I started seeing this error with more recent builds of Windows, so I went to the Cygwin site and ran the latest installer to get the most recent binaries. I've had to do this periodically in the past 15 years, and fresh binaries have resolved my issues in the past. This time, the error persisted. A quick search seems to point to different versions of GCC used to compile Cygwin might have compatibility issues with different versions of Windows. I'd like to help get this resolved if I can.
Thanks, Sam Error: g:\os2\src\onecore\base\devices\association>ls Cygwin WARNING: Couldn't compute FAST_CWD pointer. This typically occurs if you're using an older Cygwin version on a newer Windows. Please update to the latest available Cygwin version from https://cygwin.com/.

It seems like this issue popped up like a week or two ago, so it probably started 5-10 build numbers ago. 0:000> vertarget Windows 10 Version 25888 MP (28 procs) Free x64 Product: WinNt, suite: SingleUserTS Edition build lab: 25888.1000.amd64fre.rs_dplat.230614-1400 Build layer: DesktopEditions -> 25888.1000.amd64fre.rs_dplat.230614-1400 Build layer: OnecoreUAP -> 25888.1000.amd64fre.rs_dplat.230614-1400 Build layer: ShellCommon -> 25888.1000.amd64fre.rs_dplat.230614-1400 Build layer: OSClient -> 25888.1000.amd64fre.rs_dplat.230614-1400 Debug session time: Fri Jun 16 12:02:33.676 2023 (UTC - 7:00) System Uptime: 0 days 8:43:16.926 Process Uptime: 0 days 0:13:15.247 Kernel time: 0 days 0:00:00.015 User time: 0 days 0:00:00.000 This is after I got the most recent version of Cygwin from the installer, it looks like version 3.4.6 built on Feb 14 2023. 0:000> lmDvmcygwin1 Browse full module list start end module name 00007ff9`03810000 00007ff9`03b12000 cygwin1 (deferred) Image path: g:\bin\cygwin1.dll Image name: cygwin1.dll Browse all global symbols functions data Timestamp: Tue Feb 14 05:25:13 2023 (63EB8BB9) CheckSum: 002D984A ImageSize: 00302000 File version: 3003.3.0.0 Product version: 3003.3.0.0 File flags: 0 (Mask 3F) File OS: 4 Unknown Win32 File type: 2.0 Dll File date: 00000000.00000000 Translations: 0409.04b0 Information from resource tables: CompanyName: Red Hat ProductName: Cygwin InternalName: cygwin1.dll OriginalFilename: cygwin1.dll ProductVersion: 3.4.6 FileVersion: 3.4.6 FileDescription: Cygwin POSIX Emulation DLL LegalCopyright: Copyright (c) Cygwin Authors 1996-2023 -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
