Introduction

We'll build a GCC 9.3.0 targeting PDP-11 (bare metal).

Create directories

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

Get GCC 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/gcc/gcc-9.3.0/gcc-9.3.0.tar.gz | tar -C $HOME/src -xf -

Download prerequisites

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

Build and install binutils

cd $HOME/obj/binutils-build
../../src/binutils-2.34/configure --prefix $HOME/xgcc --bindir $HOME/bin --target pdp11-aout
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 pdp11-aout --enable-languages=c --with-gnu-as --with-gnu-ld --without-headers --disable-libssp
make -j8 && make install
