b977bf01 | 16 | dnl This configure script is complicated, because GRUB needs to deal |
17 | dnl with three potentially different types: | |
18 | dnl | |
19 | dnl build -- the environment for building GRUB | |
20 | dnl host -- the environment for running utilities | |
21 | dnl target -- the environment for running GRUB | |
22 | dnl | |
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. | |
27 | dnl | |
28 | dnl The current strategy is to use variables with no prefix (such as | |
15d76540 DK |
29 | dnl CC, CFLAGS, etc.) for the host and target type, variables with |
30 | dnl prefix "BUILD_" (such as BUILD_CC, BUILD_CFLAGS, etc.) for the | |
31 | dnl build type, variables with prefix "HOST_" (such as HOST_CC, | |
32 | dnl HOST_CFLAGS, etc.) for the host type and variables with the prefix | |
33 | dnl "TARGET_" (such as TARGET_CC, TARGET_CFLAGS, etc.) are used for | |
34 | dnl the target type. See INSTALL for full list of variables and | |
35 | dnl description of the relationships between them. | |
