dnl This configure script is complicated, because GRUB needs to deal
|
|
|
|
|
dnl with three potentially different types:
|
|
|
|
|
dnl
|
|
|
|
|
dnl build -- the environment for building GRUB
|
|
|
|
|
dnl host -- the environment for running utilities
|
|
|
|
|
dnl target -- the environment for running GRUB
|
|
|
|
|
dnl
|
|
|
|
|
dnl In addition, GRUB needs to deal with a platform specification
|
|
|
|
|
dnl which specifies the system running GRUB, such as firmware.
|
|
|
|
|
dnl This is necessary because the target type in autoconf does not
|
|
|
|
|
dnl describe such a system very well.
|
|
|
|
|
dnl
|
|
|
|
|
dnl The current strategy is to build utilities using host
|
|
|
|
|
dnl cross-compiler and grub core and modules using target
|
|
|
|
|
dnl cross-compiler. For this we use nested packages approach, where
|
|
|
|
|
dnl top-level package grub utilities is built with HOSTCC and nested
|
|
|
|
|
dnl package (in grub-core directory) builds with TARGETCC.
