After years of ignorance I discovered the wonderful GNU screen program on my GNU/Linux system. Basically screen is a window manager for terminals or terminal sessions. But after installing the Cygwin package on my Windows box I ended up with this error message after trying to invoke screen:
This is unlikely to help others, but I’ll keep it as a reference… The culprit was a messed up installation. I had the following directories:
1 2 3 4
I just had to delete the empty directories and rename tabset(2) and terminfo(2)
1 2 3
and now screen works just fine with Cygwin.
