From 23a3a3c746261c3ecb2aa961d91f988f0602a032 Mon Sep 17 00:00:00 2001 From: Sam Thursfield Date: Wed, 14 Jun 2017 22:58:52 +0100 Subject: Support cross-building the stage1 and stage2 components This requires a feature recently added to BuildStream (in commit 03906221) that adds a framework for elements to support being cross-compiled. To build an armv8l64 native toolchain and sysroot on an x86_64 build machine, for example, you can do this: bst build --target-arch=armv8l64 gnu-toolchain/stage2.bst You can then run `bst checkout` to get at the resulting binaries and copy them onto an armv8l64 machine where they can be executed. --- elements/gnu-toolchain/stage1-gcc.bst | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'elements/gnu-toolchain/stage1-gcc.bst') diff --git a/elements/gnu-toolchain/stage1-gcc.bst b/elements/gnu-toolchain/stage1-gcc.bst index 8e9eadfd..bcf30bc3 100644 --- a/elements/gnu-toolchain/stage1-gcc.bst +++ b/elements/gnu-toolchain/stage1-gcc.bst @@ -43,7 +43,7 @@ config: # without an existing libc, and generally try to keep this build as # simple as possible. - | - case "%{bst-arch}" in + case "%{bst-target-arch}" in armv7lhf) ARCH_FLAGS="--with-arch=armv7-a \ --with-cpu=cortex-a9 \ --with-tune=cortex-a9 \ @@ -89,7 +89,7 @@ config: # code results on an undefined reference to `__gmpn_invert_limb' in # ARMv7.
