bugs: ABI incompatibility after 1.5.0 release #47

Problems

It is from diffpy/diffpy.srreal#85

yes. Libdiffpy has been changed to be compatible with nanobind. We need to think a bit about this because this may not be backwards compatible so we need to make sure that everything works. If someone installs a version of srreal that uses boost then it needs to load the old version of libdiffpy but if it loads a version of srreal that uses nanobind, it loads the new version. Please could we look into how to handle that elegantly?

Solution

There is a closely related FAQ in the Conda-forge documentation How to handle breaking of a package due to ABI incompatibility?

In summary:

• update the setup.py in the diffpy.srreal.
• Hot-fix the published version of diffpy.srreal to pin the version of libdiffpy by Repodata patching
• Add run_export in libdiffpy's meta.yaml in the next release
  If we plan to add libdiffpy to conda-forge-pinning, create PR to Conda-forge-pinning-feedstock
