I'll have a look. Thanks! |

Pulling myself off of this - no longer with Apple. |

Comment by Mason Mark (JIRA) I didn't encounter this issue with Swift 3, but now I do see it with Swift 4. Today I tried installing Swift 4.0.2 on a freshly-provisioned Ubuntu Server 16.04 (64-bit) machine. I found that the REPL was broken on Linux in the same well-known way as it is with Swift 3 ("error: could not build C module 'CoreFoundation'"), but after applying the workaround for that issue from SR-2783 (fix permissions of Swift header files after installing), I next encountered the error described in this issue: root@ubuntu:~# /swift/usr/bin/swift
Welcome to Swift version 4.0.2 (swift-4.0.2-RELEASE). Type :help for assistance.

root@ubuntu:~#The fact that this issue's original report was for Swift 3, where I didn't see this issue, and now I see it with Swift 4 on a new, fairly minimal, Ubuntu box, but most people don't (e.g. this thread has somebody reporting this problem, quickly followed by somebody else replying "Hmm doesn't happen to me") makes me think this must be some kind of missing dependency or other environmental issue. But, I haven't found a workaround at this stage, so Swift 4.0.2 isn't working on Ubuntu 16.04 for me (well at least, the REPL isn't). |

Comment by Mason Mark (JIRA) Just as an additional data point: I played around with default installations of various Ubuntu flavors to see where this did and did not happen. One thing I did find is that this error does occur on Ubuntu 17.10 Server, and does not occur on Ubuntu 17.10 Desktop. I know the 17.10 releases aren't "supported" but I thought this still might be helpful, as it seems likely that the difference arises from the Server release missing some package that is pre-installed on the Desktop release. Unfortunately I don't know what package that is; I did |

Comment by Mason Mark (JIRA) OK, I found out This transcript, from a freshly-installed Ubuntu 17.10 server machine, shows the Swift 4.0.2 REPL failing in this manner, and then being fixed by In this example, everything is being done as the root user. The Swift 4.0.2 tarball has been extracted to /swift. The clang headers location is supplied on the command line when invoking swift to work around bug SR-5524. root@ubuntu:~#

Comment by Mason Mark (JIRA) This issue SR-2744 caused by missing libcurl3 dependency; overlaps with the discussion on 2743 |

Comment by Mason Mark (JIRA) Now that I know it's missing libcurl3, a quick search for "swift libcurl3" leads to... the very previous issue to this, SR-2743. That issue's title is probably more relevant than this one's; this issue could be closed as a duplicate of that one, if |

On Ubuntu 16.04, after applying the header permission fix and installing libcurl3, I still can't import Foundation. This bug report is not a duplicate of SR-2743. bouke@ubuntu:~$ swift -version

Comment by Mason Mark (JIRA) @Bouke I see. It looks like you may also need to apply the "clang header location fix" — have you tried that? E.g. pass the path to the clang headers as a command-line argument to swift, something like: swift -I /swift/usr/lib/swift/clang/include/Or, alternatively, by setting these environment variables (taken from this comment by MatiMax (JIRA User)): export C_INCLUDE_PATH=/swift/usr/lib/swift/clang/include/
export CPLUS_INCLUDE_PATH=$C_INCLUDE_PATH(paths will vary depending where you unpacked the swift tarball) I have not yet had a chance to try with Ubuntu Server 16.04, but I find that to get Swift to work on Ubuntu Server I have to do all of these: 1. Do 2. Fix the header permissions (example here) 3. Fix the missing clang headers issue using one of the methods above. Only if I do all three of those things does Swift seem to work on Ubuntu Server or other minimal Ubuntu install. |
