SYNOPSIS: How to build LFS for different sub-architectures.

PRIMARY URI:
http://www.comlore.com/i386-pc-linux-gnu

DESCRIPTION:
Additive instructions on how to cross-build a LFS-system for different x86 sub-architectures.

PREREQUISITES:
The command-replacements are applicable for LFS 6.1+SVN20051009.  Similar changes will probably work 
fine on other versions of the book; however your mileage may vary since the resources to 
build a Linux system are under constant revision and replacement.  You should probably have 
either completed a run through the book already or at least read the procedures before you 
start.

Note: There is a nicely formatted pdf and MS *.doc file available at the webpage listed above.  
Please forgive my horrible web design aesthetics and meaningless babble on that webpage, 
but the hint is available there so go take a peek!

HINT:
1.      CROSSCOMPILING-X86

This hint is originally written by Nicholas Dille <webmaster at rakshas.de>.
Later it was updated and maintained by Daniel Baumann.
Now maintenance is done by Theodore Bullock <tbullock at Canada.com>

1.1.    INTRODUCTION

The GNU Compiler Collection (GCC) can build binaries for multiple platforms.

It is not especially complicated to cross-compile between different sub-architectures, for 
example, to build i386 binary executables on an i686 computer.  On the other hand, to cross-
compile between totally different architectures, for example, building PowerPC binary 
executables on an i386 machine, an entirely different tool-chain is required and is beyond the 
scope of this hint.

Ideally, all packages should get their information about the target from autoconf configuration 
parameters and compiler flags.  Unfortunately this is not the reality.  Some packages use 
different flags and a few packages, (notably GCC and Glibc), need other trickery to fake their 
auto-detection in place of flags.

Additionally, if you are trying to build LFS on a very old 386 then there is an extra trick to 
completing the procedure.

This hint does not cover building LFS onto i286 or older machines as these processors lack 
some critical functionality to handle modern memory management.  For information on that 
topic search the internet for embedded Linux solutions.

1.2.    About $CHOST

As with $LFS, we will use the variable $CHOST to specify the type of computer we are 
compiling on. To cross-compile you have to replace $CHOST with a value matching for your 
target computer.

If your target machine is currently running a flavour of Linux then you can get the correct 
value from your target computer with

        # uname -m

If you have not already a running Linux system on the target machine, use the corresponding 
value from this list instead:

        Intel 386:                                      i386
        Intel 486:                                      i486
        Intel Pentium 1 and MMX:                        i586
        Intel Pentium Pro, 2, 3, 4 and M:               i686
        AMD K5, K6-1, K6-2 and K6-3:                    i586
        AMD Athlon 1, 2, 3, 4 and 5:                    i686
        IDT WinChip-C6, WinChip2:                       i486
        VIA C3:                                         i486

The rest of the hint assumes you have set $CHOST as an environment variable, for example

        # export CHOST="i386-pc-linux-gnu"

1.3.    About $CFLAGS and $CXXFLAGS

$CFLAGS and $CXXFLAGS are environment variable that pass user flags to GCC and G++ 
respectively.  Often, they are used to set the optimization level (-On, where n is an integer). 
For details about optimization, please refer to the optimization hint. Here, we force GCC to 
compile for the desired sub-architecture using -march.

Choose from this list:

        Intel 386                       i386
        Intel 486                       i486
        Intel Pentium 1:                pentium
        Intel Pentium MMX:              pentium-mmx
        Intel Pentium Pro:              pentiumpro
        Intel Pentium 2:                pentium2
        Intel Pentium 3:                pentium3
        Intel Pentium 4 and M:          pentium4

        AMD K5:                         pentium
        AMD K6-1:                       k6
        AMD K6-2:                       k6-2
        AMD K6-3:                       k6-3
        AMD Athlon 1 (Classic):         athlon
        AMD Athlon 2 (Thunderbird):     athlon-tbird
        AMD Athlon 3 (XP):              athlon-xp
        AMD Athlon 4 (Palomino):        athlon-4
        AMD Athlon 5 (MP):              athlon-mp

        IDT WinChip-C6:                 winchip-c6
        IDT WinChip-2:                  winchip2
        VIA C3:                         c3

The rest of the hint assumes you have set $CFLAGS and $CXXFLAGS as environment 
variables, for example:

        export CFLAGS="-march=i386"
        export CXXFLAGS="-march=i386"

1.3.1.  ATTENTION REGARDING OPTIMIZATION

If you use optimization, in the majority of cases the binaries can only be used on the target 
machine. This means, sharing self-generated binary-packages between different hosts is not 
possible.

2.      LFS-Book

The following sections are ordered as a skeleton of the information in the LFS book
2.1.    Chapter 4: Final Preparations

2.1.1.  About $LFS

Add:
export CHOST="<value>"
export CFLAGS="<value>"
export CXXFLAGS="<value>"

Note:   Please replace <value> with the proper strings as was discussed earlier



2.2.    Chapter 5: Constructing a Temporary System

2.2.1.  Binutils-2.16.1

Change:

../binutils-2.16.1/configure --prefix=/tools --disable-nls

To:
../binutils-2.16.1/configure --host="$CHOST" --target="$CHOST" \
--prefix=/tools --disable-nls

2.2.2.  GCC-4.0.2 - Pass 1

Change:
../gcc-4.0.2/configure --prefix=/tools \
--libexecdir=/tools/lib --with-local-prefix=/tools \
--disable-nls --enable-shared --enable-languages=c

To:
../gcc-4.0.2/configure --host="$CHOST" --target="$CHOST" \
--prefix=/tools --libexecdir=/tools/lib \
--with-local-prefix=/tools --disable-nls \
--enable-shared --enable-languages=c

And then, change:
make bootstrap

To:
make BOOT_CFLAGS="$CFLAGS" bootstrap

2.2.3.  Linux-Libc-Headers-2.6.12.0

No changes - we are just copying the header files here.

