This is question is about gnuplot, not cygwin, so is off-topic here.
You would do better to ask a gnuplot list.

Deprecating ntea

2007-02-28 Thread Corinna Vinschen
Hi,

I think it's time to remove the CYGWIN=ntea setting from Cygwin.
(see http://cygwin.com/cygwin-ug-net/using-cygwinenv.html)

The reason is that it's just a fake.  It fakes POSIX permission bits
by using the "extended attributes" capability built into NTFS.  it
also works on FAT by creating a bulky file in the root directory
of the partition.  Extended attributes were never implemented on FAT32,
so "ntea" could never work on FAT32.

So, IMO, ntea is not at all necessary.  Given that practically all
Windows systems nowadays are using NTFS and given that NTFS supports
real permissions, not only faked ones, I don't see any need for ntea.

I even consider ntea as dangerous, because it pretends a security
which doesn't exist.  That's what the default ntsec setting is for,
utilizing real permission settings.

Ok, that's my opinion, which should make it clear that I think
ntea is old cruft which should be removed from Cygwin.

My questions are thus: Does anybody seriously use ntea?  Do you think
you can't live without it?  Is using ntsec or just switching off
ntsec no option for you?  Why?  Or, to phrase it as I did on the
cygwin-developers list:

Does anybody have a good argument to keep this cruft against all reason?

Missing dependencies for qt3-devel

2007-02-28 Thread Rafal Mantiuk

Hi,

pkg-config file "qt-mt.pc" lists several libraries that are not
installed when "qt3-devel-3.3.4-2" is selected. The missing libraries
can be found in:

XFree86-lib-compat
xorg-x11-devel
minires-devel

It is quite difficult to figure out which packages are required, so I
would suggest adding them to the dependencies of qt3-devel.

Cheers,

Rafal

Regarding Problems with the mount command inside a script

2007-02-28 Thread Rakesh Kumar


Hello,

I'm running a command inside Cygwin

mount -b /cygdrive/c/cygwin/rakesh /cygdrive/c/cygwin/rakesh/usr/cygnus

But I get the following error…

mount: /cygdrive/c/cygwin/rakesh/usr/cygnus: Invalid argument

Is the mount command wrongly given??

Yes.  Take a look at "mount --help".  The first argument is a win32 path
-- that is the whole point of mount table entries, to map a win32 path
to a POSIX path.  And you should not be using /cygdrive like that. 
Assuming that c:/cygwin is mounted as /, then you probably want
something like

mount c:/cygwin/rakesh /usr/cygnus

In this case, you are better off looking in config.log, not configure, for

I've reported this upstream.  I also agree with Enrico's suggestion of
using . instead of a quoted space, since that is the regex character that
will match a space:

updatedb --prunepaths='/cygdrive/c/WINDOWS /cygdrive/e /cygdrive/d

Perhaps that was in distro-modified versions.  I just included updatedb as
it is upstream, plus a single patch to recognize that on cygwin, the
filesystem recognition code doesn't work very well.

I agree that directory name lists should look like a PATH, and not be

Sorry for the delayed reply; I was on vacation when this arrived.  I have
no idea what's going wrong here, but wonder if it is an issue with the
underlying readdir call.  At this point, an strace of the failure might
prove more informative as to what Windows is telling cygwin about the
contents of that directory.  But the strace is likely to be huge.  Maybe
Corinna has some more advice about what to look for?

Re: /dev/null timing and clock skew problems

2007-02-28 Thread Aaron Gray

It seems the 'Clock Skew' warnings are the only serious ones. They never
used to occur on previous Cygwin releases though.

I am building LLVM with Cygwin and am getting the warnings but on building
GCC I am getting no clock skew or modification time warnings.

   http://llvm.org

CVS and build instructions :-

   http://www.aarongray.org/LLVM/BuildingLLVMonCygwin.html

The clock skew warnings appear after a link or archive. I cannot seem to
find a flag for make to display executed commands though.

On my 1.4Ghz XP machine Clock Skews could be serious, but on my 1.6Ghz Vista
machine they appear not to be.

Could someone give me any idea when this will be fixed.

