This system will contain just enough tools to start +constructing the final LFS system in and allow a working environment +with more user convenience than a minimum environment would. + +There are two steps in building this minimal system. The first +step is to build a new and host-independent toolchain (compiler, +assembler, linker, libraries, and a few useful utilities). The second +step uses this toolchain to build the other essential tools. + +The files compiled in this chapter will be installed under the +$LFS/tools directory to keep +them separate from the files installed in the next chapter and the +host production directories. Since the packages compiled here are +temporary, we do not want them to pollute the soon-to-be LFS +system. + +Before issuing the build instructions for a package, the package +should be unpacked as user lfs, and a +cd into the created directory should be performed. The build +instructions assume that the bash shell is in use. + +Several of the packages are patched before compilation, but only +when the patch is needed to circumvent a problem. A patch is often +needed in both this and the next chapter, but sometimes in only one or +the other. Therefore, do not be concerned if instructions for a downloaded +patch seem to be missing. Warning messages about +offset or fuzz may +also be encountered when applying a patch. Do not worry about these +warnings, as the patch was still successfully applied. + +During the compilation of most packages, there will be several +warnings that scroll by on the screen. These are normal and can safely +be ignored. These warnings are as they appear—warnings about +deprecated, but not invalid, use of the C or C++ syntax. C standards +change fairly often, and some packages still use the older standard. +This is not a problem, but does prompt the warning. + +After installing each package, delete its source and build +directories, unless specifically instructed otherwise. Deleting the +sources saves space and prevents mis-configuration when the same +package is reinstalled later. Only three of the packages need to +retain the source and build directories in order for their contents to +be used by later commands.

It is not essential to +immediately understand everything in this section. Most of this +information will be clearer after performing an actual build. This +section can be referred back to at any time during the process. + +The overall goal of is +to provide a temporary environment that can be chrooted into and from +which can be produced a clean, trouble-free build of the target LFS +system in . Along the way, we +separate from the host system as much as possible, and in doing so, +build a self-contained and self-hosted toolchain. It should be noted +that the build process has been designed to minimize the risks for new +readers and provide maximum educational value at the same time. In +other words, more advanced techniques could be used to build the +system. + + +Before continuing, be aware of the name of the working platform, +often referred to as the target triplet. Many times, the target +triplet will probably be i686-pc-linux-gnu. A +simple way to determine the name of the target triplet is to run the +config.guess script that comes with the source for +many packages. Unpack the Binutils sources and run the script: +./config.guess and note the output. + +Also be aware of the name of the platform's dynamic linker, +often referred to as the dynamic loader (not to be confused with the +standard linker ld that is part of Binutils). The +dynamic linker provided by Glibc finds and loads the shared libraries +needed by a program, prepares the program to run, and then runs it. +The name of the dynamic linker will usually be +ld-linux.so.2. On platforms that are less +prevalent, the name might be ld.so.1, +and newer 64 bit platforms might be named something else entirely. The name of +the platform's dynamic linker can be determined by looking in the +/lib directory on the host +system. A sure-fire way to determine the name is to inspect a random +binary from the host system by running: readelf -l <name +of binary> | grep interpreter and noting the output. +The authoritative reference covering all platforms is in the +shlib-versions file in the root of the Glibc +source tree. + + +Some key technical points of how the build +method works: + + +The process is similar in principle to +cross-compiling, whereby tools installed in the same prefix work in +cooperation, and