Introduction

We'll build a GCC 9.3.0 targeting m68k (Sega Genesis).

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 -
