Bug#894574: Please add support for riscv64 architecture
Package: python-numpy
Version: 1:1.13.3-2
Severity: wishlist
Tags: patch upstream
User: debian-riscv@lists.debian.org
Usertags: riscv64
Hi,
We are in the process of bootstrapping a Debian port for the
riscv64 architecture (https://wiki.debian.org/RISC-V). It happens that
python-numpy needs a patch to support this architecture, which has just
been merged upstream:
https://github.com/numpy/numpy/commit/718d9e866b8f49a6898d267ed45306c08410e86c
The patch doesn't apply cleanly on the version 1.13.3 which is in
Debian, so I have backported the patch. You'll find it attached.
Would it be possible to include it in the next upload?
Thanks,
Aurelien
