[12:44] <AdamH> Hello, I am trying to understand Qt, mir and snaps. I have written a Hello World app using Qt which works on a Desktop. But when I install the Snap on Ubuntu Core I get the following error Apr 12 10:50:58 localhost snap[1292]: cannot perform operation: mount --bind -o ro,nosuid,nodev /snap/mir-libs/28/mirlibs0/usr/lib /snap/falconhelloworld/x1/mir-libs: No such file or directory. Directory doesn't exist but not sure what I am missing
[12:44] <AdamH>  as I have used mir-kiosk-apps as a guide. Any pointers as to how I debug this?

[13:04] <alan_g> AdamH: sounds like you're missing the mir-libs content interface.
[13:04] <alan_g> I'm not very familiar with the snaps error messages, but have you tried the example clients?
[13:08] <AdamH> alan_g: I have the following interfaces mir-kiosk:mir             falconhelloworld and mir-libs:mir-libs         falconhelloworld,mir-kiosk
[13:09] <AdamH> I have used mir-kiosk-apps and it works correctly. So must have something set wrong in snapcraft I assume
[13:10] <alan_g> That would be my guess too. (But all the snapcraft I've done has been copy & change.)
[13:11] <alan_g> When you say the directory doesn't exist do you mean /snap/mir-libs/28/mirlibs0/usr/lib or /snap/falconhelloworld/x1/mir-libs
[13:11] <alan_g> ?
[13:12] <AdamH> It is /snap/falconhelloworld/x1/mir-libs that does not exist
[13:13] <alan_g> OK, you're just missing that directory in your snap.
[13:14] <AdamH> Yes just not sure how I pull it in at the moment
[13:16] <alan_g> Do you have the (empty) folder in github?
[13:17] <AdamH> No but I have noticed in the mir-kiosk-apps demo there is an emtpy folder in glue, is that all I need to do?
[13:20] <alan_g> You need the empty folder for bind to work.
[13:20] <AdamH> ha thanks... will give that a try now
[13:20] <alan_g> My example uses this yaml: https://bazaar.launchpad.net/~alan-griffiths/mircade-snap/trunk/view/head:/snap/snapcraft.yaml
[13:21] <alan_g> If that doesn't work, the folks on #snappy may know what the incantations mean.
[13:21] <AdamH> Thank you will give it a go
