Please answer. -----Urspr�ngliche Nachricht----- Von: Christopher Faylor [mailto:cgf AT redhat DOT com] Gesendet: Tuesday, June 25, 2002 6:07 PM An: cygwin AT cygwin DOT com Cc: cygwin-xfree AT cygwin DOT com Betreff: Troubles with 1.3.11? Try a snapshot. A couple of problems have been fixed in the recent cygwin snapshots, so please try one out and report success/failure to cygwin at cygwin dot com. I'll try to get a 1.3.12 out ASAP but I want to make sure that it fixes as many problems as possible first. Snapshot installation instructions: To install a snapshot: 1) Download the latest cygwin-20020???.dll.bz2 file from the above web page into a temporary directory. 2) bunzip2 cygwin-20020???.dll.bz2 3) Stop any running cygwin applications (sshd, inetd, bash, apache, etc.). 3) copy c:\cygwin\bin\cygwin1.dll c:\cygwin\bin\cygwin1.dll.saf 4) copy cygwin-2002????.dll c:\cygwin\bin\cygwin1.dll Obviously, you have to replace the 'c:\cygwin\bin' with the ms-dos path name of your /bin directory. You also *must* use Windows tools (e.g., "copy" or GUI "drag and drop") to copy the DLL to its new home since you can't easily overwrite a busy DLL. cgf -- Please do not send me personal email with cygwin questions.
