From 6dff905e51202bbdebbad8811b6509584d12a796 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ludovic=20Court=C3=A8s?= Date: Sun, 3 Sep 2017 14:25:39 +0200 Subject: gnu: glibc: Add "static" output. This shrinks glibc:out from 37 MiB to 29 MiB. * gnu/packages/base.scm (glibc/linux)[outputs]: Add "static". [arguments]: Add #:modules. Add 'move-static-libs' phase. * gnu/packages/commencement.scm (static-bash-for-glibc): Augment #:configure-flags to pass "-L LIBC:STATIC". Add the "static" output of GLIBC-FINAL to 'inputs'. (%boot2-inputs, %final-inputs): Likewise. (canonical-package): Adjust to deal with multiple-output packages. * gnu/packages/cross-base.scm (cross-gcc): Add the "static" output of LIBC to 'native-inputs'. --- gnu/packages/base.scm | 49 +++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 47 insertions(+), 2 deletions(-) (limited to 'gnu/packages/base.scm') diff --git a/gnu/packages/base.scm b/gnu/packages/base.scm index 532bb3e95b..ef81f2069f 100644 --- a/gnu/packages/base.scm +++ b/gnu/packages/base.scm @@ -542,7 +542,8 @@ store.") ;; users should automatically pull Linux headers as well.
