Missing dotnet.wasm when building autogenerated project files #1732

Closed kg closed 2 years ago

kg commented 3 years ago

After I updated to the latest dotnet/performance to work on some benchmarks, I got a new and exciting error:

// Build Error: Exception! 
Message: Could not find file '/home/kate/Projects/performance/artifacts/bin/MicroBenchmarks/Release/net6.0/Job-UGLDFF/bin/net6.0/browser-wasm/publish/dotnet.wasm'.,

Looking at the bin directory i see x86 and amd64 folders with native DLLs in them (this seems wrong?) and none of the wasm related files, not just dotnet.wasm is missing. It seems like for some reason it generated a native build of the benchmark?

The incantation I'm using to build/run the benchmarks is dotnet.sh run -f net6.0 -c Release --runtimes Wasm --cli ~/Projects/dotnet-runtime-wasm/dotnet.sh --wasmMainJs ~/Projects/dotnet-runtime-wasm/src/mono/wasm/runtime-test.js --customRuntimePack ~/Projects/dotnet-runtime-wasm/artifacts/bin/microsoft.netcore.app.runtime.browser-wasm/Release --wasmEngine $V8_PATH ${@:2} in the dotnet/performance repo's latest main rev, 47ed48cf73aeaace0db82d30d9e3f096a2b0b65f, which appears to be using BDN 0.13.0.1559.

I have reproduced this, but I don't know what is going on yet.

Thanks, let me know if I can help with a binlog or something.

@naricc was this fixed by #1734 or these are two different issues?

naricc commented 3 years ago

This is a different issue.

I am unable to reproduce this issue when following instructions provided by @radical in https://github.com/dotnet/performance/pull/2612
