Aram moved page Bare metal RISC-V GCC 9.2.0 cross compiler instructions to Bare metal RISC-V GCC 9.3.0 cross compiler instructions
== Introduction ==
We'll build a GCC 9.23.0 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-2.33.134.tar.gz | tar -C $HOME/src -xf - curl https://ftp.gnu.org/gnu/gdb/gdb-89.31.tar.gz | tar -C $HOME/src -xf - curl https://ftp.gnu.org/gnu/gcc/gcc-9.23.0/gcc-9.23.0.tar.gz | tar -C $HOME/src -xf - curl ftp://sourceware.org/pub/newlib/newlib-3.13.0.tar.gz | tar -C $HOME/src -xf -
