Message #602 received at 74290 <at> debbugs.gnu.org (full text, mbox):

From: Janneke Nieuwenhuizen <janneke <at> gnu.org>
To: 74290 <at> debbugs.gnu.org
Subject: [PATCH v4 52/58] gnu: Use gcc-14, gcc-toolchain-14 on the 64bit Hurd.
Date: Sun, 24 Nov 2024 08:55:15 +0100

This enables building packages in a 64bit childhurd.  It will not enable
offloading to a childhurd.

* guix/utils.scm (host-hurd?, host-x86-64, host-hurd64?): New procedures.
* gnu/packages/commencement.scm (gcc-toolchain): Use them to determine if the
host is a 64bit Hurd, and use gcc-toolchain-14.
* gnu/packages/gcc.scm (gcc): Likewise, to use gcc-14.
