Unable to import iOS SDK Essentials with only core features selected

Question

I just added "iOS SDK Essentials" to my project. From the options, I unchecked all the preview modules. I also deleted all of the example scripts, since they were giving me errors. However, I still get four errors (two of each of the following):

FileNotFoundException: Could not load file or assembly 'U3DXTPersonal, Version=1.7.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. EntryPointNotFoundException: UP_CoreXT_init

Note that I did NOT select the Personal module.

I'm just using the sample code to pick an image, so the second exception is from this line:

     if (CoreXT.IsDevice)

How do get get rid of these errors?

It appears that the U3DXTPersonal.dll is always required. I renamed the U3DXTPersonal.dll_disabled to U3DXTPersonal.dll and the FileNotFoundException error went away. I guess there's a bug that forces this dependency even when you don't check that box (and I did press OK after de-selecting everything).

I'm still getting the error from the CoreXT.IsDevice call, though (EntryPointNotFoundException: UP_CoreXT_init). I'm running it from Unity. Is this error expected in this case? I haven't tried running it on a real device.

Unity does not support running native plugins from within the Editor or Simulator. So in order to use U3DXT, you need to run it on real devices.

Sorry, I mis-spoke. It was a compile error, not a run-time error. The error occurred when I was trying to generate an iOS build from Unity.

After enabling U3DXTPersonal.dll, I now get:

 Win32Exception: ApplicationName='python', CommandLine='Assets/U3DXT/Editor/post_process.pyc "I:/OSX/ecbuild" "D:/unity/EigenCA$$anonymous$$/Assets/U3DXT/Editor/lib" "CoreGraphics~|~QuartzCore"', CurrentDirectory=''

 System.Diagnostics.Process.Start_common (System.Diagnostics.ProcessStartInfo startInfo, System.Diagnostics.Process process)
 System.Diagnostics.Process.Start ()

I installed Python, but it still gives me that error. Here's what I get if I run it manually:

 D:\unity\EigenCA$$anonymous$$>Assets\u3dxt\editor\post_process.pyc "I:/OSX/ecbuild" "D:/unity/EigenCA$$anonymous$$/Assets/U3DXT/Editor/lib" "CoreGraphics~|~QuartzCore"

O$$anonymous$$, I see the problem. U3DXT does not support building on Windows now. We are looking into adding support. In the meantime, you will need to build and run from $$anonymous$$ac.
