When I compile from source, I get the error -- -latomic is required to link hhvm.

Hi, this is your first issue on GitHub. Welcome :)

Building hhvm at master using the public build system is very difficult. It has fallen into disrepair. If you checkout HHVM-4.168.4 you should be able to build that tag just fine.

If you want a newer version, this will require you to advance through the mainline commits until your build breaks, then revert until the last working commit, fix the breakage and fast forward.

Keith Adams tried to get an hhvm build going late last year. His fixes can be found here. kmapb@c17d6a2
