Setup env vars

Terminal window
export PREFIX="$HOME/opt/cross"
export TARGET=sh4eb-elf
export PATH="$PREFIX/bin:$PATH"

Install and build BinUtils

Install-binutils.sh

Terminal window
version=2.37


prefix=$PREFIX/sh4eb-nofpu-elf


jobs=`nproc 2> /dev/null || echo 1`


tar=binutils-${version}.tar.gz
url=ftp://ftp.gnu.org/gnu/binutils/$tar
test -f $tar || curl -L $url -o $tar
tar -zxf $tar


mkdir binutils-${version}-build
cd binutils-${version}-build
../binutils-${version}/configure --target=sh4eb-nofpu-elf --prefix=$prefix \
          --disable-nls --disable-shared --disable-multilib
make -j $jobs
make install
cd ..

And GCC Install-gcc.sh

Terminal window
version=11.2.0


prefix=$PREFIX/sh4eb-nofpu-elf


jobs=`nproc 2> /dev/null || echo 1`


tar=gcc-${version}.tar.gz
url=ftp://ftp.gnu.org/gnu/gcc/gcc-${version}/$tar
test -f $tar || curl -L $url -o $tar
tar -zxf $tar


cd gcc-${version}
./contrib/download_prerequisites
cd ..


mkdir gcc-${version}-build
cd gcc-${version}-build
../gcc-${version}/configure --target=sh4eb-nofpu-elf --prefix=$prefix \
          --enable-languages=c,c++ \
            --with-newlib --without-headers --disable-hosted-libstdcxx \
              --disable-nls --disable-shared --enable-libssp --enable-lto --with-multilib-list=m4-nofpu
make -j $jobs all-gcc all-target-libgcc
make install-gcc install-target-libgcc
cd ..

Now NewLib Install-newlib.sh

Terminal window
version=1.14.0


prefix=$PREFIX/../src/hollyhock-2/sdk/newlib


jobs=`nproc 2> /dev/null || echo 1`




wget ftp://sourceware.org/pub/newlib/newlib-${version}.tar.gz


tar xzfv newlib-${version}.tar.gz


mkdir newlib-${version}-build
cd newlib-${version}-build


export TARGET_BINS="sh4eb-nofpu-elf"


../newlib-${version}/configure --target="sh-elf" --prefix=$PREFIX


# Fix CC
grep -rli 'sh-elf-' * | xargs -i@ sed -i 's/sh-elf-/sh4eb-nofpu-elf-/g' @
grep -rli 'sh4eb-nofpu-elf-cc' * | xargs -i@ sed -i 's/sh4eb-nofpu-elf-cc/sh4eb-nofpu-elf-gcc/g' @


make -j $jobs
make install
cd ..

Rebuild Full GCC Full-gcc.sh

Terminal window
version=11.2.0
prefix=$PREFIX/sh4eb-nofpu-elf-full


mkdir gcc-${version}-build-full
cd gcc-${version}-build-full


../gcc-${version}/configure --target=sh4eb-nofpu-elf --prefix=$prefix \
          --enable-languages=c,c++ \
            --with-newlib --without-headers --disable-hosted-libstdcxx \
              --disable-nls --disable-shared --enable-libssp --enable-lto --with-multilib-list=m4-nofpu
