Ubuntu – How to install root-cern

11.04installationrootx11

Cern's ROOT environment installs fine on 10.10, and is even available in the Software Center, but it will not install or compile on Natty because the x11 directories are in new locations.

I can redefine the paths, but then I get compile errors because only gcc 4.3 is supported through ROOT and Natty uses 4.5. I've given up and gone back to 10.10, but my question is, after installing ROOT on Maverick, if I upgrade back to Natty, will my old software still work with these new directory paths?

It's a pitty that root is not in repository anymore (applies for Ubuntu 11.04). Here is a way

HOW-TO install `root` on Ubuntu Natty (x86):

DEPENDENCIES:

sudo aptitude install gcc g++ make binutils \
                      libx11-dev libxpm-dev libxft-dev libxext-dev

OPTIONAL DEPENDENCIES: (I've this installed)

sudo aptitude install cmake \
                      gsl-bin libgsl0-dev \
                      liblzma2 liblzma-dev \
                      libgmp3c2 libgmp3-dev \
                      libpcre3 libpcre3-dev \
                      zlib1g zlib1g-dev

HOW TO INSTALL:

wget ftp://root.cern.ch/root/root_v5.30.00.source.tar.gz
tar -xzvpf root_v5.30.00.source.tar.gz
cd root

WHERE_TO_INSTALL_ROOT=/usr/local     ## feel free to change this
./configure linux \
            --with-x11-libdir=/usr/lib/i386-linux-gnu \
            --with-xft-libdir=/usr/lib/i386-linux-gnu \
            --with-xext-libdir=/usr/lib/i386-linux-gnu \
            --with-xrootd-opts=--syslibs=/usr/lib/i386-linux-gnu \
            --prefix=$WHERE_TO_INSTALL_ROOT

make
# sudo make install                     ## sudo needed at least for for /etc/root
# NEVER use make install in modern distros. Instead use:
sudo checkinstall --pkgname=root-framework --fstrans=no --strip=no make install
sudo 

cd $WHERE_TO_INSTALL_ROOT
source bin/thisroot.sh
root                                  ##  :-)   works...
       .Q                             // to quit root

NOTE: At a time of writing this 5.30/00 was latest and recommended version. Feel free to change this to other (I suggest recommended) version available at time you are reading this.

Ubuntu – Migrating to Natty (or any other future versions of ubuntu)

How do you save the configuration files of certain application like
for instance Thunderbird, Firefox?

To backup your apps data, you need to look in your Personal Folder for the .(hidden, press CONTROL + H to see them) folders. For example, Firefox (and other Mozilla apps) saves your personal data in a folder named .mozilla. Thunderbird does it using a folder named .thunderbird.
Others, Google Chrome/Chromium for example, use the .config folder, having a sub-folder there. (ex, .config/google-chrome)

To backup this settings, just copy the desired folders, just remember where they were before pasting them back.

When you copy an app folder, you copy ALL its preferences, history, databases, etc, so your bookmarks, extensions and other personal data are saved.

I have some applications like MATLAB and Maple (Based on JAVA) installed.
When I migrate, can I just copy the entire installation folder to the
new version of Ubuntu?

Yes, you can do that, but only with applications that were fully installed in that directory. Some apps install the main app in your home directory, but some libraries, or multimedia files (such as icons) in other folders. Be careful with this, the best is to reinstall, but you can use them.

*you should also check the compatibility, but they should work file

When doing a backup which folders should be backed up?

The most important folder is /etc, mostly because you may have modified a few files, like the Samba configuration, the SSH server configuration, the hosts file, and some other configuration that you may also have changed without knowing and would be better to keep rather than go back to the defaults ones (like the updates preferences, etc)

Other folders depends on what you have installed and/or modified (eg, XAMPP is installed on the /opt directory, and the configuration files reside in its own folder)

I have BURG installed. How can I do a backup of it?

I'm not exactly sure, i guess you can just backup the installed themes (if any). Reinstall in the new Ubuntu installation and restore. But again, it depends on what you have modified.

When I perform the clean install of ubuntu, would GRUB (bootloader)
be removed and in anyway jeopardize my windows installation?

No, GRUB is never removed, it may be upgraded, but this wont affect at all you Windows installation. Besides, remember you have BURG, which modifies GRUB's behavior

How do I make a backup of all my PPA and would they be compatible to the newer
version of ubuntu when I restore them?

The only way I know to do this is to manually backup all your .list located at /etc/apt

You should copy the sources.list and all the files located at /etc/apt/sources.list.d/

I hope to have answered all your questions. ;)

Ubuntu – Must I enable the root account to install Matlab

As explained here, you do not need to enable root logins to run commands as root. That's what sudo and its graphical frontends (like gksu/gksudo and kdesudo) are for.

Since install runs a graphical installer, and you can run it (but not as root) like ./install, you can run it as root with:

gksu ./install
