Comment 1 GouriKumari 2015-04-08 17:51:22 UTC
After discussing with Jose, it seems device builds fail consistently with the libc DllNotFound error, with all configurations.
I couldn't build a watchkit app or a singleview with AppStore|config as well. I am updating this bug with the build logs from building a watchkit app and a universal single view app.

Comment 2 GouriKumari 2015-04-08 19:00:21 UTC
I verified with a new mac build host,
and the build error seems to be resolved.

Test Results:
I could build a single view app successfully for device config and also could
deploy on device.

Build Log: https://gist.github.com/GouriKumari/9eaf262cfaf7c68a9c7e

With WatchKitApp : I could build the app successfully for Debug|iPhone config.

Build fails for WatchKitApp in CreateIPA step for AppStore|Config. 

Build Log for Debug|iPhone:
Build Log for AppStore|Config:

Supplemental Info:
This issue is fixed since the build error with libc DLL not found error is
resolved. However, WatchKit Projects do not build successfully for AppStore
config. I will open a bug for this for tracking purpose.

Test Env:
VS 3.11.385
Version: (Business Edition)
Hash: 4d68c9a +  mac build host
Comment 3 Saurabh 2015-04-09 01:42:27 UTC
I have checked this Issue with latest C5 builds and I am still getting build error when build the main project either of Template or WatchKitCatalog on iPhone|Debug. This is the build output for the same: https://gist.github.com/saurabh360/7ee540e633031b70eee5

X.iOS on Build host
Comment 4 Jose Gallardo 2015-04-09 08:29:21 UTC
The BuildHost including the fix is
That said, the Xamarin.iOS cycle 5 build which is going to bundle that BuildHost hasn't build yet.
The bundling update was done on commit https://github.com/xamarin/maccore/commit/f2da1d2b4bfbe29ec515157f0acbf43653a8811c

That being said, you can verify the fix manually installing that BuildHost ( on top of X.iOS, as that's the only difference between and the queued build (https://wrench.internalx.com/Wrench/ViewLane.aspx?lane_id=1503&host_id=163&revision_id=435928).

I can confirm is already on dropbox (https://www.dropbox.com/sh/n3cnpj3m1iup2qd/AAAcHoNaXpouTmPN6Dn_SxH8a/Cycle%205/XVS3.11/xamarin-ios-build-host-

Comment 6 Jose Gallardo 2015-04-09 11:45:01 UTC
We're waiting for a new X.iOS C5 build (the revision including the bump failed on the Upload to storage step). Rolf fixed the script and we should be getting a new build with the fix soon.
Comment 7 Mohit Kheterpal 2015-04-10 06:32:38 UTC
I have checked this issue using cycle 5 builds i.e. XVS 3.11.409 + X.iOS and observed that this issue is working fine now i.e.  we are able to build  watchkitcatalog sample. 

Hence closing this issue.
Comment 8 Mohit Kheterpal 2015-04-10 06:33:45 UTC
An update to the comment 7, I have checked it with Device and simulator.
