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

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@"
