To build and use the buildroot stuff, do the following:
1) run 'make'
2) select which packages you wish to compile
3) run 'make'
4) wait while it compiles
5) Use your shiney new root filesystem. Depending on which sortof
root filesystem you selecter, you may want to loop mount it,
chroot into it, loop mount it and then nfs mount that on your
target device, burn it to flash, or whatever is appropriate
for your target system.
You do not need to be root to build or run buildroot. Have fun!

<h2><a name="about" id="about"></a>About Buildroot</h2>
<p>Buildroot is a set of Makefiles and patches that allows to easily
generate both a cross-compilation toolchain and a root filesystem for your
target. The cross-compilation toolchain uses uClibc (<a href=
"http://www.uclibc.org/">http://www.uclibc.org/</a>), a tiny C standard
library.</p>
<p>Buildroot is useful mainly for people working with embedded systems.
Embedded systems often use processors that are not the regular x86
processors everyone is used to have on his PC. It can be PowerPC
processors, MIPS processors, ARM processors, etc.</p>
<p>A compilation toolchain is the set of tools that allows to
compile code for your system. It consists of a compiler (in our
case, <code>gcc</code>), binary utils like assembler and linker
(in our case, <code>binutils</code>) and a C standard library (for
example <a href="http://www.gnu.org/software/libc/libc.html">GNU
Libc</a>, <a href="http://www.uclibc.org">uClibc</a> or <a
href="http://www.fefe.de/dietlibc/">dietlibc</a>). The system
installed on your development station certainly already has a
compilation toolchain that you can use to compile application that
runs on your system. If you're using a PC, your compilation
toolchain runs on an x86 processor and generates code for a x86
processor. Under most Linux systems, the compilation toolchain
uses the GNU libc as C standard library. This compilation
toolchain is called the "host compilation toolchain", and more
generally, the machine on which it is running, and on which you're
working is called the "host system". The compilation toolchain is
provided by your distribution, and Buildroot has nothing to do
with it.</p>
<p>As said above, the compilation toolchain that comes with your system
runs and generates code for the processor of your host system. As your
embedded system has a different processor, you need a cross-compilation
toolchain: it's a compilation toolchain that runs on your host system but
that generates code for your target system (and target processor). For
example, if your host system uses x86 and your target system uses ARM, the
regular compilation toolchain of your host runs on x86 and generates code
for x86, while the cross-compilation toolchain runs on x86 and generates
code for ARM.</p>
<p>Even if your embedded system uses a x86 processor, you might interested
in Buildroot, for two reasons:</p>
<ul>
<li>The compilation toolchain of your host certainly uses the GNU Libc
which is a complete but huge C standard library. Instead of using GNU
Libc on your target system, you can use uClibc which is a tiny C standard
library. If you want to use this C library, then you need a compilation
toolchain to generate binaries linked with it. Buildroot can do it for
you.</li>
<li>Buildroot automates the building of a root filesystem with all needed
tools like busybox. It makes it much easier than doing it by hand.</li>
</ul>
<p>You might wonder why such a tool is needed when you can compile
<code>gcc</code>, <code>binutils</code>, uClibc and all the tools by hand.
