3 This is the GRUB. Welcome.
5 This file contains instructions for compiling and installing the GRUB.
10 GRUB depends on some software packages installed into your system. If
11 you don't have any of them, please obtain and install them before
16 * GNU Bison 2.3 or later
17 * GNU gettext 0.17 or later
18 * GNU binutils 2.9.1.0.23 or later
19 * Flex 2.5.35 or later
20 * Other standard GNU/Unix tools
22 On GNU/Linux, you also need:
24 * libdevmapper 1.02.34 or later (recommended)
26 To build grub-emu, you need:
29 * libusb (recommended)
32 To build GRUB's graphical terminal (gfxterm), you need:
37 If you use a development snapshot or want to hack on GRUB you may
40 * Python 2.5.2 or later
41 * Autoconf 2.60 or later
42 * Automake 1.10.1 or later
43 * Autogen 5.10 or later
45 Prerequisites for make-check:
47 * qemu, specifically the binary 'qemu-system-i386'
52 The `configure' shell script attempts to guess correct values for
53 various system-dependent variables used during compilation. It uses
54 those values to create a `Makefile' in each directory of the package.
55 It may also create one or more `.h' files containing system-dependent
56 definitions. Finally, it creates a shell script `config.status' that
57 you can run in the future to recreate the current configuration, a
58 file `config.cache' that saves the results of its tests to speed up
59 reconfiguring, and a file `config.log' containing compiler output
60 (useful mainly for debugging `configure').
62 If you need to do unusual things to compile the package, please try to
63 figure out how `configure' could check whether to do them, and mail
64 diffs or instructions to the address given in the `README' so they can
65 be considered for the next release. If at some point `config.cache'
66 contains results you don't want to keep, you may remove or edit it.
68 The file `configure.ac' is used to create `configure' by a program
69 called `autoconf'. You only need `configure.in' if you want to change
70 it or regenerate `configure' using a newer version of `autoconf'.
76 The simplest way to compile this package is:
78 1. `cd' to the directory containing the package's source code. If
79 you don't use a release tarball you have to type `./autogen.sh'.
80 Type `./configure' to configure the package for your system.
81 If you're using `csh' on an old version of System V, you might
82 need to type `sh ./configure' instead to prevent `csh' from trying
83 to execute `configure' itself.
85 Running `configure' takes awhile. While running, it prints some
86 messages telling which features it is checking for.
88 2. Type `make' to compile the package.
90 3. Optionally, type `make check' to run any self-tests that come with
93 4. Type `make install' to install the programs and any data files and
96 5. You can remove the program binaries and object files from the
97 source code directory by typing `make clean'. To also remove the
98 files that `configure' created (so you can compile the package for
99 a different kind of computer), type `make distclean'. There is
100 also a `make maintainer-clean' target, but that is intended mainly
101 for the package's developers. If you use it, you may have to get
102 all sorts of other programs in order to regenerate files that came
103 with the distribution.
106 Compiling For Multiple Architectures
107 ====================================
109 You can compile the package for more than one kind of computer at the
110 same time, by placing the object files for each architecture in their
111 own directory. `cd' to the directory where you want the object files
112 and executables to go and run the `configure' script. `configure'
113 automatically checks for the source code in the directory that
114 `configure' is in and in `..'.
120 By default, `make install' will install the package's files in
121 `/usr/local/bin', `/usr/local/man', etc. You can specify an
122 installation prefix by giving `configure' the option `--prefix=PATH'.
124 You can specify separate installation prefixes for
125 architecture-specific files and architecture-independent files. If
126 you give `configure' the option `--exec-prefix=PATH', the package will
127 use PATH as the prefix for installing programs and libraries.
128 Documentation and other data files will still use the regular prefix.
130 In addition, if you use an unusual directory layout you can give
131 options like `--bindir=PATH' to specify different values for
132 particular kinds of files. Run `configure --help' for a list of the
133 directories you can set and what kinds of files go in them.
135 If the package supports it, you can cause programs to be installed
136 with an extra prefix or suffix on their names by giving `configure'
137 the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
139 Please note, however, that the GRUB knows where it is located in the
140 filesystem. If you have installed it in an unusual location, the
141 system might not work properly, or at all. The chief utility of these
142 options for the GRUB is to allow you to "install" in some alternate
143 location, and then copy these to the actual root filesystem later.
149 If you want to set default values for `configure' scripts to share,
150 you can create a site shell script called `config.site' that gives
151 default values for variables like `CC', `cache_file', and `prefix'.
152 `configure' looks for `PREFIX/share/config.site' if it exists, then
153 `PREFIX/etc/config.site' if it exists. Or, you can set the
154 `CONFIG_SITE' environment variable to the location of the site script.
155 A warning: not all `configure' scripts look for a site script.
161 `configure' recognizes the following options to control how it
165 Use and save the results of the tests in FILE instead of
166 `./config.cache'. Set FILE to `/dev/null' to disable caching, for
167 debugging `configure'.
170 Print a summary of the options to `configure', and exit.
175 Do not print messages saying which checks are being made.
178 Look for the package's source code in directory DIR. Usually
179 `configure' can determine that directory automatically.
182 Print the version of Autoconf used to generate the `configure'
