That's off-topic for this mailing list because it's not Cygwin
specific.  This is not a list about how to program in C, there are
plenty of those elsewhere.

Well, I've just tested this myself, and the only error I get is the 
normal permission denied on system volume information.
I should mention that I updated my cygwin installation on Thursday or 
Friday last week..


There are two things I'm wondering though...
Where is this . in your PATH coming from? (it's in your cygcheck output)
Also, have you tried making the /cygdrive/X mounts binmode?
Mine show up in mount like:
c: on /cygdrive/c type system (binmode,noumount)

Might be worth testing it that way?

Subversion client & text mounts

[Jörg Schaible]

Hello Subversion maintainer,

the subversion client does unfortunately not respect text mounts. Checking out 
form a remote repository all text files have unix line endings although they 
have the property svn:eol-style set to native. This is a major hassle in a 
build environment where also a lot of non-Cygwin tools have to be used.

This definition is missing up to 1.5.18 but has been added to Cygwin
in CVS already.  Try the latest snapshot from http://cygwin.com/snapshots/

Other than that, raw sockets are not officially supported, but it should
basically work.

zsh as login shell

[Com MN PG P E B Consultant 3]

I would like to have on my Windoze desktop an Icon for zsh running under

Cygwin, similar to the standard Cygwin Icon which runs a bash login
shell,
so that I can choose whether to get a window using bash or using zsh.

It works kind of, but I can't get zsh executed as login shell. The BAT
file
invoking the bash login shell calls bash using

  bash --login -i

but zsh has no equivalent to the --login option, so I just use

  zsh -i

which makes the shell interactive, but not login. Zsh considers itself a
login
shell iff it is called under a name starting with a dash.

Is there an elegant solution to this problem? Of course I could

  cp -- zsh -zsh

and call -zsh, but I would have then to redo this everytime I update zsh
to a 
newer version. Another possibility would be to execute a shell script
using
bash and in this script do an

  exec -a -zsh zsh -I

But maybe someone knows a better way to do this?

File permission problems with setup.exe

[Alexander Gottwald]

Hi all,

Updating cygwin two days ago revealed two problems with cywings setup.exe

1) corrupted /etc/setup/.lst.gz 

setup tries to read the file and stops. The error message in the logfile
did not mention the filename. Deleting the broken file solved the problem

2) insufficent file permissions 

A folder had 0700 permission for my user account and installing as admin
user hang when setup tried to write a file to that folder. It printed 
log messages continously and ate up all memory.

See script below sja.exe is actually in program files, my kludge below was to 
use a mount (rather
than the short name)

(sja.exe is SQLYOG Job Agent)

dirbackup="c:/backup/dosh/"


eval filedate=$(date.exe '+%d%b%y')

ls -l c:/backup/dosh/doshautoexport.sql

sjaprog="/sqlyog/sja.exe"
sjascript="c:/cygwin/usr/local/bin/sql/dosh-batch.xml"
sjarun="$sjaprog $sjascript";
$sjarun

Considering all this is doing is launching a statically located 
executable with a statically located script (xml) file, this seems 
overly complex..
Surely you could just do /cygdrive/c/Program\ Files/sqlyog/sja.exe 
c:/cygwin/usr/local/bin/sql/dosh-batch.xml ?
One question.. When you were trying with spaces.. Did you try escaping 
the \ ? (as in Program\\ Files)
I've found this to be necessary at times, though I can't remember an 
instance at the moment.
Does the command run from the console if you start it using the standard 
path?

I don't see anything here that necessitates using a mount or 8.3.

> sjaprog="/sqlyog/sja.exe"

sjaprog="/cygdrive/c/program\ files/whatever/sja.exe"

> sjascript="c:/cygwin/usr/local/bin/sql/dosh-batch.xml"

"$sjaprog" $sjascript

OR

sjarun="\"$sjaprog\" $sjascript"
$sjarun

I fail to see the need for the variable $sjarun if its only function is
to be the command that's executed on the next line.