2.2.4.  Glibc-2.3.5

Ok, this one is a bit trickier and what you put here can have some important ramifications 
later.  If your target machine is a 486 or higher you should follow the (>=486) instructions 
otherwise you should follow the (386) instructions.  The reason for this is that the basic 386 
instruction set is missing one of the atomic instructions important to multi-threading with the 
NPTL threading system.  Instead you will use the linuxthreads library which does not require 
this instruction.

Change:

../glibc-2.3.5/configure --prefix=/tools \
--disable-profile --enable-add-ons \
--enable-kernel=2.6.0 --with-binutils=/tools/bin \
--without-gd --with-headers=/tools/include \
--without-selinux

(>=486)To:
../glibc-2.3.5/configure --host="$CHOST" --target="$CHOST" \
--prefix=/tools --disable-profile --enable-kernel=2.6.0 \
--with-binutils=/tools/bin --without-gd \
--with-headers=/tools/include --without-selinux

(386)To:
../glibc-2.3.5/configure --host="$CHOST" --target="$CHOST" \
--prefix=/tools --disable-profile --enable-add-ons=linuxthreads \
--with-tls --without-__thread --enable-kernel=2.6.0 \
--with-binutils=/tools/bin --without-gd \
--with-headers=/tools/include --without-selinux

Since glibc needs to be compiled with some level of optimization we need to add an 
optimization flag to $CFLAGS.  Please change this to suit your needs.


And then change:
make

To:
make CFLAGS="$CFLAGS -O2"

And then change:
make install

To:
make CFLAGS="$CFLAGS -O2" cross-compiling=no install

2.2.5.  Adjusting the tool-chain

--with-tclinclude=$TCLPATH

To:

--with-tclinclude=$TCLPATH

2.2.8.  DejaGnu-1.4.4

--enable-languages=c,c++ --disable-libstdcxx-pch

To:
../gcc-4.0.2/configure --host="$CHOST" --target="$CHOST" \
--prefix=/tools --libexecdir=/tools/lib \
--with-local-prefix=/tools --enable-clocale=gnu \
--enable-shared --enable-threads=posix \
--enable-__cxa_atexit --enable-languages=c,c++ \
--disable-libstdcxx-pch

And then change:
make

To:
make BOOT_CFLAGS="$CFLAGS" BOOT_CXXFLAGS="$CXXFLAGS"

2.2.10. Binutils-2.16.1 - Pass 2

Change:
../binutils-2.16.1/configure --prefix=/tools \
--enable-shared --with-lib-path=/tools/lib \
--disable-nls

To:
../binutils-2.16.1/configure --host="$CHOST" --target="$CHOST" \
--prefix=/tools --enable-shared --with-lib-path=/tools/lib \

2.3.    Chapter 6: Installing Basic System Software

2.3.1.  Entering the chroot environment

After:
chroot "$LFS" /tools/bin/env -i \
HOME=/root TERM="$TERM" PS1='\u:\w\$ ' \
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/tools/bin \
/tools/bin/bash --login +h

Add:
export CHOST="i386-pc-linux-gnu" &&
export CFLAGS="-march=i386" &&
export CXXFLAGS="-march=i386"

Note:   Please replace i386 with the proper strings according to the introduction.

2.3.2.  Linux-Libc-Headers-2.6.12.0

No changes - we are just copying the header files here.

2.3.3.  Man-pages-2.08

No changes - we are just copying the man-pages here.

2.3.4.  Glibc-2.3.5

Ok, this one is a bit trickier and what you put here can have some important ramifications 
later.  If your target machine is a 486 or higher you should follow the (>=486) instructions 
otherwise you should follow the (386) instructions.  The reason for this is that the basic 386 
instruction set is missing one of the atomic instructions important to multi-threading with the 
NPTL threading system.  Instead you will use the linuxthreads library which does not require 
this instruction.

Change:

../glibc-2.3.5/configure --prefix=/usr \
--disable-profile --enable-add-ons \
--enable-kernel=2.6.0 --libexecdir=/usr/lib/glibc

(>=486)To:
../glibc-2.3.5/configure --host="$CHOST" --target="$CHOST" \
--prefix=/usr --disable-profile --enable-add-ons=nptl \
--with-tls --with-__thread --enable-kernel=2.6.0 \
--libexecdir=/usr/lib/glibc

(386)To:
../glibc-2.3.5/configure --host="$CHOST" --target="$CHOST" \
--prefix=/usr --disable-profile --enable-add-ons=linuxthreads \
--with-tls --without-__thread --enable-kernel=2.6.0 \
--libexecdir=/usr/lib/glibc

Since glibc needs to be compiled with optimization, we have to modify our $CFLAGS 
environment variable.  Change this to suite your own needs.

And then change:
make

To:
make CFLAGS="$CFLAGS -O2"

And then change:
make install

To:
make CFLAGS="$CFLAGS -O2" cross-compiling=no install

Note:   This does not affect cross compiling for sub-architectures (it prevents Glibc to look for a 
cross compiler and uses the native one).

2.3.5.  Re-adjusting the toolchain

No changes - we are using preconfigured code.

2.3.6.  Binutils-2.16.1

Change:

make

To:
make BOOT_CFLAGS="$CFLAGS" BOOT_CXXFLAGS="$CXXFLAGS"

echo "export CFLAGS=\"$(echo $CFLAGS)\"" >> /etc/profile
echo "export CXXFLAGS=\"$(echo $CXXFLAGS)\"" >> /etc/profile
