ninja: build stopped: subcommand failed.

Hmm, did you checkout the sources in the correct mode? It could be that you checked out the sources with CRLF line endings rather than LF. I remember that there was something similar to this that I was hitting due to a bug in the location tracking work that IIRC @David_Ungar2 was working on.

I would recommend that you build off of master for the time being.

@compnerd Thanks for the response. I followed instructions from the build guide here. I see only 2 repos are being cloned with -c core.autocrlf=input should I checkout other repos as well ?.

I am getting the same error on the master branch as well. I tried to compare my logs with the CI build and your azure pipeline logs but was not able to see any major different expect the failures on my end.

What am I missing?

Cant really tell from just the snippet. I would try to reproduce the build at the exact revision + version of VS2019. You could try building the compiler without assertions (though, I do generally build with assertions, so Im not sure why you are hitting an assertion when the other builds do not).

@compnerd Hopefully, this is useful for you to replicate my env. Please let me know if you need more information.

However, I have noticed a difference between my logs and CI logs. I see a few things that are disabled in CI are enabled in my build as you can see below in the output. I don't know how it got enabled if you can tell me how to disable them, I can try to build. Or it doesn't affect the build.

Hmm, the latter error is interesting. Are you sure that you are on the right branch for all the projects? It sounds like your llvm-project checkout might be at the wrong revision.

double checked all branches are correct swift-5.2, I let me do a build again on master.

@compnerd Sadly, I am still getting the same error on master as well.
for 'min(_:_:)' (at C:/Users/PKS/swift-base/toolchain/swift/stdlib/public/core/Algorithm.swift:20:8)

Let me know if you need the full console logs, I have saved it. Seems like I can't attache txt files here.

I don’t think that the console logs will help here. It would need to be the full build tree, so that the error can be diagnosed. I’m really curious as to what is the difference between the bullies. Can you get the version of the toolset? That might be a difference.

  • Visual Studio 2019 (16.4.1)
  • Windows 10 SDK (10.0.17763.0)
  • Windows 10 SDK (10.0.18362.0)
  • MSVC v142 - VS C ++ x64/x86 build tools (14.24)

Based on the docs these are the only relevant packages. Let me know if I have missed a package/tool I will get the version.

The MSVC Toolset version is going to be more than just 14.24 when you are building. But, that version of VS2019 is what I am using personally, so Im very confused as to what is different.

14.24.28314 I believe, Based on the path its installed C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.24.28314/bin/Hostx64/x64/cl.exe
or maybe 19.24.28314

Sorry about this getting dropped. I am wondering if you are still encountering this issue. We should ensure that the problem is resolved if it has not already been.
