[PATCH] gnu: Add support for the 'armhf-linux' system |
|
Date: |
Wed, 07 Jan 2015 12:57:11 -0500 |
Hello Guix,
This patch adds support for the 'armhf-linux' system. It is for
core-updates. The attached patch is excerpted, for review purposes.
It is missing the bootstrap binaries, since they are quite large.
Comments and suggestions welcome!
Mark

Subject: [PATCH] gnu: Add support for the 'armhf-linux' system.
Based on preliminary work by John Darrington <address@hidden>.
* gnu/packages/bootstrap/armhf-linux/bash,
gnu/packages/bootstrap/armhf-linux/mkdir,
gnu/packages/bootstrap/armhf-linux/tar,
gnu/packages/bootstrap/armhf-linux/xz: New files.
* gnu-system.am (bootstrap_armhf_linuxdir, dist_bootstrap_armhf_linux_DATA)
(nodist_bootstrap_armhf_linux_DATA): New variables.
(DISTCLEANFILES): Add $(nodist_bootstrap_armhf_linux_DATA).
(gnu/packages/bootstrap/armhf-linux/guile-2.0.11.tar.xz): New target.
* build-aux/download.scm (file-name->uri): Use newer date in URI for
armhf-linux.
* gnu/packages/bootstrap.scm (raw-build): Use "guile-2.0.11.tar.xz" on
armhf-linux.
(glibc-dynamic-linker, %bootstrap-coreutils&co, %bootstrap-binutils)
(%bootstrap-glibc, %bootstrap-gcc): Add armhf-linux cases.
* .gitignore: Add gnu/packages/bootstrap/armhf-linux/guile-2.0.11.tar.xz.
* gnu/packages/gcc.scm (gcc-configure-flags-for-triplet): Add armhf case.
(gcc-4.7)[pre-configure]: Add gcc/config/*/linux-eabi.h to the list
of files in which to patch GLIBC_DYNAMIC_LINKER.
* gnu/packages/cross-base.scm (xgcc-armhf): New variable.
* guix/utils.scm (gnu-triplet->nix-system, nix-system->gnu-triplet):
Add armhf cases.
* m4/guix.m4 (GUIX_SYSTEM_TYPE): Add armhf case.
(GUIX_ASSERT_SUPPORTED_SYSTEM): Add armhf-linux to list of
supported systems.
* doc/guix.texi (GNU Distribution): Add armhf-linux to the list of
supported systems.
