Does not build under Linux

[idcrook]

Not sure if this is a requirement for this project-- or is supported-- but wanted to put an issue out there. It might never be supported.

I do not need this for myself as I can build/run SwiftPlate on macOS, and once I have the boilerplate build, I can use git clones to share in Linux environment.

building under linux

I tried to build SwiftPlate from recent clone on Linux (Ubuntu 16.04), and get build errors. Most of them look like they are Swift Core library/Foundation related, which is known to be lagging in completeness compared to macOS/*OS.

$ swift ../SwiftPlate/main.swift test
../SwiftPlate/main.swift:56:16: error: value of type 'ObjCBool' (aka 'Bool') has no member 'boolValue'
        return objCBool.boolValue
               ^~~~~~~~ ~~~~~~~~~
../SwiftPlate/main.swift:176:19: error: use of unresolved identifier 'Process'
    let process = Process()
                  ^~~~~~~
Foundation.NSProgress:1:12: note: did you mean 'NSProgress'?
open class NSProgress : Foundation.NSObject {
           ^
Foundation.ProcessInfo:1:12: note: did you mean 'ProcessInfo'?
open class ProcessInfo : Foundation.NSObject {
           ^

Process changed to CommandLine?

I didn't really dig much into these errors. Googling the Process() one yielded something that would appear to related, but after further investigation, I do not think it is: Rename Process to CommandLine [SE-0086] https://github.com/apple/swift/commit/f65c1390cb23395fde5a798fb6731b32a31ec452

The change referred to has been in place for a while on Swift 3 branch.

I was able to confirm that Process is available in Foundation on macOS, but is not present in Foundation on Linux (at this time).

Process changed to CommandLine?

Process in Swift 3 on macOS was previously NSTask (SE-0086). But on Linux, the type is still defined as Task (just dropped NS prefix), not as Process in swift-corelibs-foundation.

I created this issue more to document the build status under Linux. Since it appears at least partly due to Foundation lagging behind under Linux Swift, it would seem low ROI to spend time trying to to get this work, at least for now. Perhaps at some future time, we could revisit? I would be fine with closing this issue.

Closing issue. Perhaps revisit when Foundation framework has caught up under Linux.
