Build error for make wp_77xx

Hi All,

I followed the Getting start guide. At the stage, "prepare your mangOH board for your development "
when I give the command make wp_76xx , i get the following errors . DO I miss something here ?

Makefile:86: ==== OCTAVE_ROOT not defined ====
Not building LEGATO due to $LEGATO == 0
make: /home/mangoh/legato_framework/legato/bin/findtoolchain: Command not found
make: /home/mangoh/legato_framework/legato/bin/findtoolchain: Command not found

NOTE: When using leaf, these TOOLCHAIN_X variables don’t need to be passed to mksys.

TOOLCHAIN_DIR=
TOOLCHAIN_PREFIX=
OCTAVE=
mksys -t wp77xx --cflags=-O2 --object-dir=build/red_wp77xx --output-dir=build/update_files red.sdef
/bin/sh: 1: mksys: not found
Makefile:115: recipe for target ‘red_wp77xx’ failed
make: *** [red_wp77xx] Error 127

seems you need to first go to the legato framework, and type “. ./configlegatoenv”
e.g.
