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-2.17.tar.gz
    gcc-4.2.1.tar.gz
    glibc-2.3.6.tar.gz
    glibc-linuxthreads-2.3.6.tar.gz


2. binutils-2.17

   tar xvzf binutils-2.17.tar.gz
   cd binutils-2.17
   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-4.2.1

   tar xvjf gcc-4.2.1.tar.bz2
   cd gcc-4.2.1

   cp $(ATTACHED t-linux file) gcc/config/arm/
   vi gcc/config/arm/linux-elf.h
     -- remove line that defines LIBGCC_SPEC
   vi gcc/config/arm/lib1funcs.asm
     -- change line 999 which are:

        mov     r0, #SIGFPE
        bl      SYM(raise) __PLT__

     to be:

        bl      SYM (__div0) __PLT__
        mov     r0, #0                  @ About as wrong as it could be.


   mkdir arm-linux
   cd arm-linux
   ../configure --target=arm-linux --disable-shared --disable-threads \
    --disable-libmudflap --disable-libssp \
    --with-headers=linux-2.6.x/include \
    --prefix=/usr/local --with-gnu-as --with-gnu-ld --enable-multilib \

      - comment out line 5 "weak_alias (listen, __listen)"
   vi sysdeps/unix/sysv/linux/setsockopt.S
      - comment out line 5 "weak_alias (setsockopt, __setsockopt)"
   vi sysdeps/arm/dl-machine.h
      - line 360, remove "static" before function fix_bad_pc24