Brian has suggested a more versatile method. Use it instead.
But both of us have indicated that we can't see the point in the sqlrun 
variable (I don't particularly see the benefit of any of them over say, 
an alias in your bashrc).

Re: Problem: find not traversing /cygdrive/X properly?

[Kevin Autrey]

Hi Chris -

I always put "." in the front of my path so that as I'm developing an app, 
I always pick up the devel version in my current working directory instead 
of /usr/local/bin.  I know it's not the most secure thing in the world, but 
I'm on a stand-alone, single-user system, so the security risks are manageable.


Just to try something, I modified my path to only include "/usr/bin" - no 
difference:



tka-16:/cygdrive/p> set path = "/usr/bin"
tka-16:/cygdrive/p> which find
/usr/bin/find
tka-16:/cygdrive/p> find /cygdrive/c -iname win.ini
find: .: No such file or directory
find: /cygdrive/c/.backupSettings: No such file or directory
find: /cygdrive/c/AUTOEXEC.BAT: No such file or directory
find: /cygdrive/c/boot.ini: No such file or directory
find: /cygdrive/c/CONFIG.SYS: No such file or directory
find: /cygdrive/c/Documents and Settings: No such file or directory
find: /cygdrive/c/IO.SYS: No such file or directory
find: /cygdrive/c/Log.txt: No such file or directory
find: /cygdrive/c/MSDOS.SYS: No such file or directory
find: /cygdrive/c/NTDETECT.COM: No such file or directory
find: /cygdrive/c/ntldr: No such file or directory
find: /cygdrive/c/PRIOR_SYSTEM: No such file or directory
find: /cygdrive/c/Program Files: No such file or directory
find: /cygdrive/c/RECYCLER: No such file or directory
find: /cygdrive/c/System Volume Information: No such file or directory
find: /cygdrive/c/Temp: No such file or directory
find: /cygdrive/c/tomsteady.ini: No such file or directory
find: /cygdrive/c/WINDOWS: No such file or directory
find: /cygdrive/c/xPos.txt: No such file or directory



Per Eric's suggestion from last week, I did change my mount types to -b:


tka-16:/cygdrive/p> mount -m
mount -f -s -b "D:/CygWIN/bin" "/usr/bin"
mount -f -s -b "D:/CygWIN/lib" "/usr/lib"
mount -f -s -b "D:/CygWIN" "/"
mount -s -b --change-cygdrive-prefix "/cygdrive"


Very strange...

How exactly would this work? After all, we are talking about Windows
Batch skripts,
don't we? And they are not aware of /etc/passwd. 

But maybe I didn't get your point. How do you suggest that I should
modify my /etc/passwd?

Please attach the script in question verbatim (ie don't edit it) so that

Obviously, if there are passwords, or server names, or ip address, you 
can mask those..

Just don't change the script itself.

Hi Chris -

I always put "." in the front of my path so that as I'm developing an 
app, I always pick up the devel version in my current working directory 
instead of /usr/local/bin.  I know it's not the most secure thing in the 
world, but I'm on a stand-alone, single-user system, so the security 
risks are manageable.


Fair enough. Just seemed odd (I didn't think for a moment it could cause 
the problem.. Just out of place).




Just to try something, I modified my path to only include "/usr/bin" - 
no difference:



tka-16:/cygdrive/p> set path = "/usr/bin"

Per Eric's suggestion from last week, I did change my mount types to -b:


tka-16:/cygdrive/p> mount -m
mount -f -s -b "D:/CygWIN/bin" "/usr/bin"
mount -f -s -b "D:/CygWIN/lib" "/usr/lib"
mount -f -s -b "D:/CygWIN" "/"
mount -s -b --change-cygdrive-prefix "/cygdrive"


Could you paste the current output of mount ?

characterse into $foo.  Until you have the correct contents in $sjaprog,
then invoking "$sjaprog" will fail.  If you really want 4 characters in
$foo, then you need an eval to reparse the expansion.  Learn how to
properly use shell quotes - it will save you loads of headaches.

