From 46866fadee576d3c1dfa4b3d3ab819bfae3fdf8b Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Tue, 1 Jan 2013 23:55:40 +0100 Subject: distro: glibc: Build the statically-linked Bash embedded in glibc. * distro/packages/base.scm (glibc): Expect "static-bash" to be a directory, not a single file. Call `remove-store-references' on the "bash" binary that is copied. Add an `sh' -> `bash' symlink. Change the "static-bash" input to (static-package bash-light). (glibc-final): Rename to... (glibc-final-with-bootstrap-bash): ... this. Change `name' to "glibc-intermediate". Remove #:patch-shebangs? setting. (cross-gcc-wrapper): New procedure, with code formerly in GCC-BOOT0-WRAPPED. (gcc-boot0-wrapped): Use it. (static-bash-for-glibc): New variable. (glibc-final): Inherit from GLIBC-FINAL-WITH-BOOTSTRAP-BASH, and use STATIC-BASH-FOR-GLIBC as the "static-bash" input. --- distro/packages/base.scm | 152 +++++++++++++++++++++++++++++++---------------- 1 file changed, 100 insertions(+), 52 deletions(-) (limited to 'distro') diff --git a/distro/packages/base.scm b/distro/packages/base.scm index 4acf4c1538..158a7d2f73 100644 --- a/distro/packages/base.scm +++ b/distro/packages/base.scm @@ -1,5 +1,5 @@ ;;; Guix --- Nix package management from Guile. -*- coding: utf-8 -*- -;;; Copyright (C) 2012 Ludovic Courtès +;;; Copyright (C) 2012, 2013 Ludovic Courtès ;;; Copyright (C) 2012 Nikita Karetnikov ;;; ;;; This file is part of Guix. @@ -528,12 +528,19 @@ (define-public glibc ;; 4.7.1.