Of course, doing so is possible. But dealing with all configure options,
with all problems of every <code>gcc</code> or <code>binutils</code>
version it very time-consuming and uninteresting. Buildroot automates this
process through the use of Makefiles, and has a collection of patches for
each <code>gcc</code> and <code>binutils</code> version to make them work
on most architectures.</p>
<h2><a name="download" id="download"></a>Obtaining Buildroot</h2>
<p>Buildroot is available as daily CVS snapshots or directly using
CVS.</p>
<p>The latest snapshot is always available at <a
href="http://uclibc.org/downloads/snapshots/buildroot-snapshot.tar.bz2">http://uclibc.org/downloads/snapshots/buildroot-snapshot.tar.bz2</a>,
and previous snapshots are also available at <a
href="http://uclibc.org/downloads/snapshots/">http://uclibc.org/downloads/snapshots/</a>.</p>
<p>To download Buildroot using CVS, you can simply follow
the rules described on the "Accessing CVS"-page (<a href=
"http://www.uclibc.org/cvs_anon.html">http://www.uclibc.org/cvs_anon.html</a>)
of the uClibc website (<a href=
"http://www.uclibc.org">http://www.uclibc.org</a>), and download the
<code>buildroot</code> CVS module. For the impatient, here's a quick
recipe:</p>
<pre>
$ cvs -d:pserver:anonymous@uclibc.org:/var/cvs login
$ cvs -z3 -d:pserver:anonymous@uclibc.org:/var/cvs co buildroot
</pre>
<h2><a name="using" id="using"></a>Using Buildroot</h2>
<p>Buildroot has a nice configuration tool similar to the one you can find
in the Linux Kernel (<a href=
"http://www.kernel.org/">http://www.kernel.org/</a>) or in Busybox
(<a href="http://www.busybox.org/">http://www.busybox.org/</a>). Note that
you can run everything as a normal user. There is no need to be root to
configure and use Buildroot. The first step is to run the configuration
assistant:</p>
<pre>
$ make menuconfig
</pre>
<p>For each entry of the configuration tool, you can find associated help
that describes the purpose of the entry.</p>
<p>Once everything is configured, the configuration tool has generated a
<code>.config</code> file that contains the description of your
configuration. It will be used by the Makefiles to do what's needed.</p>
<p>Let's go:</p>
<pre>
$ make
</pre>
<p>This command will download, configure and compile all the selected
tools, and finally generate a target filesystem. The target filesystem will
be named <code>root_fs_ARCH.EXT</code> where <code>ARCH</code> is your
architecture and <code>EXT</code> depends on the type of target filesystem
selected in the <code>Target options</code> section of the configuration
tool.</p>
<h2><a name="custom_targetfs" id="custom_targetfs"></a>Customizing the
target filesystem</h2>
<p>There are two ways to customize the resulting target filesystem:</p>
<ul>
<li>Customize the target filesystem directly, and rebuild the image. The
target filesystem is available under <code>build_ARCH/root/</code> where
<code>ARCH</code> is the chosen target architecture. You can simply make
your changes here, and run make afterwards, which will rebuild the target
filesystem image. This method allows to do everything on the target
filesystem, but if you decide to completely rebuild your toolchain and
tools, these changes will be lost.</li>
<li>Customize the target filesystem skeleton, available under
<code>target/default/target_skeleton/</code>. You can customize
configuration files or other stuff here. However, the full file hierarchy
is not yet present, because it's created during the compilation process.
So you can't do everything on this target filesystem skeleton, but
changes to it remains even you completely rebuild the cross-compilation
toolchain and the tools.<br />
You can also customize the <code>target/default/device_table.txt</code>
file which is used by the tools that generate the target filesystem image
to properly set permissions and create device nodes. The
<code>target/default/skel.tar.gz</code> file contains the main
directories of a root filesystem and there is no obvious reason for which
it should be changed. These main directories are in an tarball inside of
inside the skeleton because it contains symlinks that would be broken
otherwise.</li>
</ul>
<h2><a name="custom_busybox" id="custom_busybox"></a>Customizing the
Busybox configuration</h2>
<p>Busybox is very configurable, and you may want to customize it. You can
follow these simple steps to do it. It's not an optimal way, but it's
simple and it works.</p>
<ol>
<li>Make a first compilation of buildroot with busybox without trying to
customize it.</li>
<li>Go into <code>build_ARCH/busybox/</code> and run <code>make
menuconfig</code>. The nice configuration tool appears and you can
customize everything.</li>
<li>Copy the <code>.config</code> file to
<code>package/busybox/busybox.config</code> so that your customized
configuration will remains even if you remove the cross-compilation
toolchain.</li>
<li>Run the compilation of buildroot again.</li>
</ol>
<p>Otherwise, you can simply change the
<code>package/busybox/busybox.config</code> file if you know the options
