Get git

Here is an example how to download and install git. Find out your distribution and proceed accordingly:

SLES 11

Get the SLE SDK media, add it as repository, install git using

yast -i git

SLES 10

This example downloads version 1.7.6 of git and must be executed as root user under a default installation of SLES 10:

  • Download git
wget http://www.kernel.org/pub/software/scm/git/git-1.7.6.tar.gz
  • if this does not work, you may have to set your proxy and redo it like this
export http_proxy=proxy.company.com:8080
wget http://www.kernel.org/pub/software/scm/git/git-1.7.6.tar.gz
  • unpack it
tar xvzf git-1.7.6.tar.gz
yast -i zlib-devel python-devel
cd git-1.7.6/
./configure && make -j8 && make install
  • test it by calling
# git version
git version 1.7.6

How to ...
