Enable SwiftCompilerSources on Windows #73247

eeckstein · 2024-04-25T09:17:51Z

With some hacks and workarounds I could get SwiftCompilerSources working on my local Windows machine.
To-do: also enable it in lldb (see my comment in the top-level CMakeLists file).

CMakeLists.txt

lldb is not built before swift, it is built alongside as a single unified build. This implies that there is a missing dependency in the LLDB build definition.

Thanks for clarifying. I updated the comment (We can fix the underlying problem in a follow-up PR).

Statically linking the standard library is not supported - how do we ensure that this is not applied to it?

Hm, I thought that -static means that the currently built module is statically linked. The option is applied to the SwiftCompilerSources modules (and not to the stdlib).
Anyway, without this option it doesn't work and with this option it works.

Ah, okay, this flag is only applied to SwiftCompilerSources? If so, that should be fine. I just wanted to ensure that it didn't accidentally leak. You are correct that it only applies to the module that you are building.

You should be able to implement this with the Win32 + ucrt APIs to convert the stderr handle to a FILE *.

If this works on newer compilers, perhaps we should also include a version check?

I still need to check if it works with newer compilers

This is likely another missing dependency in the build graph (CC: @etcwilde). The build is shuffled on differently on different hosts. The dependencies should be accurate to avoid these types of spurious failures.

I already fixed it. I was using some wrong build options
