QDSfit

Install instructions

In order to install QDSfit on your computers home directory use the setup.py script provided.

Execute following commands on a shell prompt to get tho most current version and install the program in the local folder in your home directory:

hg clone https://chaos3.fkp.physik.tu-darmstadt.de/diffusion/QD/QDSfit/
cd qdsfit
python setup.py install --prefix=$HOME/local

This will fail most probably due to the PYTHONPATH variable not being set, you will get the following message:

running install Checking .pth file support in /autohome/markusro/local//lib/python2.7/site-packages/ /usr/bin/python -E -c pass TEST FAILED: /autohome/markusro/local//lib/python2.7/site-packages/ does NOT support .pth files error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not on PYTHONPATH and which Python does not read ".pth" files from. The installation directory you specified (via --install-dir, --prefix, or the distutils default setting) was:

/autohome/markusro/local//lib/python2.7/site-packages/

and your PYTHONPATH environment variable currently contains:

''

Here are some of your options for correcting the problem:

• You can choose a different installation directory, i.e., one that is on PYTHONPATH or supports .pth files

• You can add the installation directory to the PYTHONPATH environment variable. (It must then also be on PYTHONPATH whenever you run Python and want to use the package(s) you are installing.)

• You can set up the installation directory to support ".pth" files by using one of the approaches described here:

Please make the appropriate changes for your system and try again.

The only thing missing for the install is (according to the output):

export PYTHONPATH=/autohome/markusro/local//lib/python2.7/site-packages/
python setup.py install --prefix=$HOME/local

In order to access the program more easier, you have to set your PATH variable to the proper direcotry:

export PATH=$PATH:$HOME/local/bin

Both export commands should be in the shell start up file (.bashrc), then there is no need to type this every time you open a new window. You can then start QDSfit in a terminal by typing qds.py in any directory.

Happy fitting!
