Created attachment 680368 [details] USE for tensorflow I have this in package.use: sci-libs/tensorflow cuda xla
I'm using gentooLTO: https://github.com/InBetweenNames/gentooLTO. gentooLTO uses this workaround for tensorflow: sci-libs/tensorflow *FLAGS-=-flto* # Issue #432 tensorflow-estimator fails with missing symbol __cpu_model
"fatal error: Killed signal terminated program cc1plus" Looks like the compiler was killed by the Out-of-Memory (OOM) killer, you may have a note about this near the end of `dmesg` output. Depending on settings this has potential to happen even with 32GB ram. May want to try a lower MAKEOPTS=-jN value, add a some swap, or if you were using tmpfs for /var/tmp I'd suggest not to (that would fill up ~10GB ram on its own). I would also recommend to test more normal C(XX)FLAGS (e.g. -march=native -O2) when reporting issues rather than GentooLTO's