No, it doesn't.  I just tried it in 6.3 and this behaviour is the same
as in 6.4.  There is special code in the native Windows port which tests
explicitely for the case of the filename, but that's not in the UNIX
code which is used for Cygwin.

Er... isn't that pretty self-evident?  You should just be prepared to use

Maybe, but http://cygwin.com/acronyms/#SHTDI.  A patch which optimizes
cases like this are always thoughtfully considered.  If you're willing
to help, have a look on http://cygwin.com/contrib.html.  However, I'd
think we shouldn't change this for the upcoming 1.5.19 release which
already contains a lot more changes than we had in mind once.

There's double quoting now.  My email wasn't quite correct, use one or
the other but not both:

foo=/path\ with\ spaces

or

foo="/path with spaces"

and then when you want to use $foo as a single word, use double quotes,
as in:

"$foo" arg1 arg2

overlapping windows in cygwin

[Fabrizio Salvatore]

Hi,

I've just installed the latest version of cygwin, that I use to connect 
from my WindowsXP laptop to our linux farms at the university. I run 
startxwin.bat (as a shortcut from my desktop) and, from the cygwin 
terminal window I then jump to wherever I need to. My startxwin.bat is 
the default one that comes with the cygwin installation:


SET CYGWIN_ROOT=\cygwin

SET PATH=.;%CYGWIN_ROOT%\bin;%CYGWIN_ROOT%\usr\X11R6\bin;%PATH%

SET XAPPLRESDIR=/usr/X11R6/lib/X11/app-defaults
SET XCMSDB=/usr/X11R6/lib/X11/Xcms.txt
SET XKEYSYMDB=/usr/X11R6/lib/X11/XKeysymDB
SET XNLSPATH=/usr/X11R6/lib/X11/locale

if not exist %CYGWIN_ROOT%\tmp\.X11-unix\X0 goto CLEANUP-FINISH
attrib -s %CYGWIN_ROOT%\tmp\.X11-unix\X0
del %CYGWIN_ROOT%\tmp\.X11-unix\X0

:CLEANUP-FINISH
if exist %CYGWIN_ROOT%\tmp\.X11-unix rmdir %CYGWIN_ROOT%\tmp\.X11-unix

run XWin -multiwindow -clipboard -silent-dup-error

run xterm -fn 6x13 -g 140x24 -si -sk -sb -fg black -bg Wheat -T "cygwin 
terminal Window" -e /usr/bin/tcsh -l


I'm simply using Windows as my window manager (not running twm or fvwm 
or anything like that); when I have several windows, I would like to 
focus on each one of them (and so activate them) by just pointing my 
mouse to the window, instead of clicking on them. Does anyone know if it 
is possible (and in case how to do it) ?


I also noticed that for some graphical programs (like PAW, for example, 
the physics analysis workstatio developed at CERN), when an xterm window 
is overlapped to the graphics window, the part of the plot that is 
covered by the xterm is cancelled and when I focus back to the graphic 
window (by clicking on it) my plot is partially deleted. Any idea why 
this happens ?


Many thanks for any help/suggestion !

Looks like the cygdrive prefix takes precedence over explicit mounts.
This is arguably a bug.  .
Corinna or Chris, care to comment?

To do this under Cygwin also requires adding a kernel module -- which
makes sense once you realize that the Cygwin kernel is essentially Windows
(plus cygwin1.dll).  If you add a virtual serial port under Windows (see
MSDN for instructions), Cygwin should be able to use it.