you want to change without using the configuration tool.</p>
<h2><a name="custom_uclibc" id="custom_uclibc"></a>Customizing the uClibc
configuration</h2>
<p>Just like <a href="#custom_busybox">BusyBox</a>, <a
href="http://www.uclibc.org">uClibc</a> offers a lot of
configuration options. They allow to select various
functionalities, depending on your needs and limitations.</p>
<p>The easiest way to modify the configuration of uClibc is to
follow these steps :</p>
<ol>
<li>Make a first compilation of buildroot without trying to
customize uClibc.</li>
<li>Go into the directory
<code>toolchain_build_ARCH/uClibc/</code> and run <code>make
menuconfig</code>. The nice configuration assistant, similar to
the one used in the Linux Kernel or in Buildroot appears. Make
your configuration as appropriate.</li>
<li>Copy the <code>.config</code> file to
<code>toolchain/uClibc/uClibc.config</code> or
<code>toolchain/uClibc/uClibc.config-locale</code>. The former
is used if you haven't selected locale support in Buildroot
configuration, and the latter is used if you have selected
locale support.</li>
<li>Run the compilation of Buildroot again</li>
</ol>
<p>Otherwise, you can simply change
<code>toolchain/uClibc/uClibc.config</code> or
<code>toolchain/uClibc/uClibc.config-locale</code> without running
the configuration assistant.</p>
<h2><a name="buildroot_innards" id="buildroot_innards"></a>How Buildroot
works</h2>
<p>As said above, Buildroot is basically a set of Makefiles that download,
configure and compiles software with the correct options. It also includes
some patches for various software, mainly the ones involved in the
cross-compilation tool chain (<code>gcc</code>, <code>binutils</code> and
uClibc).</p>
<p>There is basically one Makefile per software, and they are named with
the <code>.mk</code> extension. Makefiles are split into three
sections:</p>
<ul>
<li><b>package</b> (in the <code>package/</code> directory) contains the
Makefiles and associated files for all user-space tools that Buildroot
can compile and add to the target root filesystem. There is one
sub-directory per tool.</li>
<li><b>toolchain</b> (in the <code>toolchain/</code> directory) contains
the Makefiles and associated files for all software related to the
cross-compilation toolchain : <code>binutils</code>, <code>ccache</code>,
<code>gcc</code>, <code>gdb</code>, <code>kernel-headers</code> and
<code>uClibc</code>.</li>
<li><b>target</b> (in the <code>target</code> directory) contains the
Makefiles and associated files for software related to the generation of
the target root filesystem image. Four types of filesystems are supported
: ext2, jffs2, cramfs and squashfs. For each of them, there's a
sub-directory with the required files. There is also a
<code>default/</code> directory that contains the target filesystem
skeleton.</li>
</ul>
<p>Each directory contains at least 3 files :</p>
<ul>
<li><code>something.mk</code> is the Makefile that downloads, configures,
compiles and installs the software <code>something</code>.</li>
<li><code>Config.in</code> is a part of the configuration tool
description file. It describes the option related to the current
software.</li>
<li><code>Makefile.in</code> is a part of Makefile that sets various
variables according to the configuration given through the configuration
tool. For most tools it simply involves adding the name of the tool to
the <code>TARGETS</code> variable.</li>
</ul>
<p>The main Makefile do the job through the following steps (once the
configuration is done):</p>
<ol>
<li>Create the download directory (<code>dl/</code> by default). This is
where the tarballs will be downloaded. It is interesting to know that the
tarballs are in this directory because it may be useful to save them
somewhere to avoid further downloads.</li>
<li>Create the build directory (<code>build_ARCH/</code> by default,
where <code>ARCH</code> is your architecture). This is where all
user-space tools while be compiled.</li>
<li>Create the toolchain build directory
(<code>toolchain_build_ARCH/</code> by default, where <code>ARCH</code>
is your architecture). This is where the cross compilation toolchain will
be compiled.</li>
<li>Setup the staging directory (<code>build_ARCH/staging_dir/</code> by
default). This is where the cross-compilation toolchain will be
installed. If you want to use the same cross-compilation toolchain for
other purposes, such as compiling third-party applications, you can add
<code>build_ARCH/staging_dir/bin</code> to your PATH, and then use
<code>arch-linux-gcc</code> to compile your application. In order to
setup this staging directory, it first removes it, and then it creates
various subdirectories and symlinks inside it.</li>
<li>Create the target directory (<code>build_ARCH/root/</code> by
default) and the target filesystem skeleton. This directory will contain
the final root filesystem. To setup it up, it first deletes it, then it
uncompress the <code>target/default/skel.tar.gz</code> file to create the
