Subject: [PATCH core-updates 0/4] Enable cross-Compilation for
 python-pycryptodome
Date: Mon, 16 Jan 2023 00:09:42 -0500

This is an example making use of the recent changes proposed for pyproject,
enabling cross compilation for the pyproject-build-system packages (see:
https://issues.guix.gnu.org/60847).  You can test it like:

./pre-inst-env guix build --target=aarch64-linux-gnu python-pycryptodome

And inspect the produced C libraries part of the package match the expected
architecture.


Maxim Cournoyer (4):
  gnu: libtommath: Update to 1.2.0-0.03de03d.
  gnu: libtomcrypt: Update to 1.18.2-0.29986d0.
  gnu: python-pycryptodome: Fix build and enable cross-compilation.
  gnu: python-coverage: Switch to pyproject-build-system.
