Snapshot heads up for 20060301 2310 version

[Karl M]

Hi All...

With the latest, if I do a

cd /

my bash window disappears. I haven't had time to explore further. 20060227 
works fine.


Thanks,

...Karl

compiler option

[Basavaraj Hiremath]

Hi,
I am compiling a file(strerror.c) with following
option
-bash-2.05b$ arm-wince-pe-gcc -mcpu=xscale -c -ansi
-D__stdcall= -D_OFF_T_ -DHA
VE_CONFIG_H -I/usr/local/wince/cross-tools/include 
-I. -I./../include  -W -Wal
l -Wtraditional -pedantic  ./strerror.c -o
pic/strerror.o


It's giving following compilation error
/strerror.c:626: error: expected identifier or '('
before string constant
/strerror.c:628: error: expected identifier or '('
before '{' token



file strerror.c has following function

char *
strerror (errnoval)  -> line 626
  int errnoval;
{--> line 628
  const char *msg;
  static char buf[32];
---
-
}


Could somebody tell me, what is the compiler option to
go pass thru this kind of implementation?


Thanks in advance
Raj

You are compiling a K&R-style C function header in ANSI mode -- of course
you're getting an error.  Either remove the -ansi flag, or fix the file to
use ANSI-style declaration.

Google for "k&r ansi" for innumerable resources on this.  Oh, and this has
nothing to do with Cygwin.

[Newbie] Installer Question

[Michael Banks]

We have developed a product for the medical industry, which makes use of a few 
of the open-source cygwin tools (like, grep, find, etc.). The problem is that, 
believe it or not, many doctors' offices do not have an Internet connection, so 
installing cygwin via the downloadable setup program isn't a viable option

I think ideally we would build a single installer that includes our 
closed-source product, the needed open-source cygwin tools, and the full 
sources of cygwin. How exactly do we include the proper cygwin files, so that 
we're in compliance with the licensing? If we do a sample cygwin install on a 
PC, does the cygwin folder contain everything we need (open-source tools + 
cygwin source), or is it more complicated than that?

Why don't you set up a mirror on a portable and 
just plug it into the target computer, install Cygwin,

around there is a patched version of lucida console (called "lucida

Re: cygwin scp -r fails

[Dale]

I confirm the failure.  Also, the 20060301 snapshot works for me.

"scp -r" worked OK for me with cygwin-1.5.18-1.
"scp -r" silently failed with cygwin-1.5.19-4.
I was able to make the problem come and go by copying old or new
cygwin1.dll into /bin.

"scp -r" again works for me with the snapshot from

'Missing isnand' still not fixed in 2006-03-01 snapshot

[Jerry D. Hedden]

Using the full (inst) 2006-03-01 (23:10 GMT) snapshot, I'm still getting
these errors when building Perl:

/c/perl_tmp/perl-5.8.8/libperl.a(pp.o):pp.c:(.text+0x643b): undefined
reference to `___isnand'
/c/perl_tmp/perl-5.8.8/libperl.a(pp.o):pp.c:(.text+0x64f2): undefined
reference to `___isnand'
/c/perl_tmp/perl-5.8.8/libperl.a(pp.o):pp.c:(.text+0x6506): undefined
reference to `___isnand'

Is there something else I need to download/fix/modify?

Nope, the cygutils website was relocated to 
http://cygutils.fruitbat.org/ thanks to the generosity of Peter Castro. 
 Not much happening there; it was rendered largely obsolete once I got 
most of my stuff ported to the cygwin packaging system in (what? 2000?). 
 However, luconP.zip still lives there, at


http://cygutils.fruitbat.org/bashprompt/index.html

Strangely, if I set TERM=rxvt-cygwin-native , use luconP as my font , it 
does NOT matter whether my CYGWIN variable has codepage:oem, 
codepage:ansi, or neither.  The following behaviors are the same:


ascii.exe prints the line draw characters
pstree -G prints garbage

It *could be* due to the fact that pstree uses ncurses, and ascii does 
not.   Checking...


Hmmm.  /usr/lib/ncurses/test/ncurses.exe (part of the ncurses-demo 
package) turns the screen black-on-black when I try to check the 
line-draw characters.  So I can't even tell if ACS chars with ncurses is 
broken -- first I gotta figure out why the colors are getting scrogged 
by the test program!  Somebody, like the ncurses maintainer, should fix 
that.


