pcmaster,

Google translate says the

kernel code model does not support PIC mode

What CPU do you have selected in the kernel.

The kernel supports several "code models" - they vary by arch. You shouldn't need to set it manually, its normally chosen by other settings.

Pastebin your kernel .config file.

Thanks. Finaly I found that the workaround suggested by Martin DiViaio in this bug worked for me:

https://bugs.gentoo.org/621848#c4

In my case it worked with KV_SUB="12", that is the kernel version I have installed.

PostPosted: Wed Jan 24, 2018 7:48 pm    Post subject: What to do after upgrade? Reply with quote

Apologies for posing this question, but I was able to upgrade gcc and to profile 17.0. The question not clear is whether I should then remove all older versions of GCC.
I am running 6.4.0-r1, but have tow older versions both masked. I've never been quite sure about uninstalling older versions.

TIA

A.S. Pushkin,

The only reason for keeping old masked gcc versions once you have moved to the /17.0/ profile is that its then only way to build something you need.
Its harmless to keep them on your system but you should only use them when there is no other option.

Hello.

Is it still planned to dump the 13.0 profile may 2018? Do you guys have any suggestions for the people who are not able to switch to 17.0 till then? Should we save the 13.0 profile
directory or will there be a 13.0 overlay somewhere?

thanks and cheers