thus utilize a little GNU +magic + +Careful manipulation of the standard linker's library +search path ensures programs are linked only against chosen +libraries + +Careful manipulation of gcc's +specs file tell the compiler which target dynamic +linker will be used + + +Binutils is installed first because the +./configure runs of both GCC and Glibc perform +various feature tests on the assembler and linker to determine which +software features to enable or disable. This is more important than +one might first realize. An incorrectly configured GCC or Glibc can +result in a subtly broken toolchain, where the impact of such breakage +might not show up until near the end of the build of an entire +distribution. A test suite failure will usually alert this error +before too much additional work is performed. + +Binutils installs its assembler and linker in two locations, +/tools/bin and /tools/$TARGET_TRIPLET/bin. The tools in +one location are hard linked to the other. An important facet of the +linker is its library search order. Detailed information can be +obtained from ld by passing it the +--verbose flag. For example, an ld +--verbose | grep SEARCH will illustrate the current search +paths and their order. It shows which files are linked by +ld by compiling a dummy program and passing the +--verbose switch to the linker. For example, +gcc dummy.c -Wl,--verbose 2>&1 | grep +succeeded will show all the files successfully opened +during the linking. + +The next package installed is GCC. An example of what can be +seen during its run of ./configure is: + +checking what assembler to use... + /tools/i686-pc-linux-gnu/bin/as +checking what linker to use... /tools/i686-pc-linux-gnu/bin/ld + +This is important for the reasons mentioned above. It also +demonstrates that GCC's configure script does not search the PATH +directories to find which tools to use. However, during the actual +operation of gcc itself, the same +search paths are not necessarily used. To find out which standard +linker gcc will use, run: gcc +-print-prog-name=ld. + +Detailed information can be obtained from gcc +by passing it the -v command line option while +compiling a dummy program. For example, gcc -v +dummy.c will show detailed information about the +preprocessor, compilation, and assembly stages, including +gcc's included search paths and their order. + +The next package installed is Glibc. The most important +considerations for building Glibc are the compiler, binary tools, and +kernel headers. The compiler is generally not an issue since Glibc +will always use the gcc found in a +PATH directory. +The binary tools and kernel headers can be a bit more complicated. +Therefore, take no risks and use the available configure switches to +enforce the correct selections. After the run of +./configure, check the contents of the +config.make file in the glibc-build directory for all important +details. Note the use of CC="gcc -B/tools/bin/" +to control which binary tools are used and the use of the +-nostdinc and -isystem +flags to control the compiler's include search path. These items +highlight an important aspect of the Glibc package—it is very +self-sufficient in terms of its build machinery and generally does not +rely on toolchain defaults. + +After the Glibc installation, make some adjustments to ensure +that searching and linking take place only within the /tools prefix. Install an adjusted +ld, which has a hard-wired search path limited to +/tools/lib. Then amend +gcc's specs file to point to the new dynamic linker +in /tools/lib. This last step +is vital to the whole process. As mentioned above, a hard-wired path +to a dynamic linker is embedded into every Executable and Link Format +(ELF)-shared executable. This can be inspected by running: +readelf -l <name of binary> | grep +interpreter. Amending gcc's specs file +ensures that every program compiled from here through the end of this +chapter will use the new dynamic linker in /tools/lib. + +The need to use the new dynamic linker is also the reason why +the Specs patch is applied for the second pass of GCC. Failure to do +so will result in the GCC programs themselves having the name of the +dynamic linker from the host system's /lib directory embedded into them, which +would defeat the goal of getting away from the host. + +During the second pass of Binutils, we are able to utilize the +--with-lib-path configure switch to control +ld's library search path. From this point onwards, +the