Oh.  That'd be me, then.  Ooops.  I'll try to look into it soon, but PTC.

Did you install the whole snapshot, or just the DLL?  Some of the changes
were probably to the header files, which need to be installed too.

cygwin-inst-20060301.tar.bz2 where 'cygwin-inst-*.tar.bz2 = directory

RE: OpenSSH for Non Administrators

[Siegfried Heintze]

I looked in http://www.openssh.com/faq.html#1.1 as reference by
c:/cygwin/usr/share/doc/openssh/README and I'm having trouble finding the
document that explains how to set ssh up as a service on a windows server.
Can someone please point me to the correct document?
c:/cygwin/usr/share/doc/openssh/README said to refer to the INSTALL document
but I see no such in c:/cygwin/usr/share/doc/openssh. Is my installation
incomplete?

There seems to be a lot of information in "man sshd" and "info sshd" but I
could not find where it explains to start it up as a service. No wait: it
says it is normally started in /etc/rc but my cygwin installation has no
such directory. Don't I have to do something with cygrunsrv or some such
utility? Where is the documentation on ssh-host-config that Damian is using
below? I tried man and info with no luck.

Can cygwin ssh be used with the -X option to open an X session on a windows
server? 

Can cygwin ssh be used with VNC to open a VNC session on a remote server? I
have successfully open a session using plain "RealVNC" server on the windows
server (from red hat 8) and would like to do it securely with ssh.

Thanks,
Siegfried

I'm guessing this is your problem right here.  Which user did you do this
as?  If you did this as yourself, it could be that these files are only
readable by the Administrators group, which explains why those users can
log in.  Either those, or some other file needed for the login...
Perhaps the shell (/bin/sh or /bin/bash)?

What does "ls -l /etc/{passwd,group} /bin/sh /bin/bash" print?

I don't know that gcc has an option to accept such non-standard code.  I

Printing man pages

[George]

Generating a PDF from the grep man page, for example, using:

   man -t `man -w grep` | ps2pdf - grep.pdf

which, by default, is actually

   /usr/bin/groff -Tps -mandoc `man -w grep` | ps2pdf - grep.pdf

results in a fairly unattractive PDF file.  The man page title is
dropped from the output, and the top margin is borked.

On the other hand, using

   /usr/bin/groff -Thtml -mandoc `man -w grep` > grep.html

yields something more satisfactory, but not in a format for printing.

I'm finding that reading through the groff man page(s) is like
[obligatory hippo joke], so I'm hoping I'm missing something obvious.

Thanks.

That won't work.  Cygserver's IPC functionality can only function
correctly with Cygwin applications.

Syncronizing Windows users and cygwin useres automaticaly

[Mair, Paul]

Hallo,
I'm using cygwin and Windows Server 2003.
Is there a possibility to synchronization of the Windows user and the cygwin 
users automatically on the creation of the Windows user without typing mkpasswd 
-local > /etc/passwd.
Or exists a possibility to create a user into cygwin that is than automatically 
createt in Windows.
Thanks for any suggestion
Paul

  Hmm, I wonder if this is what's been making some of my windows start
randomly popping to the front while I'm running a big complex build from bash
in a minimized DOS console involving multiple instances of processes launched
from bash and cmd.exe shells?

  Nope, but I'll perhaps try and figure one out when I get a spare moment.

  Precisely which package is it?  And are you trying to get source as well as

Cygwin problem with cross compiler

[Basavaraj Hiremath]

Hi,
I am not able to compile "Hello World" program
using this compiler in CygWin Environment, but I am
able to compile in Redhat linux enviromnet.

"arm-wince-pe-gcc foo.c" -> does't
work(/usr/local/wince/cross-tools/bin/arm-wince-pe-gcc:
/usr/local/wince/cross-tools/
bin/arm-wince-pe-gcc: cannot execute binary file)

Even if I type
> arm-wince-pe-gcc --v, it give cannot execute binary
file.

am I missing any packages from cygwin?
I have installed win32api package as well.

Thanks in advance.

  Cygwin doesn't actually let you run Linux executable binaries on windows
directly, you have to recompile them from source code - cygwin's job is to
make that step easy by providing all the headers and libs and function calls
that Linux executables need to have provided in order to compile.

