emerge --sync       # entspricht "aptitude update"

Am Beispiel "bc":

<petrvs> debdog: emerge -n eix; eix-update; eix -e bc
<petrvs> debdog: emerge -Opv bc
<petrvs> debdog: emerge -n pfl; e-file bc | less

emerge pfl; e-file [command|filename]

< i4dnf> jesdog - packages.gentoo.org
< i4dnf> jesdog - and http://gpo.zugaina.org
< i4dnf> (last one searches in all overlays)
< i4dnf> emerge eix
< i4dnf> eix xcdroast

i4dnf has this in /etc/portage/make.conf EMERGE_DEFAULT_OPTS="--ask --verbose --autounmask=n --ignore-built-slot-operator-deps=y"

<i4dnf> this might be useful too: FEATURES="parallel-fetch candy collision-protect fixlafiles splitdebug"

<debdog> i4dnf: about multilib. https://wiki.gentoo.org/wiki/Eudev "abi_x86_32". I need at least one 32bit programme and perhaps wine, too.should I add that to USE?
<debdog> also, I have added "multilib", does that mean everything will be compiled with 32bit, too? or is there a way to tell emerge what libs and progs I actually need in 32bit?
<i4dnf> debdog - emerge wine whill whine about the ones that want abi_x86_32
<i4dnf> then add those to /etportage/package.use/somefilename like so
<i4dnf> app-cat/app-name abi_x86_32
<debdog> so I don't need to add this to eudev?
<i4dnf>  /etc/portage/package.use/$somefilename *
<debdog> and I should probably remove "multilib " from USE?
<i4dnf> if it needs 32 bit udev you have to (though i doubt it)
<i4dnf> leave multilib on

<i4dnf> debdog - btw, to check current emerges, emerge genlop, then genlop -c

<i4dnf> emerge -1v app-portage/cpuinfo2cpuflags then  cpuinfo2cpuflags-x86
<i4dnf> btw, you might want to run dispatch-conf asap <-- "config files in '/etc' need updating"

kernel/bootmgr

Next select the exact processor type. It is also recommended to enable MCE features (if available) so that users are able to be notified of any hardware problems. On some architectures (such as x86_64), these errors are not printed to dmesg, but to /dev/mcelog. This requires the app-admin/mcelog package.

cd /usr/src/linux
make [x|menu]config
make -j5 && make -j5 modues_install
make install
cp /boot/vmlinuz-<version> /boot/efi/boot/bootx64.efi
genkernel --install initramfs

make clean  # nur bei compile errors benötigt
