Hello everyone!
I have two machines in my posession: a desktop and a laptop. Both
machines have Windows 10 and the same up to date version of Cygwin
installed. The only difference is "age". The laptop is a new one, with
freshly installed OS and Cygwin, and the desktop is about one year old
and its hard drive is about 10 years old, Cygwin was installed a while
ago and periodically upgraded.
So far, on the desktop PTY does not work. Attempt to run docker (i am
using Docker Desktop for Windows) causes "Terminal is not a PTY" error,
i have to use winpty wrapper as suggested. On the laptop everything is
fine, docker works in MinTTY out of the box with no need for winpty.
Is there maybe some hidden setting, which got stuck somewhere in the
older system ? Why is PTY not working? Can anyone help me to diagnose
that ?
If your desktop Windows version is a bit older, it may not yet support
the ConPTY API, so cygwin will silently drop its own conpty support. You
might compare the build numbers (cmd /c ver, or winver).
Hi pavel,
what is the setting of CYGWIN variable ?
I suggest you to run
"cygcheck -svr > cygcheck.out" and compare the output files
No idea what is "Docker Desktop" but I suggest you to verify that you
are really running mintty with the same invocation in the two cases.
