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 use variables with no prefix (such as
|
|
dnl CC, CFLAGS, etc.) for the host type as well as the build type,
|
|
dnl because GRUB does not need to use those variables for the build
|
|
dnl type, so there is no conflict. Variables with the prefix "TARGET_"
|
|
dnl (such as TARGET_CC, TARGET_CFLAGS, etc.) are used for the target
|
|
dnl type.