main subdirectories and symlinks, copies the skeleton available in
<code>target/default/target_skeleton</code> and then removes useless
<code>CVS/</code> directories.</li>
<li>Make the <code>TARGETS</code> dependency. This is where all the job
is done : all <code>Makefile.in</code> files "subscribe" targets into
this global variable, so that the needed tools gets compiled.</li>
</ol>
<h2><a name="using_toolchain" id="using_toolchain"></a>Using the
uClibc toolchain</h2>
<p>You may want to compile your own programs or other software
that are not packaged in Buildroot. In order to do this, you can
use the toolchain that was generated by Buildroot.</p>
<p>The toolchain generated by Buildroot by default is located in
<code>build_ARCH/staging_dir/</code>. The simplest way to use it
is to add <code>build_ARCH/staging_dir/bin/</code> to your PATH
environnement variable, and then to use
<code>arch-linux-gcc</code>, <code>arch-linux-objdump</code>,
<code>arch-linux-ld</code>, etc.</p>
<p>For example, you may add the following to your
<code>.bashrc</code> (considering you're building for the MIPS
architecture and that Buildroot is located in
<code>~/buildroot/</code>) :</p>
<pre>
export PATH=$PATH:~/buildroot/build_mips/bin/
</pre>
<p>Then you can simply do :</p>
<pre>
mips-linux-gcc -o foo foo.c
</pre>
<p><b>Important</b> : do not try to move the toolchain to an other
directory, it won't work. There are some hard-coded paths in the
<i>gcc</i> configuration. If the default toolchain directory
doesn't suit your needs, please refer to the <a
href="#toolchain_standalone">Using the uClibc toolchain outside of
buildroot</a> section.</p>
<h2><a name="toolchain_standalone" id="toolchain_standalone"></a>Using the
uClibc toolchain outside of buildroot</h2>
<p>By default, the cross-compilation toolchain is generated inside
<code>build_ARCH/staging_dir/</code>. But sometimes, it may be useful to
install it somewhere else, so that it can be used to compile other programs
or by other users. Moving the <code>build_ARCH/staging_dir/</code>
directory elsewhere is <b>not possible</b>, because they are some hardcoded
paths in the toolchain configuration.</p>
<p>If you want to use the generated toolchain for other purposes,
you can configure Buildroot to generate it elsewhere using the
option of the configuration tool : <code>Build options ->
Toolchain and header file location</code>, which defaults to
<code>$(BUILD_DIR)/staging_dir/</code>.</p>
<h2><a name="downloaded_packages"
id="downloaded_packages"></a>Location of downloaded packages</h2>
<p>It might be useful to know that the various tarballs that are
downloaded by the <i>Makefiles</i> are all stored in the
<code>DL_DIR</code> which by default is the <code>dl</code>
directory. It's useful for example if you want to keep a complete
version of Buildroot which is know to be working with the
associated tarballs. This will allow you to regenerate the
toolchain and the target filesystem with exactly the same
versions.</p>
<h2><a name="add_software" id="add_software"></a>Extending Buildroot with
more software</h2>
<p>This section will only consider the case in which you want to
add user-space software.</p>
<h3>Package directory</h3>
<p>First of all, create a directory under the <code>package</code>
directory for your software, for example <code>foo</code>.</p>
<h3><code>Config.in</code> file</h3>
<p>Then, create a file named <code>Config.in</code>. This file
will contain the portion of options description related to our
<code>foo</code> software that will be used and displayed in the
configuration tool. It should basically contain :</p>
<pre>
config BR2_PACKAGE_FOO
bool "foo"
default n
help
This is a comment that explains what foo is.
</pre>
<p>Of course, you can add other options to configure particular
things in your software.</p>
<h3><code>Makefile.in</code> file</h3>
<p>Then, write a <code>Makefile.in</code> file. Basically, this is
a very short <i>Makefile</i> that adds the name of the software to
the list of <code>TARGETS</code> that Buildroot will generate. In
fact, the name of the software is the the identifier of the target
inside the real <i>Makefile</i> that will do everything (download,
compile, install), and that we study below. Back to
<code>Makefile.in</code>, here is an example :</p>
<pre>
ifeq ($(strip $(BR2_PACKAGE_FOO)),y)
TARGETS+=foo
endif
</pre>
<p>As you can see, this short <i>Makefile</i> simply adds the
target <code>foo</code> to the list of targets handled by Buildroot
if software <i>foo</i> was selected using the configuration tool.</p>
<h3>The real <i>Makefile</i></h3>
<p>Finally, here's the hardest part. Create a file named
<code>foo.mk</code>. It will contain the <i>Makefile</i> rules that
are in charge of downloading, configuring, compiling and installing
the software. Below is an example that we will comment
afterwards.</p>
<pre>

</pre>
<p>First of all, this <i>Makefile</i> example works for a single
binary software. For other software such as libraries or more
complex stuff with multiple binaries, it should be adapted. Look at
