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

# to do it.

# Assemble startup files.
