# 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
|
||
|
|

|
|
> 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.
