Ciao!
How are you?
Since make is often is not good to use, does make image uses the -j9 flag? Since the image builder is safe, but I do not know it uses this flag...
Have a nice day,
Patrik
People usually build/compile code for LEDE on a x86 64bits virtual machine on a PC or Mac with Debian or if not possible Ubuntu. You can see my notes about if you like: https://gist.github.com/braian87b/4a9048dcc2e2fd244f7d44b8896b7ccc
AFAIK -j9 only says that it allows to spawn 9 build threads, and this only fails on limited CPU/RAM devices.
