Hello there!

Ubuntu is currently disabling the build on s390x, and I've also seen that some other more obscure arches are not building in Debian.
Upstream clearly states in its README that big endian processors are currently not supported. [1]

Would you consider disabling the build on unsupported architectures, so that downstream distributions can avoid carrying a delta?

Thanks
Skia

Please don't. There is a pseudo package for exactly this purpose called

	architecture-is-little-endian

Please just build-depend on that.

Thanks,
Adrian

Thanks for the pointer, I forgot about that.

In the meantime, I've also learned that Ubuntu packages absolutely don't need a delta for such changes, so it's been dropped already, and we're back in sync.

Feel free to close the bug, since in the end, it seems no one (humans or bots) really cares about such build failures.

Indeed, the consensus in Debian is that you shouldn't do this if the 
build fails on those architectures (which is does). For reference, see: 
https://www.debian.org/doc/manuals/developers-reference/pkgs.html#being-kind-to-porters 
point 9.

Thanks for the detailed reference, that makes perfect sense!