Re: problem with starting services in 1.5.19

[Yadin Y. Goldschmidt]

Attention Chris and Corinna
I narrowd the problem down to one snapshot. The sevices start fine on the 
12/27/05

snapshot and don't start on the 12/29/05 snapshot.
I noticed that there were extensive changes by Chris on 12/29 so I have
no idea what change is responsible for this. Maybe you can sort this out.
Yadin.
"Yadin Y. Goldschmidt" wrote in message news:[EMAIL PROTECTED]

Thank you Corrina for your answer although you did not offer a solution.
The problem is very similar to problems Igor Peschansky and others
had in the past with XP SP1, apparently because of changes made on 01/04 
concerning
fhandler_console? I run SP2 but I still have a problem. If I only run one 
service on
reboot it will start but if I try to run 2 services on reboot one would 
hang.

From the command line none will start. There is nothing in cron.log
or sshd.log since they don't even start. No I don't run any firewall 
besides xp
built in firewall and Symantec corporate antivirus. As I said there is no 
problem at all

with 1.5.18 and I never had any problems before. This is very frustrating.
Were the changes to fhandler_console really necessary?
Any other suggestions? Igor, Larry, Chris?
TIA, Yadin.

An strace doesn't help since the most part of the real action happens

FYI, I've applied a patch today which has two purposes:

- For directories, which are used as mount points, the d_ino was the one
  returned by Windows for this very directory entry.  However, for mount
  points, the inode number which should be returned (and which *is*
  returned by stat) is the inode number of the target directory/ target
  drive, the mount point points to.  This is (hopefully correctly)
  accomplished by the patch.

- As a fallout of this patch, mount points are now *always* listed with
  readdir, even if they are dangling with no underlying file or
  directory of the same name.  For eveyone who didn't understand this
  sentence, consider the both default mount points in /usr:

C:\cygwin\bin on /usr/bin type system (binmode)
C:\cygwin\lib on /usr/lib type system (binmode)

  Without my patch, an `ls' on /usr didn't return the directories bin
  and lib, except you created files or directories of this name in the
  C:\cygwin\usr directory.

  Now, with the patch, they are listed even though they don't exists in
  reality on the drive.  The additional advantage is that the shell's
  file completion now also works for these paths.

Please test the next snapshot from http://cygwin.com/snapshots/ for
this functionality.


Thanks,
Corinna

The good news is that the hang issues (signal related) that I was seeing

The bad news is that I'm now seeing a segmentation violation (4 or 5

figuring out how the crash occurred, because the last address in the

this be due to stack corruption, or does this look normal?). Anyway,

  Well, if I can /find/ a way to make it happen which doesn't involve building
a massive project using a hugely expensive proprietary vhdl compiler and
simulator, I'll let you know, but at the moment, any potential testcase should
be considered 'unreduced' and not exactly simple :)

  See http://cygwin.com/acronyms#PCYMTNQREAIYR for why!


  As to the source code for gcc, you can get it from whereever you got those
linux binaries from.  That's the beauty of the GPL!

  Alternatively you could download the source from one of the mirrors listed
at http://gcc.gnu.org/.  But it's possible the version you were using on your
linux machine has some arm-wince-specific patches added to it, so you'd be
better off with the source from your original compiler if you can find it.

  Building cross-compilers can be complicated, and it's way off-topic for the
cygwin list.  You probably want to use the crossgcc list if you have any
trouble building it.

Now, what would be really cool is if the link count of directories with
mount points could be updated, to match the fact that readdir can now see
mount points:

$ cd /usr/
$ ls -dl .
drwxr-xr-x+ 21 eblake Domain Users 0 Mar  1 09:22 ./
$ mkdir /cygdrive/c/cygwin/usr/lib
$ ls -dl .
drwxr-xr-x+ 22 eblake Domain Users 0 Mar  1 09:26 ./

Oops - see how the link count changed from 21 to 22 when I had a physical
backing directory?  find (and any other tool that optimizes a recursive
search to look at (link count - 2) subdirectories and then quit) might
get confused by the fact that the number of subdirs given by readdir is
no longer consistent with the link count.

Not surprising, as "groups" essentially calls "id -Gn".

This may be true (i.e., groups aren't listed properly)...  If you want to
strip down sshd code to just the piece that queries for the groups, run
that on Linux and Cygwin and demonstrate inconsistent results, I'm sure
Corinna would be interested in such a testcase.

