Hi Nils, with two dylibs like this, you are basically at the mercy of the linker.
E.g. OS updates often lead to this sort of thing, and indeed you might want to clean and rebuild all the consumers of libflint.so, which you can see by git grep flint build/pkgs/*/dep* (some of these you might not have installed and some might come from OS, so these should be fine) Dima On July 3, 2025 7:25:48 PM CDT, Nils Bruin <nbr...@sfu.ca> wrote: >This ended up not quite working for me anymore.
