rustc exited with signal: 9 That implies something killed the process, most likely the kernel's OOM (Out-of-Memory) killer, so you likely ran out of RAM. Would be mentioned near the end of `dmesg`'s output. I suggest to use lower MAKEOPTS -jN value (like halved to -j6) for this package, rustc can sometime use 2-3.5GB per thread and it adds up. Also ensure not using tmpfs for PORTAGE_TMPDIR). (on side-note, preferably don't use tar for logs) agreed. try to get 2GB per thread for C++ and rust code. so with 18GB it should be no more than -j9 and much much lower than that if you use TMPFS build dir. if you don't use system-bootstrap and system-llvm, tmpfs will use approx 9GB to unpack and build it. that leaves you with 9g to work with. assuming you need at least 1G for runtime, I would not set more than -j4 to build rust with 18G and tmpfs.

I just did a clean reboot and re-emerged rust and it had 17.5GB of memory to build with and it still failed. I know you said to reduce my jobs but I wanted to be sure it was the memory because I've never had that problem in the past when I built it. I've attached the new build.log, I checked it and didn't see any oom errors, but it could be that I just don't know what they look like (I was just skimming through/searching in vim).

I didn't account for my tmpfs... I'll reduce my jobs and try again. Sorry to be a bother. I really appreciate the feedback though! It built when I set it to -j3. Glad to hear it works. |
