
< 1when
< --I want ?
< #ok nok
---
> 2when
> --I want
> #ok
8c8
< test 2
---
> test x

Re: Distributing Cygwin-based software

That's possible, but see below.

The preferred option is to ask the user to install a standard Cygwin
installation from cygwin.com, using the Cygwin setup tool.  Then your
application can rely on the standard Cygwin install.

cygrunsrv is made as a tool to support a Cygwin installation.  cygrunsrv
itself requires the Cygwin DLL and it's designed to start Cygwin-linked
applications.  If you're going to install a service which is outside the
Cygwin installation tree, you can rely on the standard Cygwin install
to request some information.  E. g., the cygdrive prefix isn't hardcoded
to /cygdrive, but you can call `mount -p' in an installation script to
get the valid path prefix.

Probably openssl-devel.

  Yes, running *any* cygwin app will re-create the cygwin registry keys with
default contents if they don't already exist.

  Particularly mount, of course, since the main purpose of the cygwin
registry keys is to store details of mount points.

> Dunno.  Maybe this is just a weird PC.  I can't reproduce the problem.

  Yeh, I was starting to think we should just shrug and go "Musta been some
kinda bizarro transient h/w failure" unless you can find a way of repeating
it.

And I don't think so.  IMO all assembler code cannot be compiled on
Cygwin when you use -DPIC to compile it.  If libtool is used as it is
now, the compilation will fail, so libntool should care about this and
don't use this flag in case platform is Cygwin and compiling assembler
code.

Okay, after doing running the command:
mount
from the network-installed Cygwin, on the local machine the registry is
changed to have keys under HKCU and HKLM Software->Cygnus Solutions->
Cygwin->mounts v2->  (Default) REG_SZ (value not set).
I didn't think to check the actual value until after starting the next
test setup.exe run, at which point I noticed that there's also a
Software->Cygnus Solutions->Cygwin->Program Options that is the same:
(Default) REG_SZ (value not set).
But although the installation paused for a minute after the Download
phase, it's gotten past where it did before, and is happily installing
packages.
Dunno.  Maybe this is just a weird PC.  I can't reproduce the problem.

Re: Selectively zipping files together

[Brian Dessent]

Siegfried Heintze wrote:

The package name is "zip" and contains the info-zip code from
.  The commands are "zip" and "unzip".  Type
"zip -h" or "man zip" for usage.  I find it very bizarre that someone
could be familiar with the "find", "tar", and "jar" commands but never
have it occur to him to try "zip".

> Is it compatible with Windows zip?

A zip file is a zip file, it doesn't matter what platform the program
that created it was running under.  So, yes.  But you can verify this
yourself in about 20 seconds worth of work.

Probably because you're passing tar directory names in addition to
filenames.

And you shoudn't use the terminology "zipping up" because the tar file
format has nothing to do with zip.  I also noticed that in your example
you were having tar create a filename ending in .zip.  This is a very
bad thing to do - tar creates tar files, not zip files, and misnaming
the file as such will only cause confusion.  Don't confuse "tar" for a
compression program, it's not.  tar files are usually compressed
seperately with one of several compression methods (.tar.gz, .tar.bz2,
.tar.Z, etc.)

Re: Setup failure: mount error

luke wrote:
All this happened on a PC with no OS installed until I installed W2K.
The purpose was to test Cygwin.
So the very next thing (the only thing) I did was (try to) install
Cygwin.
But thinking about it last night, there was one other difference: I
created a file c:\cyg.bat that simply set PATH to include the directory
where I keep various helper Cygwin scripts (like the .bat to drive the
install via setup).
Perhaps that somehow got run by setup or by one of the post-install
scripts instead of some (internal) Cygwin command called "cyg"?
I can test both theories by trying to reproduce the problem.
Having c:\cyg.bat didn't make any difference - it still installed fine.
I've just removed Cygwin again, except for two files - cygwin1.dll and
bash.exe, since trying to remove them gave the error "access is denied".
(This is after checking that no bash process was running, via the 
Task\Manager; and no Cygwin services were running.)  Oh, and and of
course c:\cygwin and c:\cygwin\bin directories.

"Odd," I thought, and rebooted and deleted them following the reboot.
Anyway, the final experiment I can try now is to run "mount" from the
network install, and see it it makes Cygwin uninstallable again, without
a Windows reinstall.

Re: Ping: Cygwin libtool / assembler problem with -DPIC

[Gerrit P. Haase]

Hi Charles,
I just don't think it is good idea to use flags for s.th. else just
because they are there anywhere.  If there is need for anther special
flag then introduce it, exactly for this reason and this platform and
for nothing else.  DLL_EXPORT is the best example, if there is really a
need for another flag like this to be used like you described then
introduce one which is a flag that doesn't affect other tools like ld,
as, ar, 
PIC is the option to get position independent code where it makes a 
difference.  It makes no difference on Cygwin: so don't use the flag.

Problem with Cygwin reading/storing backspace character

[Maria Green]

Hi,

I program in C++ and have a problem while reading characters from the
stdin. Cygwin doesn't behave the same way as my Linux do and I don't know
if it's supposed to or not. I've searched the web for several hours but I
can't find any informtion about this so I will be very thankful for some help.

My problem
I use readline to read one line and store the characters in an array. If I
write something wrong and removes it with backspace, both the character
deleted and the backspace character is stored in the array as well. This
does not happen when you use Linux.

My questions
Is Cygwin supposed to behave like this? If so, is there anyway to make it
behave like Linux instead?


Cygwin version: 1.5.11-1
Operating system: Windows XP
Linux version: Linux Mandrake 10.0.

The code I used to test this:
int main()
{
 char text[] = {'A', 'A', 'A', 'A', 'A', 'A', 'A'};

 cin.getline(text, 7);


 //Print the whole string
 cout<(text[i])<<":";
 }
 cout
