Hi George:
Following is the procedure I used for building little endian and big endian
tool chain for strong ARM.
Because I did not have a simulator for strong ARM, the complier is not
tested yet. I believe it will take a while to build a simulator. In order
to share the experience, I post the procedure to the arm linux-list per your
requirement. In building the toolchain, I also got very helpful information
from Nick Clifton [[EMAIL PROTECTED]], Philip Blundell
[[EMAIL PROTECTED]], and Erik Mouw [[EMAIL PROTECTED] If there
is any error in the procedure, please let me know.
1. Little endian
1.1 Code base

1.2 untar all the *.tar.gz files, apply the patches to the corresponding
sourcs tree like
your-dir/arm-build-src/binutils-2.9.5.0.29
your-dir/arm-build-src/gcc-2.95.2
your-dir/arm-build-src/glibc-2.1.3

1.5 %cd you-dir/armbuild/binutils-2.9.5.0.29
%your-dir/arm-build-src/binutils-2.9.5.0.29/configure
--target=arm-linux --prefix=/usr/local/arm
%make
%make install

Select the ARM platform (I used SA110)
%make dep
1.7 Copy Linux header files
%cd /usr/local/arm/arm-linux
%mkdir include
%cd include
%copy -dR you-dir/linux-2.2.12/linxu/include/asm-arm asm

arm-linux --build=i686-pc-linux-gnu
--prefix=/usr/local/arm/arm-linux --enable-add-ons
%make
%make install
1.10 Modify gcc-2.95.2/gcc/config/arm/t-linux (From George France)
Use your favorite editor to modify the file 't-linux' to remove
'-Dinhibit_libc -D__gthr_posix_h' to the line that starts
'TARGET_LIBGCC2_CFLAGS = -fomit-frame-pointer -fPIC. This is
change the
TARGET_LIBGCC2_CFLAGS = -fomit-frame-pointer -fPIC -Dinhibit_libc
-D__gthr_posix_h
To
TARGET_LIBGCC2_CFLAGS = -fomit-frame-pointer - fPIC
1.11 Modify basic.c file in /your-dir/arm-build-src/gcc-2.95.2/libchill
(From George France)
inserting after line 40 a new line "#define PATH_MAX 4095".
1.12 Re-build c and c++
%cd your-dir/armbuild/gcc-2.9.2
%your-dir/arm-build-src/gcc-2.95.2/configure --target=arm-linux
--prefix=/usr/local/arm
%make LANGUAGES="c c++"
%make install
1.13 Compile Linux kernel
Modify the Makefile to do
CROSS_COMPILE=arm-linux-
modify /linux/-2.2.12/arch/arm/vmlinux-armo.lds and vmlinux-armv.lds
change elf32-arm to elf32-littlearm