the other <code>*.mk</code> files in the <code>package</code>
directory.</p>
<p>At lines 6-11, a couple of useful variables are defined :</p>
<ul>
<li><code>FOO_VERSION</code> : The version of <i>foo</i> that
should be downloaded.</li>
<li><code>FOO_SOURCE</code> : The name of the tarball of
<i>foo</i> on the download website of FTP site. As you can see
<code>FOO_VERSION</code> is used.</li>
<li><code>FOO_SITE</code> : The HTTP or FTP site from which
<i>foo</i> archive is downloaded. It must include the complete
path to the directory where <code>FOO_SOURCE</code> can be
found.</li>
<li><code>FOO_DIR</code> : The directory into which the software
will be configured and compiled. Basically, it's a subdirectory
of <code>BUILD_DIR</code> which is created upon decompression of
the tarball.</li>
<li><code>FOO_BINARY</code> : Software binary name. As said
previously, this is an example for a single binary software.</li>
<li><code>FOO_TARGET_BINARY</code> : The full path of the binary
inside the target filesystem.</li>
</ul>
<p>Lines 13-14 defines a target that downloads the tarball from
the remote site to the download directory
(<code>DL_DIR</code>).</p>
<p>Lines 16-18 defines a target and associated rules that
uncompress the downloaded tarball. As you can see, this target
depends on the tarball file, so that the previous target (line
13-14) is called before executing the rules of the current
target. Uncompressing is followed by <i>touching</i> a hidden file
to mark the software has having been uncompressed. This trick is
used everywhere in Buildroot <i>Makefile</i> to split steps
(download, uncompress, configure, compile, install) while still
having correct dependencies.</p>
<p>Lines 20-31 defines a target and associated rules that
configures the software. It depends on the previous target (the
hidden <code>.source</code> file) so that we are sure the software has
been uncompressed. In order to configure it, it basically runs the
well-known <code>./configure</code>script. As we may be doing
cross-compilation, <code>target</code>, <code>host</code> and
<code>build</code> arguments are given. The prefix is also set to
<code>/usr</code>, not because the software will be installed in
<code>/usr</code> on your host system, but in the target
filesystem. Finally it creates a <code>.configured</code> file to
mark the software as configured.</p>
<p>Lines 33-34 defines a target and a rule that compiles the
software. This target will create the binary file in the
compilation directory, and depends on the software being already
configured (hence the reference to the <code>.configured</code>
file). It basically runs <code>make</code> inside the source
directory.</p>
<p>Lines 36-38 defines a target and associated rules that install
the software inside the target filesystem. It depends on the
binary file in the source directory, to make sure the software has
been compiled. It uses the <code>install</code> target of the
software <code>Makefile</code> by passing a <code>prefix</code>
argument, so that the <code>Makefile</code> doesn't try to install
the software inside host <code>/usr</code> but inside target
<code>/usr</code>. After the installation, the
<code>/usr/man</code> directory inside the target filesystem is
removed to save space.</p>
<p>Line 40 defines the main target of the software, the one
referenced in the <code>Makefile.in</code> file. This targets
should first of all depends on the dependecies of the software (in
our example, <i>uclibc</i> and <i>ncurses</i>), and then to the
final binary. This last dependency will call all previous
dependencies in the right order. </p>
<p>Line 42 defines a simple target that only downloads the code
source. This is not used during normal operation of Buildroot, but
might be useful.</p>
<p>Lignes 44-46 define a simple target to clean the software build
by calling the <i>Makefiles</i> with the appropriate option.</p>
<p>Lines 48-49 define a simple target to completely remove the
directory in which the software was uncompressed, configured and
compiled.</p>
<h3>Conclusion</h3>
<p>As you can see, adding a software to buildroot is simply a
matter of writing a <i>Makefile</i> using an already existing
example and to modify it according to the compilation process of
the software.</p>
<p>If you package software that might be useful for other persons,
don't forget to send a patch to Buildroot developers !</p>

Introduction
------------
The configuration database is collection of configuration options
organized in a tree structure:
+- Code maturity level options
| +- Prompt for development and/or incomplete code/drivers
+- General setup
| +- Networking support
| +- System V IPC
| +- BSD Process Accounting
| +- Sysctl support
+- Loadable module support
| +- Enable loadable module support
| +- Set version information on all module symbols
| +- Kernel module loader
+- ...
Every entry has its own dependencies. These dependencies are used
to determine the visible of an entry. Any child entry is only
visible if its parent entry is also visible.
