my mac as 32 GB of memory and a dual quad core...
the linux box as 8GB and a signle quad...
'low system ressource' is  _not_ the problem here.

Yes, but the generated daily build would be less usefull that way and

The mac version did not finished it died afeter 20+minutes

note : if for that/these source -O is not necessary or useful then you
can tell the build to do a NOOPT compile. see sd/Library_sd.mk for an
