From ea261dea0c581771b4cf297e983f7addc6807051 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Fri, 19 Apr 2019 15:18:20 +0200 Subject: guix build: Accept multiple '-s' options. * guix/scripts/build.scm (%default-options): Remove 'system'. (%options) <--system>: Keep previous occurrences of 'system in RESULT. (options->derivations)[system]: Remove. [systems, things-to-build]: New variables. [compute-derivation]: New procedure. Iterate on all of SYSTEMS to compute the derivations of THINGS-TO-BUILD. * tests/guix-build.sh: Add test for one and multiple '-s' flags. * doc/guix.texi (Additional Build Options): Document this behavior. --- doc/guix.texi | 4 +- guix/scripts/build.scm | 107 +++++++++++++++++++++++++++---------------------- tests/guix-build.sh | 7 ++++ 3 files changed, 70 insertions(+), 48 deletions(-) diff --git a/doc/guix.texi b/doc/guix.texi index 6b713aaf9c..8c7522f286 100644 --- a/doc/guix.texi +++ b/doc/guix.texi @@ -8030,7 +8030,9 @@ The following derivations will be built: @item --system=@var{system} @itemx -s @var{system} Attempt to build for @var{system}---e.g., @code{i686-linux}---instead of -the system type of the build host. +the system type of the build host.
