Introduction

We'll build a GCC 9.3.0 targeting bare metal ARM.

Create directories

cd $HOME
mkdir -p src obj/{binutils-build,gcc-build,gdb-build,newlib-build}

Get GCC, GDB and binutils

curl https://ftp.gnu.org/gnu/binutils/binutils-2.34.tar.gz | tar -C $HOME/src -xf -
curl https://ftp.gnu.org/gnu/gdb/gdb-9.1.tar.gz | tar -C $HOME/src -xf -
curl https://ftp.gnu.org/gnu/gcc/gcc-9.3.0/gcc-9.3.0.tar.gz | tar -C $HOME/src -xf -
curl ftp://sourceware.org/pub/newlib/newlib-3.3.0.tar.gz | tar -C $HOME/src -xf -

Download prerequisites

cd $HOME/src/gcc-9.3.0
./contrib/download_prerequisites

Build and install binutils

make -j8 && make install

Build and install bare metal gcc

cd $HOME/obj/gcc-build
../../src/gcc-9.3.0/configure --prefix $HOME/xgcc --bindir $HOME/bin --target arm-none-eabi --enable-multilib --enable-languages=c --without-headers
make -j8 all-gcc && make install-gcc

Build and install newlib

cd $HOME/obj/newlib-build
../../src/newlib-3.3.0/configure --prefix $HOME/xgcc --bindir $HOME/bin --target arm-none-eabi --enable-multilib
make -j8 all && make install

Build and install newlib gcc

rm -rf $HOME/obj/gcc-build && mkdir -p $HOME/obj/gcc-build
cd $HOME/obj/gcc-build
../../src/gcc-9.3.0/configure --prefix $HOME/xgcc --bindir $HOME/bin --target arm-none-eabi --enable-multilib --enable-languages=c --with-newlib
make -j8 all && make install
