binutils-2.15.tar.bz2
gcc-3.4.3.tar.bz2
newlib-1.13.0.tar.gz

- build binutils

mkdir build
cd build
../binutils-2.15/configure --target=arm-elf --prefix=`pwd`/../install
make
make install
cd ..

- add the fresh binutils to the FRONT of the path

export PATH=`pwd`/install/bin:$PATH


- Copy libgloss & newlib into GCC source directory

- create eCos header files

ecosconfig new eb40a default
ecosconfig add posix
ecosconfig add fileio
set:

cdl_option CYGPKG_LIBC_I18N_NEWLIB_CTYPE {
    user_value 1
};

ecosconfig tree
make headers

- TRICK!!!! WHY??? NB! Copy the eCos header files into the GCC build directory. NB!
 
mkdir -p arm-elf/newlib/targ-include
# timestamp to avoid newlib overwriting our files
mkdir -p arm-elf/newlib/stmp-targ-include
cp -r ../ecos/install/include/* arm-elf/newlib/targ-include/
mkdir -p arm-elf/thumb/newlib/targ-include
# timestamp to avoid newlib overwriting our files
mkdir -p arm-elf/thumb/newlib/stmp-targ-include
cp -r ../ecos/install/include/* arm-elf/thumb/newlib/targ-include/


- Configure GCC:

../gcc-3.4.3/configure --target=arm-elf   --prefix=`pwd`/../install --enable-languages=c,c++   --with-gnu-as --with-gnu-ld --with-newlib --enable-threads=posix --without-headers --enable-libstdcxx-allocator=malloc --enable-cstdio=stdio --disable-shared

FIX? remove the "--without-headers" option?

- Kludges to get compilation going again when it fails:
  - compilation fails a couple of times because the eCos header files have been
    deleted. Copy the eCos header files again, and type make 
  - When compilation fails, modify arm-elf/thumb/libstdc++-v3/config.h & 
    arm-elf/libstdc++-v3/config.h
    #undef HAVE_STRTOF
  - _NEWLIB_VERSION have not been defined by the eCos include files and hence
    testsuite_hooks.cc fails. Modify testsuite_hooks.cc and continue.
