[swift-users] Building swift with xctest and foundation fails

[Mohit Athwani]

I'm trying to get back to work starting from scratch on Swift Foundation on
my Ubuntu 16.04 LTS system.

I cloned the main swift repo and all of it's dependencies via ssh

./swift/utils/update-checkout --clone-with-ssh

and after running (taken from instructions from the Foundation site):

swift/utils/build-script --xctest --foundation -t

I get the following error:

+ make build-tests
/bin/bash ../libtool  --tag=CC   --mode=link
/home/mohit/Documents/swift-source/build/Ninja-DebugAssert/llvm-linux-x86_64/bin/clang

undefined reference to `objc_release'

invocation)
Makefile:1123: recipe for target 'dispatch_apply' failed
make: *** [dispatch_apply] Error 1
swift/utils/build-script: fatal error: command terminated with a non-zero
exit status 2, aborting

Looks like there is some undefined reference for objc_release in
libswiftCore.

>From the looks of the message it looks like swift was actually built but
it's just that test cases weren't built. On this hunch, I went into my
swift-corelibs-foundation folder and tried to execute:

ninja

Which tells me:

ninja: error: loading 'build.ninja': No such file or directory

Given my lack of experience here, I'm not quite sure how to go about
resolving these issues.

Could somebody help me out here please.

Thanks,

Mohit