core toolchain is self-contained and self-hosted. The remainder of +the packages all build +against the new Glibc in /tools. + +Upon entering the chroot environment in , the first major package to be +installed is Glibc, due to its self-sufficient nature mentioned above. +Once this Glibc is installed into /usr, perform a quick changeover of the +toolchain defaults, then proceed in building the rest of the target +LFS system. + + +Notes on Static Linking + +Besides their specific task, most programs have to perform many +common and sometimes trivial operations. These include allocating +memory, searching directories, reading and writing files, string +handling, pattern matching, arithmetic, and other tasks. Instead of +obliging each program to reinvent the wheel, the GNU system provides +all these basic functions in ready-made libraries. The major library +on any Linux system is Glibc. + +There are two primary ways of linking the functions from a +library to a program that uses them—statically or dynamically. When +a program is linked statically, the code of the used functions is +included in the executable, resulting in a rather bulky program. When +a program is dynamically linked, it includes a reference to the +dynamic linker, the name of the library, and the name of the function, +resulting in a much smaller executable. A third option is to use the +programming interface of the dynamic linker (see the +dlopen man page for more information). + +Dynamic linking is the default on Linux and has three major +advantages over static linking. First, only one copy of the executable +library code is needed on the hard disk, instead of having multiple +copies of the same code included in several programs, thus saving +disk space. Second, when several programs use the same library +function at the same time, only one copy of the function's code is +required in core, thus saving memory space. Third, when a library +function gets a bug fixed or is otherwise improved, only the one +library needs to be recompiled instead of recompiling all programs +that make use of the improved function. + +If dynamic linking has several advantages, why then do we +statically link the first two packages in this chapter? The reasons +are threefold—historical, educational, and technical. The +historical reason is that earlier versions of LFS statically linked +every program in this chapter. Educationally, knowing the difference +between static and dynamic linking is useful. The technical benefit is +a gained element of independence from the host, meaning that those +programs can be used independently of the host system. However, it is +worth noting that an overall successful LFS build can still be +achieved when the first two packages are built dynamically. + + + diff --git a/chapter05/udev.xml b/chapter05/udev.xml deleted file mode 100644 index 0809dfd53..000000000 --- a/chapter05/udev.xml +++ /dev/null @@ -1,40 +0,0 @@ - - - %general-entities; -]> - -Udev-&udev-version; - - - - -<segmentedlist> -<segtitle>&buildtime;</segtitle> -<segtitle>&diskspace;</segtitle> -<seglistitem><seg>0.2 SBU</seg><seg>5.2 MB</seg></seglistitem> -</segmentedlist> - -</sect2> - -<sect2 role="installation"> -<title>Installation of Udev - -The following patch makes Udev respect the DESTDIR variable: - -patch -Np1 -i ../udev-&udev-version;-DESTDIR-1.patch - -Now compile Udev: - -make prefix=/tools udevdir=/dev - -Install the package: - -make DESTDIR=/tools udevdir=/dev install - -cp ../udev-config-2.permissions /tools/etc/udev/permissions.d/00-lfs.permissions -cp ../udev-config-1.rules /tools/etc/udev/rules.d/00-lfs.rules - - - - diff --git a/chapter05/util-linux.xml b/chapter05/util-linux.xml index 4349f326f..1c0ae3c19 100644 --- a/chapter05/util-linux.xml +++ b/chapter05/util-linux.xml @@ -7,7 +7,12 @@ Util-linux-&util-linux-version; + +Util-linux +tools + +<xi:include xmlns:xi="http://www.w3.org/2003/XInclude" href="../chapter06/util-linux.xml" xpointer="xpointer(/sect1/sect2[1]/para[1])"/> <segmentedlist> <segtitle>&buildtime;</segtitle> @@ -15,12 +20,16 @@ <seglistitem><seg>0.2 SBU</seg><seg>16 MB</seg></seglistitem> </segmentedlist> +<xi:include xmlns:xi="http://www.w3.org/2003/XInclude" href="../chapter06/util-linux.xml" xpointer="xpointer(/sect1/sect2[1]/segmentedlist[2])"/> + </sect2> <sect2 role="installation"> <title>Installation of Util-linux -Issue a sed sustitution: +Util-linux does not use the freshly installed headers and +libraries from the /tools +directory.

