hi Andy, This would indicate a problem with your environment -- this would affect any project that uses CMake and not only Arrow. It looks that you have multiple versions of CMake installed (3.5 and 3.13.2) and they are conflicting with each other. Ubuntu Xenial has CMake 3.5
https://launchpad.net/ubuntu/xenial/+source/cmake I would suggest scrubbing your system of the other version of CMake - Wes On Sun, Jan 13, 2019 at 6:33 PM Andrew Palumbo <[email protected]> wrote: > > I understans that you are in the middle of a release, and I have been > following along with builds of of different commits.
