Follow-up: Report bug to Swift.org; Cannot build project on windows

[Airyzz]

When attempting to build a project on windows, It throws a ton of lld-link warnings, and eventually fails:

note, I didn't include all lld-link warnings, because there are thousands of them

Previously, my project was able to be built for windows via github actions, but it seems now this also does not work

It seems to be getting caught on some part of the generated source
I have attached a screenshot instead of pasting code just to include line numbers:

D:\\testproject\\src\\.build\\plugins\\outputs\\swiftgodot\\SwiftGodot\\CodeGeneratorPlugin\\GeneratedSources\\generated.swift:22774:25

[Airyzz]

Here is a failing build action for extra detail: https://github.com/Airyzz/SwiftGodotCrossBuild/actions/runs/7163879300/job/19503008702

[Airyzz]

Based on my testing here This seems to have been introduced by c24f8b2

I'm hesitant to try and tackle this one myself, as I'm not sure I completely understand what is going on here, but my understanding is something related to withArgPointers is causing issues on windows. It seems if on windows we just use withUnsafePointer it will work ok

cc @pcbeard @migueldeicaza

[tishin]

This snippet is enough to break compilation on Windows:

func withArgPointers(_ args: UnsafeMutableRawPointer?...) {
    print(args)
}
func call() {
    var int: Int = 1
    withArgPointers(&int)
}

Maybe going away from the variadic version to withArgPointers overloads alternative from swiftlang/swift#272 is the way to go, as it seems to work on Windows.

[migueldeicaza]

How can I test for Windows at runtime?

In that case, I can fallback to the old code (which is still present, and used for vararg invocations)

[migueldeicaza]

Band aid applied, I suspect that we should report this to Apple.

[deevus]

This looks like a similar error. Is it related?

C:\Users\Simon\Projects\dwl\MiniMedieval\swift\

@deevus based on this file path, I think your project file path is too long (Swift on windows has issues with long file path See: #271 (comment)). Try moving your project somewhere like C:\MiniMedievaland build from there

[silverhammermba]

At this time, saying SwiftGodot supports Windows is extremely generous at best.

• You basically need subst for builds to work. This should be mentioned in the Windows instructions.

• The build is excruciatingly slow. On Windows 10 with a Ryzen 9 3900 XT a clean build takes 19 minutes. Even worse, incremental builds are just as slow! On my ancient thinkpad running Arch, incremental builds take seconds.

• Incremental builds frequently fail with permission errors:

  lld-link: error: failed to write output 'S:\.build\x86_64-unknown-windows-msvc\debug\SwiftGodotMacroLibrary.exe': permission denied
  or
  lld-link: error: failed to write output 'S:\.build\x86_64-unknown-windows-msvc\debug\SwiftGodot.dll': permission denied
  

  This could be because I set up my extension to load directly from the build directory, but that works fine on Mac and Linux and it's really nice to not have to manually copy files all the time.

SwiftGodot is practically unusable on Windows. The only practical workflow I can see is using Mac/Linux exclusively and then doing a final Windows build only for deployment, which means you effectively cannot collaborate with devs who use Windows exclusively (probably the most common game dev platform).

You basically need subst for builds to work. This should be mentioned in the Windows instructions.

Added to the docs.

The build is excruciatingly slow.

This is something that should be improved upstream, won't be solved here.

This could be because I set up my extension to load directly from the build directory, but that works fine on Mac and Linux and it's really nice to not have to manually copy files all the time.

This is a windows-ism, it does not allow a DLL to be open and written to. On Unix you can, but it can corrupt your running process and crash. The proper procedure is do never do this.

[silverhammermba]

Reported slowdown upstream https://github.com/apple/swift/issues/72221

[migueldeicaza]

One possible workaround is to use precompiled versions of SwiftGodot. I used to use this on MacOS when I didn’t want to rebuild everything all the time. This is the reason I publish binaries for it.

sadly, binary packages are not supported outside macOS, but I ran into this post that shows how folks are working around that limitation. Perhaps we could try something like that:
