Following is guide for installation of QGIS 1.8.0 in GNU Debian-cut and wheezy:
Update Packages for Wheezy for i386 and amd64 are available at:
deb http://qgis.org/debian wheezy main
deb-src http://qgis.org/debian wheezy main
To add the the qgis.org repository public key to your apt keyring, type:
gpg--export--armor997D3880|sudo apt-key add-
sudo apt-get update
sudo apt-get install qgis
If you also want python plugins make sure to install the optional python package:
sudo apt-get install python-qgis
If you want the GRASS plugin make sure to install the optional package:
sudo apt-get install grass
sudo apt-get install qgis-plugin-grass
As to date i.e., 30/09/12, qgis-plugin-grass was not installable because it required a package grass641 which is not available in any repo (stable, testing, unstable, experimental) of debian. I have reported the bug to QGIS issue tracking. For now, I upgraded to nightly build of qgis by changing sources.list as:
deb http://qgis.org/debian-nightly wheezy main
deb-src http://qgis.org/debian-nightly wheezy main
Then followed the steps of installation heading as described above and successfully install all three packages, i.e, qgis, python-qgis and qgis-plugin-grass. QGIS 1.90 – Master was installed successfully.
LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents. One of great benefit of LaTeX is that it can be converted easily to postscript, pdf or html. There is excellent collection documentation and books on LaTeX website which can be helpful to get started with LaTeX.
Following packages are required to work with LaTeX in Debian:
texlive – the base TEX/LATEX setup.
emacs (with auctex) – a Linux editor that integrates tightly with LATEX through the add-on AucTeX package.
ghostscript – a PostScript preview program.
xpdf and acrobat – a PDF preview program.
imagemagick – a free program for converting bitmap images.
gimp – a free photoshop look-a-like.
inkscape – a free illustrator/corel draw look-a-like.
Following is a simple getting started tex file that should be save with name of hello.tex using emacs or gedit.
Above file can be compile either directly from emacs or from terminal by following command:
The result will be a pdf file with following writing:
During installation of Debian Linux, you are required to enter partition scheme. The easiest way is to use entire disk and recommended partition or you can decide yourself the partition. One of helpful detail of partition is given below:
swap = 2GB
file type for rest of partition = ext4
/ = 6GB
/opt = 10GB
/srv = 3GB
/tmp = 6GB
/usr = 10GB
/usr/local = 10GB
/var = 5GB
and finally for /home = rest of space left (but atleast 10GB).
This partition is on Logical Volume Manager – LVM. You can edit each partition later using GParted Live CD.
Note: This recommended partition is for end user’s laptop and desktop. For servers, /srv partition should be big enough for running services and /var partition must also be adjusted for maintaining log files.