Menu entries
------------
Most entries define a config option, all other entries help to organize
them. A single configuration option is defined like this:
config MODVERSIONS
bool "Set version information on all module symbols"
depends MODULES
help
Usually, modules have to be recompiled whenever you switch to a new
kernel. ...
Every line starts with a key word and can be followed by multiple
arguments. "config" starts a new config entry. The following lines
define attributes for this config option. Attributes can be the type of
the config option, input prompt, dependencies, help text and default
values. A config option can be defined multiple times with the same
name, but every definition can have only a single input prompt and the
type must not conflict.
Menu attributes
---------------
A menu entry can have a number of attributes. Not all of them are
applicable everywhere (see syntax).
- type definition: "bool"/"tristate"/"string"/"hex"/"integer"
Every config option must have a type. There are only two basic types:
tristate and string, the other types base on these two. The type
definition optionally accepts an input prompt, so these two examples
are equivalent:
bool "Networking support"
and
bool
prompt "Networking support"
- input prompt: "prompt" <prompt> ["if" <expr>]
Every menu entry can have at most one prompt, which is used to display
to the user. Optionally dependencies only for this prompt can be added
with "if".
- default value: "default" <symbol> ["if" <expr>]
A config option can have any number of default values. If multiple
default values are visible, only the first defined one is active.
Default values are not limited to the menu entry, where they are
defined, this means the default can be defined somewhere else or be
overriden by an earlier definition.
The default value is only assigned to the config symbol if no other
value was set by the user (via the input prompt above). If an input
prompt is visible the default value is presented to the user and can
be overridden by him.
Optionally dependencies only for this default value can be added with
"if".
- dependencies: "depends on"/"requires" <expr>
This defines a dependency for this menu entry. If multiple
dependencies are defined they are connected with '&&'. Dependencies
are applied to all other options within this menu entry (which also
accept "if" expression), so these two examples are equivalent:
bool "foo" if BAR
default y if BAR
and
depends on BAR
bool "foo"
default y
- help text: "help"
This defines a help text. The end of the help text is determined by
the level indentation, this means it ends at the first line which has
a smaller indentation than the first line of the help text.
Menu dependencies
-----------------
Dependencies define the visibility of a menu entry and can also reduce
the input range of tristate symbols. The tristate logic used in the
expressions uses one more state than normal boolean logic to express the
module state. Dependency expressions have the following syntax:
<expr> ::= <symbol> (1)
<symbol> '=' <symbol> (2)
<symbol> '!=' <symbol> (3)
'(' <expr> ')' (4)
'!' <expr> (5)
<expr> '||' <expr> (6)
<expr> '&&' <expr> (7)
Expressions are listed in decreasing order of precedence.
(1) Convert the symbol into an expression. Boolean and tristate symbols
are simply converted into the respective expression values. All
other symbol types result in 'n'.
(2) If the values of both symbols are equal, it returns 'y',
otherwise 'n'.
(3) If the values of both symbols are equal, it returns 'n',
otherwise 'y'.
(4) Returns the value of the expression. Used to override precedence.
(5) Returns the result of (2-/expr/).
(6) Returns the result of min(/expr/, /expr/).
(7) Returns the result of max(/expr/, /expr/).
An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2
respectively for calculations). A menu entry becomes visible when it's
expression evaluates to 'm' or 'y'.
There are two type of symbols: constant and nonconstant symbols.
Nonconstant symbols are the most common ones and are defined with the
'config' statement. Nonconstant symbols consist entirely of alphanumeric
characters or underscores.
Constant symbols are only part of expressions. Constant symbols are
always surrounded by single or double quotes. Within the quote any
other character is allowed and the quotes can be escaped using '\'.
Menu structure
--------------
The position of a menu entry in the tree is determined in two ways. First
it can be specified explicitely:
menu "Network device support"
depends NET
config NETDEVICES
...
endmenu
All entries within the "menu" ... "endmenu" block become a submenu of
"Network device support". All subentries inherit the dependencies from
the menu entry, e.g. this means the dependency "NET" is added to the
dependency list of the config option NETDEVICES.
