The CI runs for *every* commit, with hundreds of commits a day. My... crime... was to update Cygwin to Cygwin 3.6.1. After that, Cygwin no longer works on WIndows network shares. > >>> Now on Windows 10 with Cygwin 3.6.1 it fails with error 127. > >> That can mean a missing DLL function entry. > > > No, I do not think so, as Cygwin works fine if I install it on NTFS. > > So you are not installing it on NTFS? > What kind of share are you installing it on? Windows 10 Enterprise (NT-10.0-19045), we use net use N: ... to mount the standard Windows network share.

I need to anonymise that, or IT will want my reprimation. But the steps I posted fail on ANY Windows 10 and Windows 11 machine I have tested so far, Windows Home, Enterprise and Pro. All you need are the steps I posted, the KEY being doing an installation on Windows Server Message Block filesystem. That is all.
