I tried searching with 'Search Hiden Files & Folders' checked.  It still

Then try "Process Explorer".  Grab it from sysinternals.com.  With that,
you can find out what process is running cygwin1.dll and where it is.

Great tool!!  Thanks.  Tried it.  I ran rxvt from the new cygwin
installation and that's what's showing up (and sh) as using the
cygwin1.dll.  The one from c:\cygwin\bin is being used by these apps.
If I exit rxvt, then there's no other process using the cygwin1.dll.

Looks like there is no other version of cygwin1.dll running.  Do I have
something really corrupted.

I was actually wondering how can I run rxvt and some other tools, while
I cannot run X, etc..  Do they use shared memory differently? Or not
make the version checks?

If you can run rxvt but not X that would suggest that you are running
some other version of X than the standard cygwin version which has its
own cygwin1.dll.  Do you have other web downloaded packages installed?

Possibly the cygcheck output mentioned at http://cygwin.com/problems.html
would be more instructive.

Thanks.  That helped.  I ran cygcheck and looked at the output.  Yes,
there is another cygwin1.dll in system32 folder.  It doesn't show up if
I use Windows Search (even with "search hidden files and folders" option
checked).  Even if I go to system32 folder and enable showing of hidden
files, it doesn't show up.  In cmd.exe, if I do 'dir' it shows up.  But,
if I delete it from cmd.exe, it says file not there.  But, I was able to
delete it from rxvt using rm.

I see another similar (hidden) file called cygz.dll in sys32 folder.
Shall I delete this too?

The only warning I saw in cygcheck output is for multiple cygwin1.dlls.
The X is not running for other reasons.  I'm going to uninstall and
re-install and see if I can run X.

Yes, and any other cyg*.dll you find in the system directory.  Most likely,
some <http://cygwin.com/acronyms/#3PP> installed stuff there just to make
your life misreable.

Make sure, if you're using Windows search, that you tell Windows to show
you hidden files and folders.  These options are in the "View" tab under
"Folder Options..." in the Explorer "Tools" menu.  Windows hides lots of
important stuff by default. :-(

system shared memory mismatch problem

[Akula, Murali]

Hi,

I installed/uninstalled cygwin couple of times, previously.  When I
install a new version (1.5.24) now, I get the following error, when I
start any app:

*************
C:\cygwin\usr\X11R6\bin\xinit.exe (2936): *** system shared memory
version mismatch detected - 0x2D1E009C/0x75BE0081.
This problem is probably due to using incompatible versions of the
cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version
*should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.
**************

I searched on my drive and the only cygwin1.dll is x:\cygwin\bin.  I
uninstalled cygwin (as recommended at the FAQ) cleaned registry entries
and path, etc.., rebooted and installed cygwin again.  I continue to see
the same problem.
Is there a way to find which app is creating the shared memory area? Any
help is appreciated.  How can I fix this without having to reimage my
machine?

Thanks.
Murali.
