Swift tools version misreported

[dabrahams]

$ make

swift build -c release --build-path .build
/Users/dave/src/SourceKittenDaemon: error: package at '/Users/dave/src/SourceKittenDaemon' requires a minimum Swift tools version of 4.0.0 (currently 3.1.0)
make: *** [.build/release/sourcekittend] Error 1

I'm sure this is not a bug in SourceKittenDaemon, but it's blocking me. The only Swift compiler I have is 4.2, so I don't understand the complaint. Any ideas?

[terhechte]

Hm, that's weird. I just tried the above with Swift 4.2(swiftlang-1000.11.37.1 clang-1000.11.45.1) and it worked just fine. Are you building on macOS or Linux?

$ make
mkdir -p .build/release

MacOS

Catching straws here as you know all this much better than me

Does adding verbose swift build -c release --verbose --build-path .build provide hints?

What's weird is that the original make seems to have run just fine. So I'd venture that when you run swift generate-xcodeproj and do xcodebuild or open it in Xcode it also builds fine, right?

Sorry, what's "the original make?"

I guess not!

error: unable to invoke subcommand: /Volumes/Xcode/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-generate-xcodeproj (No such file or directory)

Maybe the necessary facilities are not built into my Apple-internal development Xcode.

[terhechte]

I've created a branch with an added xcodeproj. Does that work (or maybe provide additional hints)?

It might work if I knew how to fetch the dependencies:

Does
swift package resolve
work on your system?

I can't just add the checkouts to the custom branch as they're themselves git repositories. I could zip them and add them if that would work for you.

[rudedogg]

Does the output for the versions of everything look correct?

xcode-select --print-path
xcodebuild -version
swift --version
swift build --version

Probably some overlap checking those, just throwing out ideas and commands :D

[woolsweater]

Looks like a // swift-tools-version:N.N line at the top of Package.swift became mandatory with the Package API redesign. Without it, SPM seems to assume v3.3.1. Additionally, the list of excluded paths for a target was moved from Package to Target after SE-0162 so there are changes needed to the manifest.

Unfortunately, after updating the manifest I am continually getting timeouts during dependency resolution. Mostly -- as far as I can tell -- when the process gets to Clang_C, which seems to be a dependency of SourceKitten. Sometimes it's during a swiftc invocation, but other times git cat-file. Still trying to figure out the issue.