As an example, with findutils-4.3.0-1 and cygwin built today (oldfind in
the 4.3.0 package uses the algorithm of the find utility in 4.2.27; the
find in 4.3.0 changed algorithms to fts() which avoids the subdir
optimization):

$ cd /usr
$ oldfind . -maxdepth 2 -mindepth 1 -name 'lib*' | wc
 70  701435
$ oldfind . -noleaf -maxdepth 2 -mindepth 1 -name 'lib*' | wc
755 755   16168
$ mkdir /cygdrive/c/cygwin/usr/lib
$ oldfind . -maxdepth 2 -mindepth 1 -name 'lib*' | wc
755 755   16168

Notice that without a physical /usr/lib under the mount point, oldfind did
not traverse into /usr/lib unless I used -noleaf to disable the link
count optimization, because /usr/lib appeared too late in the readdir.

The obvious thing to try would be to actually inspect the source code
up the stack around where the error occurred.  You'll have to make a
debugging version of ksh for that.

You can also set CYGWIN=error_start:/path/to/gdb.exe to have cygwin pop
up an instance of gdb whenever the program is about to die.

Just a point of interest here (maybe). I'm also seeing segfaults, but 
I'm running ksh (see thread: "shells hang during script execution"). 
Anyway, I just noticed that the last stack address (which looks bogus), 
as well as the EBP register value, are the same in the stack traces that 
both Peter and I posted:


Stack trace:
Frame Function  Args
0022E848  0022FBFC  (00484660, , 0009C05C, 0041E1F2)

Leading up to this are all pdksh functions:

40ab39 expand (after call to waitlast)
40a0fa evalstr
40cfa8 comexec
[...]

(in Peter's stack trace, these were all bash functions)

It would seem very coincidental for these two crashes not to be related 
somehow.


Peter, any chance you could maybe list the function names (in bash) that 
lead up the stack to this? Perhaps there's some common function that is 
causing this?

OK, I believe I've tracked this down.

The problem occurs when we get into a read_pipe cygthread constructor 
(cygthread::cygthread()) with a NULL h and an ev that is signalled.  When this 
condition exists, a hang can occur as follows:

1) Creator thread calls detach().  This waits for pipe_state to be released 
twice
2) read_pipe thread calls read_pipe, reads data, and releases the semaphore 
twice
3) Creator thread goes to WFSO(*this, INFINITE) which returns immediately 
because ev was set when the thread was created.
4) Creator thread initiates another read_pipe cygthread to read more pipe data.

At this point, there's a race: if the Creator thread gets past the 
initialization part of the constuctor, which sets __name(name), BEFORE the 
original read_pipe thread gets to the part of cygthread::stub() that sets 
info->__name = NULL, then you'll see the hang.  The new pipe_read will give the 
"erroneous thread activation" message, and the parent will be stuck waiting for 
data that will never arrive.

The only path that leaves an unused thread structure in a state where h==NULL 
and ev is signalled is cygthread::release().  So the fix is simple:

Nice analysis.  Thank you.  I think it's easier to fix this by just
making the ev event auto-reset then this condition would be caught in
terminate thread, as it was meant to be.

No effect of SE_BACKUP_NAME privilege on cygwin?

[Christian Franke]

Enabling SE_BACKUP_NAME has no effect for cygwin programs.

The attached program demonstrates the issue.
It retrieves the attributes of a normally inaccessible file without and 
with SE_BACKUP_NAME.

(The file should be present on XP with C:\ as system drive)

If compiled with "-mno-cygwin" and running as admin on XP Prof, the 
second access succeeds as expected:


GetFileAttributes failed: 5
SeBackupPrivilege enabled!
GetFileAttributes = 0x0026

But if running as a cygwin program on 1.5.19, the result is:

GetFileAttributes failed: 5
SeBackupPrivilege enabled!
GetFileAttributes failed: 5

The privilege can be enabled, but has no effect - bug or feature ?-)

Thanks for any help.

Re: 1.5.19-4 and gnu make 3.80-1 causes popup console windows from child make processes

[Paul]

I upgraded to 1.5.19-4 yesterday and now notice the following new,
undesirable behavior: empty console windows for child make processes.

I use the FTE editor and run make from it, the make output being
displayed inside an FTE window.  Before upgrading to 1.5.19-4, no
console windows popped up, even when make called child $(MAKE) (which
in turn call child $(MAKE) and so forth).

