@jonathanpeppers Thoughts?

[jonathanpeppers]

I think we need a repro or MSBuild diagnostic log.

@arvindrajachourasiya looking at the error message in the log:

1>        [LLVM llc] C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.46\tools\binutils\bin\llc.EXE -O2 --debugger-tune=lldb --debugify-level=location+variables --fatal-warnings --filetype=obj --relocation-model=pic -o=environment.arm64-v8a.o environment.arm64-v8a.ll

What are the contents of obj\Debug\net7.0-android33.0\android\environment.arm64-v8a.ll? @grendello any other information that would be useful here?

I don't see a custom @(AndroidEnvironment) file in the log.

[grendello]

@arvindrajachourasiya could you attach the environment.arm64-v8a.ll file please? You can find it in obj\Debug\net7.0-android33.0\android\environment.arm64-v8a.ll, thanks!

[grendello]

@jonathanpeppers once I have the file, I can run llc on it locally and see what's the error

[arvindrajachourasiya]

@jonathanpeppers @grendello - Please find the files below. I have attached 4 files there as I am getting 4 errors.
environment.arm64-v8a.zip

Below is the screenshots of errors.

When I keep building my project, every time I get different error (out of 4) and sometimes all 4 errors are coming. This time I am getting all the errors. Added screenshots and logs.

Log file for 4 errors

[grendello]

@arvindrajachourasiya @jonathanpeppers so it's both good and bad news. The files attached by @arvindrajachourasiya, thank you, compile just fine. That's the good news.

The bad news, there's no actual error in the provided log and I suspect the failure being environmental - something on the machine is causing the process to fail. Shortage of disk space, resource limits imposed by the OS, a filesystem corruption all come to mind but it's impossible to say what it is in the absence of actual errors :(

@arvindrajachourasiya I'm afraid I will need to ask you to build the app from command line, producing a binlog file, hoping it will have more info.

Please build the app as follows from VS developer command prompt (after first removing all the bin and obj directories in the project) until the build fails:

dotnet build -bl

Please attach the failed build's msbuild.binlog file here.
