Missing run_exports?

Comment:

Hiya,

As this is a C++ library, should the feedstock have run_exports? I've run into issues where xtensor and xsimd versions are incompatible (both installed from conda-forge).

These are pure headers libraries, therefore run export does not really make sense.

xsimd is an optional dependency of xtensor; to guarantee compatibility between the packages, conda-forge provides the run_constrained feature, which we use in the feedstock of xtensor.

The issue you experienced is probably due to a wrong version pinning in the run_constrained, or even the lack or run_constraints in older versions of the xtensor feedstock.

Ok, thanks, all good then!
