Thanks for all that information. Karlsen et al made their implementation public and open-source, so I should be able to use that in the meantime if I port it to python3. I haven’t been able to get pyGPlates to compile on my computer due to this compilation error, and the installation procedure puts the library in a non-standard location.
Is there a gplates-dev branch for testers or early adopters? I’m using GPlates for my own personal project rather than a research or work project, so I don’t have to worry about deadlines or grant applications or anything like that. I’m also keeping my work in a Git repo so if an experimental application feature eats my work I can always roll back to a previous version if necessary.