As Brian pointed out, you don't have a mount table.  AFAIK, for Windows to
be usable at all, at least the user registry should be writeable, so
nothing prevents you from adding user mounts.  Try

mount -u -b f:/tools /
mount -u -b f:/tools/bin /usr/bin
mount -u -b f:/tools/lib /usr/lib
mount -u -b c:/temp /tmp

(the first three are needed for Cygwin to function properly, the last one
can be changed to point to a local directory that you have write access
to, unless you want a shared /tmp).
HTH,
Igor

The latter sounds like the best solution.  You could do it directly from
the batch file by using

bash -c 'exec -l /usr/bin/zsh -i'

RE: Cron Problems with Cygwin

[CWS Informatics [Sas]]

I am not sure what else you want based on reporting guidelines. I
attached the cygcheck file though.

As for what I am trying to do: 

We have a bunch of old Unix scripts and software that we need to keep
running for awhile. 
These need to run every x minutes for y range of hours during the day.
The scripts and software produce the results we are looking when run
from the command line in Cygwin. 

There is nothing but "Cron Started []" in the cron log.

Thank you.

Please read and follow the problem reporting guidelines found at:

Configuration information and details of what you're doing would also be
helpful.

You may find more info in '/var/log/cron'.

Why don't you try it, consultant?! There's actually just a single

It is available as part of the normal cygwin distribution.
You can get instructions for installing cygwin at:

  http://cygwin.com/cygwin-ug-net/setup-net.html

During the installation process, you will want to make sure that
you select the "mtd" package for installation.  This package is
part of the "Devel" category.  Once you have cygwin and the mtd
package installed, you should be able to use mkfs.jffs2.

Read the bash man page on input redirection.  This is not how you redirect
input in the current bash process.  Using

exec 3<"$HOME/bin/h"
while read -u 3; do echo $REPLY; done

works just fine for me.  Note that you may want to quote $HOME...

Thanks for the clarification, Thorsten.  As I don't know anything about
using zsh, I was suggesting a way of modifying cygwin.bat appropriately.

The above method could be used for shells that don't understand --login
(e.g., ash) or those where using the --login flag is inconvenient (e.g.,
when you want to pass more options to a tcsh login shell).

cygwin-setup & rebaseall

[Satish Balay]

I don't see any FAQ regarding rebaseall - hence this post.

It appears that rebaseall is required ocassionally to get cygwin [esp
python] working. [having been bitten by this a few times,] Each time I
do any cygwin updates - I make sure I run 'rebaseall' before doing
anything else.

Q: Does cygwin setup run rebaseall either during initial install or
during subsequent updates? [guessing no]

Q: Is it safe to say: 'if cygwin is installed from scratch - rebaseall
is not required'

[for our tools] cygwin/python is a pre-requisite - and our users
appear to stumble across this issue regularly. And asking users to
always run rebaseall is an extra hurdle]

Thanks,
Satish

My name doesn't start with C, but I will comment that if the precedence
went the other way, a mount like:

  mount c:/foo /cygdrive/d

would make a windows path d:\bar have no posix translation.

You should add the option '+bs' when starting XWin, i.e.:

 run XWin -multiwindow -clipboard -silent-dup-error +bs

(This results from PAW-All-FAQ)

Re: zsh as login shell

On Mon, 24 Oct 2005, Com MN PG P E B Consultant 3 wrote:

Greetings, Ronald,


I would like to have on my Windoze desktop an Icon for zsh running under

Cygwin, similar to the standard Cygwin Icon which runs a bash login
shell, so that I can choose whether to get a window using bash or using
zsh.


Use mkzsh to do this.  For help, type 'mkzsh --help'

eg:

mkzsh --desktop


It works kind of, but I can't get zsh executed as login shell. The BAT
file invoking the bash login shell calls bash using

 bash --login -i


See the '-l' option of zsh in the manpages.

eg:

zsh -l


but zsh has no equivalent to the --login option, so I just use

 zsh -i

which makes the shell interactive, but not login. Zsh considers itself a
login
shell iff it is called under a name starting with a dash.

Is there an elegant solution to this problem? Of course I could

 cp -- zsh -zsh

and call -zsh, but I would have then to redo this everytime I update zsh
to a
newer version. Another possibility would be to execute a shell script
using
bash and in this script do an

 exec -a -zsh zsh -I

But maybe someone knows a better way to do this?

