qt5-qtdeclarative and qt5-qtquickcontrols conflict

[dershow]

qt5 just upgraded from 5.6.2_1 to 5.7.1_0, along with subports. It seems that one of the subports is causing a problem:

It is not clear if force activation will break other subports, so I'm not sure how to proceed? Or should some other port be uninstalled before doing the upgrade?

Trac is not for tech support. Follow-up on the ​Macports Users mailing list instead.

If a user installs a port. Then, upgrades the port, and it fails, it is likely due to a bug in the port file. So, I would think that should be reported as such.

[mf2k (Frank Schima)]

You are right. This is a port conflict.

[mf2k (Frank Schima)]

What is weird is that they both installed without error for me when installing qt5 just now.

$ port installed qt5-qtdeclarative qt5-qtquickcontrols
The following ports are currently installed:
  qt5-qtdeclarative @5.7.1_0 (active)
  qt5-qtquickcontrols @5.7.1_0 (active)

Why do you see the conflict?

[jjstickel (Jonathan Stickel)]

I just encountered the same problem. Apparently libqquicklayoutsplugin.dylib moved from package qt5-qtquickcontrols to qt5-qtdeclarative in version 5.7.1. Updating causes a problem because qt5-qtdeclarative is earlier in the dependency tree and wants to install before qt5-qtquickcontrols, but the already installed qt5-qtquickcontrols-5.6.2 still owns the file.

Workaround is to force uninstall qt5-qtquickcontrols, then reinstall it (at the updated version). qt5-qtdeclarative will get updated in the process. I have no idea how to resolve the issue in the Portfiles to allow for a seamless update.

[neverpanic (Clemens Lang)]

This is a classic case for the "deactivate hack", see wiki:PortfileRecipes#deactivatehack. qt5-qtdeclarative needs to force-deactivate the old version of qt5-qtquickcontrols.

[neverpanic (Clemens Lang)]

The same probably applies for qt5-qtenginio and the qt5 port; instead of telling the user to manually uninstall qt5-qtenginio, the qt5 port should just force-deactivate it.
