<pre>am trying to create a swift-lang package for arch linux, with a continuous
build here: <a href="https://github.com/soloturn/swift-aur/actions">https://github.com/soloturn/swift-aur/actions</a>
funny is that on arch linux which first has newest packages, and second, dev
packages do not exist, there is just one package including the developer
version in many cases.
compiler-rt can be built with g++, but using clang++ fails
$ export CC=clang
$ export CC=clang
$ makepkg -s
and it really gives the same error when compiling swift.