How is this different from

mount c:/baz /somemount
mount c:/foo /somemount/d

(except for the fact that /cygdrive/d is an automount)?  I'm actually not
sure what's meant by "posix translation" in this context...

No, setup has no clue about rebaseall.

That's not quite correct.  Whether a rebase is required depends on
several factors - which packages you've selected, and whether those
packages have been compiled with --enable-auto-image-base.  As you have
noted, the rebase is only required for certain packages, particularly
those that use dynamically loaded modules such as python or perl.  Many
people use Cygwin all the time and never run into the problem because
most programs don't suffer from this.

Additionally, maintainers of these packages have (I believe) recently
started compiling them with --enable-auto-image-base which should
eliminate (or reduce) the need to rebase.

> [for our tools] cygwin/python is a pre-requisite - and our users

Always running rebase after any setup operation seems like overkill.  It
should only be necessary if you upgrade python or a dynamic library that
python might load at runtime, and then only if python wasn't compiled
with the above flag -- I don't know the current status of which
maintainers are doing that.

So, it seems to me like it would be a lot easier just to say "Run rebase
if you get an "Unable to remap" error" instead of "Run rebase
religiously after any setup operation."  Or, if you know that python
triggers this problem then perhaps it should be, "Always run rebaseall
after a clean install, and then don't worry about it again unless you
get the "unable to remap" error."

For example, assume a windows PATH=d:\bar.  What does a cygwin program
convert PATH to at startup?  There would be no equivlent, since
/cygdrive/d/bar would mean c:/foo/bar, not d:/bar.

Here's a success story:

correctly on a brand new installation on XP Home (cygrunsrv reports Win32
error 1062, but the sshd process starts nonetheless).  The latest snapshot

Ah, I see.  Well, one solution is to disallow mounting over directories
under the /cygdrive prefix (which is a good idea anyway, as it'll wreak
havoc even in the current case).  Yes, I know, PTC...

Thanks.  I was also looking for details about your failing cron commands.


As for what I am trying to do: 


We have a bunch of old Unix scripts and software that we need to keep
running for awhile. 
These need to run every x minutes for y range of hours during the day.

The scripts and software produce the results we are looking when run
from the command line in Cygwin. 


There is nothing but "Cron Started []" in the cron log.



So it sounds like cron thinks everything is fine.



Thank you.



OK, then let's go back to basics.  Clear your crontab out of everything but
the following line:

1 * * * *   /bin/echo "hi" >/tmp/cron.out

Do you get a /tmp/cron.tab with "hi" in it after a minute?  If so, then you
need to look at your originalcrontab commands and figure out which ones
are causing you the problem.  From the output, it would suggest that you're
invoking 'cmd' for something.  That may be causing you some problem.  If
you don't get any output with the simple crontab file, you probably want to
uninstall and reinstall the cron package, reading
'/usr/share/doc/Cygwin/cron.README' immediately after installing.

problem with sendto and raw sockets

[Fernando Barsoba]

Hi all,

I'm stuck trying to send an IP header through raw sockets. I'm using 
Eclipse and cygwin.. but I have been told that raw sockets should work 
with cygwin.. I got the definition for IP_HDRINCL from the last 
snapshot. I only got the socket.h header file from the snapshot... and 
not the whole thing. I have been able to build the program, but I am not 
sure if using only the socket.h could be the problem...


The error that I get back is: Cannot assign requested address.

Here's my code. I have been trying with this implementation using raw 
sockets and I have the same problem -> http://www.whitefang.com/rin/

(rawsock-05)

Any help appreciated.. i'm stuck with this thing..

Using a modified header with the old 1.5.18 cygwin1.dll is probably
going to be a bad idea.  The snapshot dll and headers are meant to be
used together.

