[swift-corelibs-dev] Foundation build failing

2017-03-23 Thread David Dunn via swift-corelibs-dev 
Hi,

I've downloaded the latest Xcode (beta 5), using the
swift-3.1-DEVELOPMENT-SNAPSHOT-2017-03-19-a
toolchain and also pulled down the latest code from Apple master but when I
run the build in Xcode it fails with the following errors:


Undefined symbols for architecture x86_64:

  "__T015SwiftFoundation014__CFInitializeA0yyF", referenced from:

  ___CFInitialize in libCoreFoundation.a(CFRuntime.o)

  "__T015SwiftFoundation21__CFSwiftGetBaseClasss9AnyObject_pXpyF",
referenced from:

  ___CFInitialize in libCoreFoundation.a(CFRuntime.o)

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see
invocation)


A colleague also sees this problem, can anyone else reproduce it and does
anyone know how to fix it?

Thanks,
David

This is because mangling changed and that was pushed before the toolchain
was updated to the new mangling.

[swift-corelibs-dev] CharacterSet Issues

2017-03-29 Thread David Dunn via swift-corelibs-dev 
Hey,

I noticed there's a lot of bugs within CharacterSet at the moment some of
which I've started to look at. In particular I've been looking at SR-3485
(CharacterSet.isSuperset(of:) returns wrong result on Linux), alongside
this I've noticed there's various others such as SR-3282, SR-3825 and
SR-2956 to name a few.

I've tracked the SR-3485 issue down into the CoreFoundation code and just
need to spend some time understanding what the C code is doing exactly and
why it's returning the incorrect value.

During my investigation into SR-3485 I stumbled upon SR-3311 where Philippe
Hausler mentioned Tony Parker was working on a set of fixes for the
CharacterSet issues, I found more information about this on a PR (#6044
) against apple/swift, I also
found Tony's branch
 for
the refactor of CharacterSet. So firstly I was wondering if there has been
any update on this recently? And is this a planned fix for all of the
current issues in CharacterSet?

Thanks,
David

[swift-corelibs-dev] Unable to Build swift-corelibs-foundation

2017-05-18 Thread David Dunn via swift-corelibs-dev 
I've pulled down all the latest changes from
https://github.com/apple/swift-corelibs-foundation and currently using the
latest toolchain (Swift Development Snapshot 2017-05-16).
However various errors arise when trying to build.

I get numerous errors that are similar to this:
swift-corelibs-foundation/Foundation/Data.swift:63:41: '>>' is unavailable
'>>' was obsoleted in Swift 4

And this error also occurs:
swift-corelibs-foundation/Foundation/NSArray.swift:375:157: Contextual
closure type '(UnsafeMutableRawPointer, Int) -> Void' expects 2 arguments,
but 1 was used in closure body

I was wondering if anyone knew a way around these errors? Or is there's
something I'm doing wrong.

Thanks.
