[swift-dev] More Swift 3 Raspberry Pi 2 build problems

[Eric Wing]

I temporarily hacked around the NSXMLNode.swift integer literal
overflow error I mentioned in the other thread to continue the build.
I hit a few more problems afterwards.


First, there was some kind of segmentation fault. It looks like swift
crashed trying to build libXCTest.so.

==================



I changed the build flags from using the build-bot linux armv7, to
specifying flags so I could skip the XCTest. I then got another crash.
It looks like it is Swift-Build.

==================



I skipped the Swift Build stuff. Finally it gets to the packaging
phase, and something in the packaging phase fails. I think it has
something to do with Python 2.7. I checked the directories and I seem
to have a python 3.4 subdirectory that was created in the Swift
package, but the python 2.7 directory it refers to doesn't exist. (My
Pi has the Python 2.7 packages installed. I think 3 is also
installed.)

I would appreciate any guidance on these.
