Download Broadcom hndtools-3.0 toolchain here. This toolchain is to be used on a x86 Linux machine. It’s not for running on MSS itself or Windoze.

Make sure you have a /opt directory, then extract toolchain to /opt (as root user):

# mkdir /opt
# cd /opt
# tar zxf /path/too/hndtools-3.0.tar.gz

Setup the toolchain in your path. If you use bash then type this as normal user:

% echo "export PATH=${PATH}:/opt/brcm/hndtools-mipsel-linux/bin" >>~/.bashrc

Basic crosscompile example.

% ./configure --target=mipsel-linux --host=mipsel-linux --build=i686-pc-linux-gnu
% make