That is, we chroot into the +temporary mini Linux system, make a few final preparations, and then +begin installing the packages. + +The installation of this software is straightforward. Although +in many cases the installation instructions could be made shorter and +more generic, we have opted to provide the full instructions for every +package to minimize the possibilities for mistakes. The key to +learning what makes a Linux system work is to know what each package +is used for and why the user (or the system) needs it. For every +installed package, a summary of its contents is given, followed by +concise descriptions of each program and library the package +installed. + +If using the compiler optimizations provided in this chapter, +please review the optimization hint at . Compiler optimizations can make +a program run slightly faster, but they may also cause compilation +difficulties and problems when running the program. If a package +refuses to compile when using optimization, try to compile it without +optimization and see if that fixes the problem. Even if the package +does compile when using optimization, there is the risk it may have +been compiled incorrectly because of the complex interactions between +the code and build tools. The small potential gains achieved in using +compiler optimizations are often outweighed by the risks. First-time +builders of LFS are encouraged to build without custom optimizations. +The subsequent system will still run very fast and be stable at the +same time. + +The order that packages are installed in this chapter needs to +be strictly followed to ensure that no program accidentally acquires a +path referring to /tools +hard-wired into it. For the same reason, do not compile packages in +parallel. Compiling in parallel may save time (especially on dual-CPU +machines), but it could result in a program containing a hard-wired +path to /tools, which will +cause the program to stop working when that directory is +removed. + +Before the installation instructions, each installation page +provides information about the package, including a concise +description of what it contains, approximately how long it will take +to build, how much disk space is required during this building +process, and any other packages needed to successfully build the +package. Following the installation instructions, there is a list of +programs and libraries (along with brief descriptions of these) that +the package installs. + +To keep track of which package installs particular files, a package +manager can be used. For a general overview of different styles of package +managers, please refer to . +For a package management method specifically geared towards LFS, we recommend . + +The remainder of this book is to be performed while logged +in as user root and no longer as user +lfs. + diff --git a/chapter06/iproute2.xml b/chapter06/iproute2.xml index 3cce62619..cf492bd64 100644 --- a/chapter06/iproute2.xml +++ b/chapter06/iproute2.xml @@ -3,16 +3,17 @@ %general-entities; ]> - -Iproute2-&iproute2-version; + + Iproute2-&iproute2-version; - - iproute2 + Iproute2 - + <para>The Iproute2 package contains programs for basic and advanced + IPV4-based networking. + </para> <segmentedlist> <segtitle>&buildtime;</segtitle> <segtitle>&diskspace;</segtitle> @@ -21,42 +22,244 @@ <seg>.6 MB</seg> </seglistitem> </segmentedlist> - + <segmentedlist> + <segtitle>Iproute2 installation depends on</segtitle> + <seglistitem> + <seg>GCC, Glibc, Make, Linux-Headers, and Sed</seg> + </seglistitem> + </segmentedlist> </sect2> - <sect2 role="installation"> <title>Installation of Iproute2 - - Apply a patch + The arpd binary included in this package is + dependent on Berkeley DB.

It has also been marked +as deprecated due to a lack of recent maintenance. + +With the development of the unstable 2.5 kernel tree, later +released as the 2.6 series of stable kernels, a new virtual filesystem +called sysfs came to be. +The job of sysfs is to +export a view of the system's structure to userspace processes. With +this userspace visible representation, the possibility of seeing a +userspace replacement for devfs became much more +realistic. + + + +Udev Implementation + +The sysfs filesystem +was mentioned briefly above. One may wonder how sysfs knows about the devices present +on a system and what device numbers should be used. Drivers that +have been compiled into the kernel directly register their objects +with sysfs as they are +detected by the kernel. For drivers compiled as modules, this will +happen when the module is loaded. Once the sysfs filesystem is mounted (on +/sys), the data which the +built-in drivers registered with sysfs are available to userspace +processes and to udev for device node creation. + +The S10udev initscript takes care of creating +these device nodes when Linux is booted. This script starts with +registering /sbin/udev as a hotplug event handler. +Hotplug events (discussed below) should not be generated during this +stage, but udev is registered just in case they do +occur. The udevstart program then walks through +the /sys filesystem and +creates devices under /dev that +match the descriptions. For example, +/sys/class/tty/vcs/dev contains the string +7:0 This string is used by udevstart +to create /dev/vcs with major number +7 and minor 0. The +permissions of each and every device that udevstart +creates are set using files from the /etc/udev.d/permissions.d/ directory. +These are numbered in a similar fashion to the LFS bootscripts. If +udev cannot find a permissions file for the device +it is creating, it will default permissions to +600 and ownership to +root:root. The names of the nodes created under +the /dev directory are +configured according