I did forget to mention that I had this working at some point back in the mid-August timeframe (for initial proof of concept), but after a combination of updating my host machine and using the latest Snappy/Mir versions it no longer worked. My environment is also different in that I'm building the Qt clock snap against the latest version of 15.04, which is what I would need to do for my own custom application that will eventually be installed on Snappy. For a test, I tried removing my custom mir snap and installed the mir.mvp-demo snap from the store. When I try to run my custom snaps (built against the latest 15.04 mir client libs) with the older server (mir.mvp-demo), I get the following error instead... $ sudo qtdeclarative5-examples-amd64.clocks Bad system call Loading module: 'libubuntu_application_api_desktop_mirclient.so.2.9.0' [1444693723.318984] Loader: Loading modules from: /apps/mir/snap1.1/debs/usr/lib/x86_64-linux-gnu/mir/client-platform [1444693723.320623] Loader: Loading module: /apps/mir/snap1.1/debs/usr/lib/x86_64-linux-gnu/mir/client-platform/mesa.so.2 [1444693723.326652] <WARNING> Loader: Failed to load module: /apps/mir/snap1.1/debs/usr/lib/x86_64-linux-gnu/mir/client-platform/mesa.so.2 (error was:libmircommon.so.4: cannot open shared object file: No such file or directory) UbuntuClientIntegration: connection to Mir server failed.
