The grub-help list came through with an alternative approach: "./configure CC=powerpc-linux-gcc --host=ppc-linux-gnu --target=i386 --with-platform=pc TARGET_CC=i386-linux-gcc" This would allow for building on a host of arch ppc for a target of arch i386. Would it be preferable then to build this as a target package and manipuate the configure flags to use the BUILD_CC ? I presume a similar PN rename would be desirable to account for the HOST component of the build as I used here for the TARGET on the -native version? -- Darren > > Care is taken to ensure changing targets will force a rebuild of this > native recipe by including the target arch in the PN. > > Signed-off-by: Darren Hart <dvh...@linux.intel.com> > --- > meta/recipes-bsp/grub/grub-efi-native_1.99.bb | 74 > +++++++++++++++++++++++++ > 1 files changed, 74 insertions(+), 0 deletions(-) > create mode 100644 meta/recipes-bsp/grub/grub-efi-native_1.99.bb > > diff --git a/meta/recipes-bsp/grub/grub-efi-native_1.99.bb > b/meta/recipes-bsp/grub/grub-efi-native_1.99.bb > new file mode 100644 > index 0000000..3c52ec9 > --- /dev/null > +++ b/meta/recipes-bsp/grub/grub-efi-native_1.99.bb > @@ -0,0 +1,74 @@ > +SUMMARY = "GRUB2 is the next-generation GRand Unified Bootloader" > + > +DESCRIPTION = "GRUB2 is the next generaion of a GPLed bootloader \ > +intended to unify bootloading across x86 operating systems.
