[Windows] regression: `swift --version`, `swift build` does not output anything to console and returns immediately #80356

bkhouri · 2025-03-27T23:30:50Z

Description

There appears to have been a regression on the nightly main Windows toolchain sometime between March 10 and March 25, 2025 OSS toolchain, where running swift build in a directory containing a Package.swift outputs nothing to the console and returns immediately.

Reproduction

Installed the Windows nightly Swift Toolchain using the executable
Open a new Powershell window
Clone a repository that has a Package.swift (I cloned https://github.com/swiftlang/swift-package-manager)
Change to that directory
Run swift build

Expected behavior

A build starts, but nothing happens.

Environment

PS C:\Users\bkhouri\Documents\git\swift-package-manager> swiftc -version
PS C:\Users\bkhouri\Documents\git\swift-package-manager>
PS C:\Users\bkhouri> swift --version
PS C:\Users\bkhouri> swift build --version
PS C:\Users\bkhouri> cd .\Documents\git\swift-package-manager\
PS C:\Users\bkhouri\Documents\git\swift-package-manager> swift build --version
PS C:\Users\bkhouri\Documents\git\swift-package-manager> swift build
PS C:\Users\bkhouri\Documents\git\swift-package-manager> git remote -v

PS C:\Users\bkhouri\Documents\git\swift-package-manager>

Additional information

I installed the x86_64 exe installer
Once the issue is fixed, we need to revert Pin Windows nightly images to 3/10 snapshot swift-docker#453

Analyzed the toolchain at https://download.swift.org/development/windows10/swift-DEVELOPMENT-SNAPSHOT-2025-03-25-a/swift-DEVELOPMENT-SNAPSHOT-2025-03-25-a-windows10.exe and confirmed that there are a mix of x86_64 and aarch64 binaries. This is an x86_64 toolchain, yet:

./Runtimes/0.0.0/usr/bin/plutil.exe: PE32+ executable (console) Aarch64, for MS Windows

./Runtimes/0.0.0/usr/bin/_FoundationICU.dll: PE32+ executable (DLL) (GUI) Aarch64, for MS Windows

The compiler runtimes appear correct:

./Runtimes/0.0.0/usr/bin/concrt140.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows
./Runtimes/0.0.0/usr/bin/msvcp140_1.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows

./Runtimes/0.0.0/usr/bin/msvcp140_codecvt_ids.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows
./Runtimes/0.0.0/usr/bin/msvcp140.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows
./Runtimes/0.0.0/usr/bin/vccorlib140.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows
./Runtimes/0.0.0/usr/bin/vcruntime140_1.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows
./Runtimes/0.0.0/usr/bin/vcruntime140_threads.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows
./Runtimes/0.0.0/usr/bin/vcruntime140.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows

And the toolchain content is all x86_64. So it seems just the runtime part has the wrong arch.

@compnerd Any idea what might've went wrong here which went in between March 10th and 25th?

jakepetroules · 2025-03-28T00:00:21Z

Perhaps #80024 could be related?

compnerd · 2025-03-28T01:26:42Z

It might be related to that PR - I have a follow up that I am working on right now. This sounds like there is an issue with the DLLs which are being packaged up.

bkhouri · 2025-03-28T19:47:22Z

once the issue is fixed, we will need to revert swiftlang/swift-docker#453 to ensure the Windows docker image are no longer pinned to an "older" toolchain version

compnerd · 2025-03-28T20:48:57Z

I think that #80157 might fix the issue. Longer term, we need to figure out how to do some smoke testing for Windows with the toolchain itself.

@compnerd : I don't think #80157 fixed the issue. Installing the June 9 main nightly toolchain does not yield any results when running swift --version

compnerd · 2025-06-10T17:36:18Z

@bkhouri that doesn't make sense - I just installed that locally in a Windows Sandbox:

C:\Users\WDAGUtilityAccount>swiftc -v
Swift version 6.2-dev (LLVM 3c4a54b02dd62b7, Swift a40a7be6945a895)
Target: x86_64-unknown-windows-msvc

C:\Users\WDAGUtilityAccount>swift --version
Swift version 6.2-dev (LLVM 3c4a54b02dd62b7, Swift a40a7be6945a895)
Target: x86_64-unknown-windows-msvc
Build config: +assertions

bkhouri · 2025-06-10T17:40:43Z

Just tried re-installing and it's working now.
