Some notes on installing apps in gentoo x86_64

This post lists all the problems I have encountered during updating gentoo using #--------------update the system weekly----------------------------

# emerge -auDvN  --keep-going world 

#---------------problem in installing evince----------------------------

# emerge -av evince 

configure: error: "PDF support is disabled since poppler-glib library version 0.20.0 or newer not found" solve:

# emerge -av poppler 

#---------------problem in installing net-libs/gupnp-igd-0.2.1----------------------------

Solve:

add the follow line in /etc/portage/package.keywords/net-libs

>=net-libs/gupnp-igd-0.2.2-r1

solved #-------------- install systemd on gentoo and use Grub 2 to boot it -------- there are two important information that one needs to follow: [1]: How to set new manuentry? [2]: How to add a new vmlinuz in folder /boot/ Here are successful example of menuentries in /boot/grub/grub.cfg

one can write these to /boot/grub/grub.cfg


menuentry 'Gentoo write by myself' {
        root=hd0,2
        linux /boot/vmlinuz-3.10.7-gentoo root=/dev/sda2 init=/usr/lib/systemd/systemd
}

menuentry 'Gentoo write by myself UUID' --class gnu-linux --class gnu {
        root=hd0,2
        linux /boot/vmlinuz-3.10.7-gentoo root=UUID=671f9d17-5de7-4fe7-a6bf-f1096f4efe29 init=/usr/lib/systemd/systemd
}

 ------- The problem on the networkmanager after updated to systemd and gnome 3 ----------------- 

The networkmanager in gentoo installed at my laptop and desktop failed to work after updating to systemd and gnome3. To find out the problem, I use:

systemctl status NetworkManager
 

which says:

The overwriting error message was: Could not load plugin 'ifnet': /usr/lib64/NetworkManager/libnm-settings-plugin-ifnet.so: cannot open shared object file: No such file or directory 

To resolve this problem, one needs to delete ifnet in the file /etc/NetworkManager/NetworkManager.conf

[main]
#plugins=ifnet,keyfile
plugins=keyfile
no-auto-default=00:26:6C:09:9F:1C,

[ifnet]
managed=true
auto_refresh=false

There is one thing to be reminded: alternatively, one can use wicd as a temporary resolution. However, I found the wicd is quite unstable in my gentoo system than that in Ubuntu. #------ Important note on updating kernels ----------------- I had one bad experience in updating kernel of my PC. after new kernel is selectecd, the module that has been selected has been gone completely! This means that I have to look for every module selected in the kernel! To avoid this problem happen again, One should backup file /usr/src/linux/.config before any updates on kernels!

Problem:

Solution: enabling all the falgs
echo ">=app-i18n/fcitx-4.2.7 lua opencc snooper" >> /etc/portage/package.use/app-il8n
