Design of setup.exe can make uninstallation of circularly dependent packages impossible
I'm not sure if this is the right mailing list for this, but I'll give it a shot anyway. I've been trying to uninstall the X11 packages for Cygwin, but a circular dependency combined with the nature of setup.exe seems to make this impossible. xorg-x11-bin requires libXft and libXft requires xorg-x11-bin. So, if both are installed, they become very difficult to remove: First you select one for uninstallation, then when you go to select the other for uninstallation you must toggle from Keep to Reinstall first, which reselects the first one for installation. The only possible way to select two things at once is if both are in the same category, but in this case, they aren't, so it appears there really is no way out. The same circular dependency problem exists with xorg-x11-bin and libXft1. It seems this problem could easily be fixed if setup.exe toggled from Keep to Uninstall before toggling to Reinstall, instead of the current scheme. Then one could select packages for uninstallation without accidentally activating dependencies, and circularly dependent packages in different categories could thus be uninstalled. Like I said, I'm not sure if this is the right mailing list on which to point out this problem. But for the time being, I just wanted to bring this to some attention (and also ask if there is any other way to uninstall X11). -Sridhar Ramesh -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
Circular dependency between xorg-x11-bin and libxft makes uninstallation impossible
I'm not sure if this is the right mailing list for this, but it's about Cygwin X11 packages, so I think I'm in the right place.

Like I said, I'm not sure if this is the right mailing list on which to point out this problem, and if the circular dependency can't be changed, perhaps what really needs changing is the toggling order in Setup.exe between Keep, Reinstall, Uninstall, etc. But for the time being, I just wanted to bring this to some attention (and also ask if there is any other way to uninstall X11). -Sridhar Ramesh
Re: Circular dependency between xorg-x11-bin and libxft makes uninstallation impossible
Unfortunately, at the start of a second run of setup.exe, setup will notice the missing package and reselect it for installation, it being a dependency of the non-missing package. Therefore, the second run of setup.exe starts off the same way the first run of setup.exe does, and so the second run of setup.exe can leave one no better off than the first one can. -Sridhar Ramesh Hello Sridhar, Am Dienstag, 10.

Run setup.exe twice? Gerrit -- =^..^=
