didn’t you can build it before?
You need to install the toolchain and go to the legato framework and set up the environment first:
e.g.
-
sh poky-swi-ext-glibc-x86_64-meta-toolchain-swi-armv7a-neon-toolchain-swi-SWI9X07Y_02.28.03.05.sh
Toolchain will be installed in /opt/swi/
cd legato-19.02.0/
make
. bin/configlegatoenv