to the rules specified in the files within the +/etc/udev/rules.d/ +directory. + +Once the above stage is complete, all devices that were already +present and have compiled-in drivers will be available for use. What +about those devices that have modular drivers? + +Earlier, we mentioned the concept of a hotplug event +handler. When a new device connection is detected by the +kernel, the kernel will generate a hotplug event and look at the file +/proc/sys/kernel/hotplug to find out the +userspace program that handles the device's connection. The +udev initscript registered udev +as this handler. When these hotplug events are generated, the kernel +will tell udev to check the /sys filesystem for the information +pertaining to this new device and create the /dev entry for it. + +This brings us to one problem that exists with +udev, and likewise with devfs before it. It is commonly +referred to as the chicken and egg problem. Most Linux +distrubtions handle loading modules via entries in +/etc/modules.conf. Access to a device node causes +the appropriate kernel module to load. With udev, +this method will not work because the device node does not exist until +the module is loaded. To solve this, the +S05modules bootscript was added to the +lfs-bootscripts package, along with the +/etc/sysconfig/modules file. By +adding module +names to the modules file, these modules will be +loaded when the computer is starting up. This allows +udev to detect the devices and create the +appropriate device nodes. + +Note that on slower machines or for drivers that create a lot +of device nodes, the process of creating devices may take a few +seconds to complete. This means that some device nodes may not be +immediately accessible. + + + +Handling Hotpluggable/Dynamic Devices + +When you plug in a device, such a Universal Serial Bus (USB) MP3 player, the kernel +recognizes that the device is now connected and generates a hotplug +event. If the driver is already loaded (either because it was compiled +into the kernel or because it was loaded via the +S05modules bootscript), udev will +be called upon to create the relevant device node(s) according to the +sysfs data available in +/sys. If the driver for the +just plugged in device is available as a module but currently unloaded, +then attaching the device to the system will only cause the kernel's +bus driver to generate a hotplug event that notifies userspace of the +new device connection and it not being attached to a driver. In +effect, nothing happens and the device itself is not usable +yet. + +If building a system that has a lot of drivers compiled as +modules rather than directly built into the kernel, using the +S05modules may not be practical. The Hotplug +package (see ) can +be beneficial in these cases. When the Hotplug package is installed, +it will respond to the aforementioned kernel's bus driver hotplug +events. The Hotplug package will load the appropriate module and make +this device available by creating the device node(s) for it. + + + +Problems with Creating Devices + +There are a few known problems when it comes to automatically creating +devices nodes: + +1) A kernel driver may not export its data to sysfs. + +This is most common with third party drivers from outside the +kernel tree. These drivers will not end up having their device nodes +created. Use the +/etc/sysconfig/createfiles configuration file to +manually create the devices. Consult the +devices.txt file inside the kernel documentation +or the documentation for that driver to find the proper major/minor +numbers. + +2) A non-hardware device is required. This is most common with +the Advanced Linux Sound Architecture (ALSA) project's Open Sound +System (OSS) compatibility module. These types of devices can be +handled in one of two ways: + + + +Adding the module names to +/etc/sysconfig/modules +Using an +install line in +/etc/modprobe.conf. This tells the +modprobe command when loading this module, +also load this other module, at the same time.

Some begin with a +K, the others begin with an +S, and all of them have two numbers following the +initial letter. The K means to stop (kill) a service and the S means +to start a service. The numbers determine the order in which the +scripts are run, from 00 to 99—the lower the number the earlier it +gets executed. When init switches to another run-level, the +appropriate services get killed and others get started. + +The real scripts are in /etc/rc.d/init.d.

The principle reason is to install a Linux system straight +from the source code. A question many people raise is, why go +through all the hassle of manually building a Linux system from +scratch when you can just download and install an existing +one? That is a good question and is the impetus for this +section of the book. + +One important reason for LFS's existence is to help people learn +how a Linux system works from the inside out. Building an LFS system +helps demonstrate what makes Linux tick, and how things work together +and depend on each other. One of the best things that this learning +experience provides is the ability to customize Linux to your own +tastes and needs. + +A key benefit of LFS is that it allows users to have more +control over the system without relying on someone else's Linux +implementation. With LFS, you are in the +driver's seat and dictate every aspect of the system, such as the +directory layout and bootscript setup. You also dictate where, why, +and how programs are installed. + +Another benefit of LFS is the ability to create a very compact +Linux system. When installing a regular distribution, one is often +forced to install several programs which are probably never used. +These programs waste precious disk