Short version: Cygwin stopped working on my laptop for unknown reason, so I deleted it and attempted to reinstall. Re-installation of cygwin failed for unclear reasons. Please Help!
Long version: I've had cygwin on my company laptop (32 bit WinXP Pro SP3) for about 2-years and it just recently stopped working ... I fear some kind of policy update pushed out by company administrators broke something but I don't know how to figure out what exactly happened. The powers that be don't support cygwin on company machines, so I can't get any help from them. I ran setup.exe to re-install cygwin and that failed. I deleted the entire installation of cygwin then re-ran setup.exe to make a clean install ... still failed. Every package seems to have exited with same or similar error message, starting with this: "2013/04/30 16:03:45 running: C:\cygwin\bin\bash.exe --norc --noprofile "/etc/postinstall/000-cygwin-post-install.sh" 10 [main] mount (5944) C:\cygwin\bin\mount.exe: *** fatal error - cygheap base mismatch detected - 0x771940/0x6E1940. This problem is probably due to using incompatible versions of the cygwin DLL." I googled that message about base mismash and all the evidence points to cygwin1.dll being the issue but there's nothing useful about fixing it. The only instance of that dll on this machine is the one downloaded and installed by the setup.exe program, so it doesn't make sense to think it's a bad version. This was a fresh install so it appears to me that cygwin1.dll is not getting installed properly by the installation script ... it's apparently not getting loaded into Windows and since everything depends on that one dll, nothing works. There is no mention of that dll in the setup logs (full or standard) although I know it is part of the cygwin base package. The cygwin1.dll file is present in /bin ... but nothing seems to work. Rebooted after install and still no joy. Can anyone suggest some troubleshooting to help resolve this? I feel severely handicapped without cygwin working on my laptop :-( Thanks, John -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
