How many GB of ram do you have? How many processes are you using for compilation? Can you either increase the former or decrease the latter (with -j).

I have 4Gb and compiled without any -j flags.
I see your point, will try to decrease j. Thanks.

Cheers,
Boris

Yeah, with 4GB you should use -j1, I am afraid.

Thank you Giulio,
