Windows ARM64 - Cefclient Build Target

[leeroy]

I have been tasked with exploring the possibility of adding Windows ARM64 support to our application, which is largely based on the cefclient example. When attempting to build CEF without including the cefsimple build-target, the process fails with the following error message:

A client distribution cannot be generated if --build-target excludes cefsimple.

This raises two questions:
1. Is there something fundamental about applications based on cefclient that makes them incompatible with ARM64 architecture?
2. We prefer to include cefclient in our build process as a baseline test to ensure there are no issues with the vanilla cefclient in our setup and have a bases for comparison if we observe any odd bugs.

Thanks!

The cefclient app uses some APIs that are unavailable on Windows ARM64. You can try building cefclient on ARM64 using a binary distribution to see what fails currently.

Thank you, @magreenblatt. I manually compiled the vanilla cefclient for ARM64, and at first glance, it appears to run smoothly (at least on a colleagues arm64 windows laptop). Could you provide more details or docs on which APIs are currently unavailable if it's not too onerous?

Check if is running native and not emulated.

The application is running natively on a Snapdragon Windows 11 laptop. In the Task Manager's Details tab, both cefsimple and cefclient processes are listed with the architecture as ARM64. As expected, these binaries fail to run on x64 Windows, producing an error, which is consistent with my expectations. However, I’m uncertain about potential concerns or limitations when building an app based on cefclient. I’d prefer not to confirm support without a clearer understanding of any constraints.