Many thanks,

Aaron

Re: Strange message from updatedb

2007-02-28 Thread Phil Edwards

Try replacing spaces ' ' with dots '.' in the paths specified with --prunepaths.
In a regexp a dot matches any character.


I had tried that, but
  --prunepaths='/cygdrive/c/System.Volume.Information'
still caused the corresponding directory to be searched.  I didn't have
time to look further then, maybe somebody else will beat me to it.

Which is exactly what I theorized above.  So, characterizing CTRL-C as

Now you know that you can use a standard console window for debugging
and all will be well.

Lacking the ability to interrupt a running program severely limits  
gdb's usefulness.  Fortunately there's a workaround available.

Yep.  Use a console window.



Is there a reason DebugBreakProcess can't be used from inside
gdb if sending a ctrl-c with GenerateConsoleCtrlEvent (CTRL_C_EVENT, pid)
doesn't work?

See gdb/win32-nat.c:win32_stop

and also:
http://sourceware.org/ml/gdb-patches/2007-02/msg00294.html
Look for win32_send_signal in the patch.

Note that DebugBreakProcess only exists on XP or Windows 2003
server onwards.  For WinNT < XP, it should be possible to simulate
it with CreateRemoteThread with entry point set to
DebugBreak or something similar.  The worst case would be that a dll
would have to be injected to load a function that does the
DebugBreak in the debuggee's address space.

I suppose that it could be used for that but it might be tricky figuring
out when it was required and when it wasn't.  You wouldn't want to
interrupt the process twice if it already saw the CTRL-C.  Although,
maybe if you used this you could tell the inferior process not to
process CTRL-C at all via some CreateProcess setting.

What about doing it the other way around?  Use DebugBreakProcess if
available, and fallback to GenerateConsoleCtrlEvent?  Is there anything
internal to Cygwin that uses it?  We could teach gdb that the next
BreakPoint inside kernel32 (, or whatever dll DebugBreakProcess breaks in,)
is mapped to SIGINT, remap the event, and switch to the main thread, so
the user doesn't see we stopped inside kernel32.

?  Maybe we're not talking about the same thing but I don't see why it
matters what the order of function calls is.  If the inferior process
has already responded to a CTRL-C you don't want it to get another
interrupt.

I think if gdb sends a break because it saw a CTRL-C and then gets a
break from the sub-process it is safe for gdb to assume that the
interrupt was a CTRL-C without needing to check where the break hit.  I
don't know about going to the effort of switching to thread 1, though.

Re: 100% CPU Usage and Error Message: Error, messageQ semaphore not equal to zero.

2007-02-28 Thread neo napster
Hi,

Thanks for your instant reply. I have a few queries regarding cygserver and 
cygipc. We have just started looking into our programs to see what the impact 
will be to move from cygipc to cygserver. 

1. Can you please give us an idea of the things that need to be done to move 
from cygipc to cygserver. Our programs are coded in C.

2. We were trying to just get the cygserver up and running. We have 
successfully installed cyserver. But, when starting Cygserver, the following 
error occurs:

"System Error 3 has Occured ---   The System cannot find the path specified".

I have checked services.msc for the cygserver service, it is installed 
correctly and the path to the exectuable is pointing to cygrunsrv.exe in the 
correct folder. What could be the problem?

Thanks and Regards,
Neo.

The last 1.3 release (1.3.22) is from March 2003.  The first time
Windows 2003 Server got supported was in Cygwin 1.5.0, back in May 2003.
Cygipc has been made redundant beginning November 2003.  It's February
2007.  The conclusion is this:  The software you're using is hopelessly
outdated and not supported anymore for a long time.

Update to the current release 1.5.24 and switch to using Cygserver
instead of Cygipc.  If you still have problems, feel free to ask this
mailing list for help.

Regarding mount command inside CYGWIN

2007-02-28 Thread Rakesh Kumar

Hello,

I'm running a command inside Cygwin

 mount -b /cygdrive/c/cygwin/rakesh /cygdrive/c/cygwin/rakesh/usr/cygnus

But I get the following error…

mount: /cygdrive/c/cygwin/rakesh/usr/cygnus: Invalid argument

Is the mount command wrongly given??

Regards,
Rakesh

Yes.

You need a win32 path for the mount source.

man mount.

-cl
