Cannot import Foundation in REPL

[jeremyblalock]

Using the instructions found in #9 I have successfully run a REPL, but when trying to import Foundation, I get the following error:

$ docker run --cap-add sys_ptrace --privileged -it --rm swiftdocker/swift swift
Welcome to Swift version 4.0 (swift-4.0-RELEASE). Type :help for assistance.

Is this expected? Should I be able to import Foundation, or am I required to create a separate image and install Foundation there?

Doing some research, it looks like this issue has been researched and "resolved" here: https://bugs.swift.org/browse/SR-5686.

So What do we need to do to update the documentation / Dockerfile to get this to work?

[jeremyblalock]

Resolved this issue, but we should update documentation to reflect the need to add to the search path. The following works properly from within the container:

$ swift -I /usr/lib/swift/clang/include/

@jeremyblalock a PR to the readme would be much appreciated :)

It's not entirely clear to me if/how they've fixed the issue in the Swift project. However, we definitely need a note to be added about this.

BTW, this work around also solved my problem of having import SwiftGlibc fail.

[john9631]

Still present (Linux Mint 18.3 (U 16.04 based)) so added alias to my .zshrc

alias swift='swift -I ~/.local/usr/lib/swift/clang/include'

But given that virtually everything I tried that relied on it didn't work ... I'd say this is not ready on Linux. I might look again in 2019.

@jeremyblalock We are moving Swift Docker issues to https://bugs.swift.org Component: Docker. Can you please file your issue on bugs.swift.org?

We are planning on closing GitHub swift-docker issues on Dec 20th, 2018 (PST).

This issue is very old - please reopen if it's still a problem.