space, or worse, CPU cycles. It is +not difficult to build an LFS system of less than 100 megabytes (MB), +which is substantially smaller compared to most existing setups. Does +this still sound like a lot of space? A few of us have been working on +creating a very small embedded LFS system. We successfully built a +system that was specialized to run the Apache web server with +approximately 8MB of disk space used. Further stripping could bring +this down to 5 MB or less. Try that with a regular distribution! +This is only one of the many benefits of designing your own Linux +implementation. + +We could compare Linux distributions to a hamburger purchased at +a fast-food restaurant—you have no idea what might be in what +you are eating. LFS, on the other hand, does not give you a hamburger. +Rather, LFS provides the recipe to make the exact hamburger desired. +This allows users to review the recipe, omit unwanted ingredients, and +add your own ingredients to enhance the flavor of the burger. +When you are satisfied with the recipe, move on to preparing it. It +can be made to exact specifications—broil it, bake it, deep-fry +it, or barbecue it. + +Another analogy that we can use is that of comparing LFS with a +finished house. LFS provides the skeletal plan of a house, but it is up +to you to build it. LFS maintains the freedom to adjust plans +throughout the process, customizing it to the user's needs and +preferences. + +An additional advantage of a custom built Linux system is +security. By compiling the entire system from source code, you are +empowered to audit everything and apply all the security patches +desired. It is no longer necessary to wait for somebody else to +compile binary packages that fix a security hole. Unless you +examine the patch and implement it yourself, you have no guarantee +that the new binary package was built correctly and adequately fixes +the problem. + +The goal of Linux From Scratch is to build a complete and usable +foundation-level system. Readers who do not wish to build their own +Linux system from scratch may not benefit from the information in this +book. If you only want to know what happens while the computer boots, +we recommend the From Power Up To Bash Prompt HOWTO +located at or on +The Linux Documentation Project's (TLDP) website at . +The HOWTO builds a system which is similar to that of this book, +but it focuses strictly on creating a system capable of booting to a +BASH prompt. Consider your objective. If you wish to build a Linux +system while learning along the way, then this book is your best +choice. + +There are too many good reasons to build your own LFS system to +list them all here.

After working with it for awhile, I +discovered issues I definitely would have liked to see improved upon. +For example, I didn't like the arrangement of the bootscripts or the way +programs were configured by default. I tried a number of alternate +distributions to address these issues, yet each had its pros and cons. +Finally, I realized that if I wanted full satisfaction from my Linux +system, I would have to build my own from scratch. + +What does this mean? I resolved not to use pre-compiled packages +of any kind, nor CD-ROMs or boot disks that would install basic +utilities. I would use my current Linux system to develop my own +customized system. This perfect Linux system would then +have the strengths of various systems without their associated +weaknesses. In the beginning, the idea was rather daunting, but I +remained committed to the idea that a system could be built that would +conform to my needs and desires rather than to a standard that just +did not fit what I was looking for. + +After sorting through issues such as circular dependencies and +compile-time errors, I created a custom-built Linux system that was +fully operational and suitable to individual needs. This process also +allowed me to create compact and streamlined Linux systems which are +faster and take up less space than traditional operating systems. I +called this system a Linux From Scratch system, or an LFS system for +short. + +As I shared my goals and experiences with other members of the +Linux community, it became apparent that there was sustained interest +in the ideas set forth in my Linux adventures. Such custom-built LFS +systems not only to meet user specifications and requirements, but +also serve as an ideal learning opportunity for programmers and system +administrators to enhance their Linux skills. Out of this broadened +interest, the Linux From Scratch Project was born. + +This Linux From Scratch book provides +readers with the background and instruction to design and build custom +Linux systems. This book highlights the Linux from Scratch project and +the benefits of using this system. Users can dictate all aspects of +their system, including directory layout, script setup, and security. +The resulting system will be compiled straight from the source code, +and the user will be able to specify where, why, and how programs are +installed. This book allows readers to fully customize Linux systems +to their own needs and allows users more control over their +system. + +I hope you will have a great time working on your own LFS +system, and enjoy the numerous benefits of having a system that is +truly your own. + + + +-- +Gerard Beekmans +gerard@linuxfromscratch.org + diff --git a/prologue/organization.xml b/prologue/organization.xml index 70d8572e4..f701fc388 100644 --- a/prologue/organization.xml +++ b/prologue/organization.xml @@ -7,6 +7,34 @@ Structure -See testing +This book is divided into the following parts. + + +Part I - Introduction + +Part I explains a few important notes on how to proceed with the +LFS installation.
