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-2.14.tar.gz
    gcc-3.3.2.tar.gz
    glibc-2.2.5.tar.gz
    glibc-linuxthreads-2.2.5.tar.gz


2. binutils-2.14

   tar xvzf binutils-2.14.tar.gz
   cd binutils-2.14
   mkdir arm-linux
   cd arm-linux
   ../configure --target=arm-linux

   vi ld/earmelf_linux.c
     - add a new serach_dir line for every current serach_dir line in file
search_dir(/"/usr/local/arm-linux/lib/be/");/n/

   make
   make install
   chmod 777 /usr/local/arm-linux


3. gcc-3.3.2

   tar xvzf gcc-3.3.2.tar.gz
   cd gcc-3.3.2
   cp $(attached t-linux file) gcc/config/arm/
   mkdir arm-linux
   cd arm-linux
   ../configure --target=arm-linux --disable-shared --disable-threads /
--with-headers=linux-2.4.x/include /
--with-gnu-as --with-gnu-ld --enable-multilib --enable-languages=c
   make install


4. glibc-2.2.5 (big-endian)

   tar xvzf glibc-2.2.5.tar.gz
   cd glibc-2.2.5
   tar xvzf glibc-linuxthreads-2.2.5.tar.gz

   perl -pi -e 's/i386/arm*)/n/tlibc_cv_gcc_unwind_find_fde=yes/n/tarch_minimum_kernel=2.0.10/n/t;;/n   i386/' sysdeps/unix/sysv/linux/configure
   perl -pi -e 's/weak_alias /(__old_sys_nerr///// $&/' sysdeps/unix/sysv/linux/arm/errlist.c
   vi linuxthreads/sysdeps/pthread/pthread.h
      - change line 163, "__thread" -> "__thr"
      - change line 591, "__thread" -> "__thr"
   vi linuxthreads/internals.h
      - change line 555, "__thread" -> "__thr"
   vi linuxthreads/sysdeps/unix/sysv/linux/bits/sigthread.h
      - change line 36, "__thread" -> "__thr"
   vi stdio-common/sprintf.c
      - line 30, change to "sprintf(char *s, const char *format, ...)"
   vi stdio-common/sscanf.c
      - line 30, change to "sscanf(const char *s, const char *format, ...)"
   vi sysdeps/unix/sysv/linux/arm/sysdep.h
      - line 134, remove "a1" from clobber list
   vi sysdeps/arm/dl-machine.h
      - add '/n/' to end of all macro asm lines (there is a _lot_ of them)

   vi config.make.in
      - change "slibdir=@...@" to "slibdir=@libdir@"

   mkdir arm-linux
   cd arm-linux
   cc="arm-linux-gcc -mbig-endian -finline-limit=10000" /
   as="arm-linux-as -mbig-endian" /
   ld="arm-linux-ld -eb" /
   ../configure --host=arm-linux --build=i686-pc-linux-gnu /
--with-headers=linux-2.4.x/include /
--enable-add-ons --enable-shared --prefix=/usr/local/arm-linux /
--libdir=/usr/local/arm-linux/lib/be
   make
   make install


5. glibc-2.2.5 (little-endian)

   tar xvzf glibc-2.2.5.tar.gz
   cd glibc-2.2.5
   tar xvzf glibc-linuxthreads-2.2.5.tar.gz

   [ apply same fixes as above ]

   mkdir arm-linux
   cd arm-linux
   cc="arm-linux-gcc -finline-limit=10000" /
   as="arm-linux-as" /
   ld="arm-linux-ld" /
   ../configure --host=arm-linux --build=i686-pc-linux-gnu /
--with-headers=linux-2.4.x/include /
--enable-add-ons --enable-shared --prefix=/usr/local/arm-linux
   make
   make install


6. gcc-3.3.2 (c++, etc)

   tar xvzf gcc-3.3.2.tar.gz
   cd gcc-3.3.2

   cp $(attached t-linux file) gcc/config/arm/
   vi gcc/config/arm/t-linux 
      - remove all "-dinhibit_libc" occruances

   mkdir arm-linux
   cd arm-linux
   ../configure --target=arm-linux --disable-shared /
--with-headers=linux-2.4.x/include /
--with-gnu-as --with-gnu-ld --enable-multilib
   perl -pi -e 's/int namelen/unsigned int namelen/' ../libjava/java/net/natinetaddress.cc
   make
   make install


7. cd /
   tar cvzf /tmp/arm-linux-tools-xxxxxxxx.tar.gz /usr/local/arm-linux /
/usr/local/lib/gcc-lib/arm-linux /usr/local/include/c++/3.3.2 /
/usr/local/bin/arm-linux-* /usr/local/bin/genext2fs
