To build the tools you will need the sources for the Lattice Mico32 GNU Tools which you can download from the Lattice site.

You will also need the sources for newlib-1.16.0.cvs.20081127 from the RTEMS ftp server and RTEMS specific patches for newlib.

In addition to these sources you will need the following patches:

binutils-2.18-rtems4.10-lm32-20081117.diff
gcc-3.4.4-rtems4.10-lm32-20081209.diff
newlib-1.16.0.cvs.lm32-20081127.diff

The tools can be built for example on Fedora 9, however, the versions automake and autoconf required by rtems-4.10 are not provided here so these have to be installed separately (see RTEMS Wiki for detailed instructions how to load Yum repository configuration information).

yum -y install "*4.10*auto*"

Download the sources and patches listed above and build and install the tools following.

mkdir build-lm32-tools
cd build-lm32-tools/
tar zxf ../tool-sources/mico32_gnutools_src_7.1.tar.gz

Apply patch for binutils

cd src/binutils
patch -p1 < ../../../tool-sources/binutils-2.18-rtems4.10-lm32-20081117.diff
cd ../..

Build and install binutils

mkdir b-binutils
cd b-binutils
../src/binutils/configure --prefix=/opt/rtems-4.10 --target=lm32-rtems4.10 \
        --disable-nls
make -w all
make install (as root)
cd ..

Untar and patch newlib-1.16.0.cvs

tar zxf ../tool-sources/newlib-1.16.0.cvs.20081127.tar.gz
cd newlib-1.16.0
patch -p1 < ../../tool-sources/newlib-1.16.0.cvs.lm32.20081127.diff
patch -p1 < ../../tool-sources/newlib-1.16.0.cvs.20081128-rtems4.10-20081128.diff
cd newlib/libc/machine/lm32/
aclocal -I ../../..
autoconf
automake -a --cygnus Makefile
cd ../../../../..

We need to replace the version of newlib supplied with the Lattice sources with a more recent one and patch the gcc sources.

cd src
rm -rf newlib
cd gcc
ln -s ../../newlib-1.16.0/newlib newlib
patch -p1 < ../../../tool-sources/gcc-3.4.4-rtems4.10-lm32-20081209.diff
cd ../..

Now build and install gcc and newlib

PATH=/opt/rtems-4.10/bin:${PATH}
mkdir b-gcc
cd b-gcc
../src/gcc/configure  --prefix=/opt/rtems-4.10 --bindir=/opt/rtems-4.10/bin \
         --exec_prefix=/opt/rtems-4.10 --includedir=/opt/rtems-4.10/include \
         --libdir=/opt/rtems-4.10/lib --libexecdir=/opt/rtems-4.10/libexec \
         --mandir=/opt/rtems-4.10/man --infodir=/opt/rtems-4.10/info \
         --datadir=/opt/rtems-4.10/share --target=lm32-rtems4.10 \
         --enable-languages=c,c++ --with-newlib --enable-sjlj-exceptions \
         --disable-nls --disable-libstdcxx-patch --with-gnu-as --with-gnu-ld \
         --verbose --with-system-zlib --enable-version-specific-runtime-libs \
         --enable-threads=rtems
make -w all
make install (as root)
