Hi,

I have been trying to compile gentoo-sources-3.13.3 with genkernel, but it fails with message (in /var/log/genkernel.log):
Code:
  CC      drivers/video/console/bitblit.o
drivers/video/console/fbcon.c: In function ‘fbcon_clear_margins’:

How can I check what really went wrong (and hopefully correct it)?

in /var/log/messages I see only some openswan- and thermald-related stuff and dmesg apart from some wifi stuff gives me:

This will not answer your question, just because I do not know why it fails.
May be incompatible options or compiler flags.

But you can try following:

Code:
#!/bin/sh

env-update && source /etc/profile
emerge -auvNDt --with-bdeps=y --keep-going world
revdep-rebuild
rm /var/cache/revdep-rebuild/*.rr


before compiling new kernel.

I am personally do not use genkernel, because I don't understand it's purpose.

In my case the script
Code:

#!/bin/bash

#make localmodconfig
#make distclean
#make clean

cd linux
make menuconfig
make
make install
make INSTALL_MOD_STRIP=1 modules_install
cd ..


located in /usr/src does all work.

you just need copy you .config from previous version
and run that script. otherwise uncomment 3 lines in the beginning.

Well, I am also not using initrd, because of no need. But you can just add one more line to update initrd.
