I am unable to reproduce. Can you run:
swift build -v
and then copy/paste the last line (which should be an invocation of swiftc, to link), and rerun it while also adding "-v"?

Also, what is the output of:
dpkg -l | grep -i stdc

I am try re-run with command
/Desktop/Hello$ swift build -v
/home1/dtcang/Toolchains/swift-2.2-SNAPSHOT-2015-12-01-b-ubuntu14.04/usr/bin/swiftc -o /home1/dtcang/Desktop/Hello/.build/debug/Hello /home1/dtcang/Desktop/Hello/.build/debug/Hello.o/Sources/main.swift.o /home1/dtcang/Desktop/Hello/.build/debug/Hello.o/Sources/Greeter.swift.o -L/usr/local/lib
/usr/bin/ld: cannot find -lstdc++

Hello$ dpkg -l | grep -i stdc
ii libstdc+-4.8-dev:amd64 4.8.4-2ubuntu1~14.04 amd64 GNU Standard C+ Library v3 (development files)
ii libstdc+6:amd64 4.8.4-2ubuntu1~14.04 amd64 GNU Standard C+ Library v3

Can you run:

/home1/dtcang/Toolchains/swift-2.2-SNAPSHOT-2015-12-01-b-ubuntu14.04/usr/bin/swiftc -o /home1/dtcang/Desktop/Hello/.build/debug/Hello /home1/dtcang/Desktop/Hello/.build/debug/Hello.o/Sources/main.swift.o /home1/dtcang/Desktop/Hello/.build/debug/Hello.o/Sources/Greeter.swift.o -L/usr/local/lib -v

and paste the output? It should show the invocation of clang++ it is using to try to link.

Can you also try:

clang++ -shared -x c /dev/null -o /dev/null -lstdc++

which should succeed and verify that your system clang++ is capable of linking. If that doesn't work, this isn't a Swift specific issue...

bump.

Closing due to age. Hopefully this has resolved itself due to the copious number of bug fixes that have landed.
