Linking swift-win32 sample code failed

The following are the steps that I have made:

  1. install 'Visual Studio 2019'
  2. Download 'swift-5.3.2-RELEASE-windows10.exe' and install it.
  3. Download 'Windows Software Development Kit 10.0.19041.685' and install it.
  4. Open an 'x64 Native Tools for VS2019 Command Prompt' and execute the copy commands:
copy %SDKROOT%\usr\share\ucrt.modulemap "%UniversalCRTSdkDir%\Include\%UCRTVersion%\ucrt\module.modulemap"
copy %SDKROOT%\usr\share\visualc.modulemap "%VCToolsInstallDir%\include\module.modulemap"
copy %SDKROOT%\usr\share\visualc.apinotes "%VCToolsInstallDir%\include\visualc.apinotes"
copy %SDKROOT%\usr\share\winsdk.modulemap "%UniversalCRTSdkDir%\Include\%UCRTVersion%\um\module.modulemap"
  1. Clone 'swift-win32' project from github.
  2. Execute the following commands:
set SDKROOT=%SystemDrive%/Library/Developer/Platforms/Windows.platform/Developer/SDKs/Windows.sdk
set SWIFTFLAGS=-sdk %SDKROOT% -I %SDKROOT%/usr/lib/swift -L %SDKROOT%/usr/lib/swift/windows

cmake -B build -D BUILD_SHARED_LIBS=YES -D CMAKE_BUILD_TYPE=Release -D CMAKE_Swift_FLAGS="%SWIFTFLAGS%" -G Ninja -S .
ninja -C build SwiftWin32 UICatalog

The cmake command succeeded but the ninja command failed with the following error messages:

Could anyone give some advices?

The following are the swift on my computer:

C:\chenchang\study\swift-win32>swift --version
compnerd.org Swift version 5.3.2 (swift-5.3.2-RELEASE)
Target: x86_64-unknown-windows-msvc

I have intalled the 'Python 3.8' and set 'SWIFTFLAGS' environment variable. When I tried to run swift REPL but the command just exited immediate and nothing happen.

C:\chenchang\study\swift-win32>where python
C:\Users\shche\AppData\Local\Programs\Python\Python38\python.exe
C:\Users\shche\AppData\Local\Microsoft\WindowsApps\python.exe

C:\chenchang\study\swift-win32>echo %SWIFTFLAGS%
-sdk C:\Library\Developer\Platforms\Windows.platform\Developer\SDKs\Windows.sdk -I C:\Library\Developer\Platforms\Windows.platform\Developer\SDKs\Windows.sdk/usr/lib/swift -L C:\Library\Developer\Platforms\Windows.platform\Developer\SDKs\Windows.sdk/usr/lib/swift/windows

C:\chenchang\study\swift-win32>swift repl -target x86_64-unknown-windows-msvc %SWIFTFLAGS%

C:\chenchang\study\swift-win32>

The reason that this fails is that the current development is much further along and requires a newer WinSDK modulemap than what was part of 5.3. The best option IMO is to use the development snapshot (12/14 should be reasonable). My, you can try to play around with the WinSDK module map, but I expect that to be much more difficult.

I tried the following combinations:

swift-5.3.1-RELEASE-Windows10.exe and Windows SDK 10.0.18362.0
swift-5.3.1-RELEASE-Windows10.exe and Windows SDK 10.0.19041.0
swift-5.3.2-RELEASE-Windows10.exe and Windows SDK 10.0.18362.0
swift-5.3.2-RELEASE-Windows10.exe and Windows SDK 10.0.19041.0

This error still exits.

I write a simple Hello.swift file and it can be built:

Hello.swift

print("Hello, world!")
C:\chenchang\study\swift_study>swiftc %SWIFTFLAGS% -emit-executable -o Hello.exe Hello.swift
  正在创建库 Hello.lib 和对象 Hello.exp

C:\chenchang\study\swift_study>hello.exe
hello, world!

Correct, that is exactly expected. The releases that you tried are 5.3, and building the project from the current development state of the tree requires the development snapshot (5.4 pre-releases).
