Development version of CRPropa. Use on your own risk.

1. Download the latest data archive from https://crpropa.desy.de/Interaction_data and extract to CRPropa3/data

2. CRPropa uses CMAKE to configure. From the build directory call ccmake or cmake

    cd build
    ccmake ..  
   

3. Afterward configuring run make and make install as usual

    make
    make install 
   

The install path can be set with -DCMAKE_INSTALL_PREFIX=/my/path or with the option browser when using ccmake.

Notes for Intel Compiler:
use -DCMAKE_SHARED_LINKER_FLAGS="-lifcore" -DCMAKE_Fortran_COMPILER=ifort

For backwards compatibility CRPropa 3 can be steered via XML cards ($cropra-xmlrun some_steeringcard.xml) However, CRPropa 2 does not fully enforce the XML-1.0 standard (http://www.w3.org/XML). To comply with the standard a few modifications to exisisting steering cards might have to be made. Modification are

1. XML-cards can have only one root node. The root node is

    <CRPropa>
    ...
    </CRPropa>
   

2. All nodes including the optional header node need to be closed, e.g.

    <?xml version="1.0" standalone=no?>
    <Option1> ... </Option1> or
    <Option2/>
   

3. Values need to be embraced by quotes, e.g.

    <NumTrajectories="1000"/>