Now, I get a pop-up console window for make and each child make.  The
output from all of these still goes to FTE, but the empty popup console
windows take focus and are annoying.  This doesn't occur with other
external programs launched by FTE, just make.


I fixed the issue by modifying FTE. When I wrote earlier that I'd tried 
passing CREATE_NO_WINDOW to the CreateProcess that runs the make, I was 
wrong. FTE had a huge #if section, and I ended up changing the inactive 
one. When I added CREATE_NO_WINDOW to the real CreateProcess, make 
stopped popping up console windows.
(I still don't know why only make seems to do it and why it didn't until 
I upgraded cygwin. But I think the CreateProcess *should* need to have 
teh CREATE_NO_WINDOW parameter, and the problem is gone; so, I'm happy!)


I'm also happy I joined the list in time to see the post about 
CYGWIN=error_start! I've been cussing about cygwin's lack of useful core 
 file for ages (i.e., I can't do gdb core and then bt to see a stack 
trace with symbols and parameters). Using error_start should help!

Well, you could contribute the "useradd" and "groupadd" scripts that
invoke "net user" and "net group" respectively, and then run "mkpasswd -u
username >> /etc/passwd" and "mkgroup -g groupname >> /etc/group"...  I'm
sure this kind of functionality would be well received.

However, adding the user via the regular Windows means would still require
explicit synchronization.

Re: No effect of SE_BACKUP_NAME privilege on cygwin?

You're expecting that you can use Windows functions in a POSIX
application without disturbing the way Cygwin works.  That's a bit
dangerous.  A Cygwin application's main thread is not running under the
process token, but under a derived impersonation token.  This is true
for every thread in Cygwin.  So, instead of using OpenProcessToken, you
should be able to accomplish what you want by calling OpenThreadToken.

However, I'm wondering if a Cygwin application should always try by
itself to request the SE_BACKUP_NAME privilege.  It would simplify file
access for all privileged processes.  Hmm.

Problems with snapshot 20060227 ?

[Angelo Graziosi]

Usually I build ROOT (a Cern application) under Cygwin and this was done
also a few  day ago (with cygwin 1.5.19-4 and with the snapshots before
20060227).

Now with the snapshot 20060227 the build fails with:

  undefined reference to '___isnand'

I have noted that with this snapshot, math.h declares extern '__isnand'.

If it is extern, where is it defined?


Are these things related to the post:

  

and its replies?


Reinstalling cygwin 1.5.19-4 or the snap 20060224 the build of ROOT is
fine.


Cheers,

Angelo

Agree.

(I tried to add a "regtool save ..." action to allow backup of registry 
hives from scripts.

This calls RegSaveKey which needs SE_BACKUP_NAME.)

Yes, it works, thanks!

Already tried this before but gave up too early, because it didn't work 
in the non-cygwin version ;-)

I didn't realize that the main thread has no token by default...



However, I'm wondering if a Cygwin application should always try by

Sounds reasonable.
SE_RESTORE_NAME is requested somewhere in the code, but not SE_BACKUP_NAME.

rxvt and line-drawing characters

[Andrew DeFaria]

I like using rxvt as my terminal. Recently I discovered pstree (don't 
know how I missed it before). pstree doesn't appear to be in Cygwin but 
it does appear to be on Linux. I often use rxvt in conjunction with ssh 
to log into Linux machines. Now pstree supports a -G to use line drawing 
characters. This works under xterm but not under rxvt. How does one use 
line-drawing characters in rxvt?

You need a font that has the DOS/OEM characters instead of the standard
codepage 1252 / ISO 8858-1 character set.  If you search around there is
a patched version of lucida console (called "lucida consoleP" or
luconP.zip) that has this.  You also need to set TERM (-tn) to
rxvt-cygwin-native I think.

I've checked in a patch which should accomplish that.  Note that /proc
and /cygdrive always have a link count of 1 now, as for remote
directories.  In case of /proc, the real link count would only
coincidentally match the number of subdirectories, while in case of
/cygdrive the evaluation of the link count would result in accessing the
floppy drive for each stat.  Since the link count of 1 is known to work
even with older find versions, that seems the best compromise to me.
Other than that, the link count should be correct now for local
directories.

This has been discussed on this list yesterday.

Yes, that's a bit irritating.

I've applied a patch.
