16 dnl This configure script is complicated, because GRUB needs to deal
17 dnl with three potentially different types:
19 dnl build -- the environment for building GRUB
20 dnl host -- the environment for running utilities
21 dnl target -- the environment for running GRUB
23 dnl In addition, GRUB needs to deal with a platform specification
24 dnl which specifies the system running GRUB, such as firmware.
25 dnl This is necessary because the target type in autoconf does not
26 dnl describe such a system very well.
28 dnl The current strategy is to use variables with no prefix (such as
29 dnl CC, CFLAGS, etc.) for the host type, variables with prefix "BUILD_"
30 dnl (such as BUILD_CC, BUILD_CFLAGS, etc.) for the build type and variables
31 dnl with the prefix "TARGET_" (such as TARGET_CC, TARGET_CFLAGS, etc.) are
32 dnl used for the target type. See INSTALL for full list of variables.
