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

[Laurence Perkins]

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.

Sorry for the late reply,

I found this commit

of last November, which might be the reason.
2.5.4 might be the last version with such support.

I emerged manually changed ebuild  and  $( rpcinfo -p localhost |  
grep nfs

)
explicitly indicates the version 2 of nfs, which runs successfully.

Thanks again for your dedicated and detailed reply,
and also the bottom-posting reminder.


Best regards :)

I don't fully understand the interactions and relationship, but there  
are obviously some differences between the kernel nfs and userland  
nfs.  Glad you got it working for you.
