Introduction
We'll build a GCC 9.2.0 targeting bare metal RISC-V.
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-2.33.1.tar.gz | tar -C $HOME/src -xf - curl https://ftp.gnu.org/gnu/gdb/gdb-8.3.tar.gz | tar -C $HOME/src -xf - curl https://ftp.gnu.org/gnu/gcc/gcc-9.2.0/gcc-9.2.0.tar.gz | tar -C $HOME/src -xf - curl ftp://sourceware.org/pub/newlib/newlib-3.1.0.tar.gz | tar -C $HOME/src -xf -
