I am attempting to install the ArcGISMapsSDK v1.1.0 plugin in Unreal Engine 5.1 and I receive the following errors:

Any clues on how to fix it?

I don’t know if something changed these last month but AFAIK the SDK is still not compatible with 5.1

Best,

Hi Nick,

Unlike version 1.0.0, version 1.1.0 can run with Unreal Engine 5.1. So I'm wondering how you installed the plugin and how you are launching the project after installing it. Can you provide such info?

[nick_recursion]

I followed the instructions provided on https://developers.arcgis.com/unreal-engine/ to the best of my ability. I am using the clang compiler, maybe that is related to these issues?

Hi Nick,

Developing with Unreal Engine requires Visual Studio on Windows. 

You can find ArcGIS Maps SDK for Unreal Engine's system requirements at https://developers.arcgis.com/unreal-engine/reference/system-requirements/

And there is documentation from Unreal Engine about setting up Visual Studio at https://docs.unrealengine.com/5.1/en-US/setting-up-visual-studio-development-environment-for-cpluspl...

Hope it helps,

[nick_recursion]

Solved. 
The clang compiler is incompatible with the plugin currently and was preventing the build. 

In case it is still useful, 
Visual Studio returned the following build errors: 

1>Using Clang 14.0.5 compiler (C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\Llvm) with Visual Studio 2022 14.33.31630 runtime (C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.33.31629) and Windows 10.0.19041.0 SDK (C:\Program Files (x86)\Windows Kits\10).