Hmm...I think I see what you're getting at.  I'm (obviously) not really all that
knowledgeable of serial ports under Cygwin.  I was quite shocked actually that I
could just open "COM4" and write to it and it seemed to work OK

so...If I open "COM4" from cygwin, cygwin thinks I'm really just opening
some disk file..and probably all I can do is read/write..and perhaps even that
might not be totally reliable.  If I use /dev/com4 (or /dev/ttyS3), then the
underlying software understands that I am actually opening a serial port, and
all of the things like baud rate, parity, start, stop bits..etc..can all be
configured correctly...and there is probably a lot more testing that goes into
making sure /dev/com4 works properly.

Thanks to Brian for bringing it up, and thanks to you for the clarification.  I
was missing the point that COM4 is NOT the right way to access serial port #4
under cygwin.  It's easy enough to change...

Currently the burden is on [cygwin] users to know/keep track of this
info. And not all instructions/documetation get read by users. So each
time there is such a breakage, cygwin get a bad repo [why doesn't it
just work?]

So I hope cygwin can improve on this. Users seeing "Unable to remap"
errors [however infrequently] should be avoided - esp if it can be
automated.

[maybe the fix is: for any package that is likely to break - add a
flag - which triggers setup to run rebaseall - after
install/upgrade. So no overhead for pacakges that don't break - but
always overhead for packages that break.]

Thanks,
Satish

That message was for a much older configuration.  Perhaps the issue has
been fixed since then, but since you did not attach cygcheck.out for us
to determine your configuration, I can't tell if you need to upgrade.

If I understand right, cygwin uses assembly instructions that won't work
on a 386.  But beyond that, if you have a machine that can run Win95,
then you can run cygwin (although it may be painfully slow).  I
regularly run cygwin on a 266 MHz Pentium Pro, Win98 (although I much
prefer more modern machines).

I don't know if Jason has started compiling Python with
--enable-auto-image-base or not.  It will also depend on the maintainers
of any libraries that are dynamically loaded by a python module using
the flag as well.

This is true.  It is a rather bad situation.  It is mitigated by the
fact that it only affects certain packages used in certain
circumstances.  Cygwin is also somewhat aimed at users that are familiar
with reading documentation, and this problem is documented in
/usr/share/doc/cygwin/python-*.README.

It's not that simple.  The --enable-auto-image-base feature is, in
theory, the correct way to fix this problem.  This option has been
traditionally been disabled by default, for reasons I'm not familiar
with.  At some time in the past I think it had some problems.  And I
seem to recall that it can still cause conflicts in certain
circumstances because Cygwin uses a small amount of memory past the end
of the DLL for record-keeping purposes, which the rebaseall script
accomodates by adding padding.

Automatically running rebaseall from setup.exe has issues too.  For one
thing, it would run into problems if the user had programs or services
running.  The rebaseall script bails if it cannot write to a DLL, so
unless the user was very careful to close all running programs, it would
fail in almost all cases.  Rebaseall would have to be modified to rebase
in-use DLLs, but this would require the user to reboot.  And, somehow
this would have to be communicated to setup.exe so it could notify the
user.  Plus, consider if setup.exe installed a DLL that was in use
(writing it to name.dll.new, and scheduling that for replacement at next
boot) and then rebaseall was run.  The rebaseall script would have to
know to rebase name.dll.new and not name.dll.  It just gets more and
more complicated.  The only workable solution would be to incorporate
the entire rebaseall functionality internally into setup.exe, which is
not an insignificant undertaking, and one which no one is eager to
undertake.

On top of that, there is a problem with running out of address space.  I
don't think this happens (yet!) with the official packages but someone
has reported that it can happen if you suppliment an installation with
some of the Cygwin ports like KDE.  So this solution of rebasing every
single DLL is clearly not scaleable into the future, unless the Cygwin
DLL's memory layout is rearranged, or unless DLLs are rebased into
another memory space.

Thank you, this works equally well.

I had searched the manpages for this option, but overlooked it...

I do normally also, but I have now the need to work on binary and on text

Not any text file may have svn:eol-style=native. So this is not an option.
