GCC build logs

All tries to compile GCC above 9.2.0 on 32bit KVM machines (each got more than 3GB RAM) fail.

* If you need support, post the output of `emerge --info '=sys-devel/gcc-9.3.0-r1::gentoo'`,

Comment 1 Ionen Wolkens gentoo-dev

> cc1plus: out of memory allocating 24082176 bytes after a total of 50466816 bytes
Seems just ran out of ram. Try lower MAKEOPTS=-jX value (with your ram I'd suggest -j2), could also add some swap.

I'd suggest support channels (forums/IRC/etc..) if need more help.

Comment 2 PetaMem R&D 2020-10-20 00:05:11 UTC

The -j 1 has been tested already

compare https://bugs.gentoo.org/739552

32bit machine with 3.3GB RAM + 1GB swap cannot compile anything GCC 9.3.0 or later even with -j 1

9.2.0 works with -j 4, without swap and with 2GB RAM
