Installation
============

  * If you install from a Debian package you can skip the following points, install it , and then go directly to the code invocation section

  * Using Git, sources can be retrived with the following command ::

      git clone https://gitlab.esrf.fr/mirone/pyhst2

  * If you compile on a Debian system, for a local installation you can use  ::

	export TD=${PWD}/dummy/	
	python setup.py install --prefix ${TD} 

    then to run the code you must do beforehand ::

	export PYTHONPATH=${PWD}/dummy/lib/python2.7/site-packages
	export PATH=${PWD}/dummy/bin/:$PATH

    then go to the section Code Invocation to see how to run the code.
    You can disable compilation of CUDA modules by choosing the option in setup.py

  * If you generate a Debian package and install it, then it will be in the standard directories and you dont have to set PATH and PYTHONPATH


  * If you  have a non standard cuda installation ( if you are not on a Debian system )  you have to provide the cuda home ::

	export CUDAHOME=/usr/local/cuda-4.0.17

    for example

  * Examples :
        There is an archive containing datas for tests by anonymous ftp at ::

        by the way you'll find there also the documentation.
