Descrizione
Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?
- Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands,
swift build,swift test,swift packageetc.
Description
This is a re-write of https://github.com/swiftlang/swift/issues/90687, because I’ve been told the package manager is a better location for the bug.
Setup:
A package that has a target (e.g. Dest) depending on non-Swift target(s) (e.g. Dep1 and Dep2, tested with C, ObjC), and whose target(s) do not contain a module.modulemap.
Issue:
Running swift run --repl gives a REPL in which Dest cannot be imported (we get a “missing required module” error, for the modules Dep1 and Dep2, other dependencies work fine).
Expected behavior
The import should work.
Actual behavior
We get the error missing required modules: 'CMacroExports', 'CNSTaskHelptender'.
Steps to reproduce
- git clone https://github.com/xcode-actions/swift-process-invocation.git
- cd swift-process-invocation
- swift run --repl
- Once in the REPL (if you can get there; there is another issue that can prevent getting there, but relaunching should do the trick), try to
import ProcessInvocation.
