[Debian-astro-maintainers] Bug#1001528: FTBFS with eigen3/3.4.0

[Ole Streicher]

Control: forwarded -1 https://github.com/astro-informatics/purify/issues/290

I am afraid that I am unable to fix this: the Debian version of purify 
uses a patched version of Eigen3, and since the patch still succeeds 
(with some offsets) I assume that it is not applied upstream yet.

There is a newer upstream version 3.0.1 of purify (which doesn't require 
the patch); however this doesn't compile for me as well -- with the same 
error as you see now. There are other compilation errors which I saw 
with earlier versions of purify.

These errors were reported upstream already two years ago in

https://github.com/astro-informatics/purify/issues/290

and I also reported some test failures; however without response. The 
last commit in the repository was on May 2021.

Unless the communication with upstream improves, we probably don't get 
this fixed (except you have an idea yourself).

Best

Ole
