[Gentoo] Kpaint

Add some dependent package for kdegraphics-meta

printf ">=dev-libs/libpcre-8.38-r1 pcre16\n \

>=dev-qt/qtcore-5.5.1-r1 icu\n" \
>>  /etc/portage/package.use/kpaint

Start to install package

USE="icu" emerge --oneshot  =dev-libs/libxml2-2.9.4 --buildpkg kde-apps/kdegraphics-meta

Explain “–oneshot =dev-libs/libxml2-2.9.4”
When install this kpaint will appear two version of libxml2.(dev-libs/libxml2-2.9.4 & dev-libs/libxml2-2.9.3).
So I choose dev-libs/libxml2-2.9.4 to install with this package.

Requested 'libmuffin >= 3.0.0' but version of libmuffin is 2.8.4

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables CINNAMON_CFLAGS
and CINNAMON_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

A:

$ pkg-config --exists --print-errors libmuffin 3.0.5
Package 3.0.5 was not found in the pkg-config search path.
Perhaps you should add the directory containing `3.0.5.pc'
to the PKG_CONFIG_PATH environment variable
No package '3.0.5' found

$ pkg-config  --print-errors --exists  "libmuffin >= 3.0.5"
Requested 'libmuffin >= 3.0.5' but version of libmuffin is 2.8.4

$ export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig
$ pkg-config  --print-errors --exists  "libmuffin >= 3.0.5"

[Gentoo] How to backup & restore gentoo os

Backup system by using tar
Boot from the liveCD

mkdir /mnt/gentoo
mkdir /mnt/backup
mount /dev/sda2 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot
mount /dev/sda3 /mnt/gentoo/home/happy

time tar -cvvjpf /mnt/gentoo/home/happy/gentoo_backup.tgz -C /mnt/gentoo

Restore the tar file into system

mount /dev/sda2 /mnt/gentoo
mount /dev/sda1 /mnt/gentoo/boot

tar xvvfh gentoo_backup.tgz -C /mnt/gentoo

Following command need to do, otherwise when execute chroot won't find /bin/bash under gentoo enviroment.

tar -xmvvf stage3-amd64-20150730.tar.bz2 -C /mnt/gentoo
tar -xmvvf portage-20150804.tar.xz       -C /mnt/gentoo/usr/

After restore the system need to create new fstab.
Make sure /dev/sda2 will boot under read/write mode.

genfstab -U -p /mnt/gentoo >> /mnt/gentoo/etc/fstab

Install two package, one is for boot, the other one is for kernel & initramfs.

# emerge genkernel (Gentoo automatic kernel building scripts)

# mkdir -p /etc/portage/package.accept_keywords
# echo "sys-boot/gummiboot" >> /etc/portage/package.accept_keywords/efi
# emerge sys-boot/gummiboot

Compile kernel & install kernel first.

cd /usr/src/linux
make
make modules_install
make install 

After install will install following stuff under /boot

config-4.4.6-gentoo
System.map-4.4.6-gentoo
vmlinuz-4.4.6-gentoo

Using genkernel to create initramfs under /boot.

# genkernel --install initramfs

Using gummiboot create booting stuff.

# gummiboot --path /boot install

Edit /boot/loader/entries/gentoo.conf to make booting configuration.

title Gentoo Linux  (Title name need the same)
initrd /initramfs-genkernel-x86_64-4.4.6-gentoo (Init image)
linux /kernel-genkernel-x86_64-4.4.6-gentoo  (Kernel image)
options root=/dev/sdaX rw  (X = root filesystem)
