LHAPDF

GiBUU has the option to be linked against ​libLHAPDF v5. Please note: the newer version 6 is not supported! This may be a useful option in connection with initialization using PYTHIA.

You can enforce this by initiating the compilation by the command make PDF=LHAPDF ....

In order to do so, you have to place a copy of 'libLHAPDF.a' in the directory 'objects/LIB/lib/', e.g. cp /usr/lib/x86_64-linux-gnu/libLHAPDF.a objects/LIB/lib/.

If you are encountering error messages like ...relocation truncated to fit: R_X86_64_PC32..., you have to recompile the library for a large memory model. A succsessful approach may be:

    cd ./lhapdf-5.9.1
    export CXXFLAGS="-mcmodel=large"
    export FCFLAGS="-mcmodel=large"
    ./configure --disable-pyext --disable-octave --prefix=$HOME/TMP
    make
    make install 

The option '-mcmodel=large' is implemented in the default GiBUU Makefile.
