Re: Cygwin "linked dll data write copy failed" on Windows 7 virtualized

[Tine Lesjak]

Thank you, Andy. To run rebaseall for each image load is a great idea. 
Now, I'm trying with this and so far so good. But I don't have much time 
to spend on testing and this problem occurs very randomly. I'll tell 
you, when I find out for sure if this is the case.

Windows 7 is freshly installed with Windows Defender disabled. I'm aware 
of "BLODA" (http://cygwin.com/faq/faq.using.html#faq.using.bloda).

Thank you again.

If you haven't already done so, try using the current

Changes have been made to this file since VCL 2.1 including the 
addition of calling rebaseall.  I know you said you tried rebaseall, 
but you'll definitely want to have the updated script saved in your 
Win7/2008 images because unpredictable behavior occurs if rebaseall 
isn't run for each image load.

Do you have any other software installed in the image such as an 
antivirus client?  If so, I'd try uninstalling it.  You could also try 
disabling any non-essential services to see if any of them are the 
culprit.

Hi all,



We are experiencing big troubles with Cygwin 1.5 (legacy) on Windows 
7. We
tried various "versions" of Windows 7 (32/64 bit, different locales,
different settings for Cygwin SSHD (delayed startup, rebaseall, 
special DEP
settings, Windows Firewall as dependency service), Windows Defender 
is off).
The problem is always when VCL tries to set Windows Firewall. For 
example:



Example 1:

Command:

reg.exe ADD 
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal
Server" /t REG_DWORD /v fDenyTSConnections /d 0 /f ;

reg.exe ADD 
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal
Server\WinStations\RDP-Tcp" /t REG_DWORD /v UserAuthentication /d 0 /f ;

netsh.exe advfirewall firewall delete rule name=all dir=in protocol=TCP
localport=3389 ;

netsh.exe advfirewall firewall add rule name="VCL: allow RDP port 
3389 to:
10.7.97.227" description="Allows incoming RDP (TCP port 3389) traffic 
to:
10.7.97.227" protocol=TCP localport=3389 action=allow enable=yes dir=in
localip=10.7.97.227

Example 2:

name="VCL:TempAllowAllToPrivate" description="Allows all traffic to

Ok.

It is strange, since Windows Server 2008 seems to work (but we haven't
tested it so heavily). We are using quite modified VCL 2.1, hosts are 
VMware
ESXi 4. I'm pretty sure, that the problem is not with VCL (because we
modified it), but solely with Cygwin/Windows 7.



I'm just asking if someone has already bumped to this problem.

Thank you!
