Can't build .NET 7 android projects

Android application type

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

Affected platform version

VS 2022 17.5.3, .NET SDK 7.0.200, osx.13-arm64, Mono 6.12.0.188

@grendello

@grendello any ideas on this one?

@mrhenkiz

This code is generated when assembly stores are disabled ($(AndroidUseAssemblyStore)=False), but I've just tested it locally and it builds fine with XA/main. @mrhenkiz can you please attach the whole project directory after build (that is with bin, obj, sources etc)?

Fragment of code generated locally when assembly stores are disabled:

; Bundled assembly name buffers, all 70 bytes long
@bundled_assemblies = local_unnamed_addr global [154 x %struct.XamarinAndroidBundledAssembly] [
        ; 0
        %struct.XamarinAndroidBundledAssembly {
                i32 -1, ; apk_fd
                i32 0, ; data_offset
                i32 0, ; data_size
                i8* null, ; data
                i32 70, ; name_length
                i8* getelementptr inbounds ([70 x i8], [70 x i8]* @__XamarinAndroidBundledAssembly_name_0, i32 0, i32 0); name
        },

It's an array of such entries, the fragment in the error message in OP isn't sufficient to say what llc doesn't like.

@grendello

@grendello Thanks for the quick response. The zipfile is 26mb and I'm only allowed to upload 25mb. Is there any folders that i can skip to make the file smaller ?

EDIT: Uploaded it to file.io

I can confirm that the ll files in the provided sample fail to build, even though the code between my local test and them is nearly identical (the only difference is buffer size):

Local:

; Bundled assembly name buffers, all 70 bytes long
@bundled_assemblies = local_unnamed_addr global [154 x %struct.XamarinAndroidBundledAssembly] [
        ; 0
        %struct.XamarinAndroidBundledAssembly {
                i32 -1, ; apk_fd
                i32 0, ; data_offset
                i32 0, ; data_size
                i8* null, ; data
                i32 70, ; name_length
                i8* getelementptr inbounds ([70 x i8], [70 x i8]* @__XamarinAndroidBundledAssembly_name_0, i32 0, i32 0); name
        },

Example app:

; Bundled assembly name buffers, all 66 bytes long
@bundled_assemblies = local_unnamed_addr global [211 x %struct.XamarinAndroidBundledAssembly] [
        ; 0
        %struct.XamarinAndroidBundledAssembly {
                i32 −1, ; apk_fd
                i32 0, ; data_offset
                i32 0, ; data_size
                i8* null, ; data
                i32 66, ; name_length
                i8* getelementptr inbounds ([66 x i8], [66 x i8]* @__XamarinAndroidBundledAssembly_name_0, i32 0, i32 0); name
        },

Syntactically they're identical, so it must be something else in the file throwing llc off. Fascinating.

If I manually change -1 to 0 then it works. Baffling :)

@grendello

@grendello I don't know if it helps. But the errors for environment is randomly between every build. Sometimes it only complains about ie. environment.arm64-v8a.ll and other builds it complains about one or more. :)

@mrhenkiz

@mrhenkiz I suspect there's some earlier bit of code that is somehow corrupted (perhaps a filesystem issue, hard to tell). I'll investigate later today and will try to reproduce locally using your sample.

@grendello

@grendello Great, thanks. I can also say that i get same errors on a wiped intel mac where I only installed vs 2022 17.5.3 and created a project from the template (same versions as on the M1) and built.

@grendello

Thanks for quick response @grendello. @rhult Did you confirm that it's working if you change LANG ? Where to change the lang in macos?

If you build from command line, you can just do:

$ LANG=en_US.UTF-8 dotnet build [...]

@mrhenkiz

@mrhenkiz you can put

export LANG=en_US.UTF-8

in the .profile file in your home directory, then that value of LANG will be used for all terminal sessions. For GUI apps you'd either have to use the defaults utility (from terminal, do defaults read | less to see all the settings) or change the language in the macOS settings app.

@grendello

@grendello Thank you. It worked like a charm when I added it to .zshrc :) Great job!

I have same error after changing system language from zh-TW to en-US.

1>C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\33.0.26\tools\Xamarin.Android.Common.targets(1979,3): error XA3006: Could not compile native assembly file: typemaps.arm64-v8a.ll

@PRMrainbow

@PRMrainbow are you absolutely sure it's the same error? The zh-TW culture appears to use the ASCII hyphen as the minus character. Can you build your app from command line with:

dotnet build -c Release -bl
dotnet msbuild -v:diag msbuild.binlog > msbuild.txt

and then locate the string error XA3006: in msbuild.txt to see what the actual error is (it will be somewhere above the error line, might be mixed up with other lines if parallel build is in effect)

Well... It was built successfully with 'dotnet build -c Release -bl' while building in Visual Studio IDE it failed. So I can't get an error in msbuild.txt.

@PRMrainbow

@PRMrainbow then it's unlikely to be the same issue. However, maybe you'll get more info if you enable diagnostic MSBuild messages inside the IDE and hunt for the error in the output buffer after the build fails there.
