ChimeraX Developer Meeting

Attendance: Eric, Zach, Tom, Greg

June 12, 2023

Agenda

• ChimeraX Protein Science paper outline
• Update Mac Intel build machine?

Zach: I think I fixed the build failures on Essex2. They ended up being that the Python 3.11 archive uses some header format that the old version of bsdtar on Mojave doesn’t know about, and that the Python 3.11 archive is universal2-only, so bundle builder was trying to build intel-arm binaries without the arm Xcode libraries available on the machine (they first appear in Xcode 12, compatible with 10.15 and up, but we run Xcode 11 on 10.14). We might consider updating Essex2 from 10.14 soon, at least to Catalina but preferably to Big Sur, since we’re soon to be 5(!) versions behind when Sonoma releases.

Eric: Essex2 is also the Chimera build machine
