RE: [gentoo-user] gcc 12.1.1 compile error on loongson2f Yeeloong

[Laurence Perkins <lperkins@openeye.net>]

Turning on zswap or, better yet, setting up a zram swap with a file to back it helps quite a bit on swapping since a lot of the data in question is highly compressible.

Additionally, disable the "pipe" compiler option in make.conf so that it writes intermediate files out to disk instead of trying to keep them in memory.

And finally, if you have a more powerful machine sitting around, look into distcc and/or setting up a binhost.  You'll be much happier in the long-run.

Hmm. 1G ram and 1G swap is not much memory for building gcc.
You could check dmesg and syslog for out-of memory kill messages occurring during your builds.

It would be easy to try again specifying MAKEOPTS="-j1".  Also make sure that you have no unnecesary other processes running during the build - especially memory hogs like a web browser.

You could add swap, but if you are doing much swapping it will be intolerably slow.

I would also arrange for some extra cooling of the laptop just in the load is causing overheating.
