I'm still seeing this problem. The sources we are building are proprietary (sorry), but I can reproduce this with both CITI's NFSv4.1 and Windows 10 builtin NFSv3 clients. Setup for Windows's NFSv3 client on Cygwin is simple: 1. Install Windows 10 builtin NFSv3 client via "Programs&Features" (I think there is a way to do that in a scripted way, but I still didn't had time to figure that out) 2. Export NFSv3 directory 10.49.20.131:/export/home/rmainz (rmainz has uid=1616, gid=1616) on a Linux NFS-Server (RHEL, Debian etc.) 3. Mount NFSv3 filesystem in Windows 10 in a Cygwin terminal, with default user uid=1616, gid=1616 like this: ---- snip ---- $ regtool -i -s set '/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/ClientForNFS/CurrentVersion/Default/AnonymousUID' 1616 $ regtool -i -s set '/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/ClientForNFS/CurrentVersion/Default/AnonymousGID' 1616 $ /cygdrive/c/Windows/system32/mount -o anon '\\10.49.20.131\export\home\rmainz' H: ---- snip ---- 4. After that I started building our sources with Cygwin 3.4.7 (works), then closed all Cygwin windows etc., and installed Cygwin 3.5.0-0.388.g1a646ad7970a.x86_64 (reboot or not reboot - doesn't matter). After that the build fails. - See https://rovema.kpaste.net/e5774d8077 build log on Cygwin 3.4.7, which works without problems - See https://rovema.kpaste.net/1a3b98e0b for the build failure on Cygwin 3.5.0-0.388.g1a646ad7970a.x86_64 - The horrifying abdomination ("buildrdecygwin.bash") used to build the mess can be found at https://rovema.kpaste.net/e98be ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.ma...@nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;) -- 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
