HOWTO build arm-linux toolchain for ARM/XSCALE
----------------------------------------------
These instructions document how to build an arm-linux tool chain
that contains both little-endian and big-endian target libraries.
1. Packages used:
binutils-2.16.tar.gz
gcc-3.4.4.tar.gz
glibc-2.3.3.tar.gz
glibc-linuxthreads-2.3.3.tar.gz
2. binutils-2.16
tar xvzf binutils-2.16.tar.gz
cd binutils-2.16
mkdir arm-linux
cd arm-linux
../configure --target=arm-linux --with-lib-path=/usr/local/arm-linux/lib:/usr/local/arm-linux/lib/be:/usr/local/arm-linux/lib/soft-float:/usr/local/arm-linux/lib/be/soft-float
make
make install
chmod 777 /usr/local/arm-linux
3. gcc-3.4.4
tar xvzf gcc-3.4.4.tar.gz
cd gcc-3.4.4
cp $(ATTACHED t-linux file) gcc/config/arm/
vi gcc/config/arm/linux-elf.h
-- remove line that defines LIBGCC_SPEC
mkdir arm-linux
cd arm-linux
../configure --target=arm-linux --disable-shared --disable-threads \
--prefix=/usr/local --with-headers=linux-2.4.x/include \
--with-gnu-as --with-gnu-ld --enable-multilib --enable-languages=c

make install
4. glibc-2.3.3 (big-endian)
tar xvzf glibc-2.3.3.tar.gz
cd glibc-2.3.3
tar xvzf glibc-linuxthreads-2.3.3.tar.gz
rm -rf nptl
vi sysdeps/unix/sysv/linux/arm/ioperm.c
- change "BUS_ISA" to be "CTL_BUS_ISA" lines 103 and 104
vi config.make.in
- change "slibdir = @...@" to "slibdir = @libdir@"
vi Makeconfig
- change all occurrances of "O2" to "O"
- remove any occurrances of -lgcc_eh
vi configure
- change all occurrances of "O2" to "O"