The other way to generate the menu structure is done by analyzing the
dependencies. If a menu entry somehow depends on the previous entry, it
can be made a submenu of it. First the the previous (parent) symbol must
be part of the dependency list and then one of these two condititions
must be true:
- the child entry must become invisible, if the parent is set to 'n'
- the child entry must only be visible, if the parent is visible
config MODULES
bool "Enable loadable module support"
config MODVERSIONS
bool "Set version information on all module symbols"
depends MODULES
comment "module support disabled"
depends !MODULES
MODVERSIONS directly depends on MODULES, this means it's only visible if
MODULES is different from 'n'. The comment on the other hand is always
visible when MODULES it's visible (the (empty) dependency of MODULES is
also part of the comment dependencies).
Kconfig syntax
--------------
The configuration file describes a series of menu entries, where every
line starts with a keyword (except help texts). The following keywords
end a menu entry:
- config
- choice/endchoice
- comment
- menu/endmenu
- if/endif
- source
The first four also start the definition of a menu entry.
config:
"config" <symbol>
<config options>
This defines a config symbol <symbol> and accepts any of above
attributes as options.
choices:
"choice"
<choice options>
<choice block>
"endchoice"
This defines a choice group and accepts any of above attributes as
options. A choice can only be of type bool or tristate, while a boolean
choice only allows a single config entry to be selected, a tristate
choice also allows any number of config entries to be set to 'm'. This
can be used if multiple drivers for a single hardware exists and only a
single driver can be compiled/loaded into the kernel, but all drivers
can be compiled as modules.
A choice accepts another option "optional", which allows to set the
choice to 'n' and no entry needs to be selected.
comment:
"comment" <prompt>
<comment options>
This defines a comment which is displayed to the user during the
configuration process and is also echoed to the output files. The only
possible options are dependencies.
menu:
"menu" <prompt>
<menu options>
<menu block>
"endmenu"
This defines a menu block, see "Menu structure" above for more
information. The only possible options are dependencies.
if:
"if" <expr>
<if block>
"endif"
This defines an if block. The dependency expression <expr> is appended
to all enclosed menu entries.
source:
"source" <prompt>
This reads the specified configuration file. This file is always parsed.

/*
* Changes by Clifford Wolf (god@clifford.at)
*
* [ 1998-06-13 ]
*
* *) A bugfix for the Page-Down problem
*
* *) Formerly when I used Page Down and Page Up, the cursor would be set
* to the first position in the menu box. Now lxdialog is a bit
* smarter and works more like other menu systems (just have a look at
* it).
*
* *) Formerly if I selected something my scrolling would be broken because
* lxdialog is re-invoked by the Menuconfig shell script, can't
* remember the last scrolling position, and just sets it so that the
* cursor is at the bottom of the box. Now it writes the temporary file
* lxdialog.scrltmp which contains this information. The file is
* deleted by lxdialog if the user leaves a submenu or enters a new
* one, but it would be nice if Menuconfig could make another "rm -f"
* just to be sure. Just try it out - you will recognise a difference!
*
* [ 1998-06-14 ]
*
* *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
* and menus change their size on the fly.
*
* *) If for some reason the last scrolling position is not saved by
* lxdialog, it sets the scrolling so that the selected item is in the
* middle of the menu box, not at the bottom.
*
* 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
* Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
* This fixes a bug in Menuconfig where using ' ' to descend into menus
* would leave mis-synchronized lxdialog.scrltmp files lying around,
* fscanf would read in 'scroll', and eventually that value would get used.

# When building a target filesystem, it is desirable to not have to
# become root and then run 'mknod' a thousand times. Using a device
# table you can create device nodes and directories "on the fly".
#
# This is a sample device table file for use with genext2fs. You can
# do all sorts of interesting things with a device table file. For
# example, if you want to adjust the permissions on a particular file
# you can just add an entry like:
# /sbin/foobar f 2755 0 0 - - - - -
# and (assuming the file /sbin/foobar exists) it will be made setuid
# root (regardless of what its permissions are on the host filesystem.
# Furthermore, you can use a single table entry to create a many device
# minors. For example, if I wanted to create /dev/hda and /dev/hda[0-15]
# I could just use the following two table entries:
# /dev/hda b 640 0 0 3 0 0 0 -
# /dev/hda b 640 0 0 3 1 1 1 15
#
# Device table entries take the form of:
# <name> <type> <mode> <uid> <gid> <major> <minor> <start> <inc> <count>
# where name is the file name, type can be one of:
# f A regular file
# d Directory
# c Character special device file
# b Block special device file
# p Fifo (named pipe)
# uid is the user id for the target file, gid is the group id for the
# target file. The rest of the entries (major, minor, etc) apply only
# to device special files.
# Have fun
