Dear maintainer,
xsimd provides a unique API for SIMD instructions among different
processor architectures. Additionally to many specific architectures,
there is also a fallback scalar option for unsupported architectures (as
far as I interpret the headers).
Currently, xsimd-dev fails to build on armel, armhf, mips64el, mipsel,
ppc64el, s390x (armhf is built with 8.0.3-1 on experimental).
xsimd-dev is build dependency of pythran, which makes pythran
uninstallable on the platforms where xsimd-dev fails.
In turn, python3-pythran is a new build dependency of skimage (0.19.2).
The current version of skimage (0.18.3) is now starting to collect RC
bugs because of incompatibilities with newer pil and tifffile versions
(#1009431, #1010430).
skimage is also one of the basic scientific Python packages which is
expected to be available on all platforms.
Therefore, could I ask to provide xsimd-dev for all platforms, using the
scalar fallback for unsupported CPUs?
Best regards
Ole
