[Samsung Galaxy Star] Hicham03:
I successfully initialized CM12.1 git, setted up device folder, but when I type "brunch higgs2g", I got a lot of errors:

hicham03@hp-compaq-6000-pro-sff-pc:~/Desktop/cm12.1$ brunch higgs2g
including vendor/cm/vendorsetup.sh

Trying dependencies-only mode on a non-existing device tree?

My PC specs are: HP Compaq 6000 Pro SFF (an old PC!), Intel Pentium Dual-Core 2.8GHz, 2GB RAM, Ubuntu 15.10 i686 OS (I can update to 64bit, but I have only 2GB RAM)

Anyone knows what I am doing wrong here?
