x86_64-pc-linux-gnu-g++: fatal error: Killed signal terminated program cc1plus compilation terminated.
Most likely lack of resources on your machine.
fatal error: Killed signal terminated program cc1plus Yes, the compiler was most likely killed by the Out-of-Memory (OOM) killer, there's likely a mention of it near the end of `dmesg` output. I don't see your `emerge --info` to know what kind of setup you have, but try a lower MAKEOPTS=-jN value (cc1plus can sometime use up to 2GB ram per process), adding swap space could help too, and don't use tmpfs for PORTAGE_TMPDIR (just in case you were).
Yes, swapon seems to have fixed this. I only have 16Gb RAM on this machine, and beasts like Firefox, Webkit or Chromium compile just fine...
