Unusual REPL failure on Linux


(Fastmail) #1

We’re trying to put Swift inside Docker, and it works for compilation, but crucially the REPL does not:

`error: failed to launch REPL process: process launch failed: 'A' packet returned an error: 8`

If anyone has any suspicions as to the origin of this error, please do let us know. We’re tracking the issue here: https://github.com/swiftdocker/docker-swift/issues/9

(I left work early for this. I am so very happy Swift is OSS now!)

I haven’t seen this before. What version of Linux is being used?

Ubuntu 14.04 LTS, but the dockerized version so presumably missing deps.

Did you install all the deps listed in the Swift README?

Not that they are essential. But perhaps might give us a clue.

Did you install clang? That is definitely a required dependency for using Swift.

(Fastmail) #7

Update:

Works on a local VM, fails on most cloud VMs. Apparently there's a particular restricted flag that needs to be set. Looks like I won't need any more help on this, but thanks for all your input thus far!

I got Swift REPL works just fine on my Koding VM (koding.com). I even
succesfully made an online Swift REPL here:
