build issue typemaps.x86_64.ll: error: Could not open input file: no such file or directory

[hansmbakker]

Android application type

.NET Android (net7.0-android, net8.0-android, etc.)

Affected platform version

VS 2022 17.10 Preview 7

Description

When trying to debug my app, I sometimes get an issue like typemaps.x86_64.ll: error: Could not open input file: no such file or directory.
Another error I got was typemaps.armeabi-v7a.ll: error: Could not open input file: no such file or directory

This happens both in Visual Studio and on the command line using MSBuild.

The build error code is XA3006.

Steps to Reproduce

Not sure, but it is related to debugging on different devices having different processor architectures.

It happens e.g. when I try to deploy to my x86_64 emulator on my development machine after debugging via USB on a physical phone (which has an ARM processor).

Did you find any workaround?

No

@grendello let's discuss the build issue here.

I recorded a binlog and can share it confidentially (it contains client information).

@hansmbakker can you modify the C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\34.0.95\tools\Xamarin.Android.Common.targets file and apply the following diff:

And see if that fixes the issue?

I'm off until Monday and will reply when I have a chance to do it

@grendello I tried your change and it seems to help. I had to restart Visual Studio before it picked it up.

I updated the reproduction steps - it had something to do with switching debugging between devices that have different architectures.

Please note that xamarin/Xamarin.Forms#15719 and dotnet/maui#14531 (comment) seem to be related.

Just popping in to say I'm getting this error too, but don't think I have anything helpful to add. Let me know if there is something I could provide to assist though.
