> Hi @jyijyi, Just execute this command: leaf getsrc swi-linux Leaf will pull the entire yocto workspace using repo. You’ll need to setup SSH keys on [gerrit.legato.io](http://gerrit.legato.io) The R11 source will be available with identifier: swi-fx30-catm\_2.0.0 BR, Chris

BTW, I can find the random.h with the toolchain:
