It's possible with Gentoo to keep a version of a package and mark it as no updatable.
To do that, you have to modify (or create if it doesn't exist) the file /etc/portage/package.mask.
Then add the package version in this file.
Example :
vi /etc/portage/package.mask
>x11-drivers/nvidia-drivers-180.60
So when you will make emerge -p world, you will see :
[ebuild R ] x11-drivers/nvidia-drivers-180.60
So the package can't be update.

Dead key and compose key definition
Here is a good definition of what is dead key and compose key that i found on wiki.linuxquestions.org :
If you press a ` and an e, you get an è. In this case the key ` is called a dead key because it is at first stroke dead. A bit more tricky is the compose key. Press the compose key and then type two keys, and both keys will be combined. E.g. type the compose key, then the comma, then c and the outcome is ç.

Go installation on Gentoo
Go installation on Gentoo was with no error for me.But, here is some steps to permit you to install faster :
- Add variable in user's bashrc :
export GOBIN=$HOME/go/bin/
export PATH=$GOBIN:$HOME/google/depot_tools:"$PATH"
#Go
export GOROOT=$HOME/go
export GOARCH=386
export GOOS=linux
Note : I've create $HOME/go and $HOME/go/bin.
- source ~/etc/bashrc
- If you don't have hg, you will need to install mercurial : emerge dev-util/mercurial
- Add variable in user's bashrc :
export GOBIN=$HOME/go/bin/
export PATH=$GOBIN:$HOME/google/depot_tools:"$PATH"
#Go
export GOROOT=$HOME/go
export GOARCH=386
export GOOS=linux
Note : I've create $HOME/go and $HOME/go/bin.

Chrome OS vs Linux,Windows,Mac ...
Google has announced its new operating system based on Internet.
This is revolutionnary because all application are on internet.So it changes all that we know.With this sort of sytem, we can't compile, customize our system.Other people made it for you.
Moreover, we hear that Microsoft will do the same thing with Midori.
So i have many question :
- What is the future of traditionnal OS ?
- Does Linux have to follow internet operating system like Chrome OS ?
- How to customize an web OS ?
- What is the future of Gentoo ?

chroot : Enter in a new environment
chroot is a unix command which permits to change root dir.
It permit to enter in a new environment in your terminal.So you can add an other system just in other window.For example, I launch my experimental gentoo in a terminal and I make a chroot. My terminal is similar to that : (chroot) localhost / #
The major advantage is I can compile and make update easily without having restart my computer.
Here is how you can do to enter in a new environment :
1) Mount experimental partition (depends on your system):
mount /dev/sda6 /mnt/gentoo
2) Mount /proc and /dev
Mount file system /proc in /mnt/gentoo/proc permit at the installation to use information provide by the kernel.Same things for /dev.
mount -t proc none /mnt/gentoo/proc
mount -o bind /dev /mnt/gentoo/dev
3) Enter in a new environment :
You can do it in three steps.First you change the root directory by making a chroot.Then you create the environment variable whit env-update.And to finish, you load this variable in memory wy using source.
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
export PS1="(chroot) $PS1"

KDE4.3 test on Gentoo
I've test kde4.3 with Gentoo on my experimental partition.
Compilation is OK and i launched kde but i've some problem with my keyboard.(If you hit on keyboard, the letter is repeat severeal times)
To conclude, I think that we have to wait a little more before install it.

How to solve : All ebuilds that could satisfy ... have been masked.
Problem
During update, you have the following message :
!!! All ebuilds that could satisfy "x11-wm/compiz" have been masked.
!!! One of the following masked packages is required to complete your request:
- x11-wm/compiz-0.8.2-r3 (masked by: ~x86 keyword)
Solution
You have to put the package name in package.keywords.
It's because you have compiled in masked mode and when you make an update it try to search in masked package but it is not authorized.So you have to tell it that it can do by adding in package.keyword file.

Hudson : Failed to create /dev/null/.m2
Problème :
When you launch an Hudson build, you have the following error: Failed to create /dev/null/.m2
Solution :
ADD MAVEN_HOME same as HUDSON_HOME at JAVA_OPTS variable in startup Tomcat script :
vi /etc/init.d/tomcat-6
# Activate Logging
if [ -r "${CATALINA_HOME}"/bin/tomcat-juli.jar ]; then
JAVA_OPTS="${JAVA_OPTS}
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager \
-Djava.util.logging.config.file=${CATALINA_BASE}/conf/logging.properties"
fi
JAVA_OPTS="$JAVA_OPTS -DHUDSON_HOME=/home/hudson
-DMAVEN_HOME=/home/hudson"

Unable to create the home directory '/dev/null/.hudson'
Problem :
You deploy hudson.war in Tomcat 6 and when you want to show hudson main page, you have this error :
Unable to create the home directory '/dev/null/.hudson'. This is most likely a permission problem.
To change the home directory, use HUDSON_HOME environment variable or set the
HUDSON_HOME system property. See Container-specific documentation for more details of how to do this.
Solution :
- Create a home directory for Hudson.
mkdir -p /home/hudson
chown -R tomcat:tomcat /home/hudson/
ls -al /home/hudson/
drwxr-xr-x 6 tomcat tomcat 4096 Oct 3 18:45 hudson
Note : I've notice that you must restart Tomcat for that's work.
- Add the HUDSON home directory for Tomcat in the tomcat startup script :
vi /etc/init.d/tomcat-6
Search JAVA_OPTS
Then add some line after :
JAVA_OPTS="$JAVA_OPTS -DHUDSON_HOME=/home/hudson"
Example :
...
# Activate Logging
if [ -r "${CATALINA_HOME}"/bin/tomcat-juli.jar ]; then
JAVA_OPTS="${JAVA_OPTS} -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager \
-Djava.util.logging.config.file=${CATALINA_BASE}/conf/logging.properties"
fi
JAVA_OPTS="$JAVA_OPTS -DHUDSON_HOME=/home/hudson"
...
- Modify the Tomcat user file (vi /etc/tomcat-6/tomcat-users.xml )
cf AdministrationHudson
- Then Restart Tomcat.

Installation KDE4 : directory package.keywords
When i install KDE4, I was surprised to see in the documentation : cd /etc/portage/package.keywords : Manuel KDE4
However, on my computer there is only a single file package.keywords
I search on the web and i found the solution :
/etc/portage/
Any file in this directory that begins with "package." can be more than just a flat file. If it is a directory, then all the files in that directory will be summed together as if it were a single file.

Search ebuild faster with eix
Problem :
You can search ebuild with emerge -s.Is there a faster way to search packet ?
Solution :
It exists a tool to make search faster on portage tree and other non official trees : eix
0) Install it :
1) Update it (you have to do this after emerge --sync) : update-eix
2) Search a packet (for example mediawiki) : eix -s mediawiki
You can search ebuild with emerge -s.Is there a faster way to search packet ?
Solution :

How do you update you gentoo ?
You have to update your gentoo frequently.
Here is some steps you have to do :
1) Update portage
$ emerge --sync
2) Update the System
$ emerge -p system
$ emerge -u system
3) Update Software
$ emerge -p world
$ emerge -u world
4) Launch Optimisation
If you want that executable start faster, try this :
$ prelink -amR (Very Very Useful ! see my documentation about installation and use prelink)
5) Search Optimisation
$ update-eix
See on eix.This command will permit you to run faster.
Important notes :
- It is possible to update your configuration file with etc-update.
If you are a beginner, use it carrefully because you can destroy you configuration.Make a backup before !
- -p permit to check if they are some packets to update.

