This looks like a missing include. What headers do you include in that
file? I can see that class in `<boost/process/v1/child.hpp>` (the last
place it was documented to be in) in my local copy of Boost. There are
tests that use that class and they pass locally.


That helped. The v1/v2 auto Selection is gone from process.hpp
Including the v1/*.hpp files explicitly (and changing the namespace to boost::process::v1) made the code compile again.
Thanks!
