[mono] Add iOS app builder project #34563

EgorBo · 2020-04-05T13:18:26Z

This PR adds a project with a single msbuild task. This task creates an *.app bundle for iOS (device or simulator) from a list of *.dll files with some simple UI (can be configured).

Usage:

  <UsingTask TaskName="AppleAppBuilderTask" 
             AssemblyFile="$(ArtifactsObjDir)mono\AppleAppBuilder\$(TargetArchitecture)\$(Configuration)\AppleAppBuilder.dll" />

  <Target Name="BuildAppleApp">
    <AppleAppBuilderTask 
        Arch="$(TargetArchitecture)"
        ProjectName="$(ProjectName)"
        Optimized="$(Optimized)"
        MonoInclude="$(BinDir)include\mono-2.0"
        CrossCompiler="$(BinDir)cross\mono-aot-cross"
        MainLibraryFileName="$(MainLibraryFileName)"
        NativeMainSource="$(NativeMainSource)"
        GenerateXcodeProject="$(GenerateXcodeProject)"
        BuildAppBundle="$(BuildAppBundle)"
        DevTeamProvisioning="$(DevTeamProvisioning)"
        AppDir="$(AppDir)">
        <Output TaskParameter="AppBundlePath" PropertyName="AppBundlePath" />
        <Output TaskParameter="XcodeProjectPath" PropertyName="XcodeProjectPath" />
    </AppleAppBuilderTask>
    <Message Importance="High" Text="Xcode: $(XcodeProjectPath)"/>
    <Message Importance="High" Text="App: $(AppBundlePath)"/>
  </Target>

For x64 (Simulator) DevTeamProvisioning and CrossCompiler are not required.

How it works

First of all it needs a AppDir directory (e.g. dotnet publish result) with:

Entry point library (e.g. Program.dll) it can be a hand-made xunit runner or a HelloWorld app
All managed dependencies including BCL libraries and System.Private.CoreLib.dll (mono's one)
All static files: libmono.a, libSystem.Native.a, etc.
Other files are bundled as resources (e.g. pdb, configs, etc)

AotCompiler runs FullAOT compilation and produces *.dll.o files with help of clang (it does it in parallel).
Also, it creates modules.m file where it lists all the linking symbols from all *.dll.o.
Then it creates a CMakeLists.txt in order to create an xcode project via cmake.
That xcode project produces app bundles via xcodebuild command.

These app bundles are ready-to-use e.g. to be deployed to simulators via xcrun simctl install/launch or to real devices via mlaunch or ios-deploy tools.

Notes:
FullAOT compilation is used only for arm64 builds
Some tests crash (e.g. all with remote executor)

I'll add a hand-made xunit runner app in a separate PR.

How to run the sample:

git clone git@github.com:dotnet/runtime.git
cd runtime/src/mono/netcore/iOS
make MONO_ARCH=arm64

Is this a task that you're going to ship? Or is it for internal consumption? What we need is a task that only does the AOT compilation (takes the managed assemblies as input, and produces .o/.m files as output).

EgorBo · 2020-04-06T11:34:59Z

What we need is a task that only does the AOT compilation

It'd make sense to sync with @akoeplinger as he has been working on same thing

@marek-safar @rolfbjarne It looks like there is a miscommunication, I was asked to make a task from my makefile scripts to produce app bundles from libraries (tests)

+                .ToArray();
+        }
+        string[] libsToAot = Directory.GetFiles(AppDir, "*.dll")


I still think this should come as input to the task (e.g. from publish)

the AppDir is basically the dotnet publish location - we need everything in the directory anyway.
Collection of files as an input makes it harder to use via command line 🙁

+        ProjectName="$(ProjectName)"

+        MonoInclude="$(BinDir)include\mono-2.0"


This should better come from runtime pack

cc @steveisok @akoeplinger
how do I build the "runtime pack", I've just built my repo with build.sh -c Release -os iOS -arch arm64 -subset Mono+Libs+Libs.Tests and don't see any runtime packs. The only location where I can find mono-2.0 headers and mono-aot-cross is this $(BinDir)

It's in a PR. You'll have to update src/mono/netcore/sample/iOS/Program.csproj when it's ready.

This should also come from the runtime pack.

LGTM once you address the comments

We should attach ErrorDataReceived and OutputDataReceived before we start the process or we could miss some output.

And maybe also follow the recommendations from #18789 (comment)

We should attach ErrorDataReceived and OutputDataReceived before we start the process or we could miss some output.

Looks like it won't miss anything, furthermore you can't start listening for outputs before you start the actual process - it throws StandardOut has not been redirected or the process hasn't started yet

#18789 (comment) doesn't apply here since I actually use the parameterless overload

steveisok · 2020-04-13T16:44:05Z

@marek-safar I think this is good to go. We'll likely need a follow up PR once the in-tree runtime pack functionality is there. Since we want to make available some kind of test runner, I think this PR shouldn't wait.