emerge x11-drivers/nvidia-drivers compilation failed Could not find a usable .config
Problem :
When you update x11-drivers/nvidia-drivers, the compilation fails.
Example :
* Could not find a usable .config in the kernel source directory.
* Please ensure that /usr/src/linux points to a configured set of Linux sources.
* If you are using KBUILD_OUTPUT, please set the environment var so that
* it points to the necessary object directory so that it might find .config.
*
* ERROR: x11-drivers/nvidia-drivers-185.18.31 failed.
Solution :
You aren't on the good kernel.This is because during update the link is change.
If you do :
ls -al /usr/src/
lrwxrwxrwx 1 root root 22 Aug 16 16:30 linux -> linux-2.6.30-gentoo-r1
drwxr-xr-x 22 root root 4096 Nov 29 2008 linux-2.6.26-gentoo-r3
drwxr-xr-x 23 root root 4096 Dec 6 2008 linux-2.6.27-gentoo-r4
drwxr-xr-x 23 root root 4096 Aug 9 13:36 linux-2.6.30-gentoo-r1
You see that the link points on an other kernel and you have'nt compile source for this kernel.
That's why there is no .config files.
So there is two solutions :
- Compile new kernel sources.
- Point on good kernel.
We will take the easier solution : Select your kernel.
To do that :
# eselect kernel list
Available kernel symlink targets:
[1] linux-2.6.26-gentoo-r3
[2] linux-2.6.27-gentoo-r4
[3] linux-2.6.27-gentoo-r5
[4] linux-2.6.27-gentoo-r7
[5] linux-2.6.28-gentoo
[6] linux-2.6.28-gentoo-r1
[7] linux-2.6.29-gentoo-r2
[8] linux-2.6.29-gentoo-r4
[9] linux-2.6.30-gentoo-r1 *
[10] linux-2.6.30-gentoo-r2
Then you can point on the good kernel :
# eselect kernel set 9
If you execute eselect kernel list, you will see a start on the select kernel.
Then you can make an update of the package :
#emerge -u x11-drivers/nvidia-drivers
When you update x11-drivers/nvidia-drivers, the compilation fails.
Example :
* Could not find a usable .config in the kernel source directory.
* Please ensure that /usr/src/linux points to a configured set of Linux sources.
* If you are using KBUILD_OUTPUT, please set the environment var so that
* it points to the necessary object directory so that it might find .config.

shell read properties file
|
You want to read a properties files that is similar to :
vi test.properties
VAR1=zest
VAR2=blop
VAR3=toto
MAIL=test@ty
ALIAS=monalias
You want also use this variable.
Solution
You have to read line by line and make an export of each line.
Note : It's just a test method.
#!/bin/ksh

test -f $FILE
if [ $? -ne 0 ];then
echo "Fichier de propriete inexistant:$FILE"
exit 1
fi
echo "Lecture..."
while read ligne
do
if echo "$ligne" |grep "=" 1>/dev/null
then
VARNAME=`echo $ligne |cut -f1 -d=`
#echo $VARNAME
VARVALUE=`grep "^$VARNAME=" $FILE`
export $VARVALUE
#echo "export $VARVALUE"
fi
done < $FILE echo "VAR1:$VAR1" echo "VAR2:$VAR2" echo "VAR3:$VAR3" echo "ALIAS:$ALIAS" echo "MAIL:$MAIL" } readFileProperties

cannot set LC_CTYPE locale (gentoo)
Problem :
cannot set LC_CTYPE locale
environment variable LANG is fr_FR.utf8@euro
please check that your locale name is correct
Solution :
The problem is that LC_CTYPE was unknown.
In fact, you have to check that this variable value is correctly spell.
To do that, you can do : locale -a
Example :
$ locale -a
C
POSIX
fr_FR fr_FR.iso88591
fr_FR.iso885915@euro
fr_FR@euro
Next, you have to check in the configuration file :
On gentoo : vi /etc/env.d/02locale
Example :
vi /etc/env.d/02locale
LANG="fr_FR.iso885915@euro"
LC_COLLATE="C"
=> You must have LANG variable initializes with one of the result of the command : locale -a
If you want, you can also let every Linux user to configure their own variable.
vi ~/.bashrc
Example :
vi ~/.bashrc
export LANG="fr_FR.iso885915@euro"
export LC_ALL=C
cannot set LC_CTYPE locale
environment variable LANG is fr_FR.utf8@euro
please check that your locale name is correct
