From d4ddf22d54f9374715c651aaebda2315e9f89272 Mon Sep 17 00:00:00 2001 From: Mathieu Othacehe Date: Wed, 21 Aug 2019 09:19:58 +0200 Subject: system: vm: Support cross-compilation. * gnu/system.scm (system-linux-image-file-name): Add support for cross-built systems. Remove system argument that was ignored, (operating-system-kernel-file): adapt by removing ignored os argument. * gnu/system/vm.scm (expression->derivation-in-linux-vm): Add target argument and turn inputs into native-inputs. Pass target to qemu-command and gexp->derivation calls. (iso9660-image): Add target argument and pass it to expression->derivation-in-linux-vm. Remove qemu from inputs as it is not necessary. (qemu-image): Add target argument, also remove qemu from inputs. Pass target argument to expression->derivation-in-linux-vm call. --- gnu/system.scm | 15 ++++++++------- gnu/system/vm.scm | 18 +++++++++++++----- 2 files changed, 21 insertions(+), 12 deletions(-) (limited to 'gnu') diff --git a/gnu/system.scm b/gnu/system.scm index a353b1a5c8..96c2b5aad3 100644 --- a/gnu/system.scm +++ b/gnu/system.scm @@ -447,20 +447,21 @@ from the initrd."
