Could not AOT the assembly #8944

Open danim-hub opened 4 years ago

danim-hub commented 4 years ago

I am getting this error compiling a Xamarin.Forms on Visual studio for Mac, targeting Release|iPhone /Users/danim/apps/logistics/Sales.iOS/MTOUCH: Error MT3001: Could not AOT the assembly '/Users/danim/apps/logistics/Sales.iOS/obj/iPhone/Release/mtouch-cache/3-Build/Logistics.Sales.dll' (MT3001) (Logistics.Sales.iOS)

It started happening with no apparent reason. This particular branch haven't had any commit since Jun 3rd, so I cannot tell exactly when it stopped compiling.

In Android it works fine.

It only happens in Release|iPhone mode. On Debug|iPhone it compiles, installs and runs fine.

I found online several workarounds for similar issues from 1 to 3 years old, but with no luck:

Steps to Reproduce

  1. Build my solution with Debug|iPhone - Builds OK
  2. Build my solution with Release|iPhone - Error appears
  3. Build from jenkins/msbuild (it was working on couple of weeks ago) - Also fails

Expected Behavior

The compiler generates an ipa

Actual Behavior

I get this error: /Users/danim/apps/logistics/Sales.iOS/MTOUCH: Error MT3001: Could not AOT the assembly '/Users/danim/apps/logistics/Sales.iOS/obj/iPhone/Release/mtouch-cache/3-Build/Logistics.Sales.dll' (MT3001) (Logistics.Sales.iOS)

Example Project (If Possible)

Sorry no example minimum project yet. I am attaching the csproj for reference hope it helps

Logistics.Sales.iOS.csproj.txt

chamons commented 4 years ago

Would it be possible to attach Logistics.Sales.dll itself at least?

Without a sample, we can't dig into the AOT error.

danim-hub commented 4 years ago

I made a very simplified version of the project.

Please remove the .txt extension as the file is a tgz.

I think the offending line is in class InventoryReportTemplate:

            #line 6 ""

repro6.tgz.txt

chamons commented 4 years ago

I can reproduce the AOT issue with the provided sample.

It only happens first few times I build, after awhile it seems to fix itself even after a clean. Something strange is going on.

Redth commented 4 years ago

@jonathanpeppers this could be a bin/obj thing, could you have a look?

chamons commented 4 years ago

I think https://github.com/xamarin/xamarin-macios/issues/8957 might be a duplicate re-filed by the customer, or a related issue.

danim-hub commented 4 years ago

Hi Chris. That is another issue, although the scenario is very similar, it is not identical. When preparing the repro for this MT3001, I also got an MT5106 error, and the error message instructed to file an issue.

The repro is very similar but it has a couple of changes in a single file, and results in a different error code and message.

I hope this lets you catch two different bugs, but it is possible that both have the same cause

Thanks for your help

I don't think this is a bin/obj problem, because the first build fails for me (or even Rebuild):

 % msbuild Sales.sln /p:Configuration=Release /p:Platform=iPhone /r /t:Rebuild
...
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS13.5.sdk -Qunused-arguments -miphoneos-version-min=9.0 -arch arm64 -c -o /Users/jopepper/Downloads/logistics/Sales.iOS/obj/iPhone/Release/mtouch-cache/arm64/Xamarin.iOS.dll.o -x assembler /Users/jopepper/Downloads/logistics/Sales.iOS/obj/iPhone/Release/mtouch-cache/arm64/Xamarin.iOS.dll.s
MTOUCH : error MT3001: Could not AOT the assembly '/Users/jopepper/Downloads/logistics/Sales.iOS/obj/iPhone/Release/mtouch-cache/3-Build/Logistics.Sales.dll'

If I comment out one line in Sales.Share/Reports/InventoryReportTemplate.cs:

//#line 6 ""
this.Write("\r\n<Styl|Arial|50|Bold>\r\n<TexC|");

The problem goes away. I don't think I actually know how to fix this, @chamons could this be a problem with Mono AOT in general? I think it's probably something with this #line preprocessor:

https://docs.microsoft.com/dotnet/csharp/language-reference/preprocessor-directives/preprocessor-line

I don't see how the problem could "fix itself" as described in: https://github.com/xamarin/xamarin-macios/issues/8944#issuecomment-650262812

There might be a second problem with incremental builds after a failure.

I'm not sure if I should open a new issue for this or not, but we're seeing this same issue on Microsoft.Diagnostics.Runtime version 2.0.222201

/Users/dean/Projects/osu/osu.iOS/MTOUCH: Error MT3001: Could not AOT the assembly '/Users/dean/Projects/osu/osu.iOS/obj/iPhone/Release/mtouch-cache/3-Build/Microsoft.Diagnostics.Runtime.dll' (MT3001) (osu.iOS)

@peppy

I'm not sure if I should open a new issue for this or not

When in doubt (and even when not too) always open a new issue. It's easy to merge two identical issues, but can turn out very confusing to have two separate problems in the same issue (and most likely one of them will end up not getting fixed).

So please file a new issue, and at the very least attach your diagnostic build log as the new issue template requests.